My dishwasher seems to run ok for a while in the beginning but then, at some point, it starts to sound as though it is shorting out. kind of like a loose extension cord on something that isn't plugged in completely. It eventually brings up "er", an error. if I try to run it on a rinse cycle, all I get is an "er". Am I looking at a control board here? Please help. I would call someone to look at it, but my work schedule does not allow me to be home when anyone is able to schedule.
Thanks
