Had a similar problem with a Neff dishwasher. However grease stayed on the filters. Tried several things and ended up with dishwasher cleaner from the supermarket, which did the trick (although it did smell!) I would be worried about putting something too caustic in there as it may damage the seals in the pumps and heaters. BTW, spirit vinegar is very good for removing scale and nasty smells if you don't like the artificial smell of the cleaners. Doesn't remove grease very well though.
