Before plugging in the brewer the first time, please do the following:

Step 1. Raise the hinged flip-lid.

Step 2. Slide an empty brew funnel into the brewer under the warmer switch. Pour one pitcher of water (filled to the 48 oz. line) into the screened area on top of the brewer. Wait two minutes to allow the water to fill the tank. Pour a second pitcher of water into the brewer. When the tank is full, 4 to 6 cups of water will flow through the funnel and into the decanter.

Step 3. Close the lid and plug in the brewer.

Step 4. Press the bottom of the vacation switch, located on the lower left side of the brewer, to the "ON" position. The vacation switch controls power to the tank heater. Initially you will have to wait approximately 15 minutes in order for the water to reach brew temperature.

2. When I pour in a container of water, I don't get a full pot of coffee?

• Water absorbs into the coffee grounds and coffee filter.
• If the brewer has not been used for several days or you have brewed several partial pots of coffee, some water will have evaporated and you will have to replenish the water supply by pouring more water into the brewer.

4. 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 refrigerator in a sealed container.

• 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 click here, or call 800-352-2866.

• 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 click here, or call 800-352-2866.

5. Can I pour cold coffee back into the reservoir to reheat it?

6. Why do I get grounds in my coffee (why does my funnel overflow?)

7. Why does my coffee brewer make loud rumbling noises?

When the water is being heated to the proper temperature, it can make gurgling or boiling sounds. If these sounds are getting louder, there may be a mineral deposit buildup . To prevent this, please see your manual or our cleaning page online to see how to clean your brewer regularly to keep it free from deposits.

8. How do I drain my coffee brewer?

1. Unplug the brewer, place an empty decanter on the warmer plate and pour cold water through to lower the water temperature. Wait 15 minutes for brewer to cool.
2. Remove the glass decanter and filter basket from the coffee brewer.
3. Remove the sprayhead (the round disk above the brew funnel) by turning counterclockwise.
4. Grasp the brewer and carefully turn it upside down over a sink. Most of the water in the tank will flow from the sprayhead opening but some water may flow from the area around the top lid. Continue tipping the brewer until the flow of water ceases.
5. Reinstall the sprayhead when all of the water has drained from the brewer. Securely tighten it by turning clockwise.
6. DO NOT plug in until you repeat brewer start-up procedures from number 1 above.
