off and on, the Wash/Rinse LED is not activated. As soon as the next
water intake has taken place, the display functions normally.
4. Fault indication after low voltage has been registered (Integrated
models)
If low voltage is registered during a program in operation, the
Start/Stop LED flashes briefly and then switches off for 10 seconds. Low
voltage may be registered, for example, in the following cases:
 There is a drop in main voltage.
 The main switch is switched off and on.
3.11 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.
See Table 080-3 for model-specific fault indications.
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 050-4.24.
3.12 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.
See Table 080-3 for model-specific fault indications.
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 050-4.24.
