This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Defective Start button on touch panel, Basket not fully inserted triggering safety lockout, Faulty basket interlock switch, Control board input failure

How to Fix / Troubleshooting

Safety first: Unplug the unit before accessing internal switches or panels.

Checks:

Confirm that time and temperature are set; some T-fal models require both before Start will work.
Remove and firmly reinsert the basket until it clicks into place.
Try pressing Start firmly and in different areas of the button in case of partial touch failure.

Internal diagnostics:

Access the touch control panel and inspect the Start button area for cracks or moisture.
Reseat the ribbon cable between the panel and main board.
Test the basket interlock switch for continuity when the basket is inserted.
If the Start button is unresponsive but other buttons work, replace the touch control panel assembly.
If multiple buttons fail or random behavior occurs, the main control board may be defective.
