Very interesting. I currently lubed my seals with Super Lube which contains PTFE. I'm now curious when/where I will see this buildup? Are the greaseless seals simply Viton? Whatever seal material KvdW supplies for my machine, they only last 6month to maybe a year (even with no use). I would switch to these Viton seals

As the seals are used they enlarge. The diameter (nominally about 50mm) increases by 2-3mm. At some point it becomes harder to lock in and leakage occurs.

If silicone based grease is applied. I would say it should based on what I have read. How much? Donno. Is swelling causing you any problems? For me, I did not notice swelling. But the seals do seem to have softened up and stick far more to the mirror smooth surface of my group

Are any Canadians in this thread that have gotten anything in Canada with a Blueberry chocolate profile?

To be fair, I did like the Bad Boy Espresso blend I had from Brulerie. The other offerings were just ... not good to me. That monsooned robusta blend was literally impossible to pull properly on 2 different machines. So, that has me scratching my head. The strangest thing that I've ever experienced with a coffee
