The filter on one of my slim phatties suddenly need 30 minutes of warm-up to work properly.. It won’t open fully and bounces back and forth before it stabilizes after 20-30 minutes. In “precision mode” I can also see that it won’t go all the way down to zero but stops at 40.
The filter didn’t behave like this 2 months ago.. (6 months old)
Is this normal behavior?
Edit:
No, this is not normal.
