TROUBLESHOOTING GUIDE
PROBLEM POSSIBLE CAUSE CORRECTION
Unit does not operate.
1. The unit is unplugged. Plug in the unit.
2. Breaker is tripped or fuse is blown.
Reset breaker or replace fuse. Check to make sure there is
not a short in the electrical circuit.
3. Ice machine selector switch is in the
“OFF” position.
Set the rocker switch on the grille of the ice machine to the
“ON” position.
Unit operates but does
not produce ice.
1. The unit has just been started and it
has been less than 6 hours.
Ice produced when the unit is initially started will melt off in
the bin. Ice will accumulate in the bin. In 6 hours, there can
be a few cubes in the bin. This is normal operation.
2. Typical ice production cycle can take
up to 1.5 hours. Initial start-up cycles
can be longer.
Check the unit in 24 hours for ice accumulation in the bin.
3. The selector switch is in the “OFF” or
“CLEAN” position.
Set the rocker switch on the grille of the ice machine to the
“ON” position.
4. No water in the reservoir.
Make sure that the reservoir drain plug is installed. Check
the water line to the unit to make sure it is on and that there
are no restrictions or kinks in the line. Check all filters to
make sure they are not restricted or plugged.
5. Distributor tube is restricted.
See “CLEANING YOUR ICE MACHINE” section for cleaning the
unit for proper operation.
6. Build-up of deposits on evaporator
plate.
See “CLEANING YOUR ICE MACHINE” section for cleaning the
unit for proper operation.
7. Condenser fan air flow is restricted.
Make certain the grille in the front of the unit is free and
open for proper air circulation.
8. Room and/or water temperature is
too warm.
Clean the grille with a vacuum and brush attachment. Move
the unit to an area where ambient temperature is below
90 degrees F. The unit should not be placed next to a heat
source such as an oven. Check for cold water connection.
9. Leaking drain valve.
Foreign material in the drain valve could cause it to leak. See
“CLEANING YOUR ICE MACHINE” section for cleaning the
unit.
10. 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.
11. Grid cutter is unplugged. Plug in the grid cutter so that ice slabs can be cut into cubes.
12. Circulation pump is unplugged.
Plug in the circulation pump so that water from the reservoir
can be circulated over the evaporation plate.

Electrocution Hazard - Never attempt to repair or perform main-
tenance on the unit until the main electrical power has been
disconnected. Turning the unit control “OFF” does not remove
electrical power from the units wiring.
