Cleaning the drain pump and non-return valve

If the water has not been pumped away at the end of a program,
there may be a foreign object in the drain pump or blocking the non-
return valve. These are easy to remove.
Disconnect the Commercial Dishwasher from the water supply and

the electrical supply (switch the dishwasher off, unplug it, or
disconnect or disable the breaker).
Take the filter combination out of the wash cabinet (see "Cleaning

and care").
Open the locking clamp.

Lift out the non-return valve and rinse well under running water.

Make sure that the vent on the outside of the non-return valve is not

blocked (this vent is only visible after the non-return valve has been
taken out). If it is blocked, use a pointed object to release the
blockage.
