I have a Diplomat Dishwasher ADP8322 and need to replace the Washhpump impeller. I've seen lots of good information on this forum - mostly saying that the washpump is now a CESET one. I only need the plastic impeller - do I really have to spend £99.99 and buy the whole assembly for something that should be pennies to fix? (if so then I'm going to try araldite first). Any more problems with this machine and my wife is shopping! By the way, apart from the positions of the 2 hoses the CESET one looks nothing like mine?
