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.
