So I have this Karcher pressure washer that's not working.
Model is K2.97.
It was in use and perfectly fine, then suddenly the motor turned off and now it won't start again
I checked the fuse in the plug, and it works fine.
I removed the outer plastic casing.
I checked the capacitor by eye. It looks ok and smells ok.
I can't hear the motor humming. I've attempted to jump start the motor by turning the fan blade with a screw driver.
For these reasons I don't think the problem is capacitor related.
Maybe a false lead, but I read online that there is some type of safety pressure switch that won't allow the motor to start unless there is pressure to the water inlet on the pump. But looking at the parts list or on the unit itself I cannot find such a switch.
Any ideas?

Also, in the water inlet elbow for the pump there is this little switch. (Bottom right)
I have no idea what it is for.
Could it be the cause of the problem?

take that shit back to K-Mart and buy a decent brand

could be something as stupid as a pinched/severed power wire

there is a small 'piston' that pushes against a switch, this is how it turns off when you aren't spraying as the pressure builds and pushes the switch. check the plunger isn't stuck, they are plastic and break easily ESPECIALLY if you don't put clean water through it.
seen a few where the cleaner that they fucking sell you solidifies in the plunger and jams it shut.

Humming but won't spin sounds like a centrifugal start switch to me.
DISASSEMBLE.
