11. Troubleshooting
With this clear water 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 troubles-
hooting.
Clear water 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 clear water pump or the hose.
Briefly pull the mains plug from the socket and plug it back in.
• Clean intake openings (disconnect clear water pump from the mains voltage first!).
• The water level is too low or air is sucked in as well.
The clear water 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 clear water pump from the mains voltage and check for damage (e.g.
mains cable).
• The pump wheel inside the clear water pump is blocked by dirt. Disconnect the clear water pump from
the mains voltage, remove the hose and flush the inside of the clear water pump with water.
• The float switch has not been placed correctly.
• The overtemperature protection triggered. Disconnect the clear water pump from the mains voltage
and let the clear water 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 intake openings for contamination.
• The clear water pump sucks in air because the intake openings are no longer completely submersed.
• Check the attachment of the hose to the clear water 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.
Float switch does not trigger or does not switch off
• The float switch has not been placed correctly.
• Connect cable to the float switch to the side at the cable holder so that the float switch switches off
correctly when a low water level is reached, e.g. in a cistern.
