Fault Possible cause Troubleshooting
Insufficient cleaning / food stains in storage drawers
and on glass plates / stagnant condensation water in
drawers / blocked defrost drain outlet
▶
Advise customer:
Regularly clean of all parts of appliance compartment with lukewarm
water and mild detergent.
Musty smell in case of prolonged periods being out of
operation
Doors closed / Appliance not cleaned Required tools:
Cleaner for intensive cleaning of refrigerat-
ors
[00311910]
1. Advise customer:
Switch off the appliance.
2. Advise customer:
Defrost the freezer compartment (if available).
3. Advise customer:
Clean the appliance thoroughly.
4. Advise customer:
Keep doors open in case of extended periods out of operation.
Off-odors coming from the appliance exterior Dirty water drainage system The condensation water occurring in cooling and freezing appliance is led
to an evaporation tray at the appliance exterior by a defrost outlet, where
it is continuously evaporated.
In normal use just clean water –having just a very faint smell coming from
the stored foods - is transferred to the evaporation tray. The evaporation
of this conventional condensation water will not be noticeable.
In static cooled appliances food components or liquid foods may be trans-
ported to the evaporation tray via the defrost drain outlet. This may hap-
pen if fluids are spilled within the refrigerator compartment or solid food
components such as crumbs are transferred to the defrost drain outlet
upon storage or appliance cleaning.
The evaporation of such water-food mixtures may cause a noticeable
smell as food components such as proteins, fats and carbohydratesare
slowly decomposed by chemical, biochemicaland microbialprocesses.
These decomposition processes may take several weeks, always de-
pending on the amount and type of the water-food mixture within the
evaporation pan and location specific ambient conditions.
Along with that the formation of a biofilm may occur which will be clearly
visible (slimy-greasy layer, especially at boundary layers) .Especially
strong smell results from the decomposition of dairy products such as
cream, milk or fatty dressings and broth.
▶
Clean the drain water outlet, the drain hose and the evaporation pan.
For the complete removal of food components, stains and a possible
biofilm from the evaporation pan a conventional vinegar cleaner is
recommended.
