Other Consumer Safety Information

This appliance is intended for household use only.

WARNING Electrical Shock Hazard: This appliance is provided with a polarized plug (one wide blade) to reduce the risk of electric shock. The plug fits only one way into a polarized outlet. Do not defeat the safety purpose of the plug by modifying the plug in any way or by using an adapter. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, have an electrician replace the outlet.

The length of the cord used on this appliance was selected to reduce the hazards of becoming tangled in or tripping over a longer cord. If a longer cord is necessary, an approved extension cord may be used. The electrical rating of the extension cord must be equal to or greater than the rating of the appliance. Care must be taken to arrange the extension cord so that it will not drape over the countertop or tabletop where it can be pulled on by children or accidentally tripped over.

To avoid an electrical circuit overload, do not use another high-wattage appliance on the same circuit with this appliance.

Troubleshooting – Single-Serve Side

Coffee Maker will not brew/coffee not dispensing.

• Piercing Needle may be clogged. Always remove Gray Removable Needle Holder. Clean Piercing Needle in Lid of Coffee Maker as shown on page 9.
• Mineral deposits have formed. Clean Coffee Maker following directions in Care and Cleaning section.
• Too little water. Need 15 oz. (444 ml) or more.

Coffee tastes bad.

• Too much water was added or too much or too little ground coffee was added. Change ratio of water to coffee grounds or use less water with coffee pods.
• Poor coffee quality and freshness.
• Poor water quality. Use filtered or bottled water.
• Soft water causes poor coffee extraction, which leads to poor tasting coffee. Use filtered, spring, or bottled water.

Coffee sediment in cup.

• Try a coarser grind of coffee, or add a #1 paper cone coffee filter to Removable Brew Basket. Make sure hinged Lid is closed on Removable Brew Basket.

Water on counter under unit.

• Overfilled Water Reservoir. Do not add more than 40 oz. (1.2 l) of water. Some mugs/cups do not pour cleanly and can dribble water down side of cup and onto counter.

Bubbles in reservoir indicate high pressure. One of the following occurred.

• Lid opened during brew or after FIL H2O error. Don't open lid during brewing and keep lid closed for 1minute after FIL H2O error.
• Needle clogged. Follow "Clogged Needle" instructions on page 9.
• Grounds basket loaded with too much fine grind coffee. Use a lesser amount of ground coffee. 3 tablespoons (44 ml) is maximum amount of grounds to brew.

Control Panel Notifications:

• CLOSE LID: Coffee Maker Lid is not closed properly. Push Lid down to lock into place.
• NEEDLE: Needle is clogged or grounds basket is overloaded. Do not fill grounds basket above MAX fill line. Always remove Gray Removable Needle Holder and follow “Clogged Needle” instructions on page 9.
• FIL H2O: Not enough water. Add water to Water Reservoir and press [BREW NOW] button to clear Display. Press [BREW NOW] button to restart brew cycle.

Coffee overflows from Brew Basket.

• Use Removable Brew Basket with Lid for ground coffee.
• Use a lesser amount of ground coffee. 3 tablespoons (44 ml) is maximum amount of grounds to brew.
• When using whole bean coffee, a standard automatic drip coffee grind will yield best results. Be careful not to overgrind, since very finely ground coffee can cause overflow.
• Black Seal around Needle in Removable Needle Holder is missing. Carefully place seal around needle and push until in place.
• Do not use soft water. Use filtered, spring, or bottled water.

Coffee overflows from travel mug or regular mug.

• Empty mug after manually stopping brew cycle. Press [BREW NOW] button to start a new brewing cycle.

Coffee single-serve pod bursts.

• There is variability in single-serve pod manufacturing process which causes some types of single-serve pods to be weaker at seams so foil seal fails. Try a different brand.
• If you are using softened water or live in an area where your tap water is naturally soft, this can cause single serve pod issues and filter basket overflows. Use filtered, spring, or bottled water.

Delay Brew feature does not work with Single-Serve side.

• Delay Brew feature is not designed to work with Single-Serve side. Program mode is for Carafe side only.

Troubleshooting – Carafe Side

Longer than normal brew time.

• Bold brewing cycle takes longer to brew to produce a rich, full bodied cup of coffee.
• Mineral deposits can build up in pump of your Coffee Maker. Periodic cleaning of inside of unit is recommended. More frequent cleaning may be necessary, depending on hardness of your water. See "Care and Cleaning" section. NOTE: Do not disassemble unit.

Brew Basket overflows or coffee brews slowly.

• Excessive amounts of ground coffee.
• Decaffeinated and/or coffee ground too finely can cause overflow. Use slightly less grounds when brewing decaffeinated, flavored, or finely ground coffee. Or use medium ground coffee.
• Coffee Maker needs cleaning. See Care and Cleaning on page 9.
• Do not use soft water. Use filtered, spring, or bottled water.

If using a paper filter:

• Coffee grounds between paper filter and Brew Basket.
• Paper filter not open and in proper position.
• Rinse Brew Basket before inserting paper filter so edges will remain pressed against sides of Basket.
• Poor-quality paper filter.

Coffee leaks onto base.

• Carafe removed from Warming Plate for more than 20 seconds during brewing cycle.

Coffee tastes bad.

• Coffee Maker needs cleaning. See Care and Cleaning on page 9.
• Coffee ground too coarsely or too finely. Use medium ground coffee.
• Coffee-to-water ratio unbalanced. Adjust for personal preference.
• Poor coffee quality and freshness.
• Poor water quality. Use filtered or bottled water.
• Soft water causes poor coffee extraction, which leads to poor tasting coffee. Use filtered, spring or bottle water.

Coffee sediment in cup.

• Use a high-quality, basket-style paper filter.

Coffee not brewing or unit will not turn on.

• Carafe not positioned on Warming Plate.
• Water Reservoir is empty.
• Unit is unplugged.
• Power outage.
• Power surge. Unplug; then plug unit back in.
• Clock requires reset after power outage.
