It sounds like this isn't a warranty repair. Why did you call A&E for service - they have a terrible reputation. What did you pay for already - the part and service or just the service call? Did you pay by credit card? If I were you, I'd call back, get a supervisor, cancel the call and demand a refund. If they refuse, dispute the charge on your credit card. You could just dispute the portion for the service call and keep the part. Then I'd call a local appliance repair service with a good reputation. Having the part in hand (assuming it's really the problem) will avoid 2 trips by the new place. I think A&E stays in business by locking in large contracts with appliance manufacturers. By the way, I think you'd have better luck getting it fixed sooner if you could schedule a weekday appt. but that may not be possible in your situation.

Your comments and suggestions are very good. Yes, my KitchenAid dishwasher, the Superba model, is out of warranty. The appliance has been of high quality, though, and it never dawned upon me that a reputable manufacturer would risk loss of reputation and sales by partnering themselves with what turned out to be the buffoons at A & E. The first technician said I had to pay in full in advance. I assumed that was because of having to order the part. And I paid by check, more out of habit than anything else. My next dishwasher will be a Miele, although it looks like I had better start with my due diligence way in advance.

People need to understand that it isn't necessary to go through the appliance manufacturer for repair ... except in case of warranty, and not always even then. Check your phone book and call a local independent servicer.

Also, parts can be bought online from any number of sources, and there's DIY service info available.
