The black plastic control panel cover popped off my dishwasher. I don't see any broken parts. I've tried to put it back on but can't figure out how. I found a video but it requires that the entire dishwasher be pulled out and the door removed. I've tried running it without the cover but it won't run. Is there an easier way to replace the control panel cover? Otherwise I will have to hire a repairman, and it will probably be nearly as cheap to replace the dishwasher which I've never really liked anyway.
