If your Kärcher Paint Sprayer pump stops suddenly, there could be several reasons: * A power supply interruption: Check the fuses and electrical connections. * The thermal protection switch may have turned off the pump due to overheating: Pull out the mains plug, let the pump cool down, clean the suction area, and prevent dry running. * Dirt particles jammed in the suction area: Pull out the mains plug and clean the suction area. * Pump operation stopped by sensor: Check the position of the level sensor.
