How to Fix / Troubleshooting
Safety: Turn off power at the breaker before removing the front panel.
Steps to address F10:
- Inspect the display panel: Remove the front bezel or cover to access the user interface (UI) board. Check for signs of moisture, corrosion, or physical damage.
- Check harness connections: Reseat the ribbon cable or harness between the UI and main control board. Ensure connectors are fully latched.
- Dry moisture: If condensation or water is present, gently dry the area with a lint-free cloth and allow the unit to air dry completely before restoring power. Identify and correct any source of leaks above the heater.
- Power cycle: Restore power and see if the F10 code clears and the display responds normally.
- Replace boards as needed: If the UI remains unresponsive or F10 persists, replace the user interface board first. If the issue continues, the main control board may also need replacement.
Tip: Take photos of wiring before disconnecting to ensure correct reassembly.
