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 troubleshooting.
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 trig-
gered, 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 aqua sensor is not positioned 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.
The aqua sensor will not trip or switch off.
• The aqua sensor is not positioned correctly.
• Insert the aqua sensor in one of the possible positions (4). Depending on the position, the aqua sensor switches
off the clear water pump when a low water level is reached. Make sure that the aqua sensor is always inserted in
a way that the cable points upwards.
• If the aqua sensor is inserted as shown in the figure in chapter 6, the aqua sensor is deactivated.
