TROUBLESHOOTING GUIDE
PROBLEM POSSIBLE CAUSE CORRECTION
Ice cubes are sticking
together.
1. Ice consumption is low.
Use the ice in the bin frequently. Ice will stick together if left
in insulated bin over long periods of time.
2. Room temperature is too warm.
Move the unit to an area where temperature is below 90
degrees F.
Ice level is too high.
1. The ice machine is not level.
Use a level to check the unit for level from side to side and
front to rear.
2. Room temperature is too warm.
Move the unit to an area where temperature is below 90
degrees F.
3. Ice deflector is not in place or secured
properly.
Check to see that the ice deflector is in place and secured
below the grid-cutter.
4. Bin level sensing tube needs adjusted.
You can adjust the bin level sensing tube by simply press-
ing directly down on the tube 5 inches from the front of the
tube to get a desired bin level.
Ice level is too low.
1. The ice machine is not level.
Use a level to check the unit for level from side to side and
front to rear.
2. Room temperature is too cold.
Move the unit to an area where temperature is above 55
degrees F.
3. The selector switch is not in the “ON”
position.
Set the rocker switch on the grille of the ice machine to the
“ON” position.
Water keeps backing up
into the ice bin (gravity
drain).
1. Inadequate drain system.
Restriction or improperly installed drain lines will cause
water to back up into the ice bin. Make certain there are no
kinks or restrictions in the drain lines. If necessary, consult a
qualified plumber.
2. Foreign material in ice bin drain.
Foreign material is restricting or blocking the ice bin drain
located at the right rear corner of the ice bin. The drain will
need to be cleared.
Water keeps backing up
into the ice bin (drain
pump).
1. Drain pump tubing kinked or restrict-
ed.
Check inlet, discharge, and vent line tubing for any kinks or
restrictions and repair as necessary.
2. Inlet screen to the drain pump is
restricted or blocked.
Check the inlet screen to the drain pump.
3. Drain pump and/or the ice machine
are not level.
Check and level, if necessary, the drain pump as well as the
ice machine.
The drain pump cycles
on and off erratically.
1. Vent line to the drain pump is re-
stricted or kinked.
Check the vent line for any restrictions or kinks and repair as
necessary.
2. Discharge line is restricted or kinked.
Check the discharge line and connection to the desired drain
for any restrictions or kinks and repair as necessary.
3. The drain pump is not level.
The drain pump must be level. Check for level on the top of
the drain pump case and adjust the tubing or use shims to
level.
