Relatively recently, dishwashers appeared in the homes of our compatriots. This device is appreciated not only by women, but also by men, because there is a lot of free time.
But even today, many people have a lot of questions on various topics related to dishwashers. Common questions include. Information on the correct installation of the device to the water supply system is also extremely necessary. Many people think that it is better to connect dishwasher directly to hot water. After all, the tariff for electricity increases almost daily, but hot water always in the tap. Why use electricity to heat water for a dishwasher?
Many experts ambiguously answer the question: “Is it possible to quickly and reliably connect the dishwasher to hot water?”. After all, not all manufacturers can give clear recommendations on this matter.
Connection
Of course, there are many models that can be connected to a water supply source. But all users must follow the recommendations and rules specified in the instructions for the device.
If you decide to connect the dishwasher directly to hot water, you should prepare a special filling hose. If a conventional hose is installed, this can lead to serious consequences.
Please note that all water supply hoses must be marked in red and blue. So the consumer can recognize the values at any time.
Benefits of connecting a dishwasher to hot water
Many experts agree with the opinion of thrifty consumers. Therefore, they give their advantages of connecting the dishwasher to warm water.
This method of connection significantly reduces the consumption of electricity in the house. After all, the device washes cutlery at a high temperature. The same thermal water is used for the last rinsing of dishes, which has a positive effect on its drying.
The washing process is much faster, because there is no time spent on heating the water in the tank.
The heating element in the device wears out more slowly, because it practically does not need to be used.
But, at the same time, many experts do not understand why, if there is hot water in the house, it is impossible to use a sink. It is so .
Disadvantages of connecting the dishwasher to hot water
Many experts recommend paying attention to the temperature of the water. If it exceeds 60 0 C, this may adversely affect the built-in filtration system. All damaged meshes of flow filters will quickly fail, which means that they will need to be changed regularly. But you can’t use the device without filters, because garbage will get into the dishwasher.
Hot water pressure is different from cold water. The difference between these indicators increases significantly, given that hot water enters the device through a cylinder in the boiler.
WITH hot water more garbage comes in, so additional filters should be used.
On water hoses designed for high temperature water, creases and kinks appear more often. Therefore, before installation, check whether the hose is under any physical activity. In this case, the hose may soften and break when water flows through it.
High temperature water also negatively affects the drain hose and nozzles of the machine. This shortens its lifespan.
Sometimes hot water can "stick" food to the surface of the plate during the first wash. And this will greatly complicate the process of cleaning dishes.
Everyone knows that problems with the supply of hot water happen much more often than with cold water. Suffice it to recall the summer (the time of repair and preventive maintenance), when the period of turning off hot water can be very long.
Often in dishwashers, the washing cycle takes place at a temperature of 50 0 C. If water with a temperature of 60 degrees comes in, this program may not be completed. After all, a dishwasher can heat water, but not cool it.
About the reasons why the dishwasher may not heat water.
Features of connecting to hot water
The device is connected to hot water in the same way as to cold water. But such an installation requires a number of features. So, how to connect the dishwasher to the water supply correctly?
- Read the instructions for the device well. Make sure the device is connected to hot water. Indeed, for example, for Bosch models, the water temperature should not exceed 20 0 C, which means that you only need to use cold water.
- Prepare a special inlet hose designed for hot water.
- Install a flow filter. It will additionally protect the dishwasher from hot water impurities. Install it between the pipe outlet and the inlet hose.
Before you start connecting the device, you must collect all the components. The inlet hose for hot water must be of high quality. Some manufacturers supply a similar hose with a dishwasher designed for such a connection.
Prepare the faucet tee. It must be used to connect the machine. In addition, it will help to shut off the water supply if necessary.
So, you need to prepare:
- hose;
- cleaning filter;
- special mixer;
- brass tee with stopcock;
- fum tape and wrench.
Connecting the dishwasher to hot water
To bring hot water to the dishwasher, you do not need to use special tools. using only hand strength. Well, for a reliable installation of a tee crane, you should use an adjustable wrench. Remember that the fum tape must be wound in the direction against the thread. It takes about 10 turns.
So, the connection sequence:
- We remember about safety, so we turn off the water. Otherwise, you can get scalded with boiling water.
- WITH water pipe plug needs to be removed.
- There is a thread at the end of the pipe outlet. Do not wrap fum-tape or tow on it.
- We fasten the brass tee. Check if the joints are hermetically sealed.
- We wind the fum-tape onto one terminal of the tee and fasten the end of the inlet hose well. We check that it freely reaches the body of the device.
- We install a plug on the second terminal of the tee.
- And the second end of the hose we install a flow filter
- We fasten this entire structure to the filling valve of the device.
At the end of all work, turn on the water and check the tightness of all connections. If everything is in order, you can test the operation of the device.
Other connection options
Often in expensive models of dishwashers, it is possible to connect the device to water in 3 ways:
- to hot;
- to cold;
- simultaneously to 2 sources.
The latter method is especially popular. Thanks to him, the equipment can independently mix 2 streams of water to the required temperature. So you can not only save energy, but also choose the desired washing mode.
But this method involves the use of a large number of hoses. And this does not always look aesthetically pleasing and is far from inconvenient to connect.
Traditional dishwasher connection
Almost all dishwashers are designed to be connected to cold water. This is spelled out in the instructions for the appliance, which indicates a clear sequence for installing kitchen equipment.
- Turn off the water supply tap;
- The mixer nut is unscrewed with a wrench and the thread of the pipe is released.
- Fum-tape or tow is wound.
- A tee is installed. At the same time, we take into account that the side outlet is in a convenient position for connecting the hose to the dishwasher.
- Installing the mixer.
- On the tee, we transfer the valve to the “closed” position. We open the general water supply and check the tightness of the joints.
- We install the dishwasher hose by screwing the plastic nut
Conclusion
A dishwasher is an indispensable device in every modern home. Correct installation guarantees long-term operation of the device. Should I connect the appliance to hot water? An unambiguous answer cannot be given, because there are many arguments both “for” and “against”. The manufacturer can judge everyone. After all, it is he who indicates in the product passport all the recommendations for its installation.
Remember, you should think carefully before installing the device without paying attention to the recommendations indicated in the instructions. This can harm only the dishes, but also the technique.
So, to which water it is better to connect the dishwasher (to cold or hot) - the owner of the device decides. It all depends on his preferences and desires. But as practice shows, the main advantage of hot water supply (reducing energy costs) does not turn out to be such. Especially if you take into account the possibility of possible device breakdowns and inconvenience in its operation.
What to do if - find out from our article.
A useful appliance in the kitchen is a dishwasher. It helps to save water, valuable time that can be spent on a good rest, communication with the family, doing household chores. If the family is large and everyone loves delicious homemade food, by the end of the day there is a lot of utensils left over from cooking and eating.
This wonderful device will easily cope with the task of washing dishes, the quality of the sink will surprise the demanding hostess. When the machine is purchased, it must be installed, connected. Below is step-by-step instruction, which will tell you how to connect the dishwasher with your own hands to the plumbing, cold, hot water, sewerage, electricity, how to choose the right place, how to build in appliances.
Dishwasher in the kitchen
Dishwashers are gaining great popularity and are often found in apartments and houses. Washing dishes in the machine is convenient, comfortable. The device allows you to save water consumption and electricity needed to heat water. It is not surprising that a dishwasher is present in many homes or is planned for the nearest acquisition. The best moment to make a purchase decision this device- kitchen refurbishment.
If the place is determined and prepared, you can install the machine at any time. Installation work is not difficult, they can be successfully completed independently. What do you need to connect a dishwasher?
The dishwasher does not require any special installation. After installing the machine, you will need to connect to the main networks:
- electricity
- plumbing,
- sewerage.
In some cases, you can connect the device to hot water, but not all models allow this method, this should be indicated in the instructions.
Preparing the installation site
First you need to decide on the location of the equipment. It is desirable to foresee the placement in advance in the design of the kitchen, but you can easily install it at any time if the necessary networks are nearby: water supply, sewerage, electricity.
The best option location - near the sink. Before buying, it is necessary to evaluate the amount of space available, because the appliances are offered in various sizes. To get extra space, it is worth giving up one kitchen cabinet.
Freestanding models have a standard width:
- 60 cm
- 45 cm
Standard depth - 60 cm, height - 85 cm. In most cases, the machines are equipped with legs that allow you to make slight adjustments (raise, lower by 2-4 cm). Some freestanding models allow you to mount under the worktop of the kitchen set, they remove the top cover. Built-in machines have similar dimensions.
Installing and connecting a built-in machine will require great accuracy in measuring the installation location. The built-in option must be provided at the stage of ordering kitchen furniture. When the machine is built in, any intervention is difficult or impossible.
An interesting solution is a compact dishwasher that is installed on the kitchen table. The compact model resembles appearance home microwave oven, does not require much space. Compact appliances will complement a small kitchen where it is impossible to put a standard size of appliances. Compact models are bought by tenants of rented apartments, childless couples, bachelors.
What kind of water can be connected?
The machine must be connected to a water supply, usually cold water. Some models can use hot water at 60°C. However, the profitability of this option is noticeable in the following situations:
- water is heated through the use of alternative energy sources (solar collectors, heat pumps);
- hot water is supplied by a boiler or gas heater, you can save a little, because the energy from burning gas is cheaper than electricity;
- water is heated by a solid fuel boiler, a fireplace with a water jacket.
The use of hot water is useful if the heating element burns out, replacing this component is expensive. Unfortunately, in modern technology, spare parts do not last too long, they are sold assembled, as a unit, so replacement is expensive. As the experience of the author of the article shows, this rule applies to little-known and popular brands present on the market. household appliances.
Before connecting to the water supply, make sure that the water:
- not too tough
- does not contain a large amount of iron, manganese.
What hardness is allowed?
- if the total hardness is less than 7 on the hardness scale - there is no need to use an air conditioner - the water is considered soft;
- if the total hardness exceeds 7, a water softener should be used.
When heated, the compounds contained in water decompose into insoluble carbonates, which form scale (a phenomenon known to people using electric kettles).
Increased water hardness can:
- damage the device
- significantly reduce the quality of washing.
To reduce stiffness, it is necessary to install appropriate main filters at the water supply inlet to the apartment or directly in front of the equipment.
Water connection
You can connect the water to the dishwasher yourself. Each machine is equipped with a hose for water supply. Depending on the manufacturer, the hoses have a length of:
If the hose is too short for the model you purchased, you need to purchase an extended version. It is not recommended to extend the water hoses by connecting them together, as this may cause water leakage at the joints.
An easy way to connect a dishwasher to the water is under the sink. High-pressure flexible hoses are suitable for these connections, which must be hidden in the sink cabinet (the hose is included with the machine).
To connect you need
- Turn off the main water supply faucet in the apartment.
- Unroll the pipe.
- Water is supplied to the sink through 2 pipes (cold and hot). A tee with a faucet for a typewriter is installed on a pipe with cold water. If the dishwasher is connected to hot water, a similar tee is installed on the hot water pipe.
- We fasten the high pressure hose to the faucet and to the machine.
System leak test
After installing the pipes, it is necessary to check the tightness of the system. The tightness is checked by opening the main tap in the apartment, and then after the first start of the machine.
It is important to check the pressure in the plumbing system. For the operation of the device, it is sufficient to provide water supply in a volume of at least 10-15 l / min, the water pressure must have the value specified by the manufacturer (range: 0.1-1 MPa).

Connecting the dishwasher to the sewer - options
Most dishwashers have their own hoses, tubes for draining used water. They have different lengths, but if necessary, the outflow pipe must be extended, while maintaining the necessary tightness.
Attention! To prevent unpleasant odors from appearing in the dishwasher, it is important to ensure that the Wastewater with proper bias.
If the sewer system is being built from scratch, it should be remembered that near the location of the device there must be an outlet to the sewer with a diameter of at least 4 cm, preferably with an inlet pointing upwards, possibly extending horizontally from the wall. The bent end of the flexible drain hose that the machine is usually equipped with must be placed in the drain pipe and secured to the wall with a special handle so that it does not fall out.
Connection to the sewer, photo
You can use a special rubber plug with a hose hole or a plastic sewer connection with a 1/2-inch connection to connect the drain hose.
If there is no sewer to which the dishwasher can be directly connected, a sink siphon can be used. You will need to replace the top siphon fitting with a tee to connect with a side connection. The design of some siphons includes a tee fitting for mounting a drain pipe, then you do not have to install anything additional. This connection is used to install the drain hose. To increase the tightness of the connections, you must additionally use clamps.
The minimum height of the drain hose is 40 centimeters. The height of the drain hole is usually specified by the manufacturer in the instructions. Compliance with this slope will protect against unwanted odors from sewer pipes.
Scheme. Drain height - installation rules
Electrical connection
All devices available on the market operate at a nominal voltage of 220 V, have an electrical cable with a plug.
Important! The socket must be grounded.
It is worth paying attention that, for safety reasons, when connecting to the mains, it is impossible to do. Dishwashers are equipped with a system that interrupts the water supply when there are malfunctions in the operation of equipment, internal leaks.
What can not be done!
- An extension cord cannot be used. According to safety regulations, the machine must be connected directly to a grounded socket.
- Location of outlets. If the appliance is installed next to a sink, there is an electrical outlet nearby and there is a danger of contact with water. Security should be considered - consider installing a moisture-proof outlet. This issue is especially important if children live in the house.
Using the above rules, you can easily connect the dishwasher to the networks with your own hands. It will take a little skill, basic tools, a tee, a faucet. Installation of the dishwasher is not difficult, it is important to follow the recommendations exactly. If the task is to do the installation professionally, to prevent sudden flooding of the apartment, it is better to entrust the work to a plumber.
Dishwashers, even with A+++ efficiency, use a certain amount of electricity to heat water. This raises a legitimate question for the buyer: is it possible to connect the dishwasher to hot water and not spend money on electricity? Let's try to figure it out.
Specifications
According to the technical specifications, most dishwashers work with water that is not hot 60 ° C, and units from Bosch do not exceed 20 ° C. This means that the excess temperature regime will definitely lead to a quick breakdown and loss of warranty repairs.
Causes of malfunctions:
- High water temperature leads to failure of the filtration system.
- Tap hot water is more polluted than cold water.
- Rinsing and soaking dishes is done cold or warm water, otherwise food particles will stick to the dishes.
- From high temperatures, hoses, gaskets quickly wear out, pipes are bent, connections are weakened.
- Frequent shutdown of hot water will not allow you to use the dishwasher regularly.
Hot water connection
Many manufacturers, focusing on consumer demand, produce machines with the ability to draw hot water from the water supply.
The benefit of a dishwasher with a hot water connection is obvious, as the reviews say - electricity costs are excluded during water heating. In addition, the process of washing dishes is noticeably accelerated, because. no time wasted on heating water. However, because of the debris in the tap hot water, filters will have to be installed.
You can also consider another option for the economical use of a dishwasher - connecting to a gas water heater. Here it becomes possible to independently regulate the temperature of the water. Dishwasher with hot water connection and standpipe possible. In this case, the advantage lies in the purity of the water, because. its quality is the same as that of a cold one; no additional filters needed. Therefore, some buyers consider the column as an opportunity to save money when using a dishwasher.
Other connection options for hot water
Some manufacturers produce dishwashers with hot and cold water connections. In this version, the device itself mixes water to the required temperature. The instructions supplied with the appliance, where there is a dishwasher connection diagram, will help you make the connection correctly. Reviews speak of the undeniable benefits of this method.
If the connection to the hot tap water is in the foreground when choosing a dishwasher, you should first familiarize yourself with technical specifications device. The manufacturer in the instructions must indicate this possibility.
Utility costs never cease to amaze. Their growth encourages users to look for opportunities to save on this expense item. Many people think that connecting a dishwasher to hot water will help save a lot on utility bills. To what extent this is a justified decision, whether it is possible to implement the connection yourself and whether it is worth doing it - we will consider in the review.
Hot water: eyeliner features
Connecting PMM to hot water has a different character than connecting to cold water. It is important to take into account a number of features:
- The dishwasher inlet hose must be designed for high temperature water.
- You need to read the instructions for the electrical appliance. It is worth finding out if such a possibility is provided by the manufacturer.
- Between the pipe and the inlet hose, it is recommended to install a flow filter to filter impurities.
On a note! Despite the fact that water from a hot pipe is supplied to us absolutely clean, it is still considered technical and may contain a lot of impurities. Installing a filter and checking it annually will help protect equipment from premature failure.
Selection of components and installation
To organize a competent connection of the machine, you will need:
- Inlet hose good quality designed for high temperatures. If the model is designed for such a connection, it may already be equipped with everything you need.
- Tee tap through which the connection is made.
- Flow filter from any manufacturer, compatible with the intake hose.
Do you need additional support in the form of special tools? To your relief, no. The hose is easily fitted by hand, and to install a tee tap, you need a maximum of a fumka tape and an adjustable wrench.
Having everything you need, you can start installation work.
- Turn off the hot water supply (DHW) so as not to get burned and avoid a flood.
- Remove the plug from the pipe outlet.
- At the end of the output - where the thread is - wind the fum tape. Roll against the thread in a thin layer.
- Now you can mount the faucet and check the connection for leaks.
- Plug one end of the tee, wind the tape on the second.
- Put on one end of the intake hose, making sure that the other end can easily reach the dishwasher body.
- When you screw on the filter, you can screw the hose to the intake valve on the PMM body.
- Open the faucet and run a short empty cycle to make sure the connections are secure and there are no leaks.
If you are wondering if your dishwasher now works without hot water, then know that it does. If the DHW is turned off, you can connect the unit to the cold water pipe and continue to operate. Moreover, experts assure that “in the cold” PMM will last much longer, and this is confirmed by user reviews.
In general, each method of water supply has its advantages and disadvantages.
Pros and cons of connecting to a hot water supply
When connecting the PMM in the classical way, the equipment works in normal mode, but in the case of hot water supply, work may be disrupted by non-standard situations.
Let's start with the good:
- The washing process requires less time, as there is no heating.
- The heating element lasts much longer, because it is practically not involved. This is a controversial proposition, but worth mentioning.
- Saving electricity. This is a 100% thesis, but do not forget that hot water is also expensive, so the cost of housing and communal services may even increase.
The advantages do not inspire confidence, especially since many of them look like outright disadvantages, which, by the way, are already numerous:
- Such a connection negatively affects the grids of flow filters so you have to change them periodically. Operation of the machine without a filter system is prohibited, otherwise the parts will become clogged with dirt and impurities.
- Too hot dishwashing liquid detrimental effect on pipes and drain hose PMM, which reduces its service life.
- Decreased dishwashing quality. Under normal conditions, rinsing does not involve heating. Otherwise, food residues may stick to the dishes, and this reduces the quality of their laundering.
With all of the above difficulties, many users have doubts about the advisability of supplying the machine to the hot water supply. If you still decide to take this action, the next part of the review will be useful to you.
Hybrid connection
There is a separate type of dishwashers, mainly from the Premium class, which require a hybrid connection to the water supply. So, there are as many as three options: only cold supply, hot and simultaneously to two pipes. Experts are sure that the third method is the most acceptable. Let's explain why.
Those who decide to double supply the PMM with water from both pipes can really save a lot by choosing the right washing modes. At the same time, the technique itself mixes both types of water in the right amount. There is only one drawback in the method - the number of communications becomes twice as large, which means that you need to leave more space in the niche for all the elements.
To summarize: the machine can only be connected to the domestic hot water supply when it is recommended by the manufacturer. If your model is not designed for this, it is unlikely that it will work out the allotted time. Successful work and long-term service to your equipment!
Middle-aged and elderly people cannot get used to bills for housing and communal services. Some are so obsessed with this issue that they are constantly looking for something else that could save 2-3 rubles. According to users distributing advice on social networks, connecting the dishwasher to hot and cold or only hot water will give significant savings. Is this really so, is it possible to connect the machine to the hot water supply on your own and is it worth it, let's figure it out.
Connection Features
Connecting a dishwasher to hot water is not the same as connecting to cold water. It is very important to remember a number of features that must be taken into account when making such a connection.
- You should take an inlet hose designed for hot water.
- Read the instructions for the dishwasher first. You need to understand whether the manufacturer allows or does not allow the connection of his product to hot water supply.
- Between the inlet hose and the outlet of the hot water pipe, install an additional flow filter that will trap the impurities contained in the hot water.
Remember! Although the service provider claims that the hot water supplied to the pipes is absolutely clean, our experience says otherwise. So it's better to play it safe and put a filter, and then check it at least once a year.
Before connecting the dishwasher to hot water, it is necessary to assemble all the components. First, we take a high-quality inlet hose that can withstand hot water. By the way, such a hose can be included with a dishwasher, especially if such a machine is designed to be connected to hot water supply. Secondly, a tee tap, with which you can organize the connection, and in the future shut off the water when the need arises. Thirdly, let's take any flow filter that fits the inlet hose and can be taken to work.
For such work, no special tools are required, the hose is quite easily screwed on by hand, but in order to securely install the tee tap on the outlet of the water pipe, you need to take a fum tape and a small adjustable wrench. So let's get started.
- We turn off the hot water so that we are not doused with boiling water.
- We remove the plug from the outlet of the water pipe.
- At the end of the pipe outlet, we wind the fumka directly onto the thread.
We wind the fumka in a small amount against the thread.
- We fasten ours and make sure the connection is tight.
- On one terminal of the tee we fasten the plug, and on the other we wind the fumka.
- On the free outlet of the tee, we fasten the end of the inlet hose, making sure that its second end normally reaches the dishwasher body.
- We fasten the flow filter to the second end of the hose, and then we fasten this entire structure to the inlet valve of the machine.
In the final, we need to open the water and check how tight the connections turned out. If everything is in order, you can test run the dishwasher connected to hot water. Strictly speaking, a dishwasher needs cold rather than hot water, so the equipment will last longer, but if you really want to connect the “home assistant” to hot water supply, you can do it. Just keep in mind that in such a connection there are pluses and minuses.
Advantages and disadvantages of such a connection
If you connect a dishwasher traditional way and you use only cold water, the machine works normally. But if we connect the dishwasher to hot water, some unforeseen situations may arise. Let's start with the advantages of connecting the machine to hot water.
- The washing process is faster as there is no need to heat the water in the tank.
- The heating element wears out more slowly, because it has to be turned on less often. This thesis is controversial, but we will still take it into account.
- Energy saving. In this case, we save on electricity, but at the same time we spend expensive hot water, so the money will come out not cheaper, but rather more expensive.
As you can see, the advantages are very, very doubtful. No effort is needed to reverse the indicated information and turn advantages into disadvantages, although the final decision is of course yours. Now about the unconditional disadvantages of connecting the machine to hot water supply.
- Hot water spoils the meshes of the flow filters, so they have to be changed often. At the same time, it is also impossible without filters, otherwise any garbage and dirt will get into the dishwasher.
- Very hot water damages the nozzles and the drain hose of the machine, which reduces the life of the dishwasher.
- Under normal conditions, during the pre-wash in the dishwasher, the dishes are rinsed with cold water, which only begins to heat up during the main wash. And imagine if the pre-rinse will take place in hot water. This will end with the fact that the remnants of buckwheat, dough and other food that does not tolerate hot water will stick to the dishes and the quality of the wash will decrease.
It will be impossible to wash anything in cold water, since the dishwasher can heat water, but cannot cool it.
After reading the above information, many begin to doubt whether it is necessary to connect your favorite "home assistant" to hot water. If you are still used to standing your ground to the end and it won’t be so easy to convince you, read the next paragraph, which may seem interesting.
About hybrid connection
Some expensive dishwashers have a so-called hybrid water connection. They can be connected in three ways: only to cold water, only to hot water, to cold and at the same time to hot water. Our experts like the last option the most, and here's why.
A user whose dishwasher is connected immediately to both cold and hot water can really save money by choosing the most preferred washing mode. The machine itself will mix hot and cold water in optimal proportions, instantly providing a mixture of water and detergent to the dishes. There is only one minus here - an abundance of hoses that need to be carefully hidden behind the body. But if it succeeds, you can enjoy using your hybrid washing machine for years without having to deal with dirty dishes!
Summing up, it should be noted that dishwashers can be connected to hot water supply only if the manufacturer allows it. If you connect a machine that is not designed for hot water, you will ruin the technique. Good luck!
