dishwasher would not drain unless we turned it off and on several times.

Unplugged and shut off electrical breaker. Removed inside door panel. Used flat shank to open compartment housing control board. Connected each wiring harness individually from old control board to new control board as I went. At that point, I snapped new control board in place. Tightened door panel. Plugged dishwasher back in.....reset breaker. Works great.
