RE: Disassembly of F&P Icon
Hmmm...
Sorry I can't help with much of what you are asking, but I did find a couple things that you may find helpful.
This might give you a hint of the proper sequence of disassembly and reassembly of the ICON.

And this might provide you with some sort of free service or replacement. I'm sure you will have to do some digging to find out if it applies to your ICON and if it is a valid course of action in your case. I didn't read all of this recall, but it is kind of dated.

There doesn't seem to be much info on repairing the ICON, so hopefully you enjoy tinkering and don't run into a need for any special tools to dig into the heart and soul of your machine. But a bit of tinkering might save you a bunch of money.
Best of luck.

That was helpful RayBee, it shows that the motor can be disassembled so an odd screwdriver and a few drops of silicone should be all I need.

Outstanding Hanrahan!
After watching the YouTube again and pausing it a few times, it looks like F&P uses a little brushless motor. The silicone oil should easily penetrate even shielded bearings. I use the stuff on numerous tiny bearings in my radio controlled model helicopters. Works great.
Make sure the impeller isn't touching anything it shouldn't too while you are in there performing surgery.
