How often do I need to clean my brewer?

Clean your brewer at least every 3 months. Mineral deposits may accumulate due to impurities in the water used to brew. If deposits are not removed, they can impair the operation of the brewer and reduce product life. The frequency of cleaning depends on the mineral content of your water. (The higher the mineral content the more often you should perform brewer cleaning.)

• Improper maintenance or care.

• Deterioration of seals or gaskets within your brewer that naturally occur over time.
• Accumulation of mineral deposits from your water. Clean your brewer regularly.

Why is my machine only brewing a partial pot?

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.
• Adjust coffee and water volume to suit your taste. For a bolder cup, use less water or more coffee.
• If the Sprayhead is missing, the grounds will not be soaked properly. To request a new Sprayhead, complete the Parts form or call 800-352-BUNN (2866).

Velocity Brew®

If you have soft water or drink decaffeinated coffee, you may need a flow restrictor Sprayhead to replace the standard Sprayhead you are using. This will slow down the flow of water, improving coffee extraction. To request a flow restrictor Sprayhead, complete the Parts form or call 1-800-352-BUNN (2866).

Is it safe to leave my coffee brewer plugged in at all times?

What if I don't plan to use the brewer for several days?

Velocity Brew®

If you won't be using your brewer for several days, you can position the Vacation or Tank Switch (on the side) to "off". This will completely shut off the brewer.

Why did my programmed Auto-Start not work?

Phase Brew®

Make sure the AM/PM option was accurately selected. Reprogram for Daylight Savings Time or a power outage if needed. Always make sure Auto-Start button is illuminated.

Can I use a BUNN® brewer if I live in a high altitude location?

Modelos Velocity Brew® and Phase Brew®
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 accommodate the lower boiling temperature that occurs in these locations.

My Café® MC or MCU and trifecta® MB
My Café and trifecta MB can be programmed for high altitude use. Please see manual for programming instructions.

Can I use my Thermal Carafe on a model that came with a Glass Carafe?

Velocity Brew®
Phase Brew®
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.
