Possible Cause
Rotary switch is not turned to
RUN.
The pump is sucking air
through a leak at a connection
on the suction side.
Pump is not adequately primed
with the liquid to be pumped.
Air cannot escape on the pres-
sure side, because the pressure
side outlets are closed.
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.
