Oven beeps and displays F11; some buttons may not respond or may trigger the wrong function.

Safety first: Turn off power before removing the control fascia.

Step-by-step checks:

• 1. Clean the panel: With power off, clean the glass or plastic control surface using a slightly damp cloth and mild detergent. Dry thoroughly. Avoid excessive moisture around the edges.
• 2. Check for stuck buttons: On models with physical buttons, press each key several times to ensure it moves freely. If a button is jammed, inspect for debris or misaligned fascia.
• 3. Inspect keypad cable: Remove the control panel and check the ribbon cable from the keypad to the display or main board. Reseat it and ensure no cracks or kinks.
• 4. Test after reset: Restore power and see if F11 reappears. If the same key is always reported as stuck (refer to service manual if available), the Hotpoint-Ariston keypad / touch panel is likely defective.
• 5. Replace keypad assembly: Transfer any brackets or seals from the old panel to the new one, ensuring a tight seal to prevent future moisture ingress.
