Defrost valve opens
during 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 water
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 water 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 dimples.
Reduce the water level until ice
cubes are produced with small
dimples.
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
residue from the water plate
thoroughly.
Water valve will not
close. Potable water
level continues to
rise after contacting
the tip of the high
water level probe,
during the fill cycle.
No voltage measured at water valve
coil. Water valve remains open
because of water supply problem.
