Machine displays ER11 and steam function is disabled

Safety: Unplug the machine and allow the steam boiler to cool completely. Never open the machine while the boiler is under pressure.

• Check for blocked steam wand:
  • Remove the steam tip and soak it in hot water to dissolve milk residue.
  • Use the supplied cleaning tool or a fine pin to clear the steam holes.
• Descale steam circuit:
  • Run a descale cycle focusing on the steam circuit if your model supports it.
  • After descaling, run steam for 30–60 seconds to flush remaining solution.
• Reset attempt: After cooling and cleaning, power the machine back on and test steam. If ER11 persists, the steam thermostat or sensor may be faulty.
• Internal inspection (advanced):
  • Access the steam boiler and locate the steam thermostat/thermal cut-out.
  • Check for signs of overheating or a manually resettable thermostat (some have a small reset button).
• Repair: Replace the steam thermostat / thermal cut-out if it has failed. Investigate and correct any underlying cause of overheating (scale, blocked wand, faulty control).
