TROUBLESHOOTING GUIDE
PROBLEM POSSIBLE CAUSE CORRECTION
Ice is not clear.
1. 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.
2. Softened water supply.
Make certain that the water line is not connected to the
water softener.
3. Room temperature is too cold.
Move the unit to an area where room temperature is above
55 degrees F.
Low ice production. Unit
is running, has run over
a 48 hour period, and
there is little ice in the
bin.
1. Low water level in reservoir. Make sure that the reservoir drain plug is installed properly.
2. Distributor tube is restricted.
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. Build-up of deposits on evaporator
plate.
See “CLEANING YOUR ICE MACHINE” section for cleaning the
unit for proper operation.
4. Inadequate drain system.
Restriction in drain lines will cause ice in the bin to melt. If
using a gravity drain, make certain there are no kinks or re-
strictions in the drain lines. If using a drain pump, check the
inlet screen, discharge line, and vent line for any build-up or
restrictions.
5. Condenser fan air flow is restricted.
Make certain the grille in the front of the unit is free and
open for proper air circulation.
Unit continues to run
and produce ice.
1. Ice bin is not full.
The unit will automatically shut down when ice reaches the
sensing tube.
2. Ice bin is full.
The unit will automatically shut down when ice reaches the
sensing tube and has completed the harvest of the ice slab.
3. Room temperature is too warm.
Move the unit to an area where room temperature is below
90 degrees F.
4. Ice machine is not level.
Use a level to check the unit for level from side to side and
front to rear.
Grid-cutter is not cutting
the ice slab.
1. The selector switch is not in the “ON”
position.
Set the rocker switch on the grille of the ice machine to the
“ON” position.
2. The grid-cutter is not plugged into the
receptacle.
Remove the escutcheon panel and plug the grid-cutter into
the receptacle on the side of the cabinet liner.
3. Time to cut through the slab.
It can take up to 35 minutes to cut through a harvested ice
slab. This is normal operation.
