Whilst awaiting a capacitor for my Verona (still waiting) I started using my faithful old Classic with Mr Shades PID.
Coffee coming out very tasty, then coffee temp started declining 93 - 88 as pour progressed.
Checked parameter settings all OK. Checked PT 100 OK, reseated with fresh compound.
Tried M/ch again temp slow to reach 88, tried steam, very rapid rise to boiling/ kettling sound. switch off. This with RO water. Conclusion PID kaput ?? Any electronic experts have other thoughts ? Moka pot not so tasty😝
