Because the switch is broken and stuck in the "on" position. Until you fix it all you can do is plug it in and out for operation. If you are handy you can take the switch out, make the repair of the broken part, and reuse. They wanted 35 dollars for the switch on my Karcher power washer. Yeah, right!

A clogged carburetor is most commonly caused by leaving fuel in the pressure washer for a long period of time. ... This sticky fuel can clog up the carburetor and cause the engine to run stall. If the carburetor is clogged, try cleaning it with carburetor cleaner. https://www.repairclinic.com/RepairHelp/How-To-Fix-A-Pressure-Washer/149---/Pressure-Washer-Starts-Then-Stalls

A modern hot water pressure washer can have complex circuitry and it is a good idea to read the user instructions and have a diagram for reference when troubleshooting - certainly some dismantling will be necessary to trace the power rather further inside than the power cord. If the unit hasn't been used for a time the pump could have frozen and have overloaded the motor when switched on - there is often a facility for the pump to be turned by hand to unfreeze the pump before switching on.

Which breaker does it trip? The MCB or the RCD? If the former, the motor is taking too much current and that might be caused by shorted turns, a defective centrifugal switch (if fitted) or a shorted start or start/run capacitor. If the unit has been standing for a while it could be the pump is frozen - some units provide access for a hexagon key so the pump can be turned manually a couple of revolutions before switching on the power. If the RCD has tripped it is because there is an insulation breakdown and current is leaking to ground.

In my experience with karcher, and other brands, you will be money ahead to replace the pump entirely. Pumps usually cost around $125. There are some times rebuild kits available, but they will often cost over half the amount of an entire pump. Add to that the unloader valve, & you will be way past the cost of a new pump.

most likely motor or pump overheated and seized or burnt out remove cover to the unit and test for motor operation
