How to Fix / Troubleshooting

Safety: Turn off power before removing the front panel and accessing the display.

  • Check connections: Reseat the ribbon cable or connector between the main control board and the display module.
  • Inspect for damage: Look for signs of moisture, corrosion, or burn marks on the display PCB.

If the display remains unreadable, the display module or main control board may need replacement by a technician. Do not operate the boiler without a functional display, as you cannot see error codes or settings.
