5.1 I Appliance behaviour
The pump does not
start / the motor does
not turn.
•
Filtrati on outside of a scheduled operati ng range (“Auto” mode). Check the fi ltrati on
clock setti ngs.
•
Electric power cut. Check the circuit breaker(s).
•
Check the connecti on between the power cable and the motor terminals.
•
Check the user interface cable.
•
Incorrect confi gurati on of the pump address; check the positi on of the switches (see
§ "2.4 I Connecti ng the user interface (depending on the model)").
•
Check that the motor shaft rotates freely. Ensure that there is no debris in the pre-fi lter
strainer.
•
If debris remains, remove the pump to access the turbine.
The pump doesn’t
prime / air can be seen in
the pre-fi lter strainer.
•
Check the positi on of all valves in the hydraulic circuit.
•
Air is stuck in the circuit, drain the hydraulic circuit (bleed screw on the fi lter).
•
The pool’s water level is too low, air is being sucked into the circuit; fi ll the pool.
•
The gasket of the pre-fi lter strainer lid is defecti ve, check the conditi on of the gasket
and the correct air-ti ghtness of the lid.
Low fl ow rate / low fi lter
pressure
•
Pre-fi lter strainer full of debris: clean.
•
Air leak in the circuit. Check all ti ghtening torques.
•
The turbine and the pump diff user are blocked or worn, replace.
•
The diff user seal is worn, replace.
•
Reverse motor rotati on (three-phase models only). Check the electrical connecti on
at the pump terminals.
Low fl ow rate / high fi lter
pressure
•
The fi lter is clogged. Wash the fi lter (or the cartridge depending on the case).
•
Check the positi on of all valves in the hydraulic circuit.
Pump making a lot of
noise
•
Air leak or cavitati on in the sucti on piping. Check the positi on of the valves and adjust
where necessary.
•
Pump incorrectly positi oned on the ground. Check that it is resti ng in a fl at positi on on
a hard, horizontal ground. Use anti -vibrati on studs where necessary.
•
A foreign body is present in the pre-fi lter strainer.
•
A foreign body is present in the pump body (in this case, the pump must be
removed).
Leak between the pump
body and the motor
•
The mechanical lining is damaged or defecti ve, replace
The pump heats up and
switches off
•
The motor is overheati ng due to too litt le venti lati on. Check that there is enough clear
space around the motor.
•
There is an electrical fault. Check the power connecti ons and check the mains
voltage, which must not vary.
There is nothing on the
user interface or the
external controller display
•
Incorrect confi gurati on of the pump address; check the positi on of the switches (see
§ "2.4 I Connecti ng the user interface (depending on the model)").
•
Check the user interface cable.
The user interface
displays 'PUMP NOT
CONNECTED"
•
Check the user interface cable.
•
Incorrect confi gurati on of the pump address; check the positi on of the switches (see
§ "2.4 I Connecti ng the user interface (depending on the model)").
