I have a Kenmore Elite Dishwasher (66513199k902). When the wash cycle finishes there is a substantial amount of water in the entire bottom of the dishwasher. Approximately a 1/2". When I hit the Cancel Drain button the water completely clears. I have replaced the electronic control board and the pump. When I hit the cancel drain button I can see the stream of water entering my garbage disposal from the dishwasher so the drain line does not appear to be blocked.

Any other repair ideas?
