    Hello, I have a Top Craft pressure washer. I have a problem, because it works weird, i.e. when taking the water it is ok, but when the lance is not used, the engine turns on and off alternately. If I do not turn it off, then after a long while the engine works non-stop and then I can only disconnect the plug from the socket. What could this be caused by? How to fix it ?
    I will mention that the washer does not leak so it should be ok.

    It is a washer with a karcher pump inside where there is a pressure valve.

    Personally, I do not know this type, I drew conclusions from my washcloth. It would be better if you went out into the daylight, take photos in higher resolution of the elements to which the wires are connected.

    1.Where the other end of the marked wire is connected.
    2. Where is the cable with a plug connected.
    It is true that there are fragments in the photos, but nothing can be deduced from them.

    in my case it is different because everything works except switching off when a given pressure is reached

    It means that you haven't even bothered to look, you're not helping. Wear of an element can manifest itself with various symptoms. Disassembly will not miss you anyway,

    "After pressing the trigger on the lance, the washer did not turn on" so it's not what I was doing
    to ensure that this chemical valve is used as a pressure valve

    a very nice description, only that this valve is nowhere to be found or hidden

    when it comes to the switch, it is an ordinary switch that only cuts off or gives voltage to the motor

    That's why you were supposed to undress and check, because so far we don't know anything.

    That's right, every device should have such a "switch", it is used to manually control the washer. However, there may be a second, mechanically connected
    something that will automatically cut the power when the pressure rises. And the next step will be to disassemble the white housing, photos are welcome (full focus).
