You are very welcome. If this video helps to save people who will follow my instructions up to 100 Euro or more (estimated price of the spare parts & labour), I am happy. I believe that anybody is able to service (with the help of this tutorial), their very good and easy to service Nilfisk power washer. Good luck. S.
Hi from Germany. I 6:40 have a Nilfisk 150.2 that breaks the inlet part where the water hose is attached within seconds after activating the pump by pressing the pistol button. There seems to go high pressure in the wrong direction backwords. What would you suspect to be the problem? KR
Hi, I have no personal experience with this so I can only guess. First I would make sure I don't have a blocked nozzle, gun or high pressure hose anywhere. So you have to check if the water passes freely through the system and the nozzle at the end. If the nozzle is blocked, the machine will create pressure when the gun is pressed, but the water pressure cannot release the machine where it should and this can cause similar damage. But that is only one of the reasons. Try starting with this. Then maybe the misplaced O-ring (roughly 11.8mm x 2mm) mentioned in the video that is inside the Start-Stop valve can do it. Please make sure that you put it inside the white front part exactly where there is a place for it (groove). I describe it exactly in the video, where it should be and where you must not place it. People often put it on the back and the machine doesn't work properly and it gets damaged. Hope this helps. Greetings from Slovakia. S. N.
After watching our video tutorial, I would strongly encourage you to read the manual provided by Nilfisk and an authorized Nilfisk dealer Northwestpowerwashers UK for their customers and the general public before you start fixing your machine. There is only one thing I suspect is not mentioned correctly - the amount of oil needed to be filled into the oil chamber when changing the oil. I think you have to pour in more oil - I think 60 ml is not enough but not sure (I have seen a couple of opened oil chambers and they were nearly full with old oil to be replaced - more than 60 ml for sure. For the proper amount of oil please consult with your Nilfisk service center. drive.google.com/file/d/1HGoOA_gbvHEl7bYwpUWZskkTHbGJZWoj/view?usp=share_link
I have problem with start stop valve. I replaced old valve with new and when I turn on water, it leaks through hole on black part of start stop valve where microswitch connects. What is problem?
I can only think of the following things you could have done wrong. Usually, people damage the new rubber O-ring on the new Start-Stop Valve, which then leaks water and pressure by misfitting the new O-ring, which is shown in detail in the video at 3:43 with how to place it there correctly and then of course also before the end of the video when I immediately install it there. If you place it incorrectly (inappropriately), you can damage it, which can result in the water leakage you mentioned. I do not suppose that you would be unlucky enough to receive (or buy) an incomplete or damaged Start-Stop Valve. I would suggest you dismantle the entire Start-Stop valve again, watch the entire video in detail, and proceed accordingly. In that case, it must work for you. If you have already accidentally damaged the rubber O-ring that I mentioned in the video, try to buy a new cheap O-ring of size 12 mm x 2 mm made of Polyurethane (abbreviation PU) or Nitrile (NBR), but it must be of hardness "90 SH ", which are cheap and try it out with them. They are not original O-rings, and they are probably not exactly the same size as the original ones, but I have had one high-pressure cleaner for quite a long time and it works well with this type of O-ring. The original O-rings in the Start-Stop Valve will probably be "FKM" type rubber, but I don't know for 100%, as Nilfisk uses different types of rubber for the O-rings in different types of high-pressure cleaners and in different places. But I assume that they are all 90 SH hardness, as this type of rubber hardness is necessary if the high-pressure cleaner works with a pressure greater than 100 bar. In this case, classic cheap O-rings of the NBR 70 SH type made of Nitrile Butadiene Rubber (NBR) are not sufficient. I hope this helps you at least a little. Greetings from Slovakia :).
