Apple Watch series 3 won’t charge, even after a restart and cleaning of Watch back.

Hello Baxmkk,

Does that persist if you force restart your Apple Watch? Restart your Apple Watch - Apple Support

Are you able to try charging with another cable, power adapter or wall outlet?

Should that still continue, you'll want to reach out to Apple Support so they can look into this further: Contact - Official Apple Support

Take care.

My Apple Watch Series 3 was working fine this morning. Mid afternoon I tapped on the screen to check the time and nothing happened. I hit the button on the side and the crown and got the Apple logo and that’s it. I also took a picture of another image I saw on my watch. I’m bringing my watch to the Genius Bar this week

Hello Baxmkk,

We're glad to hear you found the issue and your watch is working as it should now.

Have a great night!
