The clear water pump does not start or stops during the operation
• Check the mains supply or the circuit breaker and the ground fault circuit interrupter. If the ground fault circuit
interrupter has tripped, disconnect the clear water pump from the mains voltage and check for any damage (such
as mains cable).
• The pump impeller 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 is not positioned correctly.
• The overtemperature protection has tripped. Disconnect the clear water pump from the mains voltage and let the
clear water pump cool down (at least 30 minutes). Eliminate the cause of the trip (e.g. water temperature too high,
dry running too long etc.).
Flow rate is lower or too low
• Check the suction holes for dirt.
• The clear water pump sucks in air because the suction holes are no longer completely under water.
• Check the attachment of the hose to the clear water pump.
• Check the hose for leaks or kinks.
• The more the flow rate decreases the larger the delivery height is.
• The hose diameter is too small, the hose is clogged by dirt.
The float switch is not released or does not switch off
• The float switch is not positioned correctly.
• Attach the cable to the float switch on the side of the cable clamp so that the float switch will properly shut off, for
example, when a low water level is reached in a cistern.
