Low water level in reservoir.
Distributor tube is restricted.
Build-up of deposits on evaporator
plate.
Inadequate drain system.
Condenser fan air flow is restricted
The selector switch is not in the

Room temperature is too cold.
The selector switch is not in the
"ON" position.
The ice machine is not level
Room temperature is too warm.
Ice deflector is not in place or
secured properly.
Bin level sensing tube needs
adjusting.
Inadequate drain system.
Foreign material in ice bin drain
CORRECTION
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.
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.
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.
Set the rocker switch on the grill of the ice
machine to the "ON" position.
Remove the escutcheon panel and plug the
grid cutter into the receptacle on the side of the
liner.
I
t can take up to 35 minutes to cut through a
harvested ice slab. This is normal operation.
Use a level to check the unit from side to side and
front to rear
Move the unit to an area where temperature is
above 55 o F.
Set the rocker switch on the grill of the ice
machine to the "ON" position.
Use a level to check the unit from side to side and
front to rear.
Move the unit to an area where temperature is
below 90 F.
o
Check to see that the ice deflector is in place
and secured below the grid cutter.
Adjust the bin level sensing tube by simply
pressing directly down on the tube 5 inches from
the front of the tube to get a desired bin level.
Restriction or improperly installed drain lines
will cause water to back up into the ice bin. Make
certain there are no kinks or restrictions in the drain
lines. If necessary, consult a qualified plumber.
Foreign material is restricting or blocking the ice bin
drain located at the right rear corner of the ice bin.
The drain will need to be cleared
