Water Purge Valve
When the machine enters the harvest cycle, the water pump continues to run and the purge valve
opens. This allows mineral laden water to be pumped from the water trough to the drain. This
helps keep the water system clean. The water pump and purge valve de-energizes once the water
is flushed from the water trough. The cam switch controls the length of time that the water pump
and purge valve remains energized see page F7. The purge valve can also be energized
manually by pushing the purge switch. The purge switch is used when cleaning the water system
to flush cleaning solution down the drain. See page B1 for cleaning instructions.
The purge valve must be completely closed during the freeze cycle. If water leaks through the
purge valve during the freeze cycle, the freeze cycle will be extended due to the float allowing
warm water into the trough and poor ice formation will result. The purge valve may be defective or
need cleaning.
The purge valve can be disassembled for cleaning by:
1. Disconnect electrical power form the ice machine.
2. Lift and remove the coil retainer cap.
3. Leave the coil wires attached to the coil and lift coil from the valve body. (Note coil orientation)
4. Rotate the enclosing tube ¼ turn counterclockwise to remove.
5. Remove the enclosing tube, plunger and diaphragm from the valve body
6. Reverse procedure to reassemble.
The purge valve can be easily cleaned or rebuilt without
removing the entire valve body. Dirty or clogged purge
valves are not considered a warranty repair.
