Problem or Symptom Possible Cause Probable Correction
Machine is off
Bin is full, ice in cube port Use some ice
Power is off, check LEDs.
If all lights are out, check power supply, restore
power if off
Transformer is open
If all lights are out and there is power, check
transformer output for 24 vac
Unit has been switched off
or has finished a Clean
cycle, Off Light is glowing
Push and release Freeze button
Unit has Shut Down Check for Refrigeration or Water Error
Unit is off on a Water
Error
Water inlet valve
malfunction
Check water Light, if the Light blinks 2 times and
repeats, check the water inlet valve for proper
water flow.**
Water pump malfunction
Check that pump hose is attached and if pump is
plugged in and working.
Water level sensor may
have failed.
Check float stem, reset machine. If it will not
reset or gives another water error and everything
else is OK, replace the water level sensor.
Unit is off on a
Refrigeration Error
Low discharge or long
freeze cycle
Check refrigeration Light. If the Light is glowing,
there is a probable refrigeration problem or on
water cooled a water interruption
Harvest problem
Check refrigeration Light. If the Light blinks once
and repeats, look for a harvest problem.** This
also indicates that cubes were sensed by the bin
controls.
If the light blinks 2 times and repeats, check for a
harvest error - no cubes sensed.
High Discharge Temp
Check refrigeration Light. If the Light blinks 3
times and then repeats, check for a reason for
high discharge temperatures - such as a bad fan
motor or very hot ambient.
Unit does not go into
harvest - exceeds
maximum freeze time
Push and release Off button. Push and release
Freeze button. Check operation.
Push cube size float down and check operation.
Unit runs and both
Error Lights are ON Temperature sensors out
of range Replace the temperature sensor set (water and
discharge).
Same, but 1 light is on Reservoir temp. wrong Check water temp and sensor.
* Machine may be reset by pushing and releasing the Off button, then pushing and releasing the Freeze
button. ** See following pages
Service Diagnosis
Proper service diagnosis begins with observation, comparing the complaint to the operation of the unit. Ice
machine service diagnosis should proceed from water, to electrical and then to refrigeration.
