Code Display Alarms Diagnosis User Action
E1
ALARM T1 Input Open or shortened probe Replace probe
E2
ALARM T2 Input Open or shortened probe Replace probe
E3
ALARM T3 Input Open or shortened probe Replace probe
E4
ALARM T4 Input Open or shortened probe Replace probe
E6
ALARM High Pressure Discharge pressure has exceeded
370 psi
Clean air filter; Clean condenser coil; verify
condenser fan is operating
E7
ALARM HP1 Input Loss of signal/High pressure
transducer
Check the wire connection between the
transducer and the board. Replace transducer
E8
ALARM LP1 Input Loss of signal/Low pressure
transducer
Check the wire connection between the
transducer and the board. Replace transducer
E9
ALARM Water Level Sensor Input Loss of signal Verify tubing connecting sensor to the board
is not damaged, verify the pressure sensing
chip on the control board is making good
contact.
E11 ALARM Low Temperature T1 in
Freeze
T1 probe fell below -10˚ within the
first 2 min of the freeze cycle
Check probe resistance/location (evaporator
outlet); verify pump motor is operating; check
to see that previous ice sheet fell and is not
on the evaporator coil.
E12 ALARM High Temperature T1 Evaporator outlet temp exceeded
113˚F (45˚C)
Verify unit is being supplied by cold water;
check ambient temps. Ohm out probe.
E13 ALARM Low Temperature T1 Evaporator outlet temp fell below
-20˚F (-29˚C)
Ohm out probe; verify evaporator outlet
temperature; verify pump motor is operating
during freeze cycle; verify unit has water.
E14 ALARM High Temperature T2 Ambient temp exceeded 130˚F(54˚C) Verify ambient temperatures; ohm out probe;
verify condenser motor is running during
freeze cycle.
E15 ALARM Low Temperature T2 Ambient temp fell below 33˚F (0.5˚C) Verify ambient temperature; ohm out probe.
E16 ALARM High Temperature T3 Water trough temperature exceeded
113˚F (45˚C)
Verify water in trough temperature; ohm out
probe.
E17 ALARM Low Temperature T3 Water trough temperature fell below
25˚F (-4˚C)
Verify water trough temperature; ohm out
probe.
E18 ALARM High Temperature T4 Incoming water temp exceeded
124˚F (51˚C)
Check water supply temps; ohm out probe.
E19 ALARM Low Temperature T4 Incoming water temp fell below
33˚F (0.5˚C)
Check water supply temps; ohm out probe.
E20
ALARM High Pressure on HP1 Head pressures greater than 320-360
psi. (Depending on Model)
Clean air filter; clean condenser coil; verify
condenser fan operates correctly.
E22
ALARM Long Freeze Time Freeze cycle exceeded 40 min Verify compressor is running; check High and
Low side pressures.
E23
ALARM Calculation Error -
Negative Value
Water level in sump during freeze
cycle fell below the differential
Verify water is not leaking near evaporator
cover and the harvest flap; check if water
leaks from the drain valve.
E24
ALARM Long Fill Time Sump tank did not fill within 30 min Verify unit has water; check incoming water
filter; check inlet water valve.
