Water Valve and Flood Switch
The water valve is a 120 VAC solenoid valve that
is switched on/off by the control module. The
fl ood switch acts as a safety switch ONLY and
does not control normal operation of the water
valve. The fl ood switch opens the L1 side of the
water valve circuit.
The switch is normally open. The weight of the
fl ood switch fl oat holds the switch closed. The
fl ood switch will not stop the fl ow of water if the
valve sticks open from a mechanical failure.
The water valve can be replaced with the
dish wash er installed.
WARNING: Disconnect power to dishwasher
before servicing water valve and fl ood switch.
Note: To prevent leaks after installation, ensure
that hose-to-valve connection is good and that
clamp is in place.
The water valve is secured to the frame by 2 hex
head screws.

The fl ood switch is held in place by 2 Phillips
head screws.

Drain System
The drain system consists of the following
com po nents:
• Auxiliary drain pump (includes motor and one-
way check valve)
• Drain tube
• Check valve (in line with drain tube)
• Drain hose
The inlet cover prevents large particles from
entering the sump. Water entering the drain pump
is not fi ltered by the fi ne fi lter (metal) or by the
sump fi lter (plastic). The drain pump is mounted
on the sump and contains a one-way check
valve. The drain pump is controlled by the control
module and can be activated using
Service Mode.
Auxiliary Drain Pump Strip Circuit
The drain pump utilizes a 120V AC motor. The
motor should read approximately 16 Ω.
