I have a 2 year old Karcher G2600 VH. Intermittent use, mainly cleaning siding and gutters.
While washing gutters yesterday it surged under use, but not all the time. It acted like it had air in the line, but water supply was good, and the problem came and went. I was able to finish my project, but at the very end, the pump started pulsing, for want of a better word, very rapidly, and water started leaking from the general area where the three main components of the pump join together.
I did pull the spill valve, after watching the Youtube video. It appeared clean, with no visible deposits or other problems. I reassembled it, hooked up the water supply, and the pump again leaked, with the engine not running.
What should my next step be? I'd like to repair this myself if possible.
