WATER DUMP VALVE
The water dump valve normally does not require
removal for cleaning. To determine if removal is
necessary:
1. Set the toggle switch to OFF.
2. Watch the water float valve. If the dump valve is
leaking the float will continue to add water in the
Off cycle.
• If the dump valve is leaking, remove, disassemble
and clean it.
• If the dump valve is not leaking, do not remove it.
Instead, follow the “Cleaning Procedure”.
Follow the procedure below to remove the dump
valve.
1. Depress and twist the coil 1/8 turn
counterclockwise.
2. Leaving the wires attached, lift the coil assembly
off the valve body.
3. Remove the plunger, nylon gasket and diaphragm
from the valve body.
NOTE: At this point, the water dump valve can easily
be cleaned. If complete removal is desired, continue
with step 4.

Warning
Disconnect the electric power to the ice machine

water supply before proceeding.
