Questions Answers
Where can I find the model and date code on my BUNN brewer?

Find your date code

The model number is located on the sides of the carton in which the coffee brewer was sold, and the six-digit date code is stamped on a small white or silver sticker on top of the carton (if there is a seventh digit on the carton date code, ignore it and use the first six digits). You may have noted the model number and date code in your Use & Care Manual when you set up your coffee brewer.

The model number and date code can also be found on the prongs of the plug, bottom, or back of unit  The trifecta MB serial number is located on the back of the unit.

Why is my coffee dripping out very slowly?
  • The sprayhead may be clogged. Check the round disk (sprayhead) above the brew funnel. The holes in this part must always remain open. If they are clogged, remove the sprayhead and clear the holes using a toothpick. Always unplug the brewer before deliming or cleaning the sprayhead.
  • The brewer could be clogged with mineral deposits. See the Deliming Instructions in the Manual.  NOTE: The frequency of deliming depends on the mineral content of your water.
Why does my coffee taste weak or bitter?

The taste of your coffee can be caused by all or any combination of the following:

  • Variation in the mineral or chemical content of the water (For example, high sulfur content water will carry a strong taste).
  • Variation in brands, mixes, quantity, or quality of coffee.
  • Old or improperly stored coffee can easily taste stale. Coffee should be stored in a clean, dry place away from heat registers and vents or extreme cold for maximum freshness.
  • Size of the coffee grind affects the ability of the brewer to extract the oils that add flavor to your coffee.
  • Missing sprayhead. If the sprayhead is missing the grounds will not be soaked properly. To request a new sprayhead, complete the Parts and Services (click here) form or call 800-352-BUNN (2866).
  • If you have soft water or drink decaffeinated coffee, you may need a flow restrictor to replace the sprayhead you are currently using. This will slow down the flow of water, giving you a stronger flavor of coffee. To request a flow restrictor, complete the Parts and Services (click here) form or call 800-352-BUNN (2866).
What might cause my coffee brewer to leak?

Leaking can be the result of one or more of the following causes:

  • Improper maintenance or care.
  • Normal wear and tear.
  • Deterioration of seals or gaskets within your brewer that naturally occur over time.
  • Accumulation of mineral deposits from your water. Clean your brewer regularly.

  • Please be prepared with the model name of your coffeemaker and the date code located on the metal prongs of the plug, bottom, or back of your unit.
Can I use a BUNN brewer if I live in a high altitude location?
  • Yes. BUNN makes models specifically designed for altitudes of 4,000 ft. and above. The "D" in the model name indicates that it is for high altitude applications. These models have been preset to accomodate the lower boiling temperature that occurs in these locations.
Can I use my thermal carafe on a model that came with a glass carafe?
  • No, our glass carafe brewers have warmer plates that can get very hot. This heat can make the surface of the stainless steel carafe very hot and possibly damage the vacuum insulation.
How do I preheat a thermal carafe?
  • To preheat the thermal carafe, fill the carafe with hot water for approximately 30 seconds. Empty before brewing coffee into carafe.
  • Preheating will increase the time your coffee will stay warm.
