Problem
Possible Cause
Remedy
The pump sucks nothing up.
Rotary switch is not turned to
RUN.
v
Restart the pump
(see 4. Operation).
The pump is sucking air
through a leak at a connection
on the suction side.
v
Check all connections and
make them air-tight as
necessary.
Pump is not adequately primed
with the liquid to be pumped.
v
Fill the pump and ensure that
the water is able to flow
back into the pressure line
(see 4. Operation).
Air cannot escape on the pres-
sure side, because the pressure
side outlets are closed.
v
Open the pressure side
outlets.
End of the suction hose is not
in the water, the non-return valve
at the end of the suction hose
is missing or leaking, the suction
hose is kinked, connections are
leaking or the suction filter is
blocked.
v
Check the complete suction
hose from suction point
through to the pump for leak-
tightness and repair any leaks
as necessary. Check the intake
side water supply. If applicable,
clean the suction filter.
