The product must be stored away from children.
1. Unplug the plug of the mains cable from the mains socket.
2. Close any shut-off valves in the suction line.
3. Open any shut-off valves in the pressure line (accessories, water
stop, etc.).
Therefore the pressure line is depressurized.
4. Unscrew the screw fitting
(8)
screw by hand.
Therefore the pump is drained.
5. Tilt the pump in the direction of the drain (approx. 45°) so that the
pump empties completely.
6. Unscrew the suction hose and the pressure hose.
7. Tighten the screw connection
water drain screw (8) by hand (do not use pliers).
8. Clean the pump (see 4. MAINTENANCE).
9. Store the pump in a dry, enclosed and frost-free place.
6. TROUBLESHOOTING
DANGER!

Risk of injury!

Risk of injury due to accidental starting.
v Unplug the plug of the mains cable from the mains socket.
6.1 To loosen the impeller [ Fig. T1 ]:
An impeller blocked by dirt can be loosened.
v Turn the shaft of the impeller
Therefore the blocked impeller is loosened.

6.2 Troubleshooting table:

Problem Possible Cause
Pump is running, Leaky or damaged suction line
but the suction action [Fig. A2].
doesn't take place
Pump sucks in air at a con­
nection point [Fig. A2].
No water available in
the cistern, water tank,
water pipe, etc.
Pump was not filled with water
[Fig. A4].
Water escapes during the
suction process via the
pressure hose.
Absolutely vacuum­resistant connection is achieved by
using GARDENA Suction Hoses (see 8. ACCESSORIES /
SPARE PARTS).
Screw fitting on the filler neck
is leaking [ Fig. A2 ].
Air cannot escape, since the
delivery line is closed or
remaining water is in the
pressure hose.
Air cannot escape because the
pressure hose is coiled.
Suction time of 5 min. was
not waited for.
Suction filter or backflow
preventer in the suction hose
are clogged.

(5) of the filler neck (6) and the water drain
(5) on the filling opening (6) and the
(9) clockwise with an insulated screw driver.
Remedy
v Check the suction line
for damage and seal so
is airtight.
v Seal the suction side con­
nections airtight.
v Make sure that the water
supply is on the suction side.
v Fill the pump
(see 3.1.1 To start the
pump).
1. Fill the pump again.
2. Hold up the pressure hose.
3. Start the pump again
(see 3.1.1 To start the
pump).
v Check the seal (replace
if necessary) and tighten
the screw fitting by hand
(do not use pliers).
v Open any shut­off valves
(e. g. nozzle) in the delivery
line, or drain the pressure
hose.
1. Lay out the pressure hose
straight along its entire
length.
2. Lay the hose from the pump
outlet upwards.
3. Do not kink the pressure
hose at the pump outlet.
4. Open all consumers maxi­
mum.
v Wait up to 5 minutes for the
pump to pump water.
v Clean the suction filter or
the back flow preventer.
Problem Possible Cause
Pump is running,
The end of the suction hose is
but the suction action
not in the water [Fig. A5].
doesn't take place
Suction height is too high
[Fig. A5].
In case of any other difficulties concerning the suction action,
use GARDENA Suction Hoses with Backflow Preventer
(see 8. ACCESSORIES / SPARE PARTS). Fill the pump with
water before starting it.
Pump does not start, Thermal switch has turned
or stops suddenly during the pump off because of over­
operation heating.
No power supply to the pump.
RCD has triggered
(residual current).
Pump is not switched on.
Pump is running,
The end of the suction hose is
but the delivery
not in the water [Fig. A5].
drops suddenly
Suction filter or backflow
preventer in the suction hose
are clogged.
No water available in the
cistern, water tank, water
pipe, etc.
Suction line is leaking [Fig. A2]. v Eliminate the leak.
Impeller is blocked.
Pressure hose is kinked.
NOTE:
Repairs must only be done by the GARDENA service departments or
specialist dealers approved by GARDENA.
v For any other malfunctions please contact the GARDENA service
department.
