Dishwashers, even with A+++ efficiency, spend a certain amount of electricity heating water. This raises a legitimate question for the buyer: can the dishwasher be connected to hot water and not spend money on electricity? Let's try to figure it out.
Specifications
According to the technical specifications, dishwashing equipment generally operates with water not hot at 60°C, and units from Bosch do not exceed 20°C. This means that the pledge is exceeded temperature regime will definitely lead to a quick breakdown and loss of warranty repair.
Causes of malfunctions:
- High water temperature leads to failure of the filtration system.
- Tap hot water is more contaminated than cold water.
- Rinse and soak dishes using cold or warm water, otherwise food particles will stick to the dishes.
- From high temperature Hoses and gaskets quickly wear out, pipes become bent, and connections become loose.
- Frequent shutdowns of hot water will prevent you from using the dishwasher regularly.
Hot water connection
Many manufacturers, focusing on consumer demand, produce machines with the ability to draw hot water from a water supply.
The benefits of a dishwasher with a hot water connection are obvious, as reviews say - the cost of electricity when heating water is eliminated. In addition, the process of washing dishes is noticeably accelerated, because... No time is wasted heating water. However, due to debris in tap hot water, you will have to install filters.
You can also consider another option for economical use of a dishwasher - connecting to a gas water heater. Here you can independently regulate the water temperature. A dishwasher with hot water and water heater connections is possible. In this case, the advantage lies in the purity of the water, because... its quality is the same as that of cold, i.e. no need to install additional filters. Therefore, some buyers consider the column as an opportunity to save money when using a dishwasher.
Other hot water connection options
Some manufacturers produce dishwashers with hot and cold connections. cold water. In this version, the device itself mixes the water until required temperature. The instructions included with the equipment, which contains a wiring diagram for the dishwasher, will help you make the connection correctly. Reviews speak of the undeniable benefits of this method.
If connected to a hot tap water is in the foreground when choosing a dishwasher, you should first familiarize yourself with technical characteristics apparatus. The manufacturer must indicate this possibility in the instructions.
Theoretically, you can connect the washing machine to hot water. But is your goal to wash clothes or save on cold water and electricity? For some types of laundry fabrics that will be rinsed in hot water, this is unfavorable. For synthetics, you can rinse in hot water.
The most breakable parts and components in washing machines are usually shock absorbers and bearings. Shock absorbers fail faster if you overload the machine. Willingly or not, washing a blanket or jacket, a heavy cape. Water hardness and temperature do not affect the performance of shock absorbers and bearings. When washing woolen products, you need to sprinkle or pour a little liquid powder because... Wool foams up detergents a lot. But thanks to hot water and detergents, powders or gels, a lot of foam is formed, which can throw foam where it doesn’t need to go and damage the washing machine. In fact, how will scale disable the washing machine? Only heating element! But because There is no need to heat the water and the heating element is essentially not needed. The answer is that you can wash in hot water, and you can also connect the washing machine to hot water, provided that the hoses connected to the washing machine are designed for hot water. The rubber of the hoses can quickly deteriorate due to the high temperature of hot water. The washing machine itself will do nothing from the hot water. The washing machine itself is designed to heat water up to 90 degrees. And if you use modern washing powders, gels that make the water softer and prevent plaque from forming as intensely as if you washed without special high-quality detergents. Plaque will form in any case, both from cold water and from hot water, from any water except highly purified water. Suppose if you use highly purified water for washing, plaque will still form. Plaque will not form as much as from dirty or hard water from the plumbing system. Thanks to the dirty laundry that the machine washes. What is dirt made of? From earth, sand, clay, ash, pieces of skin, food...
and this whole periodic table is not complete, of course.
Also by washing only hot water may occur in the washing machine bad smell. The laundry may also smell unpleasant. Because washing machine It will remain warm after washing. In a warm environment, bacteria grow faster. The water in the drum becomes sour when the machine is standing even with the door open. In fact, there is no savings if you have to rinse the laundry after washing. When washing only with hot water, a residue in the form of dirt will lag behind in the tank and the water will constantly become dirty, even when rinsing, there may be dirt on your laundry after washing. It will be clearly visible on black, dark underwear.
Prices for public utilities never ceases to amaze. Their growth encourages users to look for opportunities to save on this expense item. Many believe that connecting a dishwasher to hot water will help significantly save on utility bills. How justified this decision is, whether it is possible to implement the connection yourself and whether it is worth doing - we will consider in the review.
Hot water: features of eyeliner
Connecting a PMM to hot water has a different character than connecting to cold water. It is important to consider a number of features:
- The dishwasher intake hose must be designed for high-temperature water.
- You need to study the instructions for the electrical appliance. It is worth finding out whether the manufacturer provides such a possibility.
- It is recommended to install a flow filter between the pipe and the inlet hose to filter out impurities.
Note! Even though the water is from hot pipe served to us absolutely pure, it is still considered technical and may contain a lot of impurities. Installing a filter and checking it annually will help protect your equipment from premature breakdown.
Selection of components and installation
To organize proper 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 necessary.
- The tee tap through which the connection is made.
- Flow-through 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 inserted by hand, and to install the tee tap you only need a “fumka” tape and adjustable wrench.
Having everything you need, you can begin installation work.
- Shut off the hot water supply (DHW) to avoid getting burned and avoid a flood.
- Remove the plug from the pipe outlet.
- At the end of the output - where the thread is - wind fum tape. Twist against the thread in a thin layer.
- Now you can mount the tap and check the connection for leaks.
- Plug one terminal of the tee and wind tape around the second.
- Place one end of the intake hose, making sure that the other can easily reach the dishwasher body.
- Once you have screwed on the filter, you can screw the hose to the intake valve on the PMM body.
- Open the tap and run a short idle cycle to make sure the connections are secure and there are no leaks.
If you're wondering if your dishwasher now runs without hot water, it does. If the DHW is turned off, you can connect the unit to a pipe with cold water and continue operation. Moreover, experts assure that “in the cold” the PMM will last much longer, and this is confirmed by user reviews.
In general, each water supply method has its own advantages and disadvantages.
Pros and cons of connecting to DHW
When connecting PMM in the classic way the equipment operates as normal, but in the case of hot water supply, operation may be disrupted by non-standard situations.
Let's start with the good:
- The washing process requires less time, since there is no heating.
- The heating element lasts much longer because it is practically not used. This is a controversial proposition, but it is worth mentioning.
- Saving electricity. This is a 100% thesis, but do not forget that hot water is also not cheap, so the cost of paying for housing and communal services may even increase.
The advantages do not inspire confidence, especially since many of them look like outright disadvantages, of which, by the way, there are already many:
- This connection negatively affects the meshes of flow filters, so you will have to change them periodically. Operating the machine without a filtration system is prohibited, otherwise the parts will become clogged with dirt and impurities.
- Dishwashing liquid that is too hot has a detrimental effect on the pipes and drain hose PMM, which reduces its service life.
- The quality of dishwashing decreases. Under normal conditions, rinsing does not involve heating. Otherwise, food residues may stick to the dishes, and this reduces the quality of their washing.
With all the above difficulties, many users have doubts about the advisability of connecting the machine to the hot water supply. If you decide to take this action, the next part of the review will be useful to you.
Hybrid connection
Exists separate species dishwashers, mainly from the Premium class, which require a hybrid connection to the water supply. So, there are three options: only cold supply, hot supply and simultaneously to two pipes. Experts are confident 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 appropriate washing modes. In this case, the equipment itself mixes both types of water into the right quantity. There is only one drawback in this 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 be connected to the domestic hot water supply only when recommended by the manufacturer. If your model is not designed for this, it is unlikely to last the allotted time. Good luck with your work And long service your technology!
Modern dishwashers make work easier and save time, our main resource. The only big disadvantage is the energy consumption when heating water for washing dishes. Electricity today is not cheap, and a reasonable question arises - what if you don’t heat the water in the dishwasher, but supply it with hot water? Is this possible, and how will it affect the operation of the machine? All the pros and cons of such a connection will be covered in the article.
The traditional way to connect water to the device
Most dishwashers in the world are designed to be connected to a cold water supply system, so this connection method is considered traditional. The operating instructions for the device usually outline the connection process step by step.
Probability of hot water supply to the dishwasher
The possibility of connection depends directly on the brand of dishwasher - not all models can be connected to hot water supply. When connecting, you must use a hose designed for hot water. It is usually marked with a red stripe. And it’s not even a matter of markings - they are used for different hoses various materials that meet certain requirements.
The nuances of connecting hot water to the dishwasher
How to find out if hot water can be supplied to the appliance
Before connecting the PMM to a hot water supply, you need to make sure that this option is possible - its permissibility should be written in the operating instructions for the device. Some models also have a hybrid connection option - from two hoses at once.
Required tools and materials
To work you will need:
- high temperature water hose;
- brass tee (not silumin) with valve;
- filter rough cleaning water;
- adjustable wrench, pliers, Teflon tape.
Connection procedure sequence
The connection is made in the following order:
Safety conditions
It should be remembered that in the hot water supply system there is always high blood pressure. Under no circumstances should you skimp on the hose - this can lead to early failure. When connecting, follow the instructions and carefully seal the connections using Teflon tape. Before putting the device into operation, be sure to perform a test run and make sure there are no leaks.
Pros and cons of connecting a dishwasher to hot water
A question of saving
Will you be able to save money? Difficult question, and here's why:
The only advantage is the reduction in energy costs for heating water.
Extending the life of the device
As described above, in order for the dishwasher to last its warranty period, it must not be used in abnormal modes. If it fails and the hot water supply system is used, the warranty may be voided. Ultimately, consuming one and a half kilowatts when heating can be much cheaper.
In addition, when cold water is connected, it is diluted with special salt from the ion exchanger for greater softness. If the temperature regime is violated, the regulation system quickly fails.
Influence on the dishwashing process
The quality of washing dishes does not change much, because the dishwasher has a thermostat that heats the water to a certain level. operating temperature. Unless the speed of the process increases due to the fact that there is no need for heating. Whether such a connection to a dishwasher makes sense is a moot point.
Relatively recently, dishwashers appeared in the homes of our compatriots. This device is appreciated not only by women, but also by men, because they have a lot of free time.
But even today, many people have many questions on various topics related to dishwashers. Common questions include questions about. Information on the correct installation of the device to the water supply system is also urgently needed. Many people believe that it is better to connect the dishwasher directly to hot water. After all, the electricity tariff increases almost every day, but there is always hot water in the tap. Why use electricity to heat water for your dishwasher?
Many experts answer the question ambiguously: “Is it possible to quickly and reliably connect a 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. But all users must strictly follow the recommendations and rules specified in the instructions for the device.
If you decide to connect your dishwasher directly to hot water, you should prepare a special fill hose. If a regular hose is installed, this can lead to serious consequences.
Please note that all water supply hoses must be marked red and blue. This way the consumer can recognize the values at any time.
Advantages of connecting a dishwasher to hot water
Many experts agree with the opinion of thrifty consumers. Therefore, they cite their advantages of connecting the dishwasher to warm water.
This connection method significantly reduces energy consumption in the house. After all, the device washes cutlery at high temperatures. The same thermal water The dishes are also rinsed for the final time, which has a beneficial effect on drying them.
The washing process is much faster, because no time is wasted 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. That's right.
Disadvantages of connecting a dishwasher to hot water
Many experts recommend paying attention to the water temperature. If it exceeds 60 0 C, this may adversely affect the built-in filtration system. All damaged flow filter meshes will quickly fail, which means they will need to be changed regularly. But you cannot use the device without filters, because debris will end up in the dishwasher.
Hot water pressure is different from cold water. The difference between these indicators increases significantly if we consider that hot water enters the device through a cylinder in the boiler.
Hot water carries more debris, so additional filters should be used.
Kinks and kinks are more likely to appear on water hoses designed for high-temperature water. Therefore, before installation, you should check whether the hose is under any physical activity. In this case, the hose may soften and rupture when water passes through it.
High temperature water also negatively affects the drain hose and pipes of the machine. This reduces its service life.
Sometimes hot water can “stick” food to the surface of the plate during the first wash. And this will significantly complicate the process of cleaning dishes.
Everyone knows that problems with hot water supply occur much more often than with cold water. Suffice it to remember the summer (the time of repair and maintenance work), when the period of shutting off hot water can be very long.
Often in dishwashers The washing cycle takes place at a temperature of 50 0 C. If water arrives 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 the water.
Features of connecting to hot water
The device is connected to hot water according to the same principle as to cold water. But such installation requires a number of features. So, how to properly connect a dishwasher to the water supply?
- Read the instructions for the device carefully. Make sure that the device is connected to hot water supply. After all, for example, for Bosh models, the water temperature should not exceed 20 0 C, which means you need to use only cold water.
- Prepare a special inlet hose designed for hot water.
- Install the in-line filter. It will additionally protect the dishwasher from hot water impurities. Install it between the pipe outlet and the inlet hose.
Before you begin connecting the device, you should assemble all the components. The hot water inlet hose must be of high quality. Some manufacturers supply a similar hose with a dishwasher designed for such a connection.
Prepare a tee valve. It must be used to connect the machine. In addition, it will help shut off the water supply if necessary.
So, you need to prepare:
- hose;
- cleaning filter;
- special mixer;
- brass tee with shut-off valve;
- fum tape and wrench.
Connecting the dishwasher to hot water
To supply hot water to the dishwasher, you do not need to use special tools. using only hand strength. Well, for reliable installation tee tap, you should use an adjustable wrench. Remember that the fum tape must be wound in the direction against the thread. It is necessary to make about 10 revolutions.
So, the connection sequence is:
- We remember about safety, so we turn off the water. Otherwise, you may be scalded by boiling water.
- WITH water pipe the plug must be removed.
- There is a thread at the end of the pipe outlet. Do not wrap fum tape or tow on it.
- Screw on the brass tee. We check whether the joints are tightly connected.
- We screw a fum tape onto one terminal of the tee and screw the end tightly inlet hose. We check that it can easily reach the device body.
- We install a plug on the second terminal of the tee.
- And install the flow filter at the other end of the hose
- We attach this entire structure to the filling valve of the device.
Upon completion of all work, you should open 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 dishwashers, it is possible to connect the device to water in 3 ways:
- to hot;
- to cold;
- simultaneously to 2 sources.
It is the latter method that is especially popular. Thanks to it, equipment can independently mix 2 streams of water to the required temperature. This way you can not only save energy, but also choose desired mode sinks
But this method involves using large quantity 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 stated in the instructions for the device, which indicates a clear sequence for installing kitchen equipment.
- Turn off the water supply tap;
- Use a wrench to unscrew the mixer nut and release the thread of the pipe.
- 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.
- We install the mixer.
- Turn the tap on the tee to the “closed” position. We open the general water supply and check the tightness of the joints.
- Install the dishwasher hose by screwing on the plastic nut
Conclusion
A dishwasher is an indispensable device in every modern house. Correct installation guarantees long-term operation of the device. Should I connect the device to hot water? A definite 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 several times before installing the device without paying attention to the recommendations specified in the instructions. This can harm not only the dishes, but also the equipment.
So, which water is better to connect the dishwasher to (cold or hot) is up to the owner of the device to decide. Everything depends only 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 consider the possibility probable breakdowns device and inconvenience in its operation.
