Hard Reset the Ember Mug

A soft reset will solve the problem in some cases, but if it doesn’t help you, then you might want to try a hard reset. A hard reset will return the Ember Mug back to its factor settings which will clear out any software issues that is, preventing the device from charging.

To perform a hard reset;

  • Press and hold the power button on the base of the mug for 10 or more seconds.
  • The LED light will blink blue, yellow, and then red to indicate the mug is being reset
  • Once you see all three colors, let go of the power button
  • Wait till the LED pulses back to white to confirm that the reset is successful

If you own an Ember Travel Mug, the process to a hard reset is just the same as the regular Ember Mug, however, there are slight differences.

  • Place a paper clip into the hold on the bottom of the mug until you hear a click
  • Hold for up to 10 seconds until the Ember displays “RESET” and then “HELLO”. This means the reset was successful.

Check if the Charger is Broken

A charging problem could be due to the charger of the device rather than a software issue. This is common with the Ember Mug and it could be one of the toughest problems to fix. The problem here is that the prongs on the charging coaster could get stuck in a depressed position. When this happens, the Ember Mug will not be able to charge.

To fix this problem, you could turn the coaster upside down and charge the Ember Mug upside down. This will work in some cases. A better option will be to check the warranty. If your mug is still within the 1-year window, you could be able to get a replacement charger at no extra cost.

If not, then you will have to spend on a replacement charger. Keep in mind that the Ember Mug is quite expensive so the charger won’t come cheap. You might want to consider purchasing a brand new Ember Mug that comes with the charging coaster if the cost is too high. You could keep the old coaster for parts and save yourself some extra costs in the future.

Sometimes charging problems can be resolved by charging the Ember Mug properly.
