SOLUTION
•
Power cut. Check the circuit breakers.
•
Check the connection between the power cable and the motor' s terminals.
•
Check that the motor shaft is turning freely. Check that there is no debris
in the pre-filter basket.
•
If any debris still remains, remove the pump to access the turbine.
•
Check the position and watertightness of the valves in the hydraulic circuit.
•
Air is trapped in the circuit. Bleed the hydraulic circuit (drainage on the filter).
•
The pool' s water level is too low, so the circuit is sucking in air. Fill the pool.
•
The pre-filter lid is defective. Check the state of the seal and that the lid
is watertight.
•
The pre-filter basket is full of debris. Clean it.
•
Air leak in the circuit. Check all of the tightening torques.
•
The turbine and pump diffuser are blocked or worn. Replace them.
•
The diffuser's seal is worn. Replace it.
•
Reverse rotation of the motor (only on three-phase pumps). Check the
connections of pump's terminal blocks.
•
The filter is blocked up. Wash the filter.
•
Check the position of the valves in the hydraulic circuit.
•
Air leak or cavitation in the suction piping. Check the position of the
valves and adjust them whenever necessary.
•
Pump badly placed on the ground. Check that it is on a flat, hard,
horizontal surface. Use anti vibration pads whenever necessary.
•
There is a foreign body in the pre-filter basket.
•
There is a foreign body in the body of the pump. The pump must be
removed and taken for servicing.
