Nilfisk O Ring Service Kit

My E140 pressure washer doesn't seem to be putting out as much pressure as it used to. It also pulses by itself when I am not using it.

Yesterday also I had forgotten to turn it off and the motor was running by itself for some reason! Is this a switch related issue or could it be something that the washer kit my resolve? If its switch related will it need a new one or does the old one need maintenance on it?

I did receive the washer service kit on the weekend and replaced the green washer that is at the end of the Nilfisk hose which was green originally and this didn't change how the machine behaved.

I've got several washers in the kit however looking at the pictures in the ebay ad its not obvious to me where they all go. Where it has pictures with arrows I've checked the parts and some of the end pieces don't seem to have any old washers in them for me to replace. Is there a guide anywhere on each replaceable washer?

I had the same problem with mine and a guy on here replaced 3 parts, I did exactly what he said and it stopped the pulsing completely. I'll try and find the link

Thanks mate. Did you do it yourself or send it off for someone to replace. I can't find a link to the 3 parts for sale.

I did it myself, was very easy. Just take photos as you go along. The screws are torx. I can't remember what number though.

I'm pretty sure I bought them off nilfisk themself, the spares department.

I've done mine too, same issues as yours.... I cleaned out the strainer that's inside the inlet pipe, replaced the microswitch, pressure valve and the capacitor..... Although that probably won't need changing on yours

I got my parts from spares giant, total cost was around 30 quid, plus I upgraded the hose to rubber, its made a big difference and it's like new again

I've replaced 3 of the washers along the lance and hose connector and the last one that needs doing is as show in the video. Has anyone found an easy way to remove the old washer? Does the white nozzle come out if you remove the sliding pin and try and plier it out?

None of the other washers has made a difference to the pressure and pulsing so it looks like I may have to go switch route as I can't see this last washer making a differece. But before I do I may try my neighbours lance to see if it is a lance issue. That said I'm not sure if the switch will work - if I can acutally work out how to replace it and may then wish I'd just bought a new pressure washer.

Mine was from the refurb outlet about 3 years ago @110 - had my monies worth?

Many of them have 3 year warranties, worth contacting Nilfisk? I had an issue with mine after about a year and they replaced the full pressure washer, they were excellent to deal with.

Mines doing this now as well. I'll open it up first and see what the issue is before buying stuff.
