Middle-aged and elderly people cannot get used to bills for housing and utility services. Some are so obsessed with this issue that they are constantly looking for something else to save 2-3 rubles on. According to users distributing advice on social networks, connecting the dishwasher to hot and cold or only hot water will provide significant savings. Is this really true, is it possible to connect the machine to the hot water supply yourself and is it worth doing, let’s find out.
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.
Remember! Although the service provider claims that the hot water supplied to the pipes is absolutely clean, our experience tells us the opposite. So it’s better to play it safe and install a filter, and then check it at least once a year.
Before connecting the dishwasher to hot water, you need 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 a hot water supply. Secondly, a tee tap, with the help of which you can organize the connection and then turn off the water when the need arises. Thirdly, let’s take any flow filter that fits the inlet hose and we can get to work.
For such work, no special tools are required, the hose is quite easily screwed on by hand, and in order to securely install the tee tap on the outlet of the water pipe, you need to take fum tape and a small adjustable wrench. So let's get started.
We screw the foam in a small amount against the thread.
Finally, we need to open the water and check how tight the connections are. 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 the hot water supply, you can do this. Just keep in mind that there are both pros and cons to such a connection.
If you connect the dishwasher in the traditional way and use only cold water, then the machine operates in normal mode. 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.
As you can see, the advantages are very, very dubious. There is no need to make an effort to turn the information provided and turn advantages into disadvantages, although the final decision is of course yours. Now about the absolute disadvantages of connecting the machine to a hot water supply.
It will be impossible to wash anything in cold water, since the dishwasher can heat the water, but cannot cool it.
After reading the above information, many begin to doubt whether it is really necessary to connect their favorite “home assistant” to hot water. If you are still used to standing your ground to the end and it is not easy to convince you, read the next paragraph, which you may find interesting.
Some expensive dishwashers have what is called a hybrid water connection. They can be connected in three ways: only to cold water, only to hot water, to cold and simultaneously to hot water. Our experts like the last option the most and here's why.
A user whose dishwasher is connected 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 supplying a mixture of water and detergent to the dishes. There is only one drawback here - the abundance of hoses that need to be carefully hidden behind the body. But if you succeed, you can enjoy using a hybrid machine for many years without having to deal with dirty dishes!
To summarize, it should be noted that dishwashers can be connected to hot water supply only if the manufacturer allows this. If you connect a machine that is not designed for hot water, you will ruin the equipment. Good luck!
A useful appliance in the kitchen is a dishwasher. It helps to save water, valuable time that can be spent on proper rest, communication with family, and doing household chores. If the family is large and everyone loves delicious home-cooked food, by the end of the day a lot of dishes accumulate, left over from preparing and eating food.
This wonderful device will easily cope with the task of washing dishes; the quality of the wash will surprise the demanding housewife. When the machine is purchased, it needs to be installed and connected. Below is a step-by-step instruction that will tell you how to connect a dishwasher with your own hands to the water supply, cold and hot water, sewerage, electricity, how to choose the right place, how to install the equipment.
Dishwashers are gaining great popularity and are often found in apartments and houses. Washing dishes in a machine is convenient and comfortable. The device allows you to save water consumption and electricity required to heat water. It is not surprising that a dishwasher is present in many homes or is planned for the nearest purchase. The best time to decide to purchase this device is when renovating a kitchen.
If the place is determined and prepared, you can install the machine at any time. Installation work is not complicated, you can successfully complete it yourself. What is needed 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:
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.
First you need to decide on the location of the equipment. It is advisable to foresee the placement location in advance in the kitchen design, but you can easily install it at any time if the necessary networks are nearby: water supply, sewerage, electricity.
The optimal location is near the sink. Before purchasing, it is necessary to evaluate the amount of space available, because the equipment is offered in different sizes. To gain additional space, it is worth giving up one kitchen cabinet.
Freestanding models have standard widths:
The standard depth is 60 cm, height is 85 cm. In most cases, the machines are equipped with legs that allow minor adjustments (raise, lower by 2-4 cm). Some free-standing models allow installation under the kitchen countertop; their top cover can be removed. 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 installed on the kitchen table. The compact model resembles a home microwave oven in appearance and does not require much space. Compact appliances will complement a small kitchen where it is impossible to install standard-sized appliances. Compact models are purchased by residents of rented apartments, childless couples, and bachelors.
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:
Using hot water is useful if the heating element burns out; replacing this component is expensive. Unfortunately, in modern technology, spare parts do not last very 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 household appliances market. 
Before connecting to the water supply, you need to make sure that the water:
What hardness is acceptable?
When heated, compounds contained in water decompose into insoluble carbonates, forming scale (a phenomenon well known to people who use electric kettles).
Increased water hardness can:
To reduce hardness, it is necessary to install appropriate main filters at the entrance of the water supply to the apartment or directly in front of the equipment.
You can connect the water to the dishwasher yourself. Each machine is equipped with a water supply hose. Depending on the manufacturer, the lengths of the hoses are:
If the hose in the purchased model is too short, you need to purchase an extended version. It is not recommended to extend water hoses by connecting them to each other, as this may cause water leakage at the joints.
An easy way is to connect the dishwasher to the water - under the sink. Flexible high-pressure hoses that need to be hidden in the sink cabinet are suitable for these connections (the hose is included with the machine).
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 water supply system. To operate the device, it is sufficient to provide a water supply of at least 10-15 l/min; the water pressure must have the value specified by the manufacturer (range: 0.1-1 MPa).

Most dishwashers have their own hoses and tubes for draining used water. They have different lengths, but the outflow pipe, if necessary, must be lengthened while maintaining the necessary tightness.
Attention! To prevent unpleasant odors from appearing in the dishwasher, it is important to ensure that wastewater is removed at the proper slope.
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 opening directed upwards, possibly extending horizontally from the wall. The bent end of the flexible drainage hose, which is usually equipped with the machine, must be placed in the drain pipe and secured to the wall with a special handle so that it does not fall out.

You can use a special rubber plug with a hole for the hose or a plastic sewer connection with a 1/2-inch connection to attach the drain hose.
If there is no drain to which the dishwasher can be connected directly, you can use a sink trap. You will need to replace the top fitting of the siphon with a tee for connection with a side connection. The design of some siphons includes a tee fitting for installing 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.

All devices available on the market operate at a nominal voltage of 220 V and have an electrical cable with a plug.
Important! The outlet must be grounded.
It is worth noting that for safety reasons this should not be done when connecting to the mains. Dishwashers are equipped with a system that interrupts the water supply when malfunctions or internal leaks occur.
What not to do!
Using the above rules, you can easily connect the dishwasher to the networks with your own hands. You will need a little skill, basic tools, a tee, a faucet. Installing a 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.
How to properly connect a dishwasher to hot water? Most models are designed to be connected to a cold water supply, so check the instructions first. It will indicate how and in what sequence to act. According to consumer reviews, by connecting equipment to a hot spring, you can save on electricity consumption. Is it so? We'll look into it in the article.
Depending on the brand of your dishwasher, the instructions indicate degrees for correct connection. Does the appliance work without hot water? For example, for Bosch models no more than +20 degrees is provided. This means that connection to a hot water supply is not possible. Otherwise, your warranty may be voided.
Do you 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 supply?
Remember! The dishwasher can heat the water, but not cool it.
Keep in mind that hot water has higher pressure than cold water. With a conventional mixer, the high-pressure flow will flow through the low-pressure flow pipe. Therefore, you will have to install a special mixer that will block one channel.
Collect all the necessary tools and parts for convenient work:
Doing the work yourself:
Carefully seal all connections with fum tape, wind it against the thread at least 10-15 times. Now open the water supply and check that the connections are correct. Is nothing leaking? Feel free to test run the PMM.
In more expensive dishwasher models, it is possible to connect to water in three ways:
The latter option is a success. The equipment independently mixes the streams, bringing the water to the desired temperature. You really save on electricity; you can choose the dishwashing mode yourself.
The hybrid connection requires a large number of hoses, which is not always convenient or aesthetically pleasing. But if you find a way to connect everything neatly, then you can use the machine to your satisfaction.
Think twice before connecting the dishwasher according to the instructions. This can damage not only the dishes, but also equipment in general.
Prices for utilities never cease 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.
Connecting a PMM to hot water has a different character than connecting to cold water. It is important to consider a number of features:
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 your equipment from premature breakdown.
To organize proper connection of the machine you will need:
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 an adjustable wrench.
Having everything you need, you can begin installation work.
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 cold water pipe 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.
When connecting the PMM in the classical way, the equipment operates in normal mode, but in the case of hot water supply, operation may be disrupted by non-standard situations.
Let's start with the good:
The advantages do not inspire confidence, especially since many of them look like outright disadvantages, of which, by the way, there are already many:
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.
There is a separate type of 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 in the required 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. Successful work and long service life for your equipment!
