Microwave beeps and shows E08; keypad or touch controls may be unresponsive or behave erratically.

Safety first: Disconnect from mains.

• Dry and clean: If the error appeared after steam or liquid spilled near the controls, leave the microwave unplugged for several hours to dry. Wipe the control area with a dry cloth.
• Check ribbon cable: Remove the control panel assembly and inspect the flat ribbon cable between the keypad and main PCB. Reseat the cable and ensure it is not creased or damaged.
• Inspect keypad: Look for signs of delamination, bubbling, or physical damage on the membrane keypad. Sticky keys or permanent activation indicate failure.
• Replace keypad or control module: If individual keys do not respond or E08 persists, replace the keypad membrane or the entire control panel module with a Zanussi-compatible part.

Do not spray cleaners directly onto the control panel; apply to a cloth first to prevent future moisture damage.
