Charger error codes: what do they mean?

Error on the charge point – where to start?

Charge points usually communicate problems using a numeric error code or LED colour patterns. Leafy Energy can often read and translate these codes.

Typical error categories

• Network error: charger has no connection to backend or internet.
• Car communication error: car and charger cannot negotiate a session.
• Hardware fault: internal relay or cable sensor reports a problem.
• Authorisation error: charge card or app token is rejected.

How Leafy Energy helps

• The session details show the error code and, where possible, a human-readable explanation.
• We link to known fixes or the manual for your charger brand.
• For demo purposes, you can simulate fictional error codes with descriptive messages.

For recurring errors we recommend exporting charger logs and sharing them with your installer or hardware vendor.
