Do you have a video on how to replace the high pressure hose on this machine as I'm having difficulty in detaching the hose from the connection located through the hose reel? The hose is split so I need to replace it.
You have not fixed this. The problem is that the Spill Valve or Unloader Valve has siezed, perhaps you are in a hard water area. You got close to the problem but you bodged it by unscrewing the Black Pin to force the switch into a closed position. The Pin should be returned to be screwed tight into the top of the Spill Valve. At that point of the video you need to remove the Spill Valve, clean any debris/scale from the barrel it sits in (the same barrel you blew the water from) and also de-scale the Spill Valve and check it is working/moving correctly. To get my Spill Valve out I filled the barrel with WD40 (thin oil) and left it overnight. In the morning I removed the Black Pin (so as not to damage it) and replaced with an 7mm bolt, then carefully rotated the valve until it would pull from the barrel. Replace the black pin and clean as described above or replace. In the UK you can use eSpares e.g. www.espares.co.uk/product/es537916/pressure-washer-spill-valve. (for my Karcher 520M) Now reassemble. The way you fixed it causes the violent start and stop of the washer rather than a progressive start, I don't think it will last long. You may also be at risk having forced the power switch to be on having removed the action of the spill valve. I have no connection with eSpares or Karcher, I just like understanding how to fix stuff.
