Miele F4137 — Dishwasher
[ACTIVE]The specific disinfection program fails or fails to reach the required high temperature.
The heating system has a problem specifically at high temperatures. The NTC1 probe may be inaccurate in this range, or the heating resistor is too scaled to heat effectively.
1. Follow the diagnostic procedure for error F4136, testing the NTC probe. 2. Inspect the heating element for excessive limescale deposits. 3. Carry out descaling of the machine. 4. Check that the water pressure is sufficient for proper filling, as a low level affects heating.
