What to do if my Kärcher Water Pump suddenly stops?
- RRobert KaufmanJul 28, 2025
If your Kärcher Water Pump stops running or suddenly comes to a standstill, there might be several reasons. First, check the fuses and electrical connections to ensure the power supply isn't interrupted. The thermal protection switch may have turned off the pump due to overheating; in this case, pull out the mains plug, let the pump cool down, clean the suction area, and prevent dry running. Also, dirt particles might be jammed in the suction area, so unplug the pump and clean it. The level sensor could also be the cause; check its position and correct if necessary, noting that the pump stops 15 seconds after the level sensor loses water contact. If the level sensor is dirty, clean it.
