Had 2 of them....
...in a "group home" setting with 10 residents. Without doubt, the best dishwashers I've ever owned. Ran multiple times daily - on Holidays/large events - sometimes 5 or 6 times daily each unit - until the racks began to rust significantly (no complaints here, they were literally run to death). We never pre-rinsed anything. Crusty, dried on, baked on - left for days to dry anything - always came clean - and with cheap (Sam's Club) DW Detergent. Replaced with newer SS Kitchenaids that are non-Bob Load compliant, require much pre-rinsing and high $$$ detergent - and still produce inadequate results, and likely won't be around much longer.
