Solution
Use another device that works
to check the electricity outlet
and check the short-circuit swit-
ches
Check the short-circuit switches
and replace them if necessary
Cut the power supply and leave
to cool before re- starting the
pump. Make sure the pump and
motor have sufficient ventilation
space. Make sure that the pump
is not obstructed by dirt and the
motor can turn freely
You may have to change the
motor.
Blockage in the pump or in the
basket
Check the system to make sure
that the valves are in the correct
position for filtering, including
the inlet and outlet valves of the
pump.
Clean the filter
Start the pump (see starting pro-
cedure). Check to see there are
no suction air leaks in the pipes
or in the connections. Make sure
that the lid of the basket is well
closed and hermetically sealed.
Check there are no leaks under
the pump.
Make sure that the water level
is at least at the height of the
skimmer.
Make sure the pump or skim-
mer baskets are not full of dirt.
Make sure there is no blockage
at the inlet or outlet of the pump
or make sure there are no fo-
reign objects in the pump.
Cut-out the pump and loosen
the screws, check the alignment
and the condition of the wa-
ter-tight gaskets before tigh-
tening the screws, replace the
gaskets if necessary.
Make sure the lid correctly com-
presses the O-ring seal.
