TROUBLE SHOOTING
Problem
Possible Cause
Solution
Defrost valve opens
during water fill.
Slow water fill.
The water supply pressure must be a
minimum of 5 PSI (34 KPA) dynamic at
the water valve. Be sure that the supply
line is of adequate size. This is especially
important for liquid cooled models where
the potable water and condenser coolant
water are supplied by the same water
line. Check for restrictions in the wa
-
ter supply line including clogged filters.
Check the water line strainer and clean it
if needed.
Cold potable water supply.
This is normal operation of the unit, if the
water supply is too cold. Very cold water
will not rinse the ice residue from the wa-
ter plate, causing it to build up and affect
normal operation.
Ice remains attached to
the water plate surface
at the end of defrost.
Ice frozen into the water plate surface.
Thick web between ice cubes.
Adjust web thickness to specifications.
Ice frozen into the water plate surface.
Cubes are fully formed without small dim-
ples.
Reduce the water level until ice cubes are
produced with small dimples.
Over-freezing
Be sure that the control stream does
not go over the dam for longer than 15
seconds.
Cold potable water supply.
Very cold water will not rinse the ice resi-
due from the water plate thoroughly.
