Maintenance Section 4

ADDITIONAL COMPONENT REMOVAL

The following components may be removed for easier access in some installations or they may need to be removed and cleaned to correct an operational problem.

Water Inlet Valve

The water inlet valve normally does not require removal for cleaning. Refer to Section 5 for a list of causes for “No Water Entering Water Trough” or “Water Overflows Water Trough.

1.When the ice machine is off, the water inlet valve must completely stop water flow into the machine.

2.When the ice machine is on, the water inlet valve must allow the proper water flow through it. Set the toggle switch to ON. Watch for water flow into the ice machine. If the water flow is slow or only trickles into the ice machine, refer to Section 5.

Follow the procedure below to remove the water inlet valve.

!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.

1.Remove the 1/4” hex head screws.

2.Remove, clean, and install the filter screen.

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 ICE.

2.Verify the water trough fills with water at the beginning of the freeze cycle.

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.

!Warning

Disconnect the electric power to the ice machine at the electric service switch box and turn off the water supply before proceeding.

1.Leaving the wires attached, twist coil and rotate it counter-clockwise1/4 turn.

2.Lift the coil assembly off the valve body.

3.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 4.

NOTE: During cleaning, do not stretch or damage the spring.

4.Remove the tubing from the dump valve by twisting the clamps off.

5.Twist the valve body to remove from mounting bracket.
