pressure washer

[hopalong]

i,m about to throw in the towel on my karcher 620m pressure washer,after little use it has given up the ghost,it,s just out of warranty,and i cant get it to work.the unit turns on,but it gives only hose pressure.i,ve pretty much stripped it down and put it back together,has anyone had a similar problem,and have they been able to fix it?

Hi hopalong, I had the exact same problem with my 620M. I had it serviced and they fixed it by re-greasing jammed by-pass valve. Hope this helps you.
