Why is my Tesla wall connector flashing red and not charging?

A flashing red light on your Tesla Wall Connector typically indicates a fault or communication error. Here are the most common causes:

Common Issues: - Power supply problem — Check if the breaker controlling the charger has tripped. Reset it if needed. - Loose connections — The electrical connection behind the Wall Connector might be loose. This needs a qualified electrician. - Overheating — The unit may have shut down due to high temperatures. Let it cool and try again. - Firmware glitch — Try power-cycling the unit by turning off the breaker for 10 seconds, then back on. - Ground/safety fault — The charger detected a grounding issue, which is a safety feature.

What to do: 1. Check Tesla's support documentation or scan the QR code on the charger for specific error codes 2. Verify your vehicle isn't showing related error messages 3. If the issue persists, you'll need a licensed electrician — especially if it involves wiring, breaker, or grounding problems

When to call an electrician: Don't attempt DIY fixes beyond simple breaker resets. Wall Connectors involve 240V circuits and require professional diagnosis if basic troubleshooting doesn't work.

You can use electrician.city to find local licensed electricians experienced with EV charging installations. Many can diagnose Wall Connector issues quickly and safely.

In the meantime, if you need to charge urgently, you can use a standard outlet (very slow) or a public charging station.
