Part Number 80-1230-9 10/10 161
WATER LEVEL PROBES
QF0400/QC0700/QF0800/QF2200/QF2300
FUNCTION
The water level probe protects the compressor if water
is not detected.
Water contacting the probes will complete the circuit
and energize the Water Level Probe light.
There are two water level probes; one probe is
connected to the circuit board and one probe is
connected to the ice machine ground.
Water level probe operation can be determined by
watching the Water Level Probe light. The Water Level
Probe light is on when water contacts the probe, and
off when no water is in contact with the probe. The Water
Level Probe light functions any time power is applied to
the ice machine, regardless of toggle switch position.
During the Water Fill and Freeze cycle, the water level
probe monitors the water level. The water float valve
maintains the correct water level. If the water level is
incorrect, refer to “Water Float Valve.”
FAILURE MODES
Water Level Probe Open or Disconnected
(Ice machine will not start compressor.)
Performs initial start-up procedure. Ninety seconds
after ice machine enters Water Fill (1B), the ice
machine will initiate an Automatic Shut-Off cycle, flash
the Water Level Probe light and remain off for
60 minutes. (Refer to “No Water” SafeGuard for
additional information.)
