  • Q KB 9030. 1.423-114 1 Answer

    My Karcher runs for about three minutes, then the pressure stops, wait for about a minute and then goes again , does this repeatedly. No water leaks and when it going pressure is perfect.

      If the motor stops even when the water is running and does not start immediately then it is likely the motor has overheated and it will take a while to cool before running again. If this is the case suspect a failing motor.

      Hi Troll, I'll need your washer's seven digit production number to answer this, as different models have their valves placed differently. This number can be found on the silver plate of your washer.
