Fault Code F14: Water Intake Fault: Heater Pressure Switch

Symptom:
The program is interrupted and the drain pump is operated.
See Table 080-3 for model-specific fault indications.
Background information: With the circulation pump operating after a water

2. Check for correct water level within the machine (water level should be
