The Karcher at work just died on me recently. If you've seen my bike you'll know I'm not one for washing stuff often, so I don't know a great deal about them tbh. Was running then died like a fuse had gone. Plug fuse still ok. Took the outer cover off it and the motor shaft still spins freely. It did leave little oily spots around as I used it before dunno if that's normal. Is it worth me taking it apart further??
