The Keurig flashing light code is a code that the manufacturer provides to aid in troubleshooting issues with the coffee maker. The different beeping codes that the Keurig may emit include:
-Empty water reservoir: The flashing light will stay on and the coffee maker will continually make a low beeping sound until the reservoir is refilled.
- descaling: This occurs when undissolved substances collect on the internal parts of the coffee maker. To descale your Keurig, empty all of its water, put fresh water into the reservoir, and push the brew button five times quickly.
-Not connected to power: If you have lost power to your Keurig, it will enter safe mode where it will not make any noise or produce any heat. In order to return to normal operation, you'll need to reconnect the power and wait a few minutes for it to reset.
