Small Engine Problems? Ask an Engine Mechanic for Answers ASAP
I did some digging online and found a website-- www.pressureparts.com, that has access to some Karcher parts, but was not able to find brushes or even a motor for your model, though they did have a parts breakdown for it. You might try calling that company to see if they can get their hands on those parts. The cost of replacing parts on your pressure washer may justify just replacing the whole pressure washer altogether...I believe I saw a new one online while I was looking for parts for just over $100.00, so that is something else to consider. Good luck to you and please let me know if you need anything else.
