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.

The water valve is held in place by two machine
screws.

To Replace Water Valve:

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 toe-kick.

3. Disconnect house plumbing from dishwasher.

4. Remove flood switch.

5. Remove the 2 machine screws holding the

water valve to the frame.

6. Disconnect connector.

7. 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). Pump out water
as necessary using service mode. If an inter-
mittent 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.
