Frequently Asked Questions - CO108-NK Cosori

What are the preset temperature settings on the Cosori CO108-NK kettle?

The kettle has five preset temperatures: 170°F (for white tea), 180°F (for green tea), 195°F (for oolong tea), 205°F (for coffee), and 212°F (for boiling water, ideal for black tea).

How do I use the Hold Temperature feature?

Press the HOLD TEMP button anytime before the kettle finishes heating. It will maintain the selected temperature for up to 60 minutes after heating completes. The button will stay lit during this time.

What happens if the kettle runs out of water?

The kettle has boil-dry protection. If water level is below ½ cup (118 mL), the heat will automatically shut off. All buttons may blink and the kettle will beep. Unplug the kettle to reset it before refilling and using again.

How do I clean and descale the kettle?

Unplug and let cool. Wipe exterior with a damp cloth. For descaling, boil a mixture of water and lemon juice or white vinegar. Use a non-scratch sponge to remove scale. Rinse thoroughly. Descaling weekly is recommended with frequent use.

Can I adjust the tightness of the lid?

Yes, you can adjust the lid tightness by bending the three tabs on the lid. Push them inward for a looser fit or outward for a tighter fit. Test the fit after adjustment.

How do I turn off the kettle's beeping sounds?

Press and hold the HOLD TEMP button for 8 seconds to toggle sounds on/off. The kettle will beep once when plugged in and three times when water reaches the set temperature.

What is the maximum water capacity?

The maximum capacity is 0.85 quarts (0.8 liters), indicated by the MAX line inside the kettle. Do not fill above this line to avoid boiling over.

Can I use the kettle for pour-over coffee?

Yes, the gooseneck spout is designed for precise pouring, ideal for pour-over coffee. Use the 205°F preset for coffee. Pour in a slow spiral motion to saturate coffee grounds and allow blooming.

Is the kettle safe to use at high altitudes?

Yes. At altitudes above 3,881 ft, use the 205°F preset for boiling; above 9,256 ft, use the 195°F preset. Water boils at lower temperatures at high altitudes.

What should I do if the kettle does not turn on?

Ensure the kettle is properly placed on the power base and plugged into a grounded outlet. If it still won't turn on, check for boil-dry protection activation (unplug to reset) or contact Cosori customer support.

General Safety

CAUTION!

• Do not touch hot surfaces. Use handle. Do not touch the heated parts of the base or the metal walls of the kettle during or immediately after operation.
• Do not fill the kettle above the "MAX" line. This may cause water to boil over and may cause scalding.

• To avoid scalding, always handle with care when there is hot water inside the kettle.

• Do not immerse the kettle, base, cord, or plug in water or other liquids.

• Closely supervise children near the kettle. Do not allow children to use or play with this kettle.
• Unplug the kettle when it is not being used and before cleaning.
• Allow to cool before putting on or taking off parts, and before cleaning.

• Do not use the kettle if it is malfunctioning, or if any part, including the base, cord, or plug, is damaged in any way. Do not try to repair the kettle. Contact Customer Support (see page 14).

• Using accessory attachments not recommended by the manufacturer may result in fire, electric shock, or injury.

• Do not use outdoors.
• Place the kettle on a dry, flat, stable surface.
• Do not place the kettle (including the base) on or near heat sources such as stovetops, ovens, radiators, etc.
• To avoid scalding, always make sure the lid is securely closed while the kettle is operating. Do not cover the spout opening while the kettle is in use. Do not cover the openings on the lid.
• To disconnect, use the On/Off Switch to turn the kettle off, then remove the plug from the wall outlet.
• Only use the kettle as directed in this manual.
  • Household use only.

SAVE THESE INSTRUCTIONS

• Do not let the cord (or any extension cord) hang over the edge of a table or counter. Do not allow the cord to touch hot surfaces.
• This kettle has a 3-prong grounding plug. Always plug in to a grounded electrical outlet. Do not modify the plug in any way.

• This kettle uses a short power-supply cord to reduce the risk of entangling or tripping. Use extension cords with care.

• Any extension cord must also be a grounding-type 3-wire cord.

• The marked electrical rating of an extension cord should be at least as high as the rating of the kettle (see page 3).

Note: If the electrical circuit is overloaded with other appliances, your kettle may not operate properly. Operate it on a separate electrical circuit.

1. Remove all packaging from your kettle and its accessories.

2. Completely unravel the power cable and place the power base on a flat, level, stable surface.

3. Fill the kettle with water to the "MAX" line [Figure 1.0], then put the lid on the kettle. Press firmly to make sure the lid fits securely.

4. Press ("ON / OFF"). Then, press 212°F ("BOIL BLACK").

5. The kettle will automatically turn off once it has finished boiling the water. Allow it to cool, then pour out the water. Rinse thoroughly 2–3 times with cold water.

Figure 1.0

Boiling Water

Note:

• Use filtered water for perfect pour over brewing.

• If you start the kettle without water in it, the kettle will turn off and controls will be disabled. See Boil-Dry Protection (page 11).

• Add at least 12 cup / 118 mL of filtered water to the kettle. Do not fill above the "MAX" line. Wipe any water from the outside of the kettle and the base.

• Put the lid on the kettle and make sure it fits securely. Place the kettle on the power base.
• Plug in the cord. The button lights will blink, and the base will beep once.
• Press "ON/OFF"). The button will light up.

Note: The kettle will turn off after 1 minute of inactivity.

1. Press to choose a preset temperature setting. The button will light up, and the kettle will start heating up the water.

Note:

• You can only select 1 preset at a time.

• If you take the kettle off the base while heating, all buttons will turn off, and the kettle will pause heating. If you put the kettle back within 60 seconds, it will resume heating. After 60 seconds, the kettle will turn off.

• Optionally, press

("HOLD

TEMP") any time before the kettle is finished heating. This will turn on Hold Temperature mode, which will automatically keep the kettle at the same temperature for 60 minutes after heating is finished. The button will stay lit during that time.

Note: If you take the kettle off the base during Hold Temperature mode, the ("HOLD TEMP") button will blink. After 60 seconds, the kettle will turn off.

1. When the water is at the preset temperature, the kettle will beep 3 times and stop heating.

Making Pour-Over Coffee

You'll need a pour-over coffee maker, such as Cosori's Original 8-Cup Pour-Over Coffee Maker.

1. Place the coffee maker filter into the decanter.
2. Add ground coffee to the filter according to your preference.
3. Heat water using the gooseneck kettle.
4. Use the gooseneck kettle to gently pour water over the coffee grounds using a slow spiral motion. Pour just enough water to saturate the grounds.

Note:

• This spiral motion is to create "turbulence" in the coffee grounds, allowing the particles in the coffee to separate and release flavor.

• The water will cause the grounds to puff up, which is called "blooming". Some roasts will bloom more than others.

• Wait 30–45 seconds.

• Use the gooseneck kettle to pour water over the coffee grounds again using a slow spiral motion. If water reaches the top of the filter, stop and let it settle to the halfway point, then begin pouring again until you have the desired amount of coffee.
• When finished, remove the filter and enjoy!

High Altitude Users

At higher elevations, water boils at a lower temperature. You may need to use a different preset.

Altitude Preset for Boiling Water
3,881–9,255 ft / 1,183–2,820 m	205°F COFFEE
9,256 ft / 2,821 m and above	195°F OOLONG

Kettle Sounds

The kettle will alert you by beeping 3 times when the water reaches the preset temperature. The kettle will also beep once when plugged in. To turn kettle sounds off, press and hold 🔊 ("HOLD TEMP") for 8 seconds.

Adjusting Lid Tightness

If you feel the kettle lid fits too loosely or is too hard to take off, you can adjust the tightness of the lid.

1. Take off the lid.
2. Use a tool to adjust the 3 tabs on the kettle lid. [Figure 2.1-2.2]
3. If you push the tabs in, the lid will fit more loosely, and will be easier to put on and take off.
4. If you push the tabs out, the lid will fit more tightly, and will not come off as easily.
5. After adjusting the tabs, put the lid back on and take it off again to see if the fit is correct. If not, adjust the tabs again until the lid fits the way you prefer.

Boil-Dry Protection

Your kettle is equipped with boil-dry protection. If there is less than 12 cup / 118 mL of water in the kettle, the heat will automatically shut off. Allow the kettle to cool and add more water before using again.

If all buttons blink and the kettle beeps, then unplug the power cord to reset the kettle before turning on again.

Note: Do not remove the filter from the lid. Doing so will break the filter.

Cleaning

1. Unplug the kettle and allow it to cool before cleaning.
2. Wipe the kettle and base with a soft, damp cloth. Make sure that the electric socket on the underside of the kettle is kept dry.
3. Dry all parts after every use.

Note: Never immerse kettle or power base in water.

Descaling the Kettle

You should descale the kettle at least once a week if you use it frequently. Descaling removes any mineral deposits that have built up inside the kettle. Always descale the kettle before and after storing for long periods of time.

1. Unplug the kettle and pour out all water. Make sure the kettle is cool.
2. Squeeze half a lemon into the kettle, or add 12 US cup / 118 mL of distilled vinegar into the kettle.
3. If the kettle has thick scale buildup, scrub the kettle's inner walls with a non-scratch scrub sponge.

Note: Do not use steel wool, as this can scratch the kettle.

1. Add 2 US cups / 473 mL of water. Boil the mixture.

2. Pour out the mixture, then wipe off any remaining scale with a non-abrasive cloth, sponge, or cleaning brush.

3. Repeat as needed.

Note: For quick descaling, add 3 US tbsp / 44 mL of baking soda to 12 US cup / 118 mL of vinegar into the kettle. Swirl the mixture around until it coats the walls of the kettle, wipe with a non-scratch sponge, and pour the mixture out. This method will only work for a thin layer of scale.
