Is it possible to connect a dishwasher to hot water?

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 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 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;
• coarse water filter;
• adjustable wrench, pliers, Teflon tape.

Connection procedure sequence

The connection is made in the following order:

• cut off the water supply;
• prepare the outlet of the water pipe;
• connect the 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 the hot water supply system always has high 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.

Attention! It is strictly forbidden to use an ungrounded dishwasher! Possible electric shock.

Pros and cons of connecting a dishwasher to hot water

A question of saving

Will you be able to save money? A difficult question, and here's why:

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

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 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.
