Water Inlet Valve
The water inlet valve normally does not require removal
for cleaning. Refer to “Water System Checklist” page 109,
if you are troubleshooting water related problems.
1. When the ice machine is off, the water inlet valve
must completely stop water flow into the machine.
Watch for water flow.
When the ice machine is on, the water inlet valve must
allow the proper water flow through it. Press the On/
Off button to energize the ice machine. Watch for water
flow into the ice machine. If the water flow is slow or
only trickles into the ice machine, refer to water system
checklist.
NOTE: The valve can also be energized by navigating to
the service diagnostic menu, selecting control board, then
selecting “enable all relays”.

Warning
Disconnect the electric power to the ice machine and
dispenser at the electric service switch box and turn off
the water supply before proceeding.
Water Dump Valve
The water dump valve normally does not require removal
for cleaning. To determine if removal is necessary:
1. Locate the water dump valve.
2. While the ice machine is in the freeze mode, check
the drain to determine if the dump valve is leaking. If
there is no or little water in the water trough (during
the freeze cycle) the dump valve is leaking.
A. If the dump valve is leaking and debris is not
visible and easily removed, the dump valve must
be replaced.
B. If the dump valve is not leaking, do not remove
it. Instead, follow the “Ice Machine Cleaning
Procedure”.
