ISSUE: Short cup, slow dripping, or no coffee
POSSIBLE SOLUTION: The exit needle is blocked with coffee grounds. This can occur if a person removes the lid from a k-cup and then tries to brew, or if the K-Cup was not properly sealed at the factory. The grounds can get clogged in the tiny exit needle and cause the brewer to give a short cup or no coffee. To remedy this, the user can remove the K-Cup "holder" from the brewer and thoroughly rinse with warm water from both the top and bottom sides. This should normally cure the problem. If the needle is still blocked, compressed air may be used.
ISSUE: Brewer will not start the brewing process, there is low pressure, or not filling cups to the top
POSSIBLE SOLUTION: Some of the brewers sold from the end of 2009 into the late spring of 2010 had pump issues. Please contact Keurig at 1.866.901.BREW (2739) or check your warranty, because Keurig will replace these defective models.
ISSUE: Descale Light is on
POSSIBLE SOLUTION: This indicates that the coffee brewer has a build up of mineral deposits that may affect the proper brewing cycle. The brewer may continue to function normally for a while, but should be descaled. To fix this problem:
1. Empty the water reservoir.
2. Fill the reservoir with white vinegar.
3. Place a ceramic cup (not paper) on the drip tray. DO NOT put a K-Cup in the brewer.
4. Press brew button (you may need to open and close the lid).
5. Empty the contents of the cup into a sink.
6. Repeat until the reservoir is empty.
7. Rinse reservoir and fill with clean water.
8. Let brewer stand for 4 hours while turned on (vinegar is now in tank).
9. Again place empty ceramic cup on drip tray. DO NOT put a K-Cup in the brewer.
10. Press the "BREW" button and empty contents in a sink.
11. Repeat until Reservoir is empty (this will drain out the vinegar).
12. Descale light should now be off.
