Fault
Possible cause
Troubleshooting
Door (fold-down door) does not open
90°
Not a fault. Due to construction.
► Advise customer:
Due to its construction, the fold-down door can be opened to 87 +/- 1°.
An opening angle of 90° cannot be achieved.
This does not restrict the use of the appliance.
Door (fold-down door) closing is
displayed (only microwave appliances)
Door plunger bent.
Door (fold-down door) cannot be
► Replace defective door switch.
► Replace bent door plunger.
Clock gains > 1 minute every day
Conductor (PE connection) defective or
missing.
-
Appliance must
not
be operated with defective or missing conductor!
► Connect protective conductor correctly.
► Run a safety test according to VDE 0701.
Time - ist fast / slow
(Deviation < 6 minutes per half year)
Not a fault.
-
The time for appliances is derived from the mains frequency or the frequency of an
oscillating crystal.
-
However, the slight fluctuations of the mains frequency result in large deviations of
the time.
-
For this reason, the time is derived from the frequency of an oscillating crystal for
all IC 6 appliances.
► Advise customer:
The time must only be compared with the actual time (for example time of a radio
clock).
The time must not be compared with the times of other household appliances, as
all these appliances can have slight time deviations due to component tolerances
and different thermal stresses.
The deviation must be observed across a time period of 6 months. Consideration of
shorter periods is not possible.
A deviation of time of +/- 6 minutes in half a year is normal and corresponds to
technical specifications.
(Deviation > 6 minutes in half a year)
Operating module defective.
-
The operating module must only be replaced if the deviation of time of > 6 minutes
was determined under the following conditions:
► 1. The time was correctly set.
► 2. The time was compared with the actual time (for example the time of a radio
clock) and not with other household appliances.
► 3. The observation period was half a year. Observation of shorter periods and
extrapolation to half a year is not permitted.
► Replace the operating module.
