How Does a Bunn Coffee Maker Work

For millions of people, kickstarting a day should include drinking their ever-favorite morning beverage – coffee. There are lots of local coffee shops, sure! However, nothing exceeds the comfort, cost-efficiency, and quality blend of a homemade coffee. Thanks to coffee brewers. You can use the beans you like and either leave it bare or add flavorings.

Perhaps you’ve been wondering how your Bunn coffee pot heats up so fast. What is that babbling noise all about during its operation? Let’s take a look inside it, so you get a better understanding of what exactly happens whenever you make a cup of coffee.

How Does a Bunn Coffee Maker Work?

You’ll usually find three things upon taking the top off this device. Firstly, there is a Reservoir that stores water and a Filter cup that accumulates ground coffee. Moreover, you will also find a Collector cup that stores brewed coffee. The heating element inside has two jobs. First is (clearly) heat water to boiling, and second, keep the blend warm when it’s prepared.

Working of Bunn Coffee Maker

You will find it more comfortable and fun preparing a hot beverage at hand. Here are the proper ways to set up your Bunn coffee pot.

Step 1: Stock the tank up with cold water. It mainly takes around 15 minutes for the water in the reservoir to heat before the initial serving. The water will begin flowing in the collector cup once it tops up the reservoir.

Step 2: Start developing coffee by gently pouring ground coffee in the coffee filter. Make use of a spoon. Ensure to shake the coffee filter first. It will foil the ground coffee from sticking to it. Hence, promoting a uniform spread.

Step 3: Switch on the button to begin the brewing process. The water in the reservoir should trickle in the collector cup through the coffee filter cup. Besides, the brewing time ranges from three to five minutes. Though, it usually hits the three-minute stretch of time.

Step 4: Turn off the switch when the coffee is fully brewed. Pour the liquid into your cup, and don’t forget to share its delicate taste with your friends or family!

Why is my Bunn Coffee Maker Making Weak Coffee?

Does it take too long for your coffee to brew? The reasons vary. It is crucial to understand the symptoms and causes directly to prevent further issues. Below are the possible causes of a weak brewing process:

1. Incorrect Grind

Some people merely grind the coffee and go, which should not be the case. You are only disrupting your morning cup of coffee. Why? Various grind sizes act inversely in the coffee pot. The best grind size relies on the type of filter system the machine has. In the Bunn coffee maker, you should only use an adequate amount of fine grind. It ensures appropriate extraction and flavor profile.

2. Inappropriate Filter Paper

Keep in mind that your choice of filter paper also affects the overall taste of your coffee. It condenses the amount of fines (small bits of ground coffee) in the cup. It also eradicates the oils contained. You may be tempted to use another sort of filter paper. To implement a clean brewing process, though, you should use one provided by the company. For instance, the Bunn OEM filter paper is ideal for commercial coffee pots.

3. Inaccurate Water Temperature

Bunn coffee makers are designed assuming that you are using cold water. In that case, you have to supply the reservoir with cold water, nothing else. It dramatically affects the extraction process. Low extraction gives a tasteless, frail brew while over-extraction makes your coffee slush. The machine needs to have a temperature rating of 195° F or above. Having less may end up your blend tasting slightly bitter.

4. Water Clog

After the water heating, does the coffee pot remain vacant? You’re likely dealing with a water clog. It prevents the liquid from streaming through effortlessly. Good thing, it is relatively easy to fix. The water you are using may also contribute to this problem, especially in your coffee flavor. It must be fresh and sterile by look, smell, and taste.

5. Malfunctioning/Filthy Sprayhead 

Sprayhead is an essential component in Bunn coffee machines. It indicates the overall time for the water to pass. Moreover, it also shows how long the coffee grounds will be in interaction with water. You will know it’s in bad shape if the ground coffee is not getting moist inside the funnel. You have to keep the spray head clean. Consider replacement when it gets broken.

6. Mineral Buildup

Mineral deposits and accretion are regular for coffee makers. They typically occur due to the elements included in water, such as lime and calcium. The oil content in coffee granules is also the main culprit. In such a case, your coffee pot will have difficulty heating the water while brewing. Mineral buildup affects how you enjoy sipping a cup. It alters the taste and smell of your brewed blend. It may not be hot enough to drink. Worse, your unit can be in deep trouble. Cases of clogged water flow are prevalent in this case.

Bunn coffee brewers make a great companion both in the office and home. You can have your favorite beans to stay awake or treat yourself from long, tiring work. As the rule of thumb, always keep it clean and bacteria-free. Not only will it make luscious coffee, but it will also ensure long-term use. Wash the coffee maker and coffee pot after each use. Moreover, it will help if you also clean the thermal carafe. Perform a thorough cleaning of the whole unit every three months.

Bunn Coffee Maker Troubleshooting & Cleaning Tips

  1. The Brew Lockout might be enabled if the temperature doesn’t heat up after a few minutes. So, disable this function by checking the manual. For on/off switch issues, check the switch itself.
  2. Unplug the Bunn coffee brewer before cleaning. It is for safety purposes.
  3. Wash manually using warm water, mild dish soap, and a soft cloth. Do not use a coarse scrubber. It will leave a scratch on the stainless steel or glass carafe.
  4. Use vinegar for removing stains on the glass coffee pot. Scrub all sides with a soft cloth. White vinegar is mostly useful as it infiltrates the hot water tank. It effectively corrodes any mineral buildups in the unit.
  5. The brew funnel needs gentle cleaning once or twice a week. Use warm water and a mild soap too.
  6. Wash the lid of the thermal carafe using non-coarse soap. Again, do it physically and should not dishwasher safe.
  7. Use a toothpick when cleaning off the spray head to remove mineral accumulations within the holes.
  8. Monthly cleaning is needed if you are using hard water for preparing coffee. It has rich mineral content that tends to hoard in your machine. The same applies if you are filling the reservoir with a dipped (unwashed) carafe.
  9. Make it a habit to always empty the water in your Bunn coffee maker. Do this every time you store it or take it somewhere. Turn the unit upturned over a sink while holding it securely. Dispense the contents out of the water reservoir. Just continue holding it upside down until there’s no water flowing from all parts.

How Fast Can You Make Coffee With Bunn?

Approximately three minutes! The secret lies in the Speed Brew Technology and stainless-steel water tank. Just keep the water tank full and always turn the machine on to make cups any time. It is especially ideal for on-the-go coffee buffs. Besides, you can pour 4-10 cups of water in the brewer and have the coffee on your hands instantly.

How Do You Check the Water Temperature?

The right brewing temperature for a Bunn coffee pot is below 91° Celsius or 195° Fahrenheit. To check, put a bare funnel on an unfilled dispenser, then start a brew cycle. Use a thermometer for measuring the water temperature. Make some adjustments if you think the temperature needs to redouble.
