Thank you for your detailed replies, and for looking at the youtube video.

It is as I feared: cleaning the internal drive had no effect whatsoever. It still spits out the disk which worked fine for months before.

I can only hope it's that Bourns element and not the Sander-Wozniak Integrated Machine (SWIM).

Right now I know more about the Bourne Legacy than soldering on a motherboard, but that is about to change.

Check back in a few weeks when I've acquired the skills and tools and I'll give you an update. Or look for a smoldering hole in the ground in north-eastern Ontario.

If anyone feels so inclined to point to a basic kit list of what I need to change this filter... much obliged. The Torx screwdriver I have

Thanks again!
