Keurig coffee maker troubleshooting

Keurig coffee makers are a line of brewers that have a one-cup system in place. Instead of using a coffee filter and grounds to make coffee, the systems employ the use of K-Cups. The K-Cup is placed inside of the machine and you simply press "Brew" to make your coffee. The K-Cup is disposed of after use. If you have a Keurig coffee maker and run into an issue, you can perform these troubleshooting techniques.


If you have high mineral content in your water, scale can build up inside of your Keurig coffee maker and affect performance. Scale can block the heating element of the Keurig brewer and interfere with heating up the water. Keurig brewers have sensors that let you know when scale has built up and "Descale" will appear on the display of the unit.

To descale, you need just over 1.3 litres (48 ounces) of white vinegar and a ceramic cup. You'll start by emptying the reservoir of the Keurig machine. Replace the water with the vinegar. Make sure the K-Cup holder is empty and then start a brew cycle. Place a ceramic cup under the spout to collect the vinegar. Empty out the contents into the sink. Repeat this process until the vinegar is emptied from the water reservoir. Refill with water and run several brew cycles before use in order to rinse the unit.

Coffee maker will not brew

Check the power source to make sure the unit is plugged in securely and that the outlet is working properly. You may need to reset the circuit breaker if the Keurig maker will not turn on.

Lift the K-Cup holder handle up and down onto the single portion pack. Make sure the handle is secure, and that the unit reads "Ready to Brew" on the LCD display. Review the LCD display as well for any error messages, such as "Add Water." Fill the water reservoir to resolve this issue.


Your Keurig brewer may not function correctly if any of the parts become clogged and require cleaning. For instance, the exit needle may become inoperable due to lodged coffee grinds. Use a paper clip to loosen the grinds and push them through the spout.

The funnel of the Keurig coffee maker can be snapped out of the machine and placed in the dishwasher for cleaning. The water reservoir can be cleaned using soapy water and a clean cloth in the sink by hand.
