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.

disassemble and clean it.
B. If the dump valve is not leaking, do not
remove it. Instead, follow the "Ice Machine

shield from its mounting bracket.

counter-clockwise1/4 turn.
