3.16 Laundry Is Overdried/F55 (Overriding Time Limit Exceeded)
Symptom:
Very long operating time.
F 55 is stored in the fault memory.
Cause:
Short circuit at drum contact strip.
A metal bracket of the drum contact strip is touching the drum casing and has
caused a short circuit. Therefore, the electronics are detecting moisture, even
though the laundry is already dry.
Remedy:
Insulate the bracket from the drum casing by placing an insulating sleeve
(mat. no. 07244210) around the bracket.
Note:
In order to clear this fault message, open and close the door with the
appliance switched on.
3.17 Dryer Shuts Itself Off
Symptom:
Dryer shuts itself off suddenly during operation.
No fault message; no additional symptoms.
Cause:
Not enough supply voltage available.
See Section 090-2.9.
Remedy:
No remedy needed, because the electronics will switch the dryer on again
when they have detected sufficient voltage.
Cause:
The electronic prematurely detects a low voltage.
The values for low-voltage detection have been adjusted. For current low-
voltage detection values, see Table 090-3.
Remedy:
Measure the input voltage to determine if the dryer has shut off in accordance
with the values shown in the table. If possible, measure the voltage while a
drying program is running and heating is switched on.
If the dryer has shut off prematurely, replace the electronic.
