The bypass valve is most likley jammed. Remove the cover from the machine, then remove the chemical tank. Unscrew the micro switch cover and manually operate the micro switch. If the motor runs the bypass valve is faulty. Replace the valve along with the stem seals on the valve.

HI Your machine wil start and stop if you have any external leaks when the machine is running at not pressing the trigger. Please start the machine and not pull the trigger and look form leaks. A common one is around the high pressure hose outlet and also the trigger.

You did winterize the machine? Leaving water in a powerwasher will freeze and damage the pump. It's a common happening, because people don't think of it or are not told by the maker.

Karcher k 2.36 smoking and flashes of light inside the machine.


Hi:
This sounds like a short circuit or motor problem. They are relatively easy to take apart. If you see a burned wire or connector this can be repaired. If not, it is the motor and probably too expensive to repair considering the price of a new one.

Power washer just died


hi. you will need to go inside the machine to have a look, but it might just be a micro switch on the bypass valve stuck.
you can not miss it, there is a wire going to it, just unclip and check with a meter when pressing the little switch in and out.

Karcher pressure washer won't start


Dear ralph_birtwi,
Most pressure washers when their gun is released, the machine stops automaticaly. This is done ny means of a control valve. When the gun is closed...pressure is built and the control valve moves and switches a micro switch off. In your case the micro switch is still closed in off position. Now this happens if a machine is left and stored with pressure in it., This control valve could get jammed and leaving the micro switch in off position. It could also stay in off position by sticking, due to incorrect chemical.
So the control valve or even called spill valve, must be renewed.
Sometimes a little lubrication with the right type of silicon grease will get the control valve working again. This job is sometimes delicate and better done by a qualified technician.
Regards,
fulltech.

Motor runs constantly with low pressure.


What you described I would think that it a switch problem, I would go to Karcher.com and order an original part for this and start over with the electrical portion and then go from there.
