The rise in electricity prices is forcing other homeowners to look for ways to save money. Many of them reason quite reasonably: there is no need to waste time and additional kilowatts for the dishwasher to heat the water - it can be immediately connected to the hot water supply. All the features of such a connection are in our article.

Dishwasher requirements

First of all, you should familiarize yourself with the instructions of the unit and understand whether it is possible to connect the machine to hot water or it is better not to do this. For example, there are dishwashers that can only work with water with a temperature of +20 degrees . Such models are produced by the well-known manufacturer Bosch. It is not straightforward to connect them to a centralized hot water supply system. Usually, dishwasher manufacturers inform consumers about the possibility of connecting the units in non-traditional ways.

Having chosen the appropriate version of the unit, first of all, purchase a special filling hose (the usual one will not work) . It must withstand intense stress from exposure to high temperatures. All connection hoses are marked and color-coded.

As with cranes, they come with an identification blue or red. Individual dishwasher manufacturers directly complete the assembly with a red hose. In case of absence, this element must be purchased.

Besides, ask about the flow-through filter - this is protection against impurities . The mesh structure of the filter does not allow solid impurities and dirt to penetrate into the mechanisms of the device. And in order, if necessary, to be able to urgently stop the water supply, connect the dishwasher through a tee tap.

If there is one in the device, it's also good, but experts recommend using a tee made of brass, which comes with a shut-off valve . Therefore, it would be better to buy a brass locking mechanism.

Having collected all the necessary components, do not forget to stock up on some more fum tape, as well as a small adjustable wrench.

You won't need a large set of tools, and all the work is easy to do with your own hands . After preparation, proceed to connect the dishwasher to the hot water pipe.

Connection rules

It is entirely up to you to connect the dishwasher to hot water or install it in the traditional way. But if you want to try, then during the installation process, you must follow a number of rules:

• before starting work, turn off the hot water supply so as not to scald with boiling water;
• then remove the plug from the outlet of the water pipe;
• wind the fumka at the end of the pipe outlet against the thread (while doing this, make 7-10 turns with the fum tape);
• screw on the tap for connecting the dishwasher;
• make sure the connection is tight;
• screw the inlet hose onto the tee tap (its length should correspond to the distance to the machine body);
• connect the flow hose through the filter to the dishwasher inlet valve;
• open the water and check the performance of the structure for leaks;
• when you are convinced that everything is done efficiently, the tightness is ensured, start a test wash.

The dishwasher requires more cold water to start - this way it lasts longer . But when you really want to save on water heating or experiment, you can connect it directly to the hot water supply (if you have a centralized system).

However, it should be understood that such a connection has both advantages and disadvantages. Let's take a closer look at this information.

Pros and cons

The usual mode of operation for dishwashers is to start running cold water and then heat it up by the device itself. But those who are not satisfied with the traditional connection to the blue faucet should be aware of the negative aspects.

• The meshes of the flow-through filter are very often clogged, they need to be changed every time. Without a filter, the dishwasher will become clogged with dirt, as a result of which it will quickly fail.
• Washing quality is not always perfect. With the recommended connection, the dishes are pre-soaked in the rinse mode with cold water, the water is heated in the main wash mode, so the dishes are cleaned gradually. And when hot water is exposed to food residues, the remnants of dough, cereals and other products can stick to the dishes. As a result, the dishes may not wash as cleanly as expected.
• And it's not hard to guess why experts warn that when connected to hot water, the dishwasher will last less. The fact is that from constant exposure to only hot water, components (pipes, drain filter and hose, other parts) fail faster, which reduces the operational life of the product as a whole.
• In addition, with such a connection, it will no longer be possible to wash anything with cold water: the dishwasher will not be able to cool the water. It should also be said that the pressure in the red tap is not always stable, and this can cause malfunctions in the operation of the unit and lead to serious consequences for equipment.

If you nevertheless decide to finally connect your kitchen "helper" directly to hot water, you will get some advantages. Let's list them

• Save time waiting for clean dishes. The unit will not waste extra minutes heating the water, so it will wash the kitchen utensils much faster.
• Save energy with shorter wash times and no hot water operation. But it should be borne in mind that hot water is more expensive than cold water, and this will also have to be paid.
• It is possible to keep the dishwasher heating element intact.

Many people believe that all the advantages of connecting dishwashers to hot water are not worth half the disadvantages, that is, there is no point in doing this. Who will need, for example, a heating element if the other mechanisms fail?

In a word, each user will have to solve this issue independently . True, as it turned out, it is possible to make a hybrid connection - to two sources at once: cold and hot. This method is quite popular, but not suitable for all premises.
