No coffee, or the pump buzzes
No coffee comes out, or the pump just buzzes
The manual's causes first:
- Tank empty, or not pushed in so its valves are shut.
- Filter blocked, or the perforated insert missing. Clean it.
- Spout holes blocked. Clean them.
- Limescale. Descale.
Still nothing: owners find scale in the thin PTFE lines (Tom's Coffee Corner), a failed anti-drip valve (Igor Kadulenkov) or a worn pump (Coffee Grump).
