Problem
Pump runs, but the suction
action doesn't take place
The GARDENA Garden Pump is essentially maintenance-free.
The pump must be flushed through after discharging chlorinated
swimming pool water.
1. Pump through lukewarm water (max. 35 °C), possibly adding
a mild cleaning agent (e.g. detergent) until the pumped water
runs clear.
2. Remove residuals according to the waste disposal laws
applicable in your area.
DANGER! Electric shock!
Risk of injury due to electric shock.
v Disconnect Garden Pump from the mains before
trouble-shooting.
An impeller blocked by dirt can be freed again.
v Turn the impeller bolt
This will free the blocked impeller.
Possible Cause
Pump sucks in air at a joint.
Leaky or damaged suction
hose.
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.
Absolutely vacuum-resistant connection is achieved by using
GARDENA Suction Hoses (see point "8. Available accessories").
