Suction filter or backflow
preventer in the suction hose
clogged.
Too high suction height.
In case of any other difficulties concerning the suction action,
use GARDENA Suction Hoses with Backflow Preventer
(see point "8. Available accessories") and fill in the liquid to
be pumped over the filler cap
Suction filter at the suction
hose is sucked free.
Suction filter or backflow
preventer clogged.
Leaks at suction side.
Impeller blocked.
No power.
Circuit breaker has switched off
the motor due to overheating /
overload.
Electric failure.
In the case of strong flows (e.g. open hose end, without
connect ing device), noise may result in the hydraulic part of
the pump. This is harmless and does not lead to damage
of the pump. The noise can be removed by lightly changing
the flow (e.g. light opening/closing of a connecting device).
Remedy
v Switch on the pump and
wait up to 5 min.
v Clean the filter or the back
flow preventer.
v Reduce suction height.
