Problem
Pump runs, but the suction
action doesn’t take place.
Pump motor runs, but
delivery capacity or
pressure suddenly decreases.
Pump motor doesn’t start
or suddenly stops.
If you have any other problem with your Garden Pump, please contact our Customer Service.
Probable cause
The pump was not filled with
the liquid to be pumped.
The liquid escapes over the
hose which is connected to the
delivery side during the suction
action.
Leaky or damaged suction hose.
Absolutely vacuum-resistant connection is achieved by using
GARDENA Suction Hoses (see point 8. Accessories).
Leaky screw fitting
at the filler
cap
.
Air cannot escape, since delivery
side is closed or remaining water
is in the pressure hose.
The waiting time wasn’t
observed.
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. Accessories) and fill in the liquid to be pumped over the filler
cap
before operation.
Suction filter at the suction
hose is sucked free.
Suction filter or backflow
preventer clogged.
Leaks at suction side.
Impeller blocked.
No power.
Thermal overload switch has
cut out the pump due to
overheating/overloading.
Electric failure.
Remedy
➔
Fill the pump
(see “
4. Operation
").
1. Fill the pump again
(see “
4. Operation
").
2. When starting operation hold
the pressure hose approx.
1 m vertically above the
pump, until the suction action
has taken place.
➔
Seal the connections or check
suction hose for damages.
➔
Tighten the screw fitting
(do not use pliers).
➔
Open all possible shut-off
devices (e.g. spray nozzle) in
the pressure line, or drain the
pressure hose or disconnect
it during the suction action.
➔
Switch on the pump and wait
max. 7 min.
➔
Clean the filter or the back
flow preventer.
➔
Reduce suction height.
➔
Reduce flow rate on the deli-
very side with a control valve,
e.g. GARDENA
art. no. (2)977
.
➔
Clean filter or back-flow pre-
venter.
➔
Eliminate leak.
➔
Loosen the impeller or clean
the impeller chamber.
➔
