11 TROUBLE SHOOTING
PROBLEM
The electric motor is running
but the pump does not suck
water
The electromotor cannot run
Insufficient water flow-out
The heat-sensitive switch
cannot switch-off the pump
The switch of the pump is
always OFF or ON
Frequent switching ON/OFF of
the pump switch (when used
for household water supply
system)

POSSIBLE CAUSE
1. After the pump starts, the pump body
does not fill with water
2. Insufficient tightness of the suction
hose
3. The filter screen of the non-return
valve of the sucking inlet is blocked
4. The air can't be released from the
pressure hose because the water outlet
is closed
5. The waiting time does not correspond
to the regulations
6. Excessive suction head (>8m)
7. The non-return fails to suck water
1. No power supplied
2. The ventilator hood obscures rotation
of the vane
3. Fan blocked
1. Excessive suction head (>8m)
2. The filter screen of the non-return is
blocked
3. The suction water level lowered too
much
4. Impurities have reduced the effective
capacity of the pump
1. Over-load of the electric motor due to
friction caused by impurities entering the
motor
1. No non-return valve installed on the
suction hose
1. Rupture of the rubber envelope in the
pressure tank
2. No compressed air in the container

SOLUTION
1. Fill the pump with water
2. 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
3. Clean the non-return of the sucking
inlet and the filter screen
4. When the pump starts sucking, open
the water outlet (e.g. the tap. sprinkling
nozzle etc.)
5. Fill the whole suction hose with
water, or recheck it at least 7 minutes
after the pump starts
6. Reduce the suction head
7. Check the water level of the well or
the water pool. If possible, increase the
length of the suction hose.
1. Check the power supply
2. 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
3. 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
1. Check the suction head
2. Clean the filter screen
3. Immerse the non-return in deep
water
4. Wash the shell of the pump, the
suction hose and the outlet pressure
hose with pressurized water
1. Wash the shell of the pump with
pressured water
1. Check to see if a valve is installed
on the suction hose
1. Replace the rubber envelope or the
container
2- Use an adequate valve and conned
this with a compressed air supply at
1.8 bar, and fill the container with air
