3.9 Fault Code F01: Water/Heating NTC or Leads Short-Circuited
Symptom:
After this fault is registered, the heating will not be activated and rinse aid will
not be dispensed.
Cause:
NTC temperature sensor R30 or its connection leads short-circuited.
Remedy:
1. Check the temperature sensor and its leads for continuity. At 68°F (20°C),
the temperature sensor resistance should be approximately 14.9kΩ
(± 750Ω); at 77°F (25°C), approximately 12kΩ (± 600Ω) (guide figures only).
2. Check the plug connections.
3. Replace the temperature sensor, if necessary. See Section 050-4.20.
3.10 Fault Code F02: Water/Heating NTC or Leads Open-Circuited
Symptom:
After this fault is registered, the heating will not be activated and rinse aid will
not be dispensed.
Cause:
NTC temperature sensor R30 or its connection leads open-circuited.
Remedy:
1. Check the temperature sensor and its leads for continuity. At 68°F (20°C),
the temperature sensor resistance should be approximately 14.9kΩ
(± 750Ω); at 77°F (25°C), approximately 12kΩ (± 600Ω) (guide figures only).
2. Check the plug connections.
3. Replace the temperature sensor, if necessary. See Section 050-4.20.
3.11 Fault Code F11: Drainage Fault
Symptom:
Water present in appliance and is not being drained off.
Background information:
After each drain pump step, the circulation pump operates for 2 seconds and
heater pressure switch B1/13 checks the water level. See Figure 080-6. If it is
too high (large quantity of residual water remaining in the cabinet), the
drainage time is extended. If, after a further check, the water level is still too
high, then the program is interrupted, the fault code is saved and the drain
pump is activated.
