Service Diagnostics and Procedures–Disassembly
Water Valve
The unit uses a 120VAC valve to supply water to the
ice maker. If water valve does not operate properly,
the following could occur: no ice production, small or
hollow ice cubes, flooding of ice container. Mineral
content can cause lime build up in the mold, wicking
of water over the mold, and poor cube release.
Mineral content can also restrict saddle valves.
Verify water supply line is ON, water pressure is
not below 20 psi and saddle valve is fully open.
Clear restrictions by fully closing and opening valve;
dislodge sediment (if necessary, remove valve and
enlarge pierced hole to 3/16” diameter with a drill and
reinstall saddle valve). Make sure water line to unit is
not pinched/kinked/clogged, ice is not present in inlet
tube blocking water flow, and water pressure is not
above 120 psi.
Water fill can be increased by turning the adjustment
screw counterclockwise and decreased by turning
the screw clockwise. One half turn will adjust the fill
by approximately two thirds of an ounce. If supply is
good, replace water valve. If no voltage is present,
verify harness. If good, replace module.
