Is it possible to connect the dishwasher to hot water

Modern dishwashers make work easier and save time, our main resource. The only big minus is the energy consumption when heating water for washing dishes. Electricity is not cheap today, and a reasonable question arises - what if you don’t heat the water in the dishwasher, but apply hot water to it? Is this possible, and how will it affect the operation of the machine? The pros and cons of such a connection will be covered in the article.

The traditional way to connect water to the device

Most of the dishwashers in the world are designed to connect to a cold water supply system, so this connection method is considered traditional. Instructions for use usually describe the connection process step by step.

The likelihood of a hot water dishwasher

The possibility of connection depends directly on the brand of the dishwasher - not all models can be connected to hot water. When connecting, use a hose designed for hot water. It is usually marked with a red stripe. And it’s not even a matter of marking - different materials are used for different hoses 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 device

Before connecting the PMM to the hot water supply, you need to make sure of the possibility of this option - its validity should be written in the instruction manual of the device. Some models also have a hybrid connection option - from two hoses at once.

Necessary tools and materials

For work you will need:

  • high temperature water hose;
  • brass tee (not silumin) with valve;
  • coarse water filter;
  • adjustable wrench, pliers, teflon tape.

Connection Procedure

Connection is made in the following order:

  • shut off water supply;
  • prepare the outlet of the water pipe;
  • connect a tee to the pipe outlet;
  • connect the water intake hose to the tee;
  • attach a coarse filter to the free end of the hose;
  • connect the dishwasher to the water supply system.

Safety conditions

It should be remembered that in a hot water supply system there is always high pressure. In no case should you save on a hose - this is fraught with quick damage. When connecting, follow the instructions, carefully seal the joints with Teflon tape. Before putting the device into operation, be sure to carry out a test run and make sure there are no leaks.

Attention! Never use an ungrounded dishwasher! Possible electric shock.

Pros and cons of connecting a dishwasher to hot water

The issue of saving

Will it save? This is a tough question, and here's why:

  • The permissible operating temperature at the dishwasher does not exceed 70 degrees, if it is exceeded, filtration systems may fail.
  • A coarse filter is definitely needed - there is a lot of dirt and debris in the hot water supply system.
  • Quick failure of hoses and gaskets due to high temperatures.

The only plus is the reduction of energy consumption for heating water.

Extension of the life of the device

As described above, in order for the dishwasher to work out its warranty period, you can not operate it in abnormal conditions. If it fails, and using the hot water system, the warranty may be voided. Ultimately, the consumption of one and a half kilowatts when heated can be much cheaper.

In addition, when connecting cold water, it is diluted with a special salt from the ion exchanger for greater softness. In case of violation of the temperature regime, the adjustment system quickly fails.

Impact on the dishwashing process

The quality of washing the dishes does not change much, because the dishwasher has a thermal relay that heats the water to a certain working temperature. Unless the process speed increases due to the fact that there is no need for heating. Whether such connection of a dishwasher makes sense is a moot point.
