11. Troubleshooting

With this garden pump, you purchased a product built to the state of the art and operationally safe. Ne-
vertheless, problems or errors may occur. Therefore, observe the following information about troubles-
hooting.
Garden pump does not take in water
• Open any present shut-off valve on the pressure-side, since air cannot escape from the hose or in the
pump.
• If required, fill water into the suction hose and the garden pump.
• Briefly pull the mains plug from the socket and plug it back in.
• Use a backflow stop at the end of the suction hose.
• The water level is too low or air is sucked in as well.
The garden pump does not start up or stops in operation
• Is the garden pump on?
• Check the power supply or the circuit protection and the FI protection switch. If the FI protection switch
has triggered, disconnect the garden pump from the mains voltage and check for damage (e.g. mains
cable/housing).
• The pump wheel inside the garden pump is blocked by dirt. Disconnect the garden pump from the mains,
remove the hoses and the water filter and flush the inside of the garden pump and the water filter with
clean water.
• The overtemperature protection triggered. Disconnect the garden pump from the mains voltage and let
the garden pump cool off (at least 30 minutes). Remove the cause for triggering (e.g. water temperature
too high, running dry too long, etc.).
Conveyed volume reduces or is too low
• Check the suction hose or its coarse filter for contamination.
• Clean the water filter of the garden pump.
• The garden pump sucks in air since the suction hose is not in the water.
• Check the attachment of the suction hose to the garden pump.
• Check the suction hose for leaks or bends.
• The displacement reduces due to the principle the larger the overhead and conveyor height.
• The hose diameter of the suction hose is too low.
