Ice Quality

Odor, grey color, or off taste in the ice
Is there mineral scale build up on the evaporator
plate? The ice machine needs cleaning. See "Cleaning
the Ice Machine".
Is there a high mineral content in the water? The water
may need to be filtered.
Are food items being stored in the ice bin? Remove
food from the ice bin.
Unpleasant Odors may require the use of a charcoal filter
on the water supply line.
Clumps of ice
Are there clumps of ice in the bin? If the ice isn't used
on a regular basis it will melt and form into clumps. Break
up the ice clumps with the ice scoop.
Ice cubes are too small
Is there low ice consumption? Ice is slowly melting in
the ice bin which will affect the size of the cubes. This is
normal. When the ice bin needs to be replenished, cubes
will return to the regular size.
Is the ice slab releasing? Clean the evaporator. See
"Cleaning the Ice Machine" on page 15 and run "Clean
Mode" before calling for service.
Is the distributor tube restricted? Check the water line
to the ice machine to make sure there are no restrictions
or kinks in the line. Check all filters to make sure they are
not restricted. Check that the water flows evenly out of the
distributor tube, if not, clean the ice machine. See "Clean-
ing the Ice Machine".

Plumbing Problems

Is the ice machine draining properly? Check that there
are no kinks or restrictions in the drain lines; this can
cause water to back up in the ice bin. Check that foreign
material is not blocking the ice bin drain located at the
right rear corner of the ice bin. Check the drain pump
discharge and vent line for any restrictions or kinks. Check
that the drain pump is level.
NOTE
If there are plumbing issues outside of the ice machine,
they cannot be repaired by the service technician. A quali-
fied plumber will have to be called.
TROUBLESHOOTING THE ICE MACHINE
Troubleshooting the Drain Pump
NOTE
If the drain pump reservoir (not the ice machine bin)
reaches overfill condition, the power to the ice machine will
be shut off.
If the ice machine is not working, check the following:
• Make sure there is power at the receptacle.
• Make sure the ice machine is turned on.
• Make sure the ice bin is not full.
Then check the drain pump:
The pump does not run:
• Make sure the pump is plugged in and there is power
to the receptacle.
• Check the inlet to the drain pump for debris and clean
as needed. Remove clamps and inlet tube from drain
pump to check for and remove debris.
• Make certain the vent line is free of kinks/sharp bends
or restrictions.
• Make certain there is enough water to activate the
drain pump. It will take at least one (1) quart (.95 liters)
of water to activate the drain pump.
The pump runs, but no water is pumped out:
• Check that the vent is clear and free of restrictions.
• Check the discharge line to make certain there are no
restrictions.
• Make sure that the discharge tubing has not exceeded
the maximum lift for the corresponding horizontal run.
See Table A on page 6.
The pump runs and then quickly turns off repeatedly:
• Check to make certain the drain pump is level.
• Check that the vent is clear and free of restrictions.
