10 TROUBLE SHOOTING

PROBLEM

POSSIBLE CAUSE

SOLUTION

The electric motor is
running but the pump
does not suck water

1. After the pump starts, the pump body
does not fill with water

1. Fill the pump with water

2. Insufficient tightness of the suction
hose

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. The filter screen of the non-return
valve of the sucking inlet is blocked

3. Clean the non-return of the sucking
inlet and the filter screen

4. The air can't be released from the
pressure hose because the water outlet
is closed

4. When the pump starts sucking, open
the water outlet (e.g. the tap. sprinkling
nozzle etc.)

5. The waiting time does not
correspond to the regulations

5. Fill the whole suction hose with water,
or recheck it at least 7 minutes after the
pump starts

6. Excessive suction head (>8m)

6. Reduce the suction head

7. The non-return fails to suck water

7. Check the water level of the well or the
water pool. If possible, increase the
length of the suction hose.

The electromotor
cannot run

1. No power supplied

1. Check the power supply

2. The ventilator hood obscures rotation
of the vane

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. Fan blocked

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

Insufficient water flow-
out

1. Excessive suction head (>8m)

1. Check the suction head

2. The filter screen of the non-return is
blocked

2. Clean the filter screen

3. The suction water level lowered too
much

3. Immerse the non-return in deep water

4. Impurities have reduced the effective
capacity of the pump

4. Wash the shell of the pump, the suction
hose and the outlet pressure hose with
pressurized water

The heat-sensitive
switch cannot switch-off
the pump

1. Over-load of the electric motor due to
friction caused by impurities entering
the motor

1. Wash the shell of the pump with
pressured water

The switch of the pump
is always OFF or ON

1. No non-return valve installed on the
suction hose

1. Check to see if a valve is installed on
the suction hose

Frequent switching
ON/OFF of the pump
switch (when used for
household water supply
system)

1. Rupture of the rubber envelope in
the pressure tank

1. Replace the rubber envelope or the
container

2. No compressed air in 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
