SERVICE
In the “What to do, if …” section a number of malfunctions are listed
that you can rectify yourself. In the event of a malfunction, look there
first.
Is it a technical malfunction?
Then please contact your customer service centre. (You will find addres-
ses and telephone numbers in the "Customer Service Centres" list.)
Always take the time to prepare yourself for the call. By this means you
will make diagnosis of the problem easier and also make it easier to
decide if a customer service visit is necessary:
Please determine as accurately as
possible:
• How is the malfunction noticea-
ble ?
• Under what circumstances does
the malfunction occur?
Prior to the telephone call it is
imperative that you make a note of
the following appliance code num-
bers that are given on the rating
plate:
• PNC Code (9 digits),
• S-No Code (8 digits).
We recommend you to record the code numbers here so that you
always have them at hand:
PNC . . . . . . . . .
S-No . . . . . . . .
When will you be charged, also during the warranty period?
• when you could have rectified the malfunction with aid of the Table
of Malfunctions (see “What to do, if ...” section),
• if the customer service engineer has to make several calls because he
was not given important information prior to his visit, and therefore,
e.g., had to fetch replacement parts. You can avoid multiple calls if
you prepare yourself well for the telephone call, as described above.
