Troubleshooting

Dishwashing results

Check the following points if the dishes are not
clean (always begin by checking any fault codes
and the most recent fault indication in the
service menu):
• That the customer is using the right
dishwashing program.
• If heavily soiled dishes are being loaded,
such as pots or oven dishes, choose a
heavier program.
• Check that the customer is using a suitable
dishwashing detergent, preferably one with
proven good results.
• Detergent is a perishable product. Check
that the detergent is not too old and
that the customer is using the right
amount. Most importantly not too much
detergent.
• For machines with a water softener, dose
as for soft water.
• Check that the customer is loading the
machine correctly.
• Check that no dishes are preventing the
spray arms from rotating and that the
holes are not clogged.
• Check that the machine has the right
water level. See the Water level section for
more information.
• Check that the access plug on the left side
of the bottom drain by the drain pump is
in place.
• Check that the machine heats to the right
temperature.

Common faults

If the dishwasher does not work, you should
first check whether this is due to a simple fault,
something that the customer can rectify. Use
the following questions to troubleshoot the
machine.
The machine will not start
• Has the house breaker/fuse been tripped
or blown?
• Has the machine been turned on?
• Is the door properly closed?
• Is the water supply turned on?
If the answer to any of the above questions is
"YES" and the machine seems to lack power,
first check that there is power at the main
power switch and the control unit. Replace any
faulty component.
Water remaining in the machine
• Is the drain hose blocked? Check the
connection to the household drain.
• Is the drain hose kinked?
• Are the filters blocked?
• Is the drain pump blocked?
• Is the access plug on the left side of
the bottom drain by the drain pump
incorrectly fitted?
If the fault cannot be found with the help
of this chapter, open the service menu and
perform a function test on all components
For more information, see the machine's
operating instructions.
