If you want your Bunn pour-over coffee maker to have a long life, you should regularly descale it to remove the lime deposits that gather in your machine. The importance of this is even greater if your water is hard, as scale deposits can build up quickly. An excessive build-up of layers in the tank of a brewer will typically induce it to spit and steam. Descale your brewer to sustain its production regularly.
Cleanse The Water Line
Connect the water line to the machine if the machine is automatic and keep it plugged in. Deliming your water about every three months is recommended if you have hard water. Your brewer will need less limescale inhibition when you use a water filter system.
Slide the empty brew funnel into the machine and place an empty glass carafe or Airpot under it.
Use A Standard Descaler
Pour In The Vinegar
Pour four cups of vinegar on top. Place the carafe underneath the coffee machine.
Clear The Carafe
Plugin the power plug and turn off the machine (it can be off while brewing). Unplug the appliance when you are finished.
The Bunn coffee maker requires you to pour vinegar into it. Your water tank pushes out of the water after vinegar falls into it. Just rinse the water with this.
Vinegar will work its magic
The vinegar will do its magic once it’s in the water tank. As a result, please allow two hours.
Eliminate The Nozzle
Next, two hours after installing the Bunn coffee machine, you will remove the nozzle. Print heads are very hot, so it is not wise to do this earlier.
If there are mineral deposits in the nozzle, you can examine them now. Toothpicks are the solution to that problem. Check it out if you wish. Rinse with soap and wash.
Fresh Water Inside
Fill the Bunn coffee machine with clean water now. Pour water into a carafe and use it for this. But make sure you have the brewing funnel ready.
Wait until the rinse is complete before placing the carafe.
A hot water tank will produce a lot of vinegar. Usually, this process needs to repeat four or five times, or until the vinegar smell no longer happens soon, and you may even see the coffee machine’s interior stacked with solid pieces. Now, you can empty and discard it. To stop smelling the vinegar, you’ll need to repeat the steps 4 to 5 times.
A New Nozzle Is Needed
We must replace this nozzle now. Put back the sprinkler and remove the brewing funnel.
Connect the Bunn coffee maker to the brewing funnel and open the Bunn coffee maker when it’s finished. You must follow this procedure. It will take about 15 minutes for the water to heat up.
On top of the vinegar, you will pour four cups. Under the coffee maker, make sure you place the carafe.
Cleanse The Spray head
If any built-up lime has accumulated inside the spray head tube, insert your deliming spring as deep as it will go and work it back and forth a few times to dislodge it. If a mineral deposit or white flakes appear around the spray head holes, clean them with a toothpick.
Run Brew Cycle
Pour cold water into the Airpot then, cover it (if you have an automatic brewer, set it to brew). Vinegar will then begin to flush from within the water tank as the water is flushed. Underneath the carafe / Airpot, place the vinegar solution and water. Make sure you repeat this ten times before you get rid of the vinegar smell.
An Alternative Used Extensively
A second way to remove vinegar and water from a brewer is to turn it upside down over a sink (disconnect the water line if the brewer is automatic first) and run it over the sink until the vinegar and water solution drains. Make sure the water stops coming out of the sink after 30 minutes.
Fill the top of the machine with cold water until water starts escaping the spray head tube. Turn it right side up and spray. At least three times, turn the container upside down and refill until the vinegar smell has disappeared.
Re-Install The Spray head
Install the spray head by turning it counter clockwise. Reconnect the brew funnel and plug in the machine once the tank is full of water. The water in the tank will need about a half-hour to warm back up to brewing temperatures.
The Final Verdict
When the tank heater and probes become caked with lime, they may not function properly. Remove lime deposits. Clean and inspect them for damage. If you still have stubborn deposits in your machine, run a de-liming cycle as well.
Deposits of lime in the tank heater may cause noise and vibration while it is operating. When lime deposits occur, clean and remove. In case you have stubborn deposits in your machine, run a de-liming cycle as well.
