Hi all,

I've got an old Nilfisk Alto Active 2050 which stopped working. Google search indicates the pressure switch actuator is likely the culprit.

So, I've opened it up and sure enough the springs in the pressure switch actuator have rusted and broken apart. That's what happens when the springs are made out of mild steel in a wet chamber!!

The question is - is it worth repairing and can I get the replacement kit in NZ?

I found a repair kit on an Australian online retailer (vacuumdoctor) for AU$145, but at that price it's not economic to repair.

Thanks.

Probably best to take the hint when the web page says obsolete model. The whole kit is what you would need as obviously the seals are leaking to allow water into that mechanism anyway. Kerrick are owned by Nilfisk in NZ but parts, if still available would likely come from Accent Tools.

Update on my findings. Yes, I was aware of the obsolescence of my old machine - I was really just hoping there might have been a fix rather than throw what was otherwise a good machine away. I got redirected to Accent Tools, who indicated no parts available in NZ. So now I've got a fancy new water blaster and selling the old accessories for my Nilfisk.

On the Nilfisk did you get a good stream of water out the nozzle just by pulling the handpiece trigger? On mine the motor switching seemed to be flow determined and any blockage of the nozzle would stop the motor coming on.
