How to Fix / Troubleshooting
Safety first: Work on power circuits only if you are qualified.
- Check power plug and outlet: Ensure the plug fits firmly and the outlet is not loose.
- Use surge protection: Install a surge-protected power strip or dedicated surge device for the BWT Perla.
- Avoid shared circuits: Do not share the circuit with heavy inductive loads (e.g., large pumps) if possible.
- Firmware reset: Perform a factory reset if recommended by BWT support to clear potential software glitches.
- Replace PCB if unstable: If restarts continue despite stable power, the internal power supply or microcontroller may be defective and the main PCB should be replaced.
