Jura J8 cleaning sensor?
I’m wondering how the sensor that advises that it’s time to clean the coffee system works. I’m guessing that it’s optical, or does it just count, does anyone know?
Also I’ve just found out that my water hardness has risen from 8 to 250 on a 1-1000 scale.
So I’ll need to decalcify even though I’ve been using filers as I’d based those on 8 instead of 250. Will the machine tell me to decalcify or is this up to me?
