- A thorough cleaning of all the external Bunn coffee maker parts, namely the coffee pot, filter basket, and spray head.

- Using the deliming spring to loosen any lime deposits that have accumulated within the water tube.

- Running a brewing cycle with vinegar to remove coffee residue, lime and mineral deposits within the machine.

- Removing all traces of the vinegar within the machine by running multiple brewing cycles with water.

To clean your Bunn coffee maker, you will need the following:

- A toothpick
- Deliming spring (a cleaning apparatus that came with your Bunn coffee maker)
- 1 quart of white vinegar

Bunn Coffee Maker Cleaning Process

1. First, unplug the unit.

2. Let’s start with the Bunn coffee pot and filter basket. Make sure to clean these thoroughly with dish soap and warm water. When you’re done, set them aside.

3. Unscrew the water spray head. Inspect the holes of the spray head. Check if there any white flakes or mineral deposits in the holes. If these are clogged, you can clear them out with a tooth pick. Rinse the spray head with warm soapy water. Once you’re done, set it aside for now.

4. Take the deliming spring that came with your Bunn coffee maker. Insert it into the water tube, which is now exposed since you removed the spray head, six or seven inches, then apply a push and pull motion about six times. This will loosen any lime deposits that have accumulated within the water tube. If you can’t find the deliming spring that came with your Bunn coffee maker, a stiff pipe cleaner will do.

5. After that, replace the water spray head, filter basket, and coffee pot. Plug the unit back in.

6. Pour a quart of white vinegar into the water tank and do a brewing cycle with the vinegar. The purpose of this is to run the vinegar through the machine. Basically, the vinegar acts like a coffee maker cleaner, which is basically an acidic solution that removes any coffee residue and lime deposits that have accumulated within the machine

7. Once the brewing cycle is finished, pour out all the vinegar from the coffee pot. Return the coffee pot to the machine.

8. Now it’s time to remove traces of vinegar within the machine. Fill up the water tank with water and do a brewing cycle. Pour out all the water from the coffee pot once the brewing cycle is finished. Repeat this step a few more times to make sure that no traces of vinegar are left within the machine.

9. Once all traces of vinegar have been removed, allow the machine to preheat the water inside the water tank for 15 minutes before you start brewing coffee again. Your Bunn coffee maker should be as good as new.
