Dishwasher fills up with water but will not cycle. It tries a few times to start then dumps the water and stops?

Joe for Model Number KUDP02CRBS3

ANSWER Hello Joe. Pump motor seized up (will not turn). 1. Unplug dishwasher or disconnect power. 2. After accessing chopper system, verify rotation of impeller by rotating chopper blade. Rotation should require only moderate force. If rotation is difficult or not possible, replace pump and motor assembly. Pump motor windings open, or loose/open connection in wash pump circuit. 1. Unplug dishwasher or disconnect power. 2. Check the resistances of pump motor windings and all connections in the wash circuit, including the pump motor start capacitor. Door switch not making contact consistently: ¦ Faulty or sloppy door latch assembly (which can be aggravated by high door closure force, keeping strike plate from fully seating). ¦ Faulty door switch (high resistance). NOTE: Neutral switch on plastic tub models is only in series with motor and heater; other loads are not affected. 1. Unplug dishwasher or disconnect power. 2. Measure resistance of door switch contacts while checking mechanical operation of latch assembly. Confirm switches not loose from assembly. Check strike plate and door closure. Damaged motor start capacitor. 1. Unplug dishwasher or disconnect power. 2. Disconnect capacitor leads and confirm capacitance is as labeled on part; or check resistance for open circuit across the terminals. Replace if open.
