Correction
Ice is not clear.
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.
Softened water supply.
Make certain the water line is not connected
to the water softener.
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 and has run over
a 48 hour period but there
is little ice accumulation
in bin.
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.
Distributor tube is restricted.
See “Cleaning Your Ice Machine” section for cleaning the
unit for proper operation.
Build-up of deposits on evapora-
tor plate.
See “Cleaning Your Ice Machine” section for cleaning the
unit for proper operation.
Inadequate drain system.
Restriction in drain lines will cause ice in bin to melt. 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 re-
stricted.
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.
Faulty drain pump installation or
faulty drain pump.
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.
Unit continues to run and
produce ice.
Ice bin is not full.
The unit will automatically shut down when ice reaches
the sensing tube.
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.
Ice machine is not level.
Use a level to check the unit for level from side-to-side
and front-to-back.
Room temperature is too warm.
Move the unit to an area where room temperature is
below 90 degrees F.
Bin thermistor is out-of-range.
Check bin thermistor resistance value with that of “Resis-
tance versus Temperature Chart” page 27, Thermistors.
Cutter-grid is not cutting
the ice slab.
The selector switch is not in the
“ON” position.
Set the rocker switch on the grille of the ice machine to
the “ON” position.
The grid-cutter is not plugged
into the receptacle.
Remove the escutcheon panel and plug cutter-grid into
the receptacle on the side of the line.
Time to cut through the slab.
It can take up to 35 minutes to cut through a harvested
ice slab. This is normal operation.
Ice cubes are sticking
together.
Ice consumption is low.
Use the ice in the bin frequently. Ice will stick together if
left in an insulated bin over long periods of time.
Room temperature is too warm.
Move the unit to an area where temperature
is below 90 degrees F.
