Cleaning a bunn coffeemaker

Replace and run a pot of clean water thru it.

Tank and tank components should be delimed regularly
depending on local water conditions. Excessive mineral build-up
on stainless steel surfaces can initiate corrosive reactions resulting in serious leaks.

Decalcification
Decalcification refers to the removal of calcium
deposits which form over time on the metal
parts of the coffeemaker.
For best performance from your Brew Central
Thermal™ Coffeemaker, decalcify the base unit
from time to time. The frequency depends upon
the hardness of your tap water and how often
you use the coffeemaker. The flashing Clean
light will indicate when you should clean your
coffeemaker.
If the Clean light begins to flash when the
coffeemaker is turned on, it is telling you that
the calcium buildup is interfering with the
functioning of your coffeemaker and the flavor
of your coffee. To clean, fill the water reservoir to
capacity with a mixture of ¹⁄³ white vinegar and
²⁄³ water. Press the Clean button. When the self
clean light glows, turn the coffeemaker on by
pressing the on/off button. The Clean light will
shine steadily. The coffeemaker is now in Clean
mode. One cycle should be sufficient to
adequately clean the coffeemaker. When the
cycle is completed and the five beeps sound,
the coffeemaker will shut off. Turn the
coffeemaker ON to see if the Clean light
continues to flash. If it does, turn it to OFF and
then repeat the cleaning procedure with a fresh
solution of vinegar and water.
If the Clean light no longer flashes, turn the
coffeemaker to OFF and then run one cycle of
fresh cold water through the unit before using
the unit again to brew coffee.
Notes on the Clean F unction
Pressing the Clean button cancels all other
settings. If it is pressed accidentally, press it
again to return the coffeemaker to all its
previous settings. Pressing ON/OFF will also exit
the Clean Mode and turn the coffeemaker OFF.

Yes, the coffee maker keeps a tank of water pre-heated, that is what allows it to brew coffee in a couple of minutes. The exception would be vacation (away from home) or other times when you won't be using it for a few days. Visit www.bunnomatic.com if you have lost your user manual.

With your brewer still turned on and full of water, pour 1 quart of white vinegar into the top and place the decanter on the base and close the lid. Allow the vinegar to stay in there for 2 hours. Then you will need to flush out the machine with 8-10 decanters of water. There is a manual located on the website www.bunn.com. Select @ home then go to products. Select the model and then there is an option to download the manual. Or you can call customer service with the model and code date and a manual can be sent out to you.

you can always clean a coffeemaker with vinegar, but always pour in cold, so you can do it twice or more, but dont re-use the stuff you just used, wait till it's cold or just use some other.after use clean by let water through 2 or 3 times, (also only cold water)

You can download the operating manual for your machine in pdf format right to your computer from www.bunn.com By the way, I wouldn't personally put vinigar in any Bunn machine, as it takes forever to run enough water through them to get rid of the vinigar taste.

According to the manual for IS series Mr. Coffee for programmable models:
1. Prepare one batch of Mr. Coffee coffeemaker cleaner. Pour the mixture into the water reservoir. Remove the water filtration disk from the machine.
4 cups or 20 oz. of undiluted, white household vinegar may be used as a substitute for the cleaner.
2. Place an empty paper filter or permanent filter into the filter basket and close.
3. Place the empty decanter back in the unit, centered on the warmer plate.
4. Press SELECT button until the red CLEAN indicator light is illuminated. For your convenience the cleaning cycle is automatic. The entire cycle will take 45-60 min to complete. During the cleaning your coffeemaker will:

• Slow brew approx. 3 cups of cleaning solution.
• Pause for 30 min (the CLEAN light will remain on to alert you that the process is active). At the end of the pause period your coffeemaker will beep.
• After 30 mins your coffeemaker will brew the remainder of the cleaning solution.
• When complete, the CLEAN light will turn off and your coffeemaker will automatically beep and shut off.

5.Discard the cleaning solution and rinse the decanter thoroughly with clean water.
6. Fill the water reservoir with clean fresh water.
7. Place the empty decanter back on the coffeemaker, centered on the warmer plate.
8. Remove and discard the filter used during the cleaning cycle and replace it with a fresh paper filter. If a permanent filter was used during cleaning, remove it and rinse it thoroughly before replacing it in the filter basket.
9.Begin brewing and allow the full brew cycle to complete.
Repeat steps 6-9 one more time.
