How to Fix / Troubleshooting
Safety: Turn off power before disconnecting any control cables.
- Power cycle: Turn off the boiler at the main switch for 30 seconds, then turn it back on to clear a temporary software lockup.
- Inspect connections: Remove the front panel and check the ribbon cable or plug between the display and main PCB. Reseat firmly.
- Check for moisture: Look for condensation or water behind the display. Dry carefully and address any leaks from above.
