Water Valve and Flood Switch
The water valve is a 120 VAC solenoid valve that is switched on/off by the control module. The flood switch acts as a safety switch ONLY and does not control normal operation of the water valve. The flood switch opens the L1 side of the water valve circuit.
The switch is normally open. The weight of the
flood switch float holds the switch closed. The flood switch will not stop the flow of water if the valve sticks open from a mechanical failure.
The water valve can be replaced with the dishwasher installed.
WARNING: Disconnect power to dishwasher before servicing water valve and flood switch.
The flood switch is held in place by 2 Phillips head screws.

Water Valve Test
Note: The detergent pump will also operate during the water valve test.
1.Attempt to activate water valve using Service Mode. Pump out water as necessary using Service Mode. If an intermittent failure is suspected, activate water valve 5 times using Service Mode. Water valve should stay on for 75 to 95 seconds per activation and should not turn on and off during the 75 to 95 second activation time. A normal fill will be approximately 1.2 gallons.
2.If the water valve is not operating properly or water level is low, check the following:
•Water valve, flood switch, flood switch float and stem, transorb, and then main control. The flood switch should open when the water level is approximately
•Resistance through the water valve solenoid coil is 725 Ω to 1200 Ω.
•Clogged screen in water valve.
The water valve is secured to the frame by 2 hex head screws.
