Karcher kb9020

Hi everyone,

I have the pressure washer mentioned above. The device will not start. The normal hum when you which the device on doesn't happen and there's no pressure.

The device was working correctly when I put it away. Just wondered if it was knackered or if there was a valve or something that might need a clean etc.

Changed fuse etc. without success.

Thanks of any help or advice

These machines don't like being put away full of water, but.....
The switching mechanism is called the 'electric box' (quaint!) and that contains the main switch and the motor run capacitor.
I'm not saying buy a new one but if you are handy with a multimeter etc you could do the odd test.
I'd also check that the motor hasn't locked up, by spinning the fan with a screwdriver.
I'm pretty sure the electric box part number is 1.423-114.0.
