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 dump valve’s clear plastic outlet drain hose for leakage.

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 “Cleaning Procedure”.

Follow the procedure below to remove the dump valve.

Important

The plunger and the inside of the enclosing tube must be completely dry before assembly.

NOTE: During cleaning, do not stretch, damage or remove the spring from the plunger. If it is removed, slide the spring’s flared end into the plunger’s slotted top opening until the spring contacts the plunger spring stop.

5.Remove the valve body.

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

7.Remove the two screws securing the dump valve and the mounting bracket.
