There's a few troubleshooting steps you can try when the Ember is not powering on
First, check the charging coaster. The pins on the coaster should be able to spring back up and remain at even heights. If one or both pins seem to be recessed or uneven, your Ember and Charging Coaster are not receiving a constant connection, therefore will have some issues charging or powering on. If this is the case, please reach out to us at support@ember.com
If the coaster looks good, let's try a reset of the Ember. We will be performing a reset of your mug to recalibrate all data that can potentially be causing the issue. To do this, press a paperclip in the reset pinhole on the bottom of the mug for about 10 seconds. The Ember will display "RESET" then "HELLO" to indicate the reset was completed.
