6. POSSIBLE PROBLEMS, CAUSES AND SOLUTIONS.
PROBLEMS
– Water flow is
insufficient
– No air bubbles
emerge
– The pump does
not start
– The pump stops
running
– The pump does
not take in
water
– The motor
protection
switch triggers
– Noise
CAUSES
– Recirculation of water.
– Maximum flow of the pump is
small.
– 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.
– The capillary pipe (7) is
disconnected or has leaks.
– There is no electricity supply to
the installation.
– Incorrect pressure microswitch
operation.
– 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.
– 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.
– Condenser defective.
– Pump blocked by obstruction of
the turbine.
– Air is entering the equipment.
– Noise from bearings.
– Foreign bodies in the pump.
SOLUTIONS
– Comprobar el correcto montaje de los componentes
y en especial la presencia de la junta.
– Comprobar el correcto dimensionamiento de la
bomba.
– 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.
