How to properly connect the dishwasher to hot water? Most models are designed to be connected to a cold water supply, so first of all, look at the instructions. It will indicate how and in what sequence to act. According to consumer reviews, by connecting appliances to a hot spring, you can save on electricity consumption. Is it so? Let's find out in the article.
Do I need hot water to connect PMM
Depending on the brand of your dishwasher, the instructions indicate the degrees for the correct connection. Does the appliance work without hot water? For example, for Bosch models, no more than +20 degrees is provided. This means that it is not possible to connect to a hot water supply. Otherwise, you may void your warranty.
Think you can save money by using high temperature water? After all, then the heater will not work, this will reduce electricity bills. Why do manufacturers recommend using cold water?
- The permissible rate of heating water for a dishwasher is 60 degrees. Using a source with an elevated temperature will damage the filtration systems.
- Hot water releases more debris than cold water. You will need to install an additional cleaning filter.
- Hoses quickly deteriorate, gaskets wear out. When exposed to high temperatures, hoses and pipes can be bent, connections can loosen.
- Decreased quality of dishwashing. Pre-rinsing of food residues is always done with cold water. Otherwise, food pieces and particles will stick to the plates.
Remember! A dishwasher can heat water, but it can't cool it.
Keep in mind that hot water has a higher pressure than cold water. With a conventional mixer, the high pressure flow will go through the low flow pipe. Therefore, you will have to install a special mixer that will block one channel.
Connection steps
Gather all the necessary tools and parts for convenient work:
- intake hose that can withstand high temperatures (if your model is designed for such a connection, then the hose is included);
- brass tee with stopcock;
- special mixer;
- cleaning filter;
- wrench;
- fum-tape for sealing.
Doing the work yourself:
- Shut off the water supply.
- Prepare the outlet of the water pipe.
- Install a brass tee on the pipe outlet.
- Connect the intake hose to the tee.
- Attach the filter to the free end of the hose.
- Connect the structure to the dishwasher.
Carefully seal all connections with fum-tape, wind it against the thread at least 10-15 times. Now open the water supply and check if the connections are correct. Nothing is leaking? Feel free to test launch PMM.
Other connection options
In more expensive models of dishwashers, it is possible to connect to the water in three ways:
- to cold;
- to hot;
- to both sources at once.
The last option is successful. The technique independently mixes the flows, bringing the water to the desired temperature. You really save on electricity, you can choose the mode of washing dishes yourself.
Hybrid connection provides a large number of hoses, which is not always convenient and aesthetically pleasing. But if you find a way to connect everything neatly, then you can use the machine to your heart's content.
Think a few times before you connect the dishwasher not according to the instructions. This can damage not only the dishes, but also the equipment as a whole.
All modern washing machines have a heating element for heating water. But some users, in order to save money, decide to connect the machine directly to a hot water pipe, while dreaming of saving on a communal apartment.
How justified is this decision and when connecting to a hot pipe is really rational, you will learn from this article. We will consider whether it is possible to connect the washing machine to hot water, we will describe what is needed for this and how to do the work with our own hands.
Worth it or not
The manufacturer usually provides for connection exclusively to cold water. But there are models in which the possibility of a double connection is realized - both to a cold pipe and to a hot one.
If you have an ordinary machine, and you do not know what water to connect it to, then you should know that it is better not to violate the manufacturer's instructions. If the instructions indicate that the connection is only to cold, do so. Otherwise, the following consequences are possible:
There are also advantages of such a connection, for which, in fact, some advanced users choose it. You can save on electricity - that's a fact. But, given that the cost of hot water is not much lower than the price of energy resources, benefits are highly questionable..
What you need to connect the machine
If you have a machine without hot water or a model that connects to both hot and cold water, further instructions will be useful to you. In the design of such an SMA, there are two inlet hoses at once, so the connection will differ from the standard one. Read how to connect such a machine below.
Let's start with the toolkit. You will need:
- wrench;
- ¾ inch spacer rings (silicone or rubber);
- 2 main tee taps for ¾ with a side outlet to the water intake hose;
If the tee faucet is installed in a conspicuous place, for example, in the bathroom on the faucet, then choose beautiful chrome options. For hidden, any cranes are suitable.
- ¾ adapters;
- flow filters ¾.
Important! Use a wrench carefully to avoid damaging the chrome faucet nuts. If you are afraid to ruin the coating, cover the elements with electrical tape so as not to scratch the chrome parts.
How to connect
There are several connection options: simple - to the mixer (here you will figure it out on your own) - and more complex, but reliable. Let's stop on it.
Many people are tempted to connect the washing machine to hot water. For what? For example, to save energy on heating water and reduce washing time. In this article, we will determine all the pros and cons of such a “hot” approach to connecting a washing machine 🙂
And the idea to write an explanatory article on this topic came to us after receiving a letter from a resident of Kyiv to our mailbox ...
Andrei is 24 years old, he is a native of Kiev, an aspiring businessman, a talented programmer. For six months now he has been dating Katya, a young student at the Kyiv University of Tourism, Economics and Law. A couple of days ago, we received a letter where the newlyweds described the whole situation and asked for a competent answer regarding the following problem.
And here's the thing. A few weeks ago, Katya and Andrey started renting a one-room apartment in Troyeshchina. Everything would be fine - and the apartment is good, spacious, and all household appliances are available, and a huge loggia. The washing machine, although old, was brought from Germany and is of good quality. But the problem was that the washing machine was connected to hot water.
According to Andrey, Google helped to find the service center. Since the newlyweds lived in Troyeschina, they entered the phrase into the search. And on the first page of the search was the site of the company "5 stars service", which attracted attention.
Andrey and Katya write:
“After we saw that the washing machine was connected to hot water, we were initially delighted.After all, in addition to the monthly payment to the owners, our shoulders were the monthly payment for electricity by the meter. The thought immediately came to mind that it would turn out to be a good idea to save on electricity, because hot water is immediately supplied to the tank and the washing machine does not need to spend electricity on heating. But immediately after the first wash, the joy disappeared and doubts arose. The fact is that the laundry began to wash much worse, and in some places even stains remained ... And this is after washing on the longest program!
At the time of writing this article, another person called our service center with a similar question, which sounded like this:
“What bad can happen if the automatic machine is connected immediately to hot water? There, the temperature is about 50-60 degrees - just right for washing clothes. And the heating element will not deteriorate, as I understand it, because it will almost never turn on - the water is already hot! But no one has seen such a connection to hot water, and this gives me reason to doubt the correctness of my conclusions.
Yes, indeed, not everything is so smooth in the matter of connecting the washing machine to hot water. So, washing machine and hot water from the water supply - is it possible, are these two concepts compatible?
There are (albeit in small numbers) models of washing machines that are designed to be connected to both cold and hot water at the same time. Those. The washing machine has 2 hoses. Recently, manufacturers of washing machines have begun to move away from this practice, especially in our country and other post-Soviet countries. This is mainly due to the poor quality of the incoming hot water.
In addition, hot tap water carries a lot of impurities, which make it necessary to clean the inlet filter of the washing machine more often. Plus, hot water tends to be harder, which results in more wastage of laundry detergent.
Many washing powders are designed for gradual heating of water, so a sharp ingress of powder into a hot environment will prevent many bioadditives from performing their function. The quality of washing, of course, falls.
Cons of connecting to hot water:
- The quality of washing noticeably drops, the dirt “brews”, strongly sticks to the fibers of the fabric, and then even for the entire washing cycle it may not be completely washed off. This is perhaps the most important disadvantage.
- The powder is not completely washed out of clothes when rinsing with hot water. Want to wear clothes soaked in laundry detergent and get a skin disease?
- After rinsing with cold water, the laundry smells better than after rinsing with hot, and things do not become gray and washed out.
- Hot water in our country is often turned off and washing will not work if necessary 🙂
- The time savings will still remain minimal, since the heating element (heating element) heats the water for 15-30 minutes.
Advantages of connecting to hot water:
- Getting rid of scale on the heating element of the washing machine. It seems like a huge plus. But do not be so afraid of scale, because there are proven ones. By the way, you can read about scale and general care of the washing machine at the link.
- Yes, connecting your washing machine to hot water saves energy. But how much? Answer and calculations below.
Let's say you don't have water meters. Then we calculate the electricity consumed by the washing machine for one wash. For one wash, the washing machine consumes an average of about 2 kW of electricity. For Kyiv, this is equivalent to 24.36 kopecks per 1 kW (tariffs for 2011), i.e. 50 kopecks per kW. If you refuse to heat the water and the electricity will be spent only on the operation of the electric motor, then the savings will be about half. Those. near 25 kopecks is the whole price of the issue. Scanty savings, given all the disadvantages and risks of connecting a washing machine to hot water. It's worth it?
It's stupid to pay hundreds of bucks and do the laundry, rinse your hands, walk around in poorly rinsed underwear, which, moreover, does not smell fresh. After all, this is not what you bought a washing machine for.
Even if a washing machine consumes a lot of electricity to heat water, saving your own time and energy is more important. Calculate the cost of an hour of your working time and you will immediately understand that it is unprofitable to interfere with the operation of automation!
So if your washing machine is connected to hot water, then it is strongly recommended to abandon this stupid idea and to the water supply and be sure to use quality materials. Trust the professionals and call us right now by phone in Kyiv 383 90 60 and order the reconnection of the washing machine to cold water. Improve the quality of washing clothes, and with it the quality of your life today!

No one is really able to answer whether it is possible to connect the washing machine to the water supply to the hot riser. There are no statistical data, no information about the modes of operation of the input filters. Adding to the difficulty is the inability to find a washing machine specifically designed for the purpose of using hot water.
Washing machines for hot water connection
So, the ability to connect to hot water is not considered an option for washing machines, according to Yandex Market filters. Popular rumor says that there are such models. There are even disputes whether the devices prevail abroad or are made exclusively for Russia. It has been noticed that boilers are often used in the USA, private houses occupy quarters and it is unprofitable to run a pipeline. As a result, they are fed with gas or liquid fuel, considerable savings are obtained. From the described considerations, washing machines are made with the ability to connect to hot water. Instead of wasting extra electricity, a ready-made temperature is taken.
The advantage of the approach under the described conditions is obvious, it is more difficult when the supply is network. The chemical composition of hot water is fundamentally different, salts are added there to get rid of scale, therefore, for other reasons, drinking from a hot riser is prohibited. For example, in Norway, some people brew coffee in a similar way, in the Russian Federation this approach will end sadly. When the topic of connecting the washing machine to the water supply comes up, the turn of doubts comes. It all starts with the intake valve.
They saw a video on YouTube where a gander is twisted out of the mixer, then the inlet hose of the washing machine is docked. Explained like this:
- It is no longer necessary to heat water for modes, energy is saved, the likelihood of burning wiring or flying out of traffic jams is reduced. It is logical: the heating element consumes 1.5 kW or more. This is a powerful load on the network, if an electric kettle and a microwave oven are already working in the house, the switchboard limit is indeed exceeded, leading to traffic jams.
- The second argument: "everything is well rinsed in hot water." The steps of the cycle are carried out at an elevated temperature, which is supposedly good. Removes the smell of washing powder, which causes allergic reactions, irritation of the upper and lower respiratory tract. According to unverified reports, connecting the washing machine to the water supply through a hot riser will have a beneficial effect on the health of the owner and family.
- The third point is controversial in the opinion of the authors. It is said that it is possible to take water, for example, from a boiler, set the desired temperature, even boil it.
- A washing machine connected to a hot riser will definitely not break.
Doubts remain. The question arises why manufacturers of washing machines do not write that it is allowed to connect to a cold and hot riser if there is no difference. Likely answers:
Is it worth it to connect the washing machine to a hot riser
Given the above, it seems risky to conduct such experiments. The video shows that the hose suffers a sharp bend in the region of one nut. It is not a fact that the rubber is designed for such an effort, and the flood in the bathroom is formed quickly, and will not stop when the washing machine finishes working with an error code.
As a result, it is good for allergy sufferers to connect the washing machine to the water supply through a hot riser, only if the owner is able to assess the upcoming dangers and consequences. As far as energy and time savings are concerned, they are not so great. Think about it - the washing machine is constantly running and rarely just stands and heats the water. The cycle as a result will be reduced by only 2-3 minutes.
Are washing machines designed to connect to hot water
Dishwashers of the specified type are available, but it is difficult to find laundry. Let's look at E96.ru and e-catalog to save readers' time. As you might expect, there is no information anywhere on choosing a washing machine for connecting to a hot riser. It's like they don't exist in nature. We searched Yandex and found the link http://www.techport.ru/katalog/products/striralnye-mashiny/tag/s-podklyucheniem-k-goryachej-vode. You see - connecting the washing machine to the water supply through a hot riser is quite real. True, both risers are used, and the desired temperature is dialed from the needs automatically, according to the program. The described washing machine can be connected! Additional source on the topic http://otvet.mail.ru/question/69990595.
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 the dishwasher directly to hot water. After all, the tariff for electricity increases almost daily, and hot water is constantly available 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.
Hot water brings in more debris, 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 load. 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 comes in at a temperature of 60 degrees, 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 only cold water should be used.
- 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.
- The plug must be removed from the water pipe.
- 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. Proper 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.
