Error Code 2

What Does Error Code 2 Mean?

Error code 2 is a prevalent issue with the K-Supreme coffee maker. The display typically shows: “Error code 2, Please wait a few minutes and then try brewing again.”

This error occurs when the heating element inside the Keurig malfunctions, causing the preheating tank to drain and overheat due to insufficient refilling.

How To Fix It?

First, follow the on-screen suggestion by unplugging the coffee maker and waiting for approximately 10 minutes. Then, plug it back in and switch it on.

If this does not resolve the issue, the TCO (thermal cut-out) has likely failed. Similar to a fuse, it pops and needs replacement when damaged. If you’re not really a handyman yourself, it’s advisable to contact Keurig customer service to discuss a replacement coffee maker.

Error Code 11

What Does Error Code 11 Mean?

Error Code 11 is also a common issue with the K-Supreme Brewer indicating an insufficient water issue. There are a few different ways to fix this problem.

This problem is usually caused by the lid creating a vacuum seal that prevents water flow.

How To Fix It?

Get Rid of The Vacuum Problem

  1. Remove the lid from the water tank to see if it resolves the issue.
  2. Thoroughly dry the water tank lid and the rim of the tank. Water droplets between the tank and cap may increase the likelihood of a vacuum seal forming.
  3. If you’re comfortable with this method, drill a small hole in the tank lid to alleviate the vacuum seal issue. Proceed with caution and only do this if you’re confident in your ability to modify safely.

Fix The Water Filter

Another thing that can cause this issue is the water filter attachment. Remove the water filter attachment and run a cup of hot water to confirm if it resolves the issue. If it works, replace the actual filter with a new one.

Get The Float Mechanism Unstuck

Additionally, the float mechanism (which indicates the water level to the appliance) might be jammed.

To fix this issue, remove the water tank and gently shake it until the floater becomes unstuck. Be sure to clean the floater and the rest of the water tank afterward to prevent it from getting stuck again in the future.

If none of the above worked, the last thing you could try is to reach out to Keurig Support to report the problem. If you’re within warranty, they’ll probably send you a replacement unit.

While there is no definitive solution to Error Code 11 on your Keurig, these troubleshooting steps may help resolve the issue.

Error Code 8

What Does Error Code 8 Mean?

The Keurig manual states that error code ‘8’ occurs when the thermistor in the preheat tank detects a temperature above 240°F. Possible causes include issues with the thermistor or the heater triac.

How To Fix It?

To resolve this issue, follow the on-screen instruction: “Please unplug and replug the brewer.”

However, after unplugging the machine, allow it to cool down for approximately an hour before plugging it back in. This will give the Keurig coffee maker ample time to cool and potentially fix the problem.

Error Code 9

What Does Error Code 9 Mean?

Error code 9 displaying is a common issue with the K-Cafe. This error code is usually caused by air bubbles in the tubes.

How To Fix It?

  1. Ensure there is water in the reservoir: Make sure your machine has enough water in the reservoir before attempting to fix the error.
  2. Unplug and replug the machine: Unplug your Keurig Cafe machine for a moment and then plug it back in.
  3. Press the 12-ounce button and the K-Cup button simultaneously. Hold them down until the machine powers off.
  4. Press the 12-ounce button and the K-Cup button again, holding them down as before. The machine will power on and start draining water through the reservoir pump.
  5. Keep holding the buttons to force out any air bubbles in the line. You can do this for as long as you’d like or until the entire reservoir empties. Holding the buttons for around 30 seconds should be sufficient.
  6. When you’re done pushing the air bubbles out, release the buttons.

Now try brewing a coffee. Make sure there’s enough water in the reservoir, insert your K-Cup, choose the desired size (e.g., 8 ounces), and press the K-Cup button. Your machine should now work without displaying error code 9.

Error Code 17 Overpressure Detected

  2. Turn the machine on its back to access the lid and open the lid and locate the needle that punctures the K-cup during brewing.

  4. Using a paper clip or similar pointy object, gently insert it into each hole. Wiggle and rotate the paper clip to loosen any coffee grinds or scale buildup.
  5. Reassemble the coffee machine by plugging it in and reattaching the water reservoir.
  6. Turn on the machine and wait for it to heat up; the error code should be resolved.
  7. Press the brew button to flush out any remaining debris before brewing a cup of coffee.
