Possible Causes
Faulty start button or touch sensor, Lid not detected as closed, Water tank not detected, Control board input failure
How to Fix / Troubleshooting
Safety first: Unplug before opening the control panel.
Steps:
- Check basic conditions: Ensure the water tank is full and correctly seated, the drip tray and capsule drawer are in place, and the lid is fully closed.
- Observe indicators: Many Tefal models show icons if the tank or lid is not detected. Resolve any indicated issues first.
- Clean control panel: Wipe the touch panel with a slightly damp cloth and then dry. Avoid excessive moisture that can confuse capacitive sensors.
- Test other buttons: If only the start button is unresponsive, the button or its circuit may be faulty.
- Access and inspect UI board (advanced): Remove the front panel, check the start button switch or touch sensor connections, and reseat the ribbon cable to the main board.
