6. POSSIBLE PROBLEMS, CAUSES AND SOLUTIONS.

PROBLEMS
– Water flow is – Recirculation of water.
insufficient
– Maximum flow of the pump is small.
– No air bubbles – The filter (9) fitted in the hose is
emerge dirty and air does not pass.
– Air passage at the front plate (6) is
obstructed by insects or foreign
bodies.
– The air regulator is closed.
– The pump does not – The capillary pipe (7) is
start disconnected or has leaks.
– There is no electricity supply to the
installation.
– Incorrect pressure microswitch
operation.
– The pump stops – The pump thermal cut-out switch
running activates.
– The motor-protection cut-out on the
panel throws.
– The installation's differential circuit-
breaker switch triggers
– Electrical connection failure.
– The pump does not – The pump is not primed.
take in water – The suction pipes are not sealed
and the pump takes in air.
– The suction piping is long and the
pump is higher than the swimming
pool level.
– Pool water level insufficient and air
is being taken in.
– The motor – Condenser defective.
protection switch
triggers – Pump blocked by obstruction of the
turbine.
– Noise. – Air is entering the equipment.
– Noise from bearings.
– Foreign bodies in the pump.
CAUSES
– Check correct fitting of components, and particularly that the gasket has been
fitted.
– Check correct pump dimensioning.
– Clean the filter (9) and remove impurities.
– Clean and ensure that air is passing to the discharge pipe.
– When the air regulator is opened bubbles should emerge.
– Check that the capillary pipe (7) is correctly installed.
– Wait for electricity supply to be restored.
– Check electrical continuity at the pressure switch by activating and deactivating
the button.
– Check that the premises is correctly ventilated and that air passage of the pump
fan is not obstructed.
– Check that the pump ampere rating is less than or equal to the cut-out trigger
rating.
– Check for insulation or shunt-off faults.
– Check that electrical connections are correct.
– Fill the suction body up to the level of the suction connection.
– Repair leaks.
– Bleed air from the pump.
– A check valve without spring pressure must be mounted in the suction pipes to
prevent water draining during suction.
– Raise the water level of the pool to at least 10 cm above the plate.
– Check that the condenser is of the correct capacity.
– Replace if faulty.
– The motor shaft must rotate slightly.
– If not, the pump must be repaired by the technical service centre.
– Stop leaks.
– The pump must be repaired by the technical service centre.
– Remove them as explained in the pump maintenance manual.
