No water from group head — pump runs but nothing comes out

Water flows continuously from group head — will not stop

Slow water flow from group head — shot takes 40+ seconds

Pump runs but no water — air lock in pump or supply line

Low brew pressure — under 7 bar at group head

Pressure too high — over 11 bar, over-extracted bitter shots

Pressure drops immediately when pump stops — will not hold

Machine not heating at all — stays cold after 15+ minutes

Machine heats continuously — will not cut off, safety valve activating

Intermittent heating — works then loses temperature

Machine trips RCD or circuit breaker when powered on

Water dripping from group head when machine is idle

Leaking around portafilter during extraction

Steam wand dripping or leaking when not in use

Water or steam releasing from safety valve

Internal water leak — pooling under the machine

Boiler constantly overfilling — water from safety valve or wet steam

Boiler will not fill — autofill not working, low water alarm

Pump extremely loud or making grinding noise during brewing

Pump hums but does not turn — no water movement

Loud noise ONLY during boiler autofill — quiet during shot extraction

Hissing from anti-vacuum valve during heating

Clicking or chattering from solenoid area during brewing

Espresso tastes bitter and over-extracted

Espresso tastes sour, weak or under-extracted

No crema or very thin, pale crema

Channelling — uneven extraction, pale streaks in puck after shot

Water dripping from E61 shower screen when idle (lever down, not after shot)

Portafilter jams or is difficult to remove after shot on E61

High-limit thermostat keeps tripping — red reset button needs repeated pressing

Water quality or TDS issues causing probe and scale problems across the machine

Shower screen blocked or warped — needs replacement

OPV spring fatigue — pressure will not adjust to correct range

Safety valve dripping or hissing after pressure normalises

Vibration pump fails to reach target pressure — pump confirmed worn out

Rotary pump making bearing noise — increasingly loud grinding from motor end

E61 group rebuild overdue — multiple valve symptoms appearing simultaneously

Water siphoning back through group head after machine is switched off

Portafilter will not lock or unlock properly — wrong locking position
