So I spent 3 months chasing a coffee grind that didn't exist
I was getting bitter shots no matter what I did with my Gaggia Classic. Dialed in finer, coarser, changed dose, temp surfed, the whole routine. After 8 weeks of frustration I finally realized my burr grinder needed to be cleaned. There was caked on oil locking the adjustment ring so it wasn't actually moving when I turned it. Anyone else waste months on a problem that was just maintenance?

Buddy of mine spent a whole summer rebuilding a vintage espresso machine. New pump, new boiler, new group gasket, the works. Couldn't get it past 6 bars of pressure. Replaced the OPV valve twice. Tore the whole thing apart three times. Finally took it to a shop and the tech found a tiny piece of packing foam stuck in the pump inlet from when he shipped it. Took 30 seconds to fix.
