Problem Possible cause Remedy
Pump runs but does
not create suction
Leaking or damaged suc-
tion line [Fig. A2].
Æ
Check the suction line
for damage and seal it
so that it is airtight.
A totally vacuum-tight connection can be achieved by
using GARDENA suction hoses (see „9. Accesso-
ries/spare parts“ ).
Pump draws in air at
a connection point
[Fig. A2].
Æ
Seal the connections
on the suction side so
that they are airtight.
There is no water in the
cistern, water tank, water
pipe etc.
Æ
Ensure that there is a
water supply on the
suction side.
Pump was not filled with
water [Fig. A4].
Æ
Fill the pump (see
„4.1.1 Starting the
pump“ ).
Water escapes through
the pressure hose during
the priming process.
1. Refill the pump.
2. Hold up the
pressure hose.
3. Restart the pump.
(see „4.1.1 Starting the
pump“ ).
There is a leak in the
fitting on the filler neck
[Fig. A2].
Æ
Check the seal
(replace if necessary)
and tighten the fitting
by hand (do not
use tools).
Air cannot escape
because the delivery
line is sealed or there
is residual water in the
pressure hose.
Æ
Open the shut-off
valves (for example
nozzle) in the delivery
line or empty the pres-
sure hose.
Air cannot escape
because the pressure
hose is wound up
1. Lay the pressure hose
out straight to its full
length.
2. Route the hose up
from the pump outlet.
3. Do not bend the pres-
sure hose at the pump
outlet.
4. Open all consumers to
the maximum setting.
The priming process has
not yet been completed.
Æ
Wait for up to five
minutes until the pump
pumps water.
Suction filter or backflow
preventer in the suction
hose are clogged.
Æ
Clean the suction filter
or backflow preventer.
The end of the suction
hose is not in water
[Fig. A5].
Æ
Immerse the suction
hose end deeper into
the water.
The suction height is too
great [Fig. A5].
Æ
Reduce the suction
height
In the case of other suction problems, use GARDENA
suction hoses with backflow preventer (see „9.
Accessories/spare parts“ ).
Fill the pump with water before starting.
Pump does not start or
stops suddenly during
operation
Thermal overload switch
has shut down the pump
due to overheating.
Æ
Let the pump cool
down, drain the pump
and refill it.
Æ
Note the maximum
media temperature
(35°C).
Pump has no power.
Æ
Check the fuses and
electrical connectors.
RCD switch has tripped
(residual current).
Æ
Remove the plug from
the mains socket and
contact GARDENA
Service.
Pump is running, but
the flow rate decreas -
es suddenly
The integral filter is
clogged
Æ
Clean the integral filter.
The end of the suction
hose is not in water
[Fig. A5].
Æ
Immerse the suction
hose end deeper into
the water.
Suction filter or backflow
preventer in the suction
hose are clogged.
Æ
Clean the suction filter
or backflow preventer.
There is no water in the
cistern, water tank, water
pipe etc.
Æ
Ensure that there is a
water supply on the
suction side.
Suction line is leaking
[Fig. A2].
Æ
Rectify the leak.
