Cause
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 ap-
pliance starts again immedi-
ately and thus switches on and
off frequently.
The appliance works for at
least four minutes, although
the outlet on the delivery side
(e.g. tap) is closed.
Overheating protection switch-
es off the appliance.
Suction pipe blocked
Pre-filter is dirty
Suction side is leaky
The quantity transported by the
pump depends on the transport
height and the connected pe-
riphery
Cross section on the delivery
side constricted, e.g. due to
valve/ball valve that is not com-
pletely opened.
Hose on the delivery side is
kinked.

Remedy
Check and correct the pressure line for leakages (drip-
ping water tap).
Restart by switching the pump back on.
Check system for leakage. If the leakage cannot be
eliminated, install pressure equalization container.
(see special accessories)
There is no sufficient elastic volume available 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 diameter of 1/2" for gar-
den applications.
With permanent installations, install a pressure equal-
ization hose or pressure equalization container on the
delivery side between the pump and the piping.
(see special accessories)
Restart by switching the pump back on.

Depressurise the appliance by opening the water out-
let connected on the delivery side.
Restart by switching the pump back on.

intake area.
Remove the pre-filter and the check valve and clean it
under running water, flush dirt residues from the bot-
tom of the filler neck through the filler hole if necessary.
Check the entire suction side for leaks
Keep max. flow height, see technical data. If neces-
sary, select a different hose diameter or hose length.
Completely open the valve/ball valve.
Remove kinks from the hose.
