I put my Apple Watch to charge over night, when I woke up it was extremely hot and would not turn on. I let it cool off and tried to restart it and still wouldn’t work. I tried putting on a different charger and it would not charge.
Here's Apple's guidance for what to do if your Apple Watch won't charge or turn on. If none of that works and you still need help, contact Apple Support.
Hope you are able resolve this.
