  If your Kärcher Water Pump suddenly stops or doesn't start, the issue might be with the power supply. Check the fuses and electrical connections to ensure they are properly working. Alternatively, the thermal protection switch in the motor may have turned off the pump due to overheating. If this happens, unplug the pump, let it cool down, and make sure the ventilation slots on the casing are clear before restarting. If the problem continues, have the pump repaired. Another cause might be the pump overheat protection switched off the pump due to extended interruption in water supply. Pull the mains plug, let the pump cool off. This can take some time. After that, restart the pump.

  If your Kärcher Water Pump is running but not pumping water, there could be several reasons. First, there might be air in the pump; refer to the manual chapters on "Preparation" and "Operations" for instructions on how to remove it. Second, the suction pipe could be blocked; in this case, pull out the mains plug and clean the suction pipe. Finally, the pre-filter might be dirty; remove it and clean it under flowing water, and rinse any dirt residue in the fill neck via the hose line connections.

  If the amount of water your Kärcher Water Pump is pumping is reduced or too low, start by checking for a blocked suction pipe. Pull out the mains plug before cleaning the suction pipe. Also, the pre-filter may be dirty, so remove it and clean it under flowing water, rinsing any dirt residue in the fill neck via the hose line connections. Another possible cause is a leak on the suction side; inspect the entire suction side for any leaks. Finally, remember that the pump's output depends on the transport height and connected equipment. Check the maximum delivery height in the technical data. If necessary, use a larger or shorter hose.
