I turned the warming plate off by pressing STAY WARM, but the HOT SURFACE light is still on.
On the glass carafe version, the HOT SURFACE indicator is a safety feature that illuminates when the warming plate is hot. The HOT SURFACE indicator will remain on until the warming plate has cooled to a safe temperature. Do not touch the surface when this light is illuminated.

If my unit comes with a permanent coffee filter, do I need to also use a paper filter?
No, a paper filter and the permanent filter should NOT be used together when brewing coffee. Using both the permanent filter and a paper filter may result in clogging or water and/or coffee backing up in the brew basket.

What grind size of coffee and what size paper filter should I use?
A medium grind coffee is recommended. The brew basket is designed to fit a #4 cone paper filter.

Note: Some models come with a permanent filter and should not be used with a paper filter.

Why did the brewing cycle produce less coffee than expected?
Each size and brew type produces a different amount of coffee to optimize strength and taste. For example, Rich brew will yield less coffee than Classic brew, while Over Ice produces a concentrated amount of coffee that drips over ice to create an iced coffee that's never watered down. Specialty brew will always produce 4 oz. of coffee, while Cafe Forte delivers 8 oz.

Why does the brew basket drip after the brew cycle is complete?
Once the brew cycle is complete, move the drip stop to the closed position (denoted by the image of a water droplet with a slash through it) before removing your brewing vessel to avoid drips.

Why is my Over Ice brew not brewed cold?
Ensure your cup, travel mug, or carafe is filled all the way to the top with ice cubes before brewing. The unit will brew at elevated temperatures to lock in the best flavor, then the ice will cool the brewed coffee or tea to the perfect temperature.

Why is there no warming plate on the thermal carafe model?
The thermal carafe has double-walled insulation, which keeps heat locked inside. The insulation barrier means the heat from the warming plate will not reach the inside of the carafe or affect the temperature of the coffee.

Why is there water left in the reservoir after a brew?
The water reservoir markings are minimum fill lines that indicate the amount of water needed for that brew size. However, all brew styles use different amounts of water to create the proper flavor and concentration, so occasionally some water may remain in the reservoir.
