I've checked for food and debris around the drain and it's clear.  When I hit the off/drain switch, the sprayer runs.  Same thing happens when I run a cycle, the sprayer seems to be running when it should be pumping the water out.

Is the pump getting voltage during the drain cycle?

I'm assuming that it is. When I manually select "Drain", the pump runs, however it's pumping the water thru the spray bars as if it's in the "wash" cycle.

Thanks for posting the diagram, Reg.

Finnster, I think you're gonna find that the wash winding is getting energized during the drain cycle=bad control board. Part link for new control board==> http://www.repairclinic.com/PartDetail/Control-Board/940209?modelNumber=MDB7100AWB

Thanks, I suspect you're correct. I'll put a meter on it tonight.
