E09 Flooding Evaporator Fault Single Evaporator, Single
Circuit
Average compressor discharge line temperature during
the first 6 minutes of the freeze cycle (T2) compared to the
average of the Prechill (T1) +50°F is less than 1.05°F.
E10 Flooding Evaporator Fault Dual TXV, Dual Circuit
Average compressor discharge line temperature during
the first 6 minutes of the freeze cycle (T2) compared to the
average of the Prechill (T1) +50°F is less than 1.05°F.
E11 Refrigeration Fault
The compressor discharge temperature did not increase
by at least 10° F, and the evaporator temperature did not
decreased by at least 10° F - Measured from Refrigeration
Start up or Prechill until 2 minutes into the Freeze cycle.
E12 Curtain Switch Fault Open more than 24 hours
The ice machine is set to ice making and remains in bin
full condition for more than 24 hours. The curtain switch is
open or curtain is off.
