How to Fix / Troubleshooting

Safety first: Unplug the machine before deep cleaning.

  • Clean removable parts: Remove the water tank, T DISC holder, drip tray, and cup stand. Wash all with warm soapy water, rinse, and dry thoroughly.
  • Run cleaning cycles: Fill the tank with fresh water and run multiple rinse cycles without a disc.
  • Descale: Perform a descaling cycle if not done recently.
  • Drying: Leave the brew head open and the tank removed overnight to allow internal areas to dry.
  • Prevent recurrence: Empty the tank if the machine will not be used for several days and clean the drip tray regularly.
