My dishwasher turns on but goes to the wash cycle and just stays there. Also hear a buzzing noise near vent in the door. When I manually press “cancel,” the water pumps out, but pump doesn’t quit. Everything appears to be electronic, so I would guess that the control circuit board is goofy. Is my guess correct?
Hi John,
If the dishwasher runs more then 2 minutes after the cycle has been canceled - most likely the problem is the control board.

Gene: Much thanks for the feedback. When I turn it on it starts washing, as normal, but it never quits the wash cycle. If I press Cancel, it pumps the tub out and then starts to fill back up, and then quits completely.
The first thing I would check is the heating element and the hi limit thermostat.
Measure resistance from ST1 terminal (red/black) ST11 terminal (white) at the control board. It should be about 16 Ohms.
If there is nothing wrong - replace the control board.
If it shows the open circuit then check for continuity the hi limit thermostat and the heating element.
Whichever part is open - it has to be replaced.

I really appreciate your advice, and will check those teminals. Could you tell me where the hi-temp thermostat is? This whole problem started as a result of a blockage in the line that goes to the garbage disposal.
