When Valve Replacement Is Needed
Signs indicating failure of one or more valves:
- constant water leakage from the bottom after brewing
- pressure in the group does not hold — coffee pours too fast, almost no crema
- excessive pressure — jet-like flow, very firm puck, bitterness
- insufficient pressure — watery coffee, poor crema
- steam output is very weak or absent
- continuous water dumping into the drip tray even when idle
- characteristic hissing or “pssh” sound from the drip tray
- adjusting the crema valve has no effect on pressure
- cleaning and flushing do not resolve the issue
- errors related to pressure or leakage
- visible rust, limescale buildup, or deformation inside the valve
Valve failures are most often caused by hard water, infrequent descaling, spring fatigue, or accumulation of coffee fines and scale inside the valve.
