The water valve is a 120 VAC solenoid valve that is
switched onloff 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 L 1 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.
The water valve is secured to the frame by 2 hex
head screws.
Note: The detergent pump will also operate during
the water valve test.
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 l14-in. above the
base (bottom) of the float dome.

coil is 725 $ 2 to 1200
a.
