What Does Error Code 2 Mean on Keurig?

Error Codes 2, 8, 9, 11, etc On Keurig

Error code 2 is a common problem with the K-Supreme coffee machine. Usually, the display states: “Error code 2 Please wait a few minutes before attempting to brew again.”

This error occurs because the heating element within the machine does not work. As a result of insufficient refilling, the preheating tank dries and overheats.

How to Fix it?

First, you need to follow the suggestion that the machine is showing on the screen, which is to unplug the device and wait for about 15 minutes, then plug the machine in and switch it on.

If that does not work, TCO (thermal cut-out) will likely break down. When it is damaged, it pops like a fuse and must be replaced. If you cannot do it yourself or are not a professional, then you can contact any technician or Keurig customer service for the replacement of the TCO.

Error Code 11

What Does Error Code 11 Mean on Keurig?

Keurig error code 11 is also a regular problem with the K-Supreme Brewer, suggesting a lack of water. This issue has numerous fixes.

Usually, this problem happens when the lid creates a vacuum seal that stops the water flow.

How to Fix it?

Getting Rid Of The Vacuum Problem

  • Clean the water tank lid and rim carefully. The presence of water droplets between the tank and the cap may enhance the possibility of a vacuum seal developing.
  • If you want to do this procedure to solve the vacuum seal problem, drill a tiny hole in the tank lid. Proceed carefully and only if you’re confident in your ability to carry out the changes.

Fix The Water Filter

The water filter attachment is another reason that causes this issue. In order to solve this issue, take out the water filter attachment and try running a cup of hot water to see if this fixes the problem. If it succeeds, replace the original filter with a fresh one.

Get The Float Mechanism Unstuck

Furthermore, the system of floats (which shows the water level of the machine) might be clogged.

In order to solve this issue, take out the water tank from the machine and gently jiggle it until the floater frees itself. Remember to clean the water tank and the floater to keep it from getting stuck again in the future.

If any of these tricks do not work, try contacting  Keurig Support for further assistance. 

Although there is no conclusive recovery for Keurig Error Code 11, these troubleshooting procedures may assist in resolving the problem.
