How to Clean a BUNN Coffee Maker

Cleaning a BUNN Coffee Maker is essential to maintain its performance and ensure a great cup of coffee. The process involves disassembling the coffee maker, cleaning the filter basket, sprayhead, and sprayhead tube, descaling with a vinegar-water solution, running cleaning cycles, and rinsing thoroughly and gently. Regular maintenance, such as using filtered water and replacing the coffee filter, is also recommended. By following these steps and tips, you can keep your BUNN Coffee Maker in top shape and enjoy delicious coffee every time.

Step 1: Unplug and Disassemble the Coffee Maker

To begin, make sure your BUNN coffee maker is unplugged and cool to the touch. Remove any remaining water from the reservoir and discard the used coffee grounds. Carefully detach the carafe and the filter basket.

Step 2: Remove and Clean the Filter Basket

Take out the filter basket and wash it with warm, soapy water. Use a toothbrush to gently scrub away any stubborn residue. Rinse it thoroughly and set it aside to dry.

Step 3: Clean the Sprayhead and Sprayhead Tube

Locate the sprayhead, which is usually on top of the coffee maker. Use a soft cloth or sponge dampened with a vinegar-water solution (equal parts) to wipe away any coffee stains or residue. If the sprayhead is removable, detach it and clean it more thoroughly. Use a toothbrush to reach any hard-to-reach areas.

Next, inspect the sprayhead tube for clogs. If you notice any blockages, gently clean the tube using a small brush or a toothpick. This will ensure a steady flow of water during the brewing process.
