6.4 Troubleshooting guide
Certain operations must be carried
out by an authorized technician.
Problem Error codes Description Solution
High pressure protection
EE1
Pressure of the refrigeration
circuit is too high, or the water
flow is too low, or the coil is
obstructed or the air flow is
too weak.
Verify the high pressure switch
and the refrigeration circuit
pressure.
Verify the water or air flow.
Verify that the flow switch is
working correctly.
Verify the water inlet/outlet valve
openings.
Verify the by-pass setting.
Low pressure protection
EE2
Refrigeration circuit pressure
is too weak, or air flow is too
weak or the coil is obstructed.
Verify the low pressure switch
and the refrigeration circuit
pressure to determine if there
is a leak.
Clean the coil surface.
Verify the fan rotation speed.
Verify that there is free air flow
to the coil.
Flow sensor defect EE3
Water flow is insufficient or the
detector is in short-circuit or
defective.
Verify the water flow, verify the
filtration pump and the flow
detector to see if they have any
possible problems.
Does not start EE4
Problem with the connection to
PCB PROT2
Check the connection
Water inlet sensor defect.
PP1
The sensor is open or presents
a short-circuit.
Verify or replace the sensor.
Compressor sensor defect
PP2
The sensor is open or presents
a short-circuit.
Verify or replace the sensor.
De-icing sensor defect PP3
The sensor is open or presents
a short-circuit.
Verify or replace the sensor.
Aspiration sensor defect PP4
The sensor is open or presents
a short-circuit.
Verify or replace the sensor.
Exterior temperature sensor
defect
PP5
The sensor is open or presents
a short-circuit.
Verify or replace the sensor.
Safety mode PP7 Air temperature < 0°C: limit of operation
Communication problem 888
Problem with the LED
controller or the PCB
connection.
Verify the cable connection.
