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 trouble-
shoot the machine.
Water Remaining in the Wash
Compartment
• 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 use and care
manual.
Water Level Problems - DDW24S
When servicing a DDW24S dishwasher it is important to
check the water level in the machine. This is particularly
important when programming the time-controlled water
intake. Too low or too high water level can cause poor dish-
washing results.
IMPORTANT:
Always allow the machine to
take in and drain the water a few times before checking the
level.
Check the level against the lower spray arm hub In the
event of too low water level, the filter in the inlet valve must
always be checked and rinsed clean of any sediment. The
inlet hose with a 3/8” connection at both ends.

or oven dishes, choose a heavier program.
• Check that the customer is using a suitable dishwash-
ing detergent, preferably one with proven good results.
