How to Fix / Troubleshooting
Safety: Disconnect power at the breaker before accessing the control compartment.
- Inspect control board area: Remove the front panel and look for signs of water leaks above the control board (from piping, relief valve, or condensate). Correct any leaks before proceeding.
- Check connectors: Gently press on all multi-pin connectors to ensure they are fully seated. Do not force them.
- Verify supply voltage: Use a multimeter (if qualified) to confirm the boiler is receiving the correct voltage specified on the Crown rating plate.
- Reset: Restore power and attempt a reset. If E14 reappears, the control board likely needs replacement by a qualified technician.
