Why Lowara GTKS20 Extender motor runs but no water is delivered?

  Michelle WalkerAug 2, 2025
  If the Lowara Extender motor runs but no water comes out, there might be several reasons. First, ensure there is water available on the suction side and inside the pump by filling the pump or suction piping and opening any on-off valves. Second, check for air in the suction piping or pump and bleed the pump, inspecting the suction connections. Also, verify that there is no loss of pressure on the suction side, checking the NPSH and modifying the system if needed. Furthermore, inspect the check valve to ensure it is not jammed and clean it if necessary. Clear any clogs in the pipe. Finally, for three-phase motors, confirm the rotation is correct and change the direction of rotation if it's not.

  If the Lowara Extender motor isn't starting, first ensure the power supply is properly connected. If that's not the issue, check for triggering of the motor protector and eliminate any malfunctions. For single-phase motors, the motor thermal protector may have triggered; wait for it to reset automatically. For three-phase motors, check the automatic switch in the electric panel and reset it if necessary. Finally, if none of these steps work, the motor itself may be defective and require repair or replacement.

Why is my Lowara GTKS20 Extender too noisy?
- W
  William WolfAug 25, 2025
  Excessive noise in the Lowara Extender could be due to water return when pumps stop; check the check valve. Cavitation could also be the cause; check the suction. Finally, the pump rotation may be hindered; check for undue mechanical stress on the pump.
