Part to replace the easily eaten diffuser grid used in some Electrolux and AEG dishwashers. Corresponds roughly to the part numbers 8996461377864 and 8996461377807 from their respective companies.
Edit: October 2014
After over a year of service, the part still functions perfectly with no leaks or other issues. I think I can say this works as planned.
The locking lugs may need filing down. For my model I made them too big and filed them until they were snug. Everything else should fit nicely, but no harm doing some filing if needed.
