Pressure Washer Buggered...?

Hi,

I have a Nilfisk pressure washer. Washing the daily a few weeks back when the pressure suddenly dropped as the wife started using the shower. Not sure why, doesn't usually do this. Anyway, it started to struggle and smell so I immediately switched it off; as I was nearly done anyway, I put the washer away and finished off my rinse using the garden hose.

This afternoon I gave it a go again and it immediately made a funny noise, accompanied by a burning smell. Guessing the motors done for! Anyone know if this can be fixed? Or am I forking out for a new one...?
 
I would have thought by the time you’ve ordered hopefully the correct part and fitted it you would probably be as well buying a new one, having said that I’ve a karcher pressure washer for probably 20 years and it has been stripped down and repaired several times, nothing major though, and has bits of trim etc missing and held together with duck tape, I keep promising myself a new one but while ever it’s working I’ll stick with it.
 
My neighbour was throwing out a karcher they ran it without water on and it was dead, I checked the fuse still dead, then disconnected the lance and attached the hosepipe and left it with water running through it for 15 minutes, back to normal. Karchers have a thermal cut out, wonder how many have been thrown out
 
Hi,
It's not dead, the output is maybe 40%, plus it makes a gurgling/rattling noise, accompanied by the burning smell.
 
I have a Qualcast one, that started losing pressure so I stripped it down and cleaned and reseated the rubber seals on the 3 pistons and its been ok since.. just be aware that where the swash plate that acts on the piston ends is full of oil so make sure its on its end before removing the bolts

Most marriages can be fixed with a bit of effort on both sides. My wife left my old Karcher out in the snow and killed it. It was tough but we worked though it.

New wives are expensive so it might be cheaper to just spend that money on a new pressure washer.
 
Not having much joy with this!
Got some new carbon brushes as they were only a tenner. Gave it a good clean and put the new ones in and seemed to work ok for a short while; then it started smoking!
:headbang:
 
Just bought a Kranzle automatic unit with 10 year warranty to replace / supplement my 30 year old Karcher which is leaking quite a bit. I will take a look at the Karcher, but the idea of an automatic pressure washer that switches on when you use the trigger was very tempting rather than having to switch it on and off all the time ...

I paid about £200 for the karcher 30 years ago, so has done well. The Kranzle is now £600, but does look to be a great unit.
 
I have a go at fixing most things but was beaten by my old Karcher, the internals had no adjustment and no service replaceable parts. I'd had a decade's use out of it so the bits went in the bin. RIP Karcher.
