How to Fix / Troubleshooting

Safety first: Unplug the machine before cleaning the control panel.

Check safety interlocks: Ensure the water tank, drip tray, dreg drawer, and service door are all fully inserted and closed.
Cancel previous cycle: Turn the machine off and back on. Allow it to complete any automatic rinsing or self-test before pressing brew.
Clean control panel: Wipe the buttons or touch surface with a slightly damp, non-abrasive cloth. Dry thoroughly. Moisture or dirt can prevent proper contact.
Try alternate drinks: If one specific button does not respond but others do, the individual switch may be faulty and require replacement.
If no buttons respond: The user interface board or ribbon cable may be defective. Professional diagnosis is required.
