Here’s How To Use A Bunn Coffee Maker!

Bunn coffee makers are known for their durability and affordability, but how do you use one properly? With all the different types of Bunn coffee makers, it’s easy to get confused about how to use them. That’s why we’ve compiled the following step-by-step guide on how to use a Bunn coffee maker! Let’s get started!

About The Bunn Brand

Since its founding decades ago, the BUNN-O-Matic Corporation (often referred to as “BUNN”) has become one of the world’s leading manufacturers. The company produces a variety of coffee makers, including single-cup coffee makers and vacuum brewers.  

With headquarters in Springfield, Illinois, and a manufacturing facility in Creston, Iowa, Bunn-O-Matic Corporation is a leading U.S. producer of dispensed beverage equipment, such as coffee and tea. 

They are also an internationally recognized manufacturer of brewing equipment. Known for their patented piston-style brew process, Bunn models have established themselves as some of the most reliable and efficient coffee machines on the market today. 

The original Bunn coffee maker’s design was created by Gordon Bunn Jr., son of inventor Francis Anthony F.A. Bunn Sr., who first introduced it at the 1962 World Fair in Seattle. Today, several variations exist based on size and features, from home appliances to commercial use models like those found at Mcdonald’s or Starbucks.

What Are The Parts Of The Bunn Coffee Maker?

We are here to help if you have never used a coffee maker before and are curious about Bunn’s controls. Let’s begin by reviewing the machine’s components.

The machine features an on/off switch on the left side of the brew funnel, where you will put your ground coffee. When switched on, this button will illuminate in red when it is time to brew another coffee or when it has finished the brewing process. 

Next is a warmer plate where your brewed coffee can stay warm until someone needs more. It also has an indicator light that changes colors based on its setting – red means heating, while green means ready. Finally, there is a removable water reservoir with an indicator window, so you know how much water to add for different brew sizes (1-4 cups). Always fill it up, so you don’t run out of coffee halfway through a pot.

This brings us to the brew basket, which is usually placed over the cup holder and filled with ground coffee before starting a new pot. 

There are two options: paper filters and permanent filters. If using paper filters, place them inside the round-rimmed filter below the brew basket; if using permanent filters, as we recommend, insert them into the metal filter base in front of the brew basket. 

How To Use A Bunn Coffee Maker

Before connecting to your Bunn coffee machine, there are a few things you need to know about its operation. 

How To Empty A Bunn Coffee Maker

The Bunn coffee maker design is such that the coffee filter holder and coffee sit on a heating element. The thermal carafe is placed on top of the coffee filter holder. 

When you turn the Bunn coffee maker on, the heating element heats up, and the water in the coffee filter holder is forced up through the coffee and into the thermal carafe. The entire process takes about 3 minutes. 

To empty a Bunn coffee maker, remove the thermal carafe and pour the coffee. Be careful, as the carafe will be hot. Next, remove any remaining coffee from the filter holder. Next, rinse the filter holder with clean water and put it back in place. 

Finally, pour out any excess water from the pot. Now that your Bunn coffee maker is ready to go again, put the pot back on top of the machine and close up everything else!

Wipe down any outside surface with warm water and mild soap regularly, and thoroughly clean the Bunn Coffee Maker at least once a week. 

Then, before reusing it, properly rinse it to remove all soap residue. You should also wash out any removable parts, like the mesh filter and brew basket. 

Make sure they are free of particles or residue before reinserting them into the coffee maker. Although this process might seem daunting, cleaning your Bunn coffee maker is not as difficult as you think!
