Hi i got the same machine with the same problem.I rang Karcher and you can buy a new capacitor for around $45 , now to buy a new machine,Super cheap spares have one similar for $89 not worth it spending that much on a capacitor and perhaps it wont work..

Has anyone ideas where I can purchase another. As in a previous query the motor tries to start but only moves a little, yet it spins quite freely when turned by hand. The body of this capacitor is obviouly swollen through heat.
