TROUBLESHOOTING GUIDE
PROBLEM POSSIBLE CAUSE CORRECTION
Ice cubes are too small
(less than 1/2 inch thick).
1. Low ice consumption.
Ice is slowly melting in the ice bin and will affect the size of
the ice cubes. This is normal operation. When the ice bin
needs to be replenished, cubes will return to regular size.
2. Not enough water in reservoir.
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.
3. Distributor tube is restricted.
See “CLEANING YOUR ICE MACHINE” section for cleaning the
unit for proper operation.
4. Build-up of deposits on evaporator
plate.
See “CLEANING YOUR ICE MACHINE” section for cleaning the
unit for proper operation.
5. Inadequate drain system.
Restriction in the drain lines will cause the 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.
6. Leaking drain valve.
Foreign material in the drain valve could cause it to leak. See
“CLEANING YOUR ICE MACHINE” section for cleaning the
unit.
7. Room temperature is too warm. Move to an area where temperature is below 90 degrees F.
Ice cubes are too big
(greater than 3/4 inch
thick).
1. Ice slab not releasing.
See “CLEANING YOUR ICE MACHINE” section for cleaning the
unit for proper operation and cube size.
2. Condenser fan air flow is restricted.
Make certain the grille in the front of the unit is free and
open for proper air circulation.
3. Room temperature is too warm. Move to an area where temperature is below 90 degrees F.
Hollow ice slab.
1. Distributor tube is restricted.
See “CLEANING YOUR ICE MACHINE” section for cleaning the
unit for proper operation.
2. Build-up of deposits on evaporator
plate.
See “CLEANING YOUR ICE MACHINE” section for cleaning the
unit for proper operation.
3. Low water level in reservoir.
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.
