Display is on but buttons do not respond or respond intermittently.

Safety: Disconnect power before removing the front panel.

• Dry moisture: If there are signs of condensation or water on the panel, dry it and identify the source of moisture (e.g., leaks, high humidity).
• Check ribbon cable: Ensure the cable between the display and main PCB is firmly connected and not damaged.
• Test buttons: After reassembly, restore power and test each button. If some remain unresponsive, the interface board may need replacement.

Note: Use only genuine Immergas replacement panels to ensure compatibility.
