A quick and simple search will bring up many, many threads on dishwashers, and I've typed up my Fisher & Paykel rant for the last time, so I'll simply say Don't.

I can summarize what you'll find from your search: Bosch most popular. Since others have posted possible supply problems with Bosch, I'll suggest you also consider Miele. At least equal in performance to the Bosch, but not well known (marketed).

Best to focus your search on a dealer that will provide service and avoid buying from a big-box store. Buy what the dealer services.
