Possible Causes
Failed BWT display/keypad board, Moisture ingress into control panel, Damaged ribbon cable between UI and main board, Firmware lockup
How to Fix / Troubleshooting
Safety first: Turn off power before opening the control panel.
- Power cycle: Turn off the breaker for 5–10 minutes, then restore power to clear any temporary lockup.
- Inspect panel for moisture: Remove the front panel and check for condensation or water inside the display housing. Dry thoroughly and correct any sealing issues.
- Check ribbon cable: Ensure the cable between the user interface and main PCB is firmly seated and not damaged.
If the interface remains unresponsive, the display/keypad board is likely defective and should be replaced with a BWT-compatible part.
