Possible causes
1) The pump body (A4) was not filled with water before start-up.
2) Suction hose not airtight.
3) Foot valve suction strainer obstructed.
4) Delivery side air unable to escape because suction point
is closed.
5) Not enough time allowed.
6) Excessive suction lift.
7) Suction hose not immersed in water.
1) No mains power.
1) Suction lift and/or head excessive.
2) Foot valve suction strainer obstructed.
3) Water level in suction point drops too fast.
4) The appliance's flow rate is being reduced by soil in the water.
1) Motor overloaded due to friction between dirt particles and
impeller.
Dry operation or flow of water insufficient.
2) Dry operation.
1) No check valve on suction hose, water flowing back from
suction hose.
2) Rubber diaphragm in tank (A10) faulty.
3) No air pressure in tank.
4) Delivery side not airtight.
1) The switch-off pressure set for the pressure switch is too high.
2) Delivery side not airtight.
1) Fill the pump body (A4, see point 6.3).
2) Check that the recommended accessories were used. Check that
the suction hose is airtight, use Teflon tape on the threads.
3) Clean foot valve and suction strainer.
4) During priming, open the suction points (water supply tap, water
hoses).
5) Completely fill the suction hose with water and wait up to 7
minutes after the appliance is started.
6) Reduce the suction lift (max. 8 m).
7) Check the water level in the well or cistern and lengthen the
suction hose if possible .
1) Check the voltage, connect the plug (A12).
1) Excessive suction lift and head and external components all
reduce the flow rate! This is not a malfunction.
2) Clean the suction strainer.
3) Immerse the foot valve in a greater depth of water.
4) Clean the pump body (A4) by directing a jet of water in through
the suction fitting (A1) and delivery fitting (A2), and if necessary
have the appliance checked by the Service Centre. Use a pre-filter
if the appliance does not have an integral pre-filter (A1 b).
1) Clean the inside of the pump body (A4) by directing a jet of water
in through the delivery fitting (A2), leave the thermostat to cool for
about 1 h, and if necessary have the appliance checked by the
Service Centre.
2) Check that there is water present, leave the thermostat to cool
for about 1 h, and if necessary have the appliance checked by the
Service Centre.
1) Check whether a foot or intermediate valve is installed on the
suction side.
2) Replace the rubber diaphragm or the tank. Contact the Service
Centre.
3) Fill the tank (A10) with air by means of the relative valve (A9) to
a pressure of 1.5 bar (see Maintenance).
4) Seal the delivery side to render it airtight, check that the system
is airtight.
1) Notify the Service Centre and have the switch-off pressure
adjusted.
2) Seal the delivery side to render it airtight, use Teflon tape on
the threads.
