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 prop-
erly. 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 restric-
tions.
6. Leaking drain valve.
See “CLEANING YOUR ICE MACHINE” section for
cleaning the unit. This will also dissolve and flush out
foreign material in the drain valve causing it to leak.
7. Room temperature is too warm.
Move to an area where temperature is below 90 de-
grees 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 restrict-
ed.
Make certain the grille in the front of the unit is free and
open for proper air circulation. Check and clean the
condenser coil by removing the grille in the front of the
unit. Clean the condenser with a vacuum and brush
attachment.
3. Room temperature is too warm.
Move to an area where temperature is below 90 de-
grees 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 prop-
erly. 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.
