Section 4
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. Set the toggle switch to ICE.
3. While the ice machine is in the freeze mode, check
the water trough 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, remove,
disassemble and clean it.
B. If the dump valve is not leaking, do not remove
it. Instead, follow the "Ice Machine Cleaning
Procedure".
Follow the procedure below to remove the dump valve.
!
Disconnect the electric power to the ice machine at
the electric service switch box and turn off the water
supply before proceeding.
1. If so equipped, remove the water dump valve shield
from its mounting bracket.
2. Leaving the wires attached, twist coil and rotate it
counter-clockwise 1/4 turn.
3. Lift the coil assembly off the valve body.
4. Remove the spring, plunger, and nylon gasket from
the valve body.
NOTE: At this point, the water dump valve can easily be
cleaned. If complete removal is desired, continue with
step 5.
