6. POSSIBLE PROBLEMS, CAUSES AND SOLUTIONS
PROBLEMS
CAUSES
SOLUTIONS
– Water flow is
insufficient
– Recirculation of water.
– Maximum flow of the pump is small.
– Test the right components assembly and
especially the joint.
– Verify the right pump sizing.
– No air bubbles
emerge
– The filter (9) fitted in the hose is 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.
– 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.
– The pump does
not start
– The capillary pipe (7) is disconnected or
has leaks.
– There is no electricity supply to the
installation.
– Incorrect pressure microswitch operation.
– 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.
– The pump stops
running
– The pump thermal cut-out switch
activates.
– The motor-protection cut-out on the panel
throws.
– The installation’s differential circuitbreaker
switch triggers.
– Electrical connection failure.
– 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.
– The pump does
not take in water
– The pump is not primed.
– 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.
– 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.
– The motor
protection switch
triggers
– Condenser defective.
– Pump blocked by obstruction of the
turbine.
– 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.
– Noise
– Air is entering the equipment.
– Noise from bearings.
– Foreign bodies in the pump.
– Stop leaks.
– The pump must be repaired by the
technical service centre.
– Remove them as explained in the pump
maintenance manual.
