Problem or Symptom Possible Cause Probable Correction
Low capacity Dirty condenser Clean condenser
Air temperature intake to condenser
very high Re-orient condenser to avoid hot air
intake
Water temperature intake to ice making
section very high Check for hot water supply to ice
machine due to mal-functioning or
non-existent hot water check valve at
dishwashing sink
Ice broken up and stuck between
reservoir and curtain, happens almost
every cycle Ice thickness set too thin
Ice very uneven, check superheat
Slow harvest, check headmaster
Storage bin or dispenser not holding ice
properly Check drains for water flow from ice
machine (separate to correct) or
restriction
High volume of drinks dispensed, cold
plate melting ice Suggest pre-cooler for water supply to
cold plate
Vapor inlet valve leaks through slightly
during the freeze cycle Check valve body for similar
temperatures on inlet and outlet, the
outlet should be colder and frost
develops on the tubes to the
evaporators
Exceeding maximum freeze time,
compressor unit trips on high discharge
temp Check condenser bypass valve
Poor ice formation - very cloudy
and misshapen Dirty water system Clean the water distributor to remove
built up mineral scale
Low refrigerant charge. Add several pounds of refrigerant to
check. If low on charge, locate leak.
Recover refrigerant, repair leak, replace
drier, evacuate to 300 microns and
weigh in the nameplate charge.
Whistling noise at CP unit during
harvest By pass and liquid inlet valve coils not
getting power Check harness
