How long does it take to make coffee?

It takes approximately 1 minute per cup to brew coffee.

What is the size of a cup of coffee?

The standard used in the coffeemaker industry for a “cup” of coffee is 5 fluid ounces. To ensure a 5 ounce cup of brewed coffee, the cup markings on the coffeemaker represent 5 ½ ounces per cup as some water is absorbed by the coffee grounds and some is lost in steam during the brewing cycle.

What type of coffee should I use?

Use a regular grind coffee. If you grind your own coffee beans, grind to a medium coarseness for best results. DO NOT grind too fine, as this can cause the basket to flood.

How much coffee should I use?

As a guideline, use the following amounts of ground coffee for the number of cups being prepared. Use standard measuring cups to measure the coffee. The amounts of coffee below will brew mild to medium strength coffee. The amount of coffee can be adjusted to suit personal preference. As a guide, there are about 5 cups of coffee to a pound.

  • 12-18 Cups Coffee= 1 – 1 ¼ Cups Grounds
  • 20-25 Cups Coffee= 1 ¼ - 1 ½ Cups Grounds
  • 28-36 Cups Coffee= 1 ½ - 2 Cups Grounds
  • 40-45 Cups Coffee= 2 – 2 ½ Cups Grounds
  • 50-60 Cups Coffee= 3 – 4 Cups Grounds
  • 70-80 Cups Coffee= 4 ½ - 5 Cups Grounds
  • 90-100 Cups Coffee= 5 ½ - 6 ¼ Cups Grounds

Do I need to use a filter?

Paper filters are not necessary in the large capacity coffeemakers. Before adding coffee grounds to the basket, wet the basket to minimize coffee grounds falling into the coffeemaker.

What are the amps, watts and volts of my coffeemaker?

The wattage and voltage can be found on the bottom of the coffeemaker, distinguished with a W or V. Amps can be calculated by dividing the watts by volts.

Can I heat other liquids in the coffeemaker?

We do not recommend any liquids other than coffee or water be heated in the coffeemaker to prevent damage to the heating element.

Do I have to use the stem and basket in the coffeemaker when heating water?

We recommend that the stem and empty basket be used when heating water to ensure even heating of the water.

What temperature do coffeemakers reach?

Large capacity coffeemakers will reach between 182-196°F at the end of the brew cycle and will keep the coffee hot for serving in about the same temperature range.
If your coffee is not hot enough, be sure the heating well is clean.

When heating water, the inside of the coffeemaker discolors. How can I clean this and why does it happen?

The interior will discolor due to minerals present in the water. This is normal and does not affect the coffeemaker or the water heated. To lighten the discoloration, fill the coffeemaker with water to the level of discoloration (at least to minimum cup level, but not past the maximum cup level). With the stem and empty basket in place, add 2 teaspoons cream of tartar to the basket for every 12-15 cups of water in the coffeemaker. Secure the cover, plug in and turn on if model has a switch. When brewing cycle is completed, unplug the appliance, allow it to cool and discard contents. Wash and rinse coffee basket, stem, and inside of coffeemaker thoroughly.

How do I remove mineral deposits?

Fill the coffeemaker with 1 quart EACH of water and white distilled vinegar. If a white mineral buildup has formed on the inside of the coffeemaker, use an additional 2 cups of vinegar. Insert the stem and empty basket and put the cover onto the coffeemaker, plug in and turn on. Allow the coffeemaker to complete the perking cycle, then let stand for 20 minutes.
Unplug the cord from the outlet. Drain the coffeemaker and allow it to cool. Wash and rinse coffee basket, stem and inside of coffeemaker thoroughly. To clean the heating well use a scouring pad around the narrow end of the cleaning tool, insert into the heating well, and twist until clean. If you don’t have the cleaning tool, use a scouring pad to scrub the heating well.
If the heating well is not clean, the thermostat will not sense correctly and the coffee will not be as hot as it should be.

Is my coffeemaker NSF approved?

Ratings and certifications can be found stamped on the bottom of the coffeemaker, on our product Web pages, and the product cartons.
