The wash cycle starts fine, fills and starts the pre-wash. At some point it stops, lights still on indicating the wash cycle is active, but there is no noise. If I whack the control panel area then the cycle continues after several seconds (washing action). This has been happening more frequently over the last couple weeks. We are not selecting heated wash or rinse. I suspect the timer is getting stuck, but I think it is a digital timer so I don't know what the 'jolt' is causing to get back on track. I am thinking about replacing the control panel, but don't want to jump in and spend the money unless that is the real problem.

There have been times when I think the dishwasher has just sat there for a couple hours waiting to be jolted back on track.

Thanks
