11 TROUBLE SHOOTING
PROBLEM
POSSIBLE CAUSE
SOLUTION
The electric motor is
running but the pump
does not suck water
After the pump
starts, the pump
body does not fill
with water
Fill the pump with water
Insufficient tightness
of the suction hose
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
The filter screen of
the non-return valve
of the sucking inlet is
blocked
Clean the non-return of the sucking inlet and
the filter screen
The air can't be
released from the
pressure hose
because the water
outlet is closed
When the pump starts sucking, open the
water outlet (e.g. the tap. sprinkling nozzle
etc.)
The waiting time
does not correspond
to the regulations
Fill the whole suction hose with water, or
recheck it at least 7 minutes after the pump
starts
Excessive suction
head (>8m)
Reduce the suction head
The non-return fails
to suck water
Check the water level of the well or the
water pool. If possible, increase the length
of the suction hose.
The electromotor
cannot run
No power supplied
Check the power supply
The ventilator hood
obscures rotation of
the vane
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
Fan blocked
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
Insufficient water flow-
out
Excessive suction
head (>8m)
Check the suction head
The filter screen of
the non-return is
blocked
Clean the filter screen
The suction water
level lowered too
much
Immerse the non-return in deep water
