Have you got a pulsating Nilfisk power washer Nilfisk E 140.3 (or 130.3, 145.3)? Please watch Part 5. (Non-Return Valve Replacement) as we show you in our Nilfisk E 140.3 DIY Tutorial, we know how to repair it by replacing one of the most common reasons (no it is not a Start-Stop Valve as most people think) for pulsation. Pulsation can be occasionally caused by some other issues like water leaks from the high-pressure gun or pump (worn out O-rings or water seals or inlet/outlet valves) etc.
Please look down at the description to see the chapters of the video.
If you decide to watch the tutorial and learn how to fix this kind of pressure washer, you will be able to fix pumps on the following Nilfisk hobby class power washers (there is the same Nilfisk Thrust Collar Water Kit; for all of them (Product number: 127 440 081).
