11. Troubleshooting

With this submersion pressure pump, you purchased a product built to the state of the art and operatio-
nally safe. Nevertheless, problems or errors may occur. Therefore, observe the following information about
troubleshooting.
Submersion pressure 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 submersion pressure pump or
the hose. Briefly pull the mains plug from the socket and plug it back in.
• Clean intake openings (disconnect submersion pressure pump from the mains voltage first!).
• The water level is too low or air is sucked in as well.
The submersion pressure 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 submersion pressure pump from the mains voltage and check for damage
(e.g. mains cable).
• The pump wheel inside the submersion pressure pump is blocked by dirt. Disconnect the submersion
pressure pump from the mains voltage, remove the hose and flush the inside of the submersion pressure
pump with water.
• The float switch has not been placed correctly.
• The overtemperature protection triggered. Disconnect the submersion pressure pump from the mains
voltage and let the submersion pressure pump cool off (at least 30 minutes). Remove the cause for trig-
gering (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 submersion pressure pump sucks in air because the intake openings are no longer completely sub-
mersed.
• Check the attachment of the hose to the submersion pressure 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 clamp holder so that the float switch switches off
correctly when a low water level is reached, e.g. in a cistern.
