Possible Causes
Low or high supply voltage, Loose neutral or earth connection, Shared circuit with heavy loads causing dips, Faulty power supply section on control board
How to Fix / Troubleshooting
Safety: Electrical work must comply with local regulations. If you are not qualified, contact an electrician.
- Measure voltage: With a multimeter, measure the mains voltage at the furnace terminals. Compare to the range on the Viadrus rating plate (typically 230 V ±10%).
- Check connections: Tighten terminal screws for live, neutral, and earth in the furnace connection box. Inspect the supply cable for damage.
- Dedicated circuit: If the furnace shares a circuit with large motors or appliances, consider moving it to a dedicated circuit to avoid voltage dips.
- Surge protection: Install a surge protector or voltage stabilizer if your area has frequent fluctuations. If E17 persists with correct voltage, the internal power supply on the control board may be faulty and require board replacement.
