BASIC CLEANING
FOR SPEED BREW MODELS: (Excluding Thermal models)
• Wash the brew funnel and glass carafe after each use.
• Both are top rack dishwasher safe.
Important: Separate the carafe lid from the carafe when
washing in the dishwasher, and use the top shelf only for
both the glass and the lid. If washing by hand, use a mild,
non-abrasive dish soap.
• Wipe the outside of the coffee maker occasionally,
including the area above the brew funnel.
NOTE: After wipe down, ensure that the warmer switch
is in the OFF position.
FOR THERMAL MODELS:
Important: Do not use an abrasive device to clean the carafe,
because it will scratch the stainless steel. Occasionally, remove
the brew-through valve on the Thermal Carafe lid and clean
with mild, non abrasive detergent. To remove the valve, lift at
the edge and pull up. Be sure to clean the passage where the
valve is located (valve not on all models).
• To remove coffee stains from inside the thermal carafe,
place a paper lter in the brew funnel and pour 2
teaspoons of powder dishwasher detergent into the
brew funnel.
• Pour one carafe of water into the coffee maker.
• Place the carafe under the funnel and close the lid.
• When the brewing cycle stops, remove the brew funnel
and discard the lter.
• Rinse the funnel.
• Allow the carafe to sit for about 15 minutes.
• Use a soft bristled brush to clean the inside and outer rim
of the carafe.
• Scrub the carafe pour lip and lid with a soft cloth, warm
water and mild detergent.
• When nished, pour out the solution in the carafe.
• Rinse the carafe and the lid.

12
CLEANING THE SPRAYHEAD
Cleaning the sprayhead tube removes deposits formed
by natural mineral content in your water. The more
mineral content in your water, the more you should clean.
A good rule of thumb is to clean it every 3 months.
If you have very hard water, then twice a month may
be necessary.
You will need: a toothpick, dish soap, and a soft cloth.
• Press the tank power switch to the OFF position, unplug
the coffee maker and allow it to cool for at least 2 hours.
• Remove the funnel and unscrew the sprayhead,
loosening with your ngertips.
• Reinsert funnel in machine.
• Pour a carafe of fresh water into the coffee maker.
Keep lid open.
• Place the empty carafe under the funnel and close the
lid. Water will ow into the carafe.
• Check the sprayhead holes and clear any deposits
with the toothpick.
• Clean the sprayhead with a cloth and dish soap.
Rinse with water.
• Empty the water from the carafe and replace the empty
carafe under the funnel.
• Remove the brew funnel and reinstall the sprayhead.
Reinsert the brew funnel.
• Plug in the coffee maker. Press the tank power switch
to the ON position.
• Wait 15 minutes for the water in the tank to reach
brew temperature.
• Your machine is again ready for brewing.
*NOTE:For a replacement sprayhead, call customer service at
1-800-352-2866 (USA) or 1-800-263-2256 (Canada).

13
ROUTINE CLEANING
Routine cleaning of your coffee maker removes mineral
deposits in the internal hot water tank and will prolong the
life of your coffee maker.
You will need: 1 quart (32oz) of white vinegar, a toothpick
and dish soap.
• Slide the brew funnel into the funnel rails.
• Place the carafe under the funnel.
• Open the lid and pour the vinegar into the
coffee maker.
• Close the lid. Empty the carafe when liquid
stops owing.
• Flip the tank switch to the OFF position and unplug the
coffee maker. Allow the vinegar to sit in the
coffee maker for at least 2 hours.
Routinely clean your coffee maker every 3 months.
More frequency may be needed, depending on the
mineral content in your water.
• Remove the brew funnel and unscrew the sprayhead.
Check the sprayhead holes and clear any deposits
with the toothpick.
• Clean the sprayhead with a cloth and dish soap.
• Rinse with water.
• Pour a carafe of fresh water into the coffee maker. Place
the carafe under the funnel and reinsert the funnel.
• Close the lid (the water will begin to ush out the vinegar
from the internal hot water tank).
• Empty the carafe when the liquid stops owing.
• Repeat the process of cycling fresh cold water 3 or more
times, or until you no longer smell vinegar.
• Remove the funnel and reattach the sprayhead.
• Replace the funnel and place the carafe under the funnel.
Plug in the coffee maker. Flip the tank switch to the
ON position.
• Allow the water in the tank to reach brewing temperature
(which should take about 15 minutes). Your coffee maker
is again ready for brewing.

TROUBLESHOOTING
COFFEE IS COLD
• Check if coffee maker is plugged in, and if Tank Power Switch is ON. If the coffee maker
was not ON, wait 15 minutes for tank to reach operating temperature.
• Tank may not have reached operating temperature before brewing. The tank will reach
operating temperture 15 minutes after the coffee maker has been turned ON, or after a
brew cycle.
COFFEE MAKER MAKES
RUMBLING NOISE
• This is normal if it occurs after a brew, or intermittently throughout the day. This occurs
as the water in the tank reheats.
• This sound may indicate that there is lime build-up on the heater. Clean the unit as
directed in the ROUTINE CLEANING section of the manual.
WATER FLOWS BEFORE
LID IS CLOSED
• Make sure lid is completely open to activate the rubber stopper in the pour-in bowl.
• The coffee maker is not deisgned to hold water in the pour-in bowl overnight.
• Remove the top cover to ensure that the rubber stopper is in palce and the area is clean.
FUNNEL OVERFLOWS
• Are you using BUNN lters? Other lters may be the wrong size or porosity. You can
order more BUNN lters at bunn.com.
• Check to see if sprayhead is in place. If sprayhead is missing, the funnel will overow
• If you brew decaf, use ne ground coffee, or have soft water, you may require use of a
special ow restrictor sprayhead. One can be obtained by completing an online form
at www.bunn.com/home-products/parts-form or by calling 1-800-352-2866 (USA) or
1-800-263-2256 (Canada).

16
COFFEE ONLY
PARTIALLY BREWED
• If the coffee maker has been left ON for an extended time without being used, then
the water tank may need to be topped off. Now that the tank has been relled,
brewing should provide the same volume as normal.
NOTE: There will always slightly less volume of brewed coffee than water poured in
the coffee maker due to water absorbed by the coffee grounds.
BREW TIME IS
TOO SLOW
• Sprayhead holes may be clogged. Clean the sprayhead as directed in the CLEANING
THE SPRAYHEAD section of the manual.
• The tank and spayhead tube may have lime build-up. Clean the unit as directed in the
ROUTINE CLEANING section of the manual.
• If the previous solutions do not work, you may need a deliming tool to remove
excess lime build-up. One can be obtained by completing an online form at
www.bunn.com/home-products/parts-form or by calling 1-800-352-2866 (USA) or
1-800-263-2256 (Canada).

COME OUT
• Were at least 20oz of water poured into the coffee maker? Between 20oz and 50oz of
water must be poured in for proper brewing. (See HOW TO BREW section of manual).

until the lid is closed.
• If coffee maker has been left ON for an extended period without being used, the
water level in the tank may need to be topped off. Press power switch OFF, unplug the
coffee maker, and go through the setup process until water begins to ow as directed
in the INITIAL SETUP section of the manual.
• Has the coffee maker been in storgage. Go through the initial setup as directed in the
INITIAL SETUP section of the manual.
• If there is still water in the pour-in bowl, the sprayhead may be clogged. Clean the
sprayhead as directed in the CLEANING THE SPRAYHEAD section of the manual.
• If the previous solutions do not work, you may need a deliming tool to remove
excess lime build-up. One can be obtained by completing an online form at
