Noise
Faults that are plainly due to incorrect operation or inadequate maintenance may not be dealt with under the guarantee. Appropriate instructions for use and maintenance may be
found in the specified chapters of the instruction manual (IM) and brief description (BD).
Experience shows that, when recording a fault report it is important to establish not only the symptoms observed but also the circumstances in which the fault occurs.
•
Is the problem present all the time, does it occur sporadically or at specific intervals?
•
Were different programmes or detergents being used or tested?
•
Does the problem date back to a specific event (new tableware, change of detergent, ...)?
The functional test must be carried out in the customer service test programme using the “glass door”.
Fault
Possible cause
Troubleshooting
Foreign object in pump.
► Clean the drain pump. (See instruction manual)
Drain pump cover is loose
► Correctly latch the drain pump cover in the body of the pump (see instruction
manual, Cleaning and maintenance)
Noises during the draining process
Drain pump is defective
► Replace the drain pump.
Domestic installation
-
Rapid opening and closing of the valve can give rise to a water hammer in the
water pipe (not a fault in the appliance). Engage a water installation technician to
repair it.
Noises when water is running in
Flow noise from the water.
► Advise customer:
Flow noise is normal and depends on the installation. If necessary, have a water
installation technician check it.
Spray arm is striking dishes.
-
Utensils are not correctly loaded.
► Advise customer:
Arrange the utensils so that they do not block the spray arm (see instruction
manual).
Light utensils move when they are
sprayed.
► Advise customer:
Arrange the utensils correctly (see instruction manual).
Rattling noises while washing
The sprayed water hits the top of the con-
tainer and (when partly loaded) sounds
like rattling utensils.
-
If the appliance is only partly loaded, arrange the utensils to cover the area.
► Lay some plates horizontally. The noise should stop.
