My Bosch dishwasher model #SHU43C06UC has gone wacky!?

My Bosch dishwasher, model #SHU43C06UC has gone wacky! The "Sanitized" light had quit coming on about a week ago. The other day while it was running I noticed that there were about 30 minutes left in the cycle. A while later the countdown read 40 something minutes left! It would not stop running! I tried running it on rinse & hold. It seemed to count down OK until it got to one minute left. It would not stop running and never drained. There is only one service company in our area that works on Bosch and they want over $150 to diagnose the problem. We are thinking about ditching this Bosch and buying a new one that is anything BUT a Bosch. Can anyone help? Thanks!
