Water Valve and Flood Switch

The water valve is a 120 VAC (L1) 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.

Water Valve Replacement

The water valve can be replaced with the dish- washer installed.

WARNING: Disconnect power to dishwasher before proceeding.

1.Turn off water supply to dishwasher.

2.Remove toekick.

3.Disconnect house plumbing from dishwasher.

4.Remove 2 screws and valve from dishwasher frame.

5.Disconnect connector.

6.Move clamp up, away from valve, and remove valve from hose.

Note: To prevent leaks after installation, ensure that hose-to-valve connection is good and that clamp is in place.

Water Valve Test

1.Attempt to activate water valve using service mode (see Service Mode chapter). 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 50 - 71 seconds per activa- tion and should not turn on and off during the 50 - 71 second activation time.

2.If the water valve is not operating properly or
