11 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
