Indigo NXT Ice Machine Troubleshooting Tips
When an Alert / E Log is triggered;
• Alerts shows up on the Home screen
as an Alert Icon.
•Alerts are also kept track of on what
we call “Alert Log”.
•Alert Log list time stamp of last Alert
along with count of how many times it
has tripped. Still visible in the Service
Menu, even if the Alert was cleared by
the end-user from the Home Screen.

E01
Long Freeze
Long Freeze
3 consecutive 35 Minute Freeze cycle, shut down

Power Loss
Power Supply (Event
Log only - No Alarm)
When power is interrupted to the ice machine the control board will log the event in the ELOG and stamp the loss of
power on power-up.

E05
HPC Fault
High Pressure Cutout
(HPC)
The high pressure cutout switch (HPCO) opened.
Alert will show after 3 trips in 4 hours.
E06 Spare
E07
Starving TXV
Starving Evaporator for
single TXV or low on
charge
When harvest is initiated by the ITP: the board compares the last one minute of Freeze average temperature
difference between the inlet (T3) and the outlet (T4). If the difference between the outlet minus the inlet is greater
than 12°F E07 is recorded.
E08
TXV Fault
TXV malfunction in dual
circuit/ single evaps
(TXV Fault)
When harvest is initiated by the ITP: the board compares the last one minute of Freeze average temperature
difference between the outlet (T3) and the outlet (T4). If the difference between the outlet minus the inlet is greater
than 12°F E07 is recorded.
E09
Flood Evap 1
Flooding evaporator for
single circuit single
evaporator (flooding
evap)
Discharged line temp. is monitored in 6 second increments for the first 6 min. of freeze. Each minute is averaged
and the highest average is stored as T2max(3). During the last 6 seconds of pre chill the liquid line temp exiting the
condenser is averaged

Flood Evap 2
Flooding evaporator for
dual TXV dual circuit /
single evaporator
(Flooding Evap)
Discharged line temp. is monitored in 6 second increments for the first 6 min. of freeze. Each minute is averaged
and the highest average is stored as T2max(3). During the last 6 seconds of pre chill the liquid line temp exiting the
condenser is averaged
E11
Refig Fault
(Air, Water only)
Refrigeration System
(Refrig Fault)
If the compressor discharge temperature has not increased by at least 10 F, and the evaporator temperature has
not decreased by at least 10 F from the Refrigeration Start up or start of prechill to Two Minutes into the Freeze
cycle.
