Washing machine not heating water: causes and repair

In short: If your washing machine only washes in cold water, the most common cause is a burnt-out heating element, often due to limescale. Other causes are a faulty temperature sensor (NTC) or a relay on the control board. The repair usually means replacing the heating element and takes less than an hour.

Run a descaling programme regularly.
