The washing machine does not heat the water: causes and solutions

Among the breakdowns that most often occur in washing machines, it is worth highlighting the lack of water heating. A variety of reasons can cause this effect, followed by the failure of a specific component, sensor or part. To understand all the issues related to this phenomenon, it is suggested that you learn more about repairs on


Any owner of the unit can determine the lack of heating. It is worth turning on the machine, loading things, closing the hatch and setting the washing mode, where the water temperature should reach +60°C. If the door glass does not become warm within 15-20 minutes, then the machine is not heating the water. In such a situation, you should contact specialists and order repairs on mannyappliances.

The reasons for this phenomenon may be:

  1. No voltage in the socket, faulty power cable.
  2. Incorrectly set parameters on the control unit.
  3. Oxidation of contacts, damage to insulation or breakage of wires supplying the thermostat and heating element.
  4. There is too much limescale or calcium deposits on the surface of the heating element when it cannot heat the water to the desired temperature.
  5. Failure of the heating element or water heating sensors, especially the thermostat and pressure switch.
  6. Damage to the electronic control unit.

To understand the causes of the phenomenon, it is worth finding out more information on, where experts give recommendations.


First, check the outlet by plugging in another electrical appliance, for example, a table lamp. If it is working, then inspect the plug and cord of the machine for integrity and the absence of soot and traces of oxidation of the contacts.

The set operating mode is checked and what water temperature should be used. If all parameters are normal, there is no heating, then the equipment is disconnected from the outlet, the water is completely drained and things are removed.

The machine is placed in the center of the room, where there is space to approach from any side and there is high-quality lighting. They remove the front and back walls, inspect all the wiring, find out whether there are mechanical damage, oxidation of contacts, traces of soot from a short circuit.

Next, the heating element is dismantled and removed. If there is sediment, careful mechanical and chemical cleaning of the entire surface is carried out. Oxidized contacts can also be cleaned. All damaged wires must be replaced.

The sensors and control board are checked with special diagnostic devices. This work is carried out only by a master, as is the replacement of these elements.
