billy... I've gone further than that, I use the computer myself (probably much like your repairman did) and was able to repair our washing machine and dishwasher for next to nothing.
The days are gone where appliances were more mechanical than electrical. Now everything seems to have a computer on board that can pop out an error code to tell you what is wrong. The down side is that these computers are what tend to break most often and they cost the most money to replace!
Penny- I'm waiting until they can fix ugly. I'll go in for my new face then.
