My Electrolux Pure A9 air purifier has been running daily for a couple of years and the fan has become noticeably whinier and grindier.
I’ve been looking for a service manual without luck, obviously Electrolux does not provide them.
Any advice how to lubricate the fan would be much appreciated!
Ah, I think you misunderstood the intention of that quote.
Because the manual says that, the fan is likely easily accessible once you remove the filters. From there, with it unplugged (!!!), flip it and maybe you can easily apply that grease.
Ooh, I see! That’s a clever deduction. Thanks!
