5. Troubleshooting
5.1 Error codes
Number of
flashes
Malfunction
Possible causes
Solutions
1
User interface is
defective
• The user interface resets itself
constantly
•
Check the electrical connections inside
the user interface housing.
•
Replace the motor - interface assembly
if necessary.
2
Network sub-
voltage
•
The network voltage has fallen
below 180VCA.
•
The interface will reset when the
voltage rises over 209VCA again for at
least 6 seconds
3
Temperature
• Motor temperature too high
(+100°C)
•
Motor temperature too low
(-20°C)
•
Wait until normal temperature conditions
return and restart the pump.
4
Surge activation
•
The surge protection has been
activated
•
Check the electrical supply.
•
Restart the pump.
5
Network
overvoltage
•
The voltage exceeds 269VCA
•
The interface will reset when the
voltage returns to a normal value.
6
Motor shaft jammed
• Motor start-up impossible
• The motor has stopped
•
Break the pump circuit and check
that no debris is blocking the turbine
(remove the pre-filter screen).
• Check that there is no debris blocking
the rear fan.
7
Automatic
verification
•
At least one of the automatic
tests failed on start-up or
during operation
•
Break the pump circuit then reconnect it
to reset it.
8
Motor fault
• At least one of the phases is
disconnected
•
Check the electrical connections inside
the user interface housing.
5.2 Equipment malfunction
Malfunction
Possible causes
Solutions
The water does not
circulate correctly
•
Pre-filter screen and/or filter
blocked with dirt
•
Valves incorrectly set
•
Clean the pre-filter screen and/or the filter
• Set the valves
Air bubbles are present
in the pre-filter screen
• Air blocked in the circuit
•
Swimming pool water level too
low
•
Incorrect pre-filter cover seal
•
Bleed the circuit
•
Check the water level and top up if necessary
•
Check that the cover and its seal are water-tight
There are air intakes
•
Couplings incorrectly tightened
•
Coupling seals incorrectly
positioned or damaged
•
Retighten the couplings
• Change the seals
There is no air in the
circuit but the pressure
is low
• Debris jammed in the pump
•
Remove the debris by hand by opening the cover and
removing the pre-filter screen
•
If debris remains, you must dismantle the pump to
access the turbine
•
Caution: these tasks must be carried out by a qualified
technician
There is no debris in the
pump but the pressure
is low
• The turbine and the pump
diffuser are worn
• Electrical problem
•
Seal worn
•
Have the turbine and the diffuser replaced by a
qualified technician
•
Have the electrical installation checked by a qualified
technician
•
Replace the seal
There is a water leak
between the motor and
the pump body
• Mechanical lining damaged or
defective
•
Replace the mechanical lining
•
Caution: these tasks must be carried out by a qualified
technician
The pump heats up and
switches off sometimes
•
Poor air circulation around the
motor
•
Poor electrical connections
•
Current variations too high
•
Check that the motor is ventilated enough to cool
down
•
Check the electrical connections
•
Have the electrical network checked by a qualified
technician
The pump does not
start
•
No electrical supply to the pump
• The user interface cable is
damaged
•
The "error" light flashes
•
Check the electrical connections
•
Check the condition of the user interface cable
• See § “5.1 Error codes”
There is no damage to
the user interface
•
Cables damaged or poorly
connected in the user interface
housing
•
Check the condition of the user interface cables
