Reasons that the dishwasher won’t heat the water

The dishwasher may also refuse to heat the water the first time it is used. It is clear enough that the device can’t be broken, therefore, most likely, the reason is in the wrong installation.

Incorrectly set modes are the most common reason why the dishwasher does not heat the water. When the heating mode indicator in the electromechanical device is at around 40 degrees, and the display shows 90, the unit will heat the water to no more than 40.

Dishwashers made by world-renowned companies such as Bosch, Ariston, Electrolux, Indesit, etc. have a delicate wash mode. If it is turned on, the unit will also not heat the water more than 40 degrees.

The filter in the dishwasher is an important functional part that prevents dirt and debris from entering the working elements. Clean the dishes of food debris before loading. Food remnants accumulating in the filter causes problems with the water circulation in the device resulting heating element turning off. It is sufficient to clean the filter to resume the normal operation of the appliance.
