My Zanussi dishwasher, model DW925, has suddenly decided it would be a
good thing to stop near the end of the program. It finishes the wash
and rinse cycles OK, but during the drying cycle it stops and buzzes,
clearly waiting for a signal that never arrives. If I move the program
on a bit by hand, the buzzing stops and the program finishes properly
about 7 or 8 minutes later, with everything properly washed and dryed.
Anyone got any ideas as to what it waits for please?
