Most likely a power issue. Check the outlet first. Plug the brewer directly into its own grounded outlet. Don't share a circuit with other appliances.
Fix it:
- Press the power button to turn it on. It shuts off automatically after 5 minutes of inactivity.
- If nothing happens, unplug it and plug it into a different outlet by itself.
If that didn't work, the internal circuit might be overloaded. Unplug the brewer, wait 30 seconds, then plug it back in and press the power button. If it still has no power, the unit needs service. Contact Keurig Customer Service.
Heads up: For any electrical repairs, this brewer is not user serviceable. Don't try to open it.
