Troubleshooting - Smeg CW500 Manual

If the system fails to pump out because the drain pump is fouled (as
a result of incorrect filter positioning), proceed as follows:
Bale out the dishwasher with a basin and disconnect it from the
electrical mains.
Unscrew the screw A, release the tang B and lift it.
Check that the impeller of the drain pump underneath the cover
turns freely, and is free from dirt, limescale residues, or pieces of
glass. Never use tools, screwdrivers, scissors, etc.
