What to do before calling for service
Reasons the machine might shut itself off:
•
Lack of water.
•
Freeze cycle takes too long.
•
Harvest cycle takes too long.
•
High discharge temperature.
•
Controller self test failure.
Check the following:
1. Has the water supply to the ice machine or
building been shut off? If yes, the ice machine will
automatically restart within 25 minutes after water
begins to flow to it.
2. Has power been shut off to the ice machine? If
yes, the ice machine will automatically restart when
power is restored.
3. Has someone shut the water off to a water
cooled unit? If yes, after the water supply has been
restored the ice machine may need to be manually
reset.
4. Is the curtain open because some ice is stuck
under it? If so, remove the ice and the machine
should start in a few minutes.
Note: Curtain can be removed & replaced anytime
the machine is in a standby mode or when it is in a
freeze cycle. However, removal of the curtain
during freeze will result in water flowing into the
bin. Removal of the curtain during harvest
terminates harvest at that point and, if left off, will
result in the machine shutting off.

•
Push and release the On button.
