The top burner on our bunn coffee maker is getting to hot, causing the coffee to pop, do you have any suggestions on how to fix this problem? Please advise

Couple of ideas.

Your weak coffee could be due to the machine not getting hot enough, which is usually caused by calcium scale buildup on the heating element (the "burner").

Try descaling with a citric-acid based cleaner, such as Dezcal or Durgol.

The second is the coffee your using is a weak blend. Try changing to a different coffee and see if the strength is better.

Hello, yes you are correct, it's due to the water boiling in the tank. take 2 screws out of the top panel, just under this panel you will find the thermostat (it's ajustable) turn the temp down on the thermostat, if this does not solve the problem your thermostat may be bad and you will have to replace it. You can purchase new parts from either bunn direct or from holiday house in california. if you have any additional questions please feel free to comment again. Good Luck! Mike

Did you let the vinegar mix with the hot water in the tank for 2 hours? If this didn't fix the problem, please call 800-352-2866 with the model and date code and we will be happy to assist you with this problem.

Tammy,

Plug the coffee maker in and fiIl with water again and let it flow through. Do this several times.

I don't think household bleach would cause any damage to the unit. Industrial bleach, yes, but not household, especially if diluted with water.

Let me know what you find.

that needs to go back to bunn for a replacement tank, they will likely only charge you for return shipping

Are you leaving the machine plugged in all of the time? If not, you need to. The machine takes approximately 10 minutes to get to full temperature the first time then the water should stay hot from then on. Or it could be that you just need to turn up the thermostat. No, the water won't get hotter sitting on the burner and the coffee won't taste as good if the water you are brewing with isn't hot enough.

To get to the thermostat, unplug the machine and take the two screws on the top lid off. You should see a box that has a knob or a T sticking out of it. Turn it up a little bit, put the lid back on and let the heat up for a little while (10 - 15 minutes). Try brewing with just plain water. If it still isn't hot enough, repeat the steps above. Make sure you don't turn up the thermostat so much that the water boils.

the tank is not full. the sensor at the top is being bridged and it thinks it's full. pop it out and clean it and delime the tank.

there is an overfill tube in the rear that may be leaking.

Is the burner hot when this occurs?

Is the burner hot while your pouring water in?
