POSSIBLE CAUSE
Insufficient tightness
of the suction hose
The filter screen of
the non-return valve
of the sucking inlet is
blocked
The air can't be
released from the
pressure hose
because the water
outlet is closed
The waiting time
does not correspond
to the regulations
Excessive suction
head (>8m)
The non-return fails
to suck water
No power supplied
The ventilator hood
obscures rotation of
the vane
Fan blocked
Excessive suction
head (>8m)
The filter screen of
the non-return is
blocked
The suction water
level lowered too
much
Impurities have
reduced the effective
capacity of the pump
Over-load of the
electric motor due to
friction caused by
impurities entering
the motor

SOLUTION
Check the recommended and used pans
and components of the pump, e.g. joint of
the suction nose, joint of the pressure hose,
clamping ring, suction hose, etc., including
screw sealing strip made from Teflon or
hemp cord. The pump can work only when
well sealed
Clean the non-return of the sucking inlet and
the filter screen
When the pump starts sucking, open the
water outlet (e.g. the tap. sprinkling nozzle
etc.)
Fill the whole suction hose with water, or
recheck it at least 7 minutes after the pump
starts
Reduce the suction head
Check the water level of the well or the
water pool. If possible, increase the length
of the suction hose.
Check the power supply
Pull out the power plug, remove the
ventilator hood with a screwdriver, then
reinstall it again by slightly rotating the vane
and check to see if it rotates freely
Pull out the power plug, move the shaft with
the screwdriver through the ventilator hood.
If the shaft is blocked, send it to a service
center for inspection
Check the suction head
Clean the filter screen
Immerse the non-return in deep water
Wash the shell of the pump, the suction
hose and the outlet pressure hose with
pressurized water
Wash the shell of the pump with pressured
water
