Karcher just stopped working
It sounds like a motor capacitor burned up. Alternatively, a wire could have vibrated loose from the capacitor. Look, but do not touch the capacitor(s), as they can hold a charge that can hurt -- or even kill you.
The trick is to be certain they are discharged before handling. To do this, use a screw drive with a well insulated handle and touch the top of the capacitor where the wires are. The metal blade of the screw driver should touch both sides of the capacitor at the same time. Then, if there is any charge being stored, you will see a pop and that's it -- it is not discharged.
You can buy a new capacitor at any place that sells AC and Refrigeration supplies. Take the old one with you so they can match the microfarad capacity. Just venturing a guess here, but if you want one that fits perfectly back into place you may have to order it from Karcher (because those units are built in Europe I think).
2. The motor may have shorted (gone bad). If that has happened, perhaps you have some warranty. Electric motors are generally warranted a little longer than the PW in general. With Karcher, I don't know. If there is no warranty on the motor, it may be better to buy a new pw than to replace the motor.
3. The problem could be a mechanical issue with the pump/unlooader. However, I would think this would be the least likely scenario.
If what I've given so far doesn't get you rolling in the direction of being resolved, please followup here. I'll be watching. And if it does get you moving in the right direction, please take a sec to rate me. Thanks!
