Dishwasher repair... Or for parts?

My Miele G643 dishwasher has developed a small leak - I think it’s just a knackered seal. Google has revealed a few laughably expensive sources for two pieces of rubber gasket. Anybody know of a good source for spares? Or know someone with a magic gasket collection and intimate knowledge of dishwashers who could the job for a reasonable price?

got a picture?

Update - an engineer has tried everything he can think of, and decided an electrical component somewhere has failed. It may be 12-15 years old. Deemed beyond economic repair…
So… Any dishwasher experts listening who fancy a (paid) repair challenge?
Or… Anyone want any components or materials from it before I get rid?
