This happens to my wife's smaller one (maybe 6 cup) every few months. Generally the gasket is the primary issue and the second issue is she doesn't tighten the 2 halves together very well.
Try changing the gasket as another poster suggested.
I did. I forgot to mention that. The actual problem was that the funnel no longer sealed tightly with the water container. Using thread tape repaired the seal. Replacing the funnel would also work, but thread tape is very inexpensive.
Aha. Innovation. I like it.
That’s a useful thing to know, thanks!
Is thread tape going to be safe?
Yeah it’s intended for pvc water pipes - it’s safe.
I meant more so because of the extreme heat it will go through. It may melt or leech chemicals into your coffee.
