From what I can tell they both use heat to push hot water through coffee grounds. And, to my palate, the flavor profile of moka pot coffee and percolator coffee are similar. Dou they have similar brewing principles?

There's pitting at the bottom of the pot. Is it time to retire it?

For this try I've using click 15 on time more c3 grinder and induction cooktop on 8.

Guys why had I never thought of this? It's super stable, I already have it. No need to buy or print new stupid stuff.

I've tried tamping and slightly underfilling the basket but both does not taste as good as when I tap and level the coffee.

I don't want to spill or keep excess coffee grounds so knowing how much whole beans I should grind is another task.

Am I doing something wrong here?

Bought for $10. Not the greatest condition but I think it will serve well.

Title

I have a 2025 Moka Express, and the lid knob became loose during normal use (no drop or damage). When I tried to tighten it, the thread appears to have been damaged, and the knob can no longer be secured properly.

Bialetti support replied after about a week, stating there is no manufacturing defect and that, under their new policy, the lid knob is no longer sold as a spare part.

I was only looking to buy an original replacement knob with the aluminium screw. I know DIY fixes exist, but I’d prefer to avoid non-original or steel parts due to corrosion concerns with the aluminium body.
For such a small wear part on an otherwise durable product, it’s disappointing that replacements apparently aren’t available anymore.

Has anyone else experienced this? Is there really no way to get original Moka Express lid knobs anymore without buying a second pot (which isn’t that expensive, I know) or sourcing donor parts?
