Miele Dishwasher Error Code F24
Heating circuit fault — heater relay or temperature sensor
The control expected the heater to bring the water to temperature but the heating circuit did not respond as expected, so it stops with F24. The fault sits in the heating circuit — most often the heater relay on the board, the NTC temperature sensor, or the heating element itself.
