We have the Armstrong brand dishwasher, been going strong now for years and really reliable, Uses stuff all power and is reasonable on the water bill too, pretty quiet in the operation mode and leaves the dishes etc sparkly clean..
The only real time it has had problems, is if its had too many beers prior to being set into operation..
Sorry couldnt help it, The last one we had was a Westinghouse from memory, never had a drama with it in over the 5 years we lived there ..
