Lengthy Periods Out Of Use; Troubleshooting - Smeg UD505DSUK User Manual

9.3 Lengthy periods out of use

If the dishwasher is to be out of use for a fairly long period of time, the detergent and rinse aid dispenser devices must be
emptied to prevent crystallisation and damage to the pumps: Remove the intake hoses from the detergent and rinse aid
containers and place them in a container of clean water, then perform a few wash cycles followed by a complete pump-out.
Finally, turn off the master switch, close the water intake valve and leave the door ajar until the interior is completely dry. The
detergent and rinse aid intake hoses must be put back into the containers when the dishwasher is returned to service, taking
care not to swap them over (red hose = detergent, blue hose = rinse aid).

10 TROUBLESHOOTING

In case the pump is not working properly, follow the steps
below:
Empty the dishwasher out using a container and disconnect the
power.
Remove screw A, release tab B and lift it upwards.
Make sure that the covered drain pump impeller can rotate
freely, and that there are no dirt residues, limestone, or pieces
of glass. Do not use tools, screwdrivers, scissors, etc.
