How to Clean a Bunn Coffee Maker

Bunn coffee makers are particularly popular since they may be used in both commercial and domestic settings. It is essential to keep your coffee maker clean and free of germs to create good coffee. Maintaining your coffee maker’s cleanliness can also help it last longer.

Keeping a Bunn coffee maker clean requires more than just wiping down the exterior. If mineral deposits form in the water tank or spray head tube, the brewing process will trickle.

There is a unique tool included with Bunn coffee makers that make cleaning the spray head simple.

All you need to clean the water tank is a lot of white vinegar, and dish soap will do the trick on the coffee maker’s exterior.

Standard Cleaning Method

Step 1: Turn The Machine off

The normal cleaning procedure for your Bunn coffee machine is outlined below. This should be done every time you use your device, whether once a day or whenever.

Step 2: Remove Coffee Grounds and Coffee Filter

Do not begin cleaning until the machine has been unplugged. To avoid electrocution, you must do this step. During the cleaning procedure, you’ll be using water, and that water may still be in the carafe or machine.

If you’re using a filter, toss it out with the coffee grounds. Then, run water through the filter to remove any lingering dirt.

Step 3: Wipe Down The Exterior

Dip a soft towel in warm water that has been diluted with a little amount of unscented or faintly scented dish detergent before you begin cleaning. Clean the machine’s exterior using a damp cloth.

After that, wipe your gadget down with a clean, moist towel to eliminate any soap residue that may have remained.

Step 4: Clean and Soak The Carafe

The carafe sometimes has brown rings inside of it. This is very normal and can easily remedy by soaking in soapy water for a while.

Wipe inside the carafe with a washcloth before adding warm, soapy water. Allow it to rest for a few hours before rinsing and drying.

Note: Dishwasher, baking soda, or vinegar solutions are all options for cleaning the carafe.

Step 5: Clean The Spray Nozzle

Most coffee makers come with a sprayer that squirts water into the cup. Examine the spray head for clogs by disassembling it.

The mineral coating or coffee grounds can be scraped off with a toothpick or other tiny instrument. After that, wash the nozzle with warm water and mild dish soap before wiping it clean with a cloth.

Step 6: Clean The Spray Tube

The spray tube on some Bunn models can be cleaned with a plastic or metal tool included with the sprayer.

To begin, take off the brew strainer and spray nozzle from the bottle and discard them. Once this is done, slowly rotate the cleaning tool while pushing it up and down the tube.

Connect the brew funnel and reattach the spray nozzle when all deposits have been removed.

Clean Bunn Coffee Maker With Vinegar

Pour Vinegar

Four cups of vinegar will be poured over the top. Please make sure the carafe is under the coffee maker before you start using it.

Empty The Carafe

Now that the carafe is empty, you can unhook the power plug and switch off the machine.

To use the Bunn coffee maker, add vinegar to the water reservoir. When the vinegar spilled into your water tank, it pushed the water to the outside. These are your hands after rinsing with this water.

Let Vinegar Work

Vinegar will do its magic now that you’ve added it to the tank of water. As a result, please be patient for two hours.

Remove The Nozzle

After two hours, you’ll be able to remove the Bunn coffee maker’s nozzle. The print head is really hot, so don’t try this sooner.

Clean Minerals

You can now inspect the nozzle to check if it has mineral deposits. Toothpicks come very handily in this situation. You’re welcome to peek inside and see what’s going on. Use soap and water to clean.

Filled With Fresh Water

It’s time to add fresh water to the Bunn coffee maker. Pour water into a carafe and set it aside. However, do not forget to set up the brewing funnel.

As soon as the carafe is in place, close the top and wait for the rinse to begin.

Rich Rinse

In a hot water tank, you’ll get a lot of vinegar. This procedure must be repeated roughly four times or until no more vinegar odor can be detected.

This will happen shortly, and you might even notice some hard-stacked little bits inside of the coffee machine.

Now you can get rid of it and clean the space. You’ll have to repeat this process four or five times before you no longer detect vinegar smells.

Replace The Nozzle

That means it’s time to get a new nozzle. Set the sprinkler back in its place after removing the brewing funnel.

Reconnect the Bunn coffee maker, plug it in, and then open the brewing funnel. This is what needs to be done by you. Take about 15 minutes for the water to come to a boil before you begin using it.

Four cups of vinegar will be poured over the top. Please make sure the carafe is under the coffee maker before you start using it.

Deep Cleaning Method

Descale your coffee maker if you haven’t done so recently. You may have no idea what I’m talking about. This is a judgment-free zone, so relax!

Choose between bottled water, filtered water, mineral water, or plain old tap water as your beverage of choice.

Calcium and magnesium deposits will form on the inside of your machine over time. Descaling is the process of getting rid of “limescale,” a powdery buildup on surfaces.

Heat causes thick oxide coatings to build on the minerals in the water, decreasing water flow, impairing the flavor of your coffee, and dangerous machinery over time.

Problems with heating, clogging, or a bad cup of coffee (after waiting so patiently for it to brew) are all possibilities.

Even while deep cleaning should not be done daily, you should aim to do it every three months if you use your coffee maker frequently.

How to deep clean your Bunn coffee maker is as simple as following a few simple steps.

Step 1: Mix Your Solution

Put roughly 1/2 to 1/3 cups of vinegar and 12 to 23 cups of distilled water in a dish and stir them together.

Step 2: Start Your Brew

Fill the water reservoir with a mixture of vinegar and distilled water. After that, you can begin the brewing process.

Turn off the coffee machine and let the carafe fill up with water. Then, remove the solution and pour it out.

To effectively remove limescale from the interior, let the solution soak for about two hours in the reservoir.

Step 3: Wipe Down the Spray Nozzle and Tube

Use a toothpick or other tiny tool to remove any deposits built up on the sprayer’s nozzle after it has been unscrewed.

After that, run warm water over the dish to remove the soap. Use your metal or plastic deliming tool to clean the spray tube according to the above recommendations.

Step 4: Start Brew #2

Put everything back together again (spray head and spray tube). Start the machine and add distilled water to the reservoir. Continue to brew for a second time.

This will get rid of whatever vinegar smell the solution may have left behind. Repeat this procedure as necessary until you no longer detect any odor.

Descaling a Bunn Coffee Machine

Cleaning the equipment via descaling removes mineral and hard water deposits. Particularly in places with hard water, it should be completed at least once each week. Follow the steps outlined in the following paragraphs:

Step 1: Mix Vinegar with Distilled Water

Fill a coffee pot to the brim with a solution made of white vinegar and distilled water. Be sure to split the vinegar and purified water in half before mixing.

Step 2: Start a Brewing Cycle

Start the brewing cycle after adding the descaling solution to the water reservoir. This will allow the combination to clean out the coffee maker of lime and mineral deposits.

Step 3: Discard the Brewed Cleaner

Dispose of the brewed descaling solution after the pot is full.

Step 4: Clean The Spray Head and Fittings

Unplug the coffee maker from the plug socket and turn it off. After that, wash the spray head and any exposed fittings with warm, soapy water.

Remove the spray head and clean the open holes using the spray head cleaning tool’s pointed end. After that, clean the spraying head and bypass connections with the tool’s long head.

Step 5: Perform Rinse Cycles

Then, reconnect the machine’s power cord and reattach the spray gun’s spray head. Restart the device and add distilled water to the reservoir by filling a pot halfway with distilled water and pouring it in.

The descaling solution’s aromas and flavors should be removed by starting another brew cycle. If required, repeat the process until the smells have disappeared.
