Been out to a very old dw today, it has a model number on the door and facia that are different:
DI720
D75353
7370405
Cust says machine is sticking in cycle. Had a look today found sticking just before the wash(the litlle brush emblem) and advancing it moves it on. I checked all the usual, element, wiring in door etc.
Havent seen one of these before so any other ideas would be helpful.
