PROBLEM
POSSIBLE CAUSE
CORRECTION
Ice cubes are too small
Low ice consumption
Ice is slowly melting in the ice bin and will
(less than 1/2” thick)
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.
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.
Distributor tube is restricted.

Leaking drain valve
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.
Inadequate drain system.
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

Condenser fan air flow is restricted.
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.
