Problem
Possible cause and solution
Knocking noise in the
wash cabinet.
A spray arm is hitting the dishware.
Interrupt the program, and rearrange the items
which are obstructing the spray arm.
Rattling noise in the
wash cabinet.
Dishware is moving around in the wash cabinet.
Interrupt the program and rearrange loose pieces.
A foreign object (e.g. cherry pit) has become lodged
in the drain pump.
Remove the foreign object from the drain pump
(see: “Cleaning the drain pump and non-return
valve”)
Knocking noise in the
water pipes
This may be caused by the on-site installation or the
cross-section of the piping.
However, this will not affect the dishwasher function
in any way.
If in doubt, contact a plumber.
