Worried,I started looking into pump pressure,maybe I should reduce it a bit?
Perhaps it was a water temperature problem,should I consider PID'ing the Zaffiro?
Both solutions concerned me a little as it meant opening up the machine and 'tinkering'.
The answer came to me in bed at 5am this morning
After 8o'clock in the evening I only drink decaf,I know, but if you saw me you'd realise I need my beauty sleep.
Now I find my decaf needs a slightly finer grind than other beans,so I drop the Rocky half a step or more before filling the pf.
Following evening,having forgotten to reset Rocky during the day, I again drop a step........you can see where this is going can't you........day after day all week I've been grinding finer and finer and finer.
I realised shot times were fluctuating a bit but I hadn't made the connection.(Feel free to call me stupid)
This morning I reset the grinder back to it's usual position,around 10.I discovered that over the week I'd increased the fineness of the grind by about 5 steps in all !
I think it's time for a little bit of sticky tape in the appropriate place on the grinder dial.
Senility is on it's way
