GE Profile PDW9280L00SS start/reset button lite but unresonsive

I have had my dishwasher just over 10 years and have had no problems with it. Today after a wash cycle there was a repeating beep occurring about 15-20 seconds apart. Pushed start/reset button without effect. Opened door and found moderate amount of water in bottom of machine. Read manual without much satisfaction. Turned off breaker for a minute and when turned back on the beep stopped. The start/reset button is flashing and the added heat button is constantly lit. Buttons are unresponsive when pushed. Any ideas on a fix or should I have GE tech come visit $$$? Thanks in advance Bjaco
