miele dishwasher 1220 sc , problem in drying engine , lot of noise, probably out of order , new one part cost 300 euros, pity for an expensive new miele with low quality
Debri has been sucked into the drying fan.
Simply clear the obstruction & it will be fine.
It may need a new fan unit, but unlikely.
Take off the bottom plinth, shine a torch in & you will probably see the problem - a piece of plastic, or a leaf . or a piece of paper .
