So it looks like my Karcher 520M pressure washer has squirted its last, Not sure exactly what the issue is with it , motor running constantly, not shutting off and no pressure from the lance. Tried removing and cleaning the spill valve to no avail, possibly needs seals replacing somewhere but Ive had it for 10+ years so maybe not worth the fixing.
What do you recommend as a replacement, another Karcher? something different?
