SOLUTION
Power cut. Check the circuit breakers.

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.

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.
