Q: Charger not working

Hi Jodie

Check that the back of your Apple Watch and the concave head of the charging cable are each clean and dry (clean them with a lint-free cloth and retry).

Check also that you are following the charging instructions here:

Check your battery and charge your Apple Watch - Apple Support

If the issue persists, contact Apple Support (mail-in service may be available) or make a Genius Bar reservation with a view to having your watch and/or power accessories  checked under warranty.
