My BOSCH Aquatak 110 plus pressure washer after a few years of service stopped working.
The pump was operating normally but no water exited the high pressure hose.
I started troubleshooting by disconnected the pressure hose and tested it using compressed air, but no air exited the hose when I pressed the handle valve.
AHA! I thought, there is a blockage in the hose! So I started testing it thoroughly.
When I opened the valve in the handle, I discovered that the main plastic part, that operates the valve when you press the handle, was broken in two and instead of allowing the water to pass through it, it blocked the water exit.
The front of it (arrow shape), that blocks-unblocks the water flow according the pressing of the handle, was separated from the body and the high pressure water flow was completely blocked regardless of handle operation.
A spare part is not available! I have to buy the complete handle for the ridiculous price of 100 Euros when a new unit costs 125!!!!
To make a new one was a simple job.
A piece ofbrass bronze and two hours of fun on the mini lathe and the new part stood proud next to the old one wearing its new o-rings!
New o-rings a little lubrication, back to the handle and the pressure washer is as good as new again.
Thanks for reading.
