How to Fix / Troubleshooting
Safety first: Repeated interruptions can indicate overheating or loose connections that may lead to fire.
- Check cable and plug temperature: During charging, periodically touch (carefully) the cable and plug. If they are uncomfortably hot, stop using the charger and have it inspected.
- Inspect plug fit: Ensure the connector fully seats into the vehicle inlet with a solid click and no wobble.
- Monitor other loads: Large appliances starting (e.g., heat pumps) may cause voltage dips. Consider staggering usage.
- Professional tightening: An electrician or technician should open the Webasto unit and retorque all power and pilot terminals to specification.
