I have a Karcher cwp8000 and a error code 56, I cant get rid of the error, When I call for tech support they tell me they have never heard of that error code. Can anybody help me?

Thanks

When you have the error code showing press F1 and it will give you a description. What does that say?

I'll bet he's either fixed it or given up in the last two years.
