TROUBLESHOOTING GUIDE
PROBLEM POSSIBLE CAUSE
Unit does not operate. The unit is unplugged
Breaker is tripped or fuse is blown.
Ice machine selector switch is in the
"OFF" position.
Unit operates but does not The unit has just been started and
produce any ice. it has been less than 6 hours.
Typical ice production cycle can
take up to 1.5 hours.
The selector switch is in the "OFF"
or "CLEAN" position.
No water in the reservoir.
Distributor tube is restricted.
Build-up of deposits on evaporator
plate.
Condenser fan air flow is restricted
Room and/or water temperature
is too warm.
Leaking drain valve
Inadequate drain system
Grid cutter is unplugged
Ice is not clear Low water in level in reservoir.
Softened water supply
Room temperature it too cold.
CORRECTION
Plug in the unit.
Reset breaker or replace fuse. Check to make
sure there is not a short in the electrical circuit.
Set the rocker switch on the grill of the
machine to the "ON" position.
Ice produced when the unit is initially
started will melt off in the bin. This is normal
operation. Check the unit in 24 hours for ice
accumulation in the bin.
Check the unit in 24 hours for ice
accumulation in the bin.
Set the rocker switch on the grill of the
ice machine to the "ON" position .
Make sure that the reservoir drain plug is installed.
Check the water line to the unit to make sure it is
on and that there are no restrictions or kinks in the
line. Check all filters to make sure they are not
restricted or plugged.
See "Cleaning the Ice Machine System" section for
cleaning the unit for proper operation.
See "Cleaning the Ice Machine
System" section for cleaning the unit for proper
operation.
Make certain the grill in the front of the unit is free
and open for proper air circulation. Check and clean
the condenser coil by removing the grill in the front
of the unit. Clean the condenser with a vacuum and
brush attachment.
Move the unit to an area where ambient
temperature is below 90°F. The unit should not be
placed next to a heat source such as an oven.
Check for cold water connection.
See "Cleaning the Ice Machine System" section for
cleaning the unit. This will also dissolve and flush
out foreign material in the drain valve.
Restriction in drain lines will cause ice in the bin to
melt. If using a gravity drain, make certain there are
no kinks or restrictions in the drain lines. If using a
drain pump, check the inlet screen, discharge line,
and vent line for any build-up or restrictions.
Plug in the grid cutter so that ice slabs can be cut
into cubes.
Make sure that the reservoir drain plug is installed
properly. Check the water line to the unit to make
sure there are no restrictions or kinks in the line.
Check all filters to make sure they are not restricted
or plugged.
Make certain that water line is not connected to the
water softener.
Move to an area where room temperature is above
.

PROBLEM POSSIBLE CAUSE
Ice cubes are too small Low ice consumption
(less than 1/2" thick)
Not enough water in reservoir.
Distributor tube is restricted.
Build-up of deposits on evaporator
plate.
Leaking drain valve
Inadequate drain system.
Room temperature is too warm.
Ice cubes are too big Ice slab not releasing.
(greater than 3/4" thick)
Condenser fan air flow is restricted.
Room temperature is too warm.
Hollow ice slab Distributor tube is restricted.

and produce ice.
Ice bin is full.
Room temperature is too warm.
Ice machine is not level.
Ice cubes are sticking Ice consumption is low.
together.
Room temperature is too warm
CORRECTION
Ice is slowly melting in the ice bin and will
affect the size of the ice cube. This is normal
operation. When the ice bin needs to be
replenished, cubes will return to regular size.
Make sure that the reservoir drain plug is installed
properly. Check the water line to the unit to make
sure there are no restrictions or kinks in the line.
Check all filters to make sure they are not restricted
or plugged.
See "Cleaning the Ice Machine System" section for
cleaning the unit for proper operation.
See "Cleaning the Ice Machine System"
section for cleaning the unit for proper operation.
See "Cleaning the Ice Machine System" section for
cleaning the unit. Cleaning the unit will also dissolve
and flush out foreign material in the drain valve.
Restriction in drain lines will cause ice in the bin to
melt to a thinner cube. If using a gravity drain, make
certain there are no kinks or restrictions in the drain
lines. If using a drain pump, check the inlet screen,
discharge line, and vent line for any build-up or
restrictions .
Move to an area where temperature is below 90°F.
See "Cleaning the Ice Machine System"
section for cleaning the unit for proper operation.
Make certain the grill in the front of the unit is free

brush attachment.
Move to area where temperature is below 90°F
See "Cleaning the Ice Machine System" section for

See "Cleaning the Ice Machine System"
section for cleaning the unit for proper operation
and cube size.
Make sure that the reservoir drain plug is installed
properly. Check the water line to the unit to make
sure there are no restrictions or kinks in the line.
Check all filters to make sure they are not restricted
or plugged.
The unit will automatically shut down when
ice reaches the sensing tube.
The unit will automatically shut down when ice
reaches the sensing tube and has completed the
harvest of the ice slab.
Move to an area where room temperature is below
90°F.
Use a level to check the unit from side to side and
front to rear.
Use the ice in the bin frequently. Ice will stick
together if left in insulated bin over long periods of
time.
Move the unit to an area where temperature is
below 90°F.
