Cause
Failure on the suction
side, pressure cannot
build up
Flow rate very low -> the
dry run protection has
switched off the pump.
Failure in the pressure
line, the pump frequently
switches on and off as a
result of leakage.
Error on delivery side.
The pressure is too low
after shutdown of the
pump, the appliance
starts again immediately
and thus switches on
and off frequently.
The appliance works for
at least four minutes, al-
though the outlet on the
delivery side (e.g. tap) is
closed.
Overheating protection
switches off the appli-
ance.
Remedy
Switch off the pump and pull the power
plug.
Remove the pre-filter and the check valve
and clean it under running water, flush dirt
residues from the bottom of the filler neck
through the filler hole if necessary.
Restart by switching the pump back on.
Check connections on the suction side for
leakage.
Restart by switching the pump back on.
Check if there is sufficient water in the suc-
tion container (e.g. cistern).
Check if there is sufficient water in the suc-
tion container (e.g. cistern).
Check and correct the pressure line for
leakages (dripping water tap).
Restart by switching the pump back on.
There is no sufficient elastic volume avail-
able on the delivery side.
Use a garden hose with a minimum length
of 5 m at a diameter of 3/4" or 15 m at a di-
ameter of 1/2" for garden applications.
Install a pressure compensating hose on
the delivery side between the pump and
the piping with permanent installation.
Restart by switching the pump back on.
Pull out the mains plug.
Depressurise the appliance by opening the
water outlet connected on the delivery
side.
Restart by switching the pump back on.
