So, let’s dive in and shed some light on the mystery of Keurig flashing lights!
1. Descale Light: Cleaning Reminder
One of the most common reasons for Keurig flashing lights is the descale light. This indicator serves as a reminder that your Keurig machine needs to be cleaned to remove mineral deposits that can affect the taste and performance of your coffee. Descaling is recommended every three to six months, depending on the frequency of use.
To descale your Keurig, follow these steps:
- Prepare a descaling solution by mixing it with water according to the manufacturer’s instructions.
- Empty the water reservoir and pour the descaling solution into it.
- Place a large ceramic mug on the drip tray.
- Start the brew cycle without inserting a K-Cup, selecting the largest cup size.
- Discard the hot solution in the mug and repeat the brew cycle until “Add Water” is displayed.
- Rinse the water reservoir thoroughly and refill it with clean water.
- Repeat the brew cycle without a K-Cup to flush out any remaining descaling solution.
By descaling your Keurig regularly, you can prevent clogs and maintain the optimal performance of your coffee machine.
2. Add Water Light: Water Tank Issues
If your Keurig is flashing the “Add Water” light, it indicates a problem with the water tank. The light serves as a reminder to fill the tank to the appropriate level for brewing. However, sometimes the light may persist even when the water tank is adequately filled.
Here’s what you can do to troubleshoot this issue:
- Check for any debris or dirt that might be obstructing the water tank’s sensors. Clean the area thoroughly to ensure proper functionality.
- Verify that the water tank is correctly positioned and securely seated on the brewer. Misalignment can trigger the “Add Water” light.
- If the above steps do not resolve the issue, inspect the water outlet needle for any clogs. Use a paper clip or a small needle to clear any blockage that may be preventing water flow.
By addressing these water tank-related issues, you can ensure uninterrupted brewing with your Keurig machine.
3. All Lights On: Outlet Needle and Carbon Filter Problems
When all the lights on your Keurig machine are flashing simultaneously, it indicates potential issues with the outlet needle or the carbon filter.
Follow these troubleshooting steps to address these problems:
- Begin by cleaning the outlet needle. Start by removing the K-Cup holder and inspecting the needle for any clogs or buildup. Use a paper clip or a small needle to gently clear any blockage. Ensure the needle is free from any debris before reassembling the K-Cup holder.
- If the problem persists, check the carbon filter. Remove the water reservoir and locate the carbon filter at the bottom. Remove the filter and rinse it under running water for a few seconds. Reinsert the filter and ensure it is properly positioned.
Thoroughly cleaning the outlet needle and checking the carbon filter can resolve the “All Lights On” issue and restore normal operation to your Keurig.

- Unplug the Keurig machine from the power source and wait for a few minutes.
