CLEANING INSTRUCTIONS

Daily washing and cleaning of the brew funnel and decanter after each use is required.

Occasionally, wipe the outside of the brewer, including the area above the funnel, with 

mild, no citrus added dish soap and a damp cloth. The brew funnel and decanter are top 

rack dishwasher safe. Please see page 9 for instructions on cleaning your thermal carafe.

DELIMING

You should delime your BUNN brewer to clear any deposits that may have accumulated 

due to impurities in the water source. The frequency of deliming depends on the mineral 

content of your water.

NOTE 

- Unplug the brewer and let it cool down before deliming.

1.   Remove the sprayhead by turning with your fingertips and set it aside.

2.   Insert all but 5.1 cm (2 inches) of the flexible deliming tool (supplied) into the 

sprayhead tube. Call 800-263-2256 or visit www.bunn.com for a replacement 

deliming tool.

3.   Slide the tool in and out five or six times to loosen lime in the sprayhead tube. You 

may need to twist, push and use some force when inserting the tool, then remove.

4.   Prior to replacing sprayhead, pour one decanter of fresh water into the brewer. 

Position empty decanter on the brewer and close the lid. Water will flow into decanter.

5.   Check the holes of the sprayhead. If plugged with mineral deposits or white flakes, 

they may be cleared by using a toothpick. Clean the sprayhead with a cloth and mild 

detergent. Rinse the sprayhead with water, then reinstall. Empty water from decanter.

6.   Plug in the brewer and allow the water in the tank to reheat before using 

(approximately 15 minutes). 

PERIODIC CLEANING

You should clean your BUNN brewer at least every 3 months. The frequency of cleaning 

depends on the mineral content of your water.

1.   Slide an empty brew funnel into the brewer under the sprayhead and center an empty 

decanter on the base plate.

2.   Open the lid and pour one quart of white vinegar into the top of the brewer; close the 

lid. Empty the decanter when liquid stops flowing from the funnel.

3.   Allow the brewer to sit plugged in for two hours.

4.   Unplug the brewer. Remove the brew funnel and sprayhead from the brewer. Clean 

the sprayhead with a cloth and mild detergent.

5.   To drain the brewer, continue to Step 6, 

OR

 to clear vinegar out of brewer without 

draining, pour a decanter of fresh, cold water through the brewer. With funnel in 

place, position decanter on base plate, then close the lid to allow the water to run 

through the brewer. After it has run through, empty decanter and repeat the process 

approximately 8 - 10 times.

 

Proceed to Step 9.
