11. Troubleshooting
With this deep-well pump, you purchased a product built to the state of the art and operationally safe.
Nevertheless, problems or errors may occur. Therefore, observe the following information about troub-
leshooting.
Deep-well 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. Move the pump back and forth a little. If required, fill water into the deep-well pump or the hose.
If necessary, briefly turn the deep-well pump off and on again.
• Clean intake openings (disconnect deep-well pump from the mains voltage first!).
• The water level is too low or air is sucked in as well.
The deep-well pump does not start up or stops in operation
• Check the power supply or the circuit protection and the FI protection switch. If the FI protection switch
has triggered, disconnect the deep-well pump from the mains voltage and check for damage (e.g. mains
cable).
• The pump wheel inside the deep-well pump is blocked by dirt. Disconnect the deep-well pump from the
mains voltage, remove the hose and flush the inside of the deep-well pump with water.
• The overload protection triggered. Remove the cause of the overload and then push the button (6).
Switch off the deep-well pump if required, and switch if on again after waiting for a few seconds.
• The overtemperature protection triggered. Switch off the deep-well pump and wait until the pump has
cooled off sufficiently (at least 15 minutes).
Conveyed volume reduces or is too low
• Check the intake openings for contamination.
• The deep-well pump sucks in air because the intake openings are no longer completely submersed.
• Check the attachment of the hose to the deep-well pump.
• Check the hose for leaks or bends.
• The displacement reduces due to the principle the larger the conveyor height.
• The hose diameter is too low.
