E19 Ice Thickness Probe Fault
The monitored Frequencies is out of the appropriate range
(probe unplugged or problem with microphone).
E20 Water System Fault
Any of the following:
1. Sensing high water probe and not low water probe.
2. Evaporator outlet temperature is less than -10°F 6.5
to 7.5 minutes in freeze cycle.
3. Low water probe is satisfied at the end of harvest.
4. Low or high water probe is satisfied at end of freeze
cycle.
E21 T1 Temperature Sensor Issue
During Pre-chill the thermistor had an average value
reading outside the valid range.
E22 T2 Temperature Sensor Issue
During Pre-chill the thermistor had an average value
reading outside the valid range.
E23 T3 Temperature Sensor Issue
During Pre-chill the thermistor had an average value
reading outside the valid range.
E24 T4 Temperature Sensor Issue
During Pre-chill the thermistor had an average value
reading outside the valid range.
E25 Bin Level Probe Low Sensor Fault
The thermistor had an average value reading outside of
the valid range for 10 continuous minutes.
