  3. To protect against electric shock, do not place or immerse cords, plugs, or appliances in water or other liquid.
  4. This appliance is not intended for use by children or by persons with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge. Close supervision is necessary when any appliance is used near children. Children should be supervised to ensure that they do not play with the appliance. Keep the appliance and its cord out of reach of children.
  5. Unplug from the outlet when either the appliance or display clock (if provided) is not in use, and before cleaning. Allow to cool before putting on or taking off parts, and before cleaning the appliance.
  6. Do not operate any appliance with a damaged cord or plug or after the appliance malfunctions, or has been damaged in any manner. Return the appliance to an Authorized Service Center for examination, repair, or adjustment. Do not attempt to replace or splice a damaged cord.
  7. The use of an accessory not recommended by the appliance manufacturer for use with this appliance may result in fire, electric shock, or injury to persons.
  8. Do not use outdoors.
  9. Do not let the cord hang over the edge of the table or counter, or touch hot surfaces.
  10. Do not place on or near a hot gas or electric burner, or in a heated oven.
  11. Always attach the plug to the appliance first, then plug the cord into the wall outlet (for appliances with detachable cords). To disconnect, turn any control to the off position, then remove the plug from the wall outlet.
  12. Do not use the appliance for other than intended use.
  13. All lids should be closed during use.
  14. Scalding may occur if the lid is removed or the brew basket door is opened during or immediately after the brewing cycles. Contents may be hot. Allow to cool before opening the lid
    For appliances with sealed capsules:

This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit into a polarized outlet only one way. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to modify the plug in any way. If the plug fits loosely into the AC outlet or if the AC outlet feels warm do not use that outlet.


A short power supply cord (or detachable power supply cord) may be provided to reduce risks resulting from becoming entangled in or tripping over a longer cord. Longer detachable power-supply cords or extension cords are available and may be used if care is exercised in their use. If a long detachable power-supply cord or extension cord is used:

  • The marked electrical rating of the detachable power supply cord or extension cord should be at least as great as the electrical rating of the appliance;
  • If the appliance is of the grounded type, the extension cord should be a grounding type 3-wire cord; and
  • The longer cord should be arranged so that it will not drape over the countertop or table where it can be pulled on by children or tripped over unintentionally.


  1. Place the appliance on a hard, flat, level surface to avoid interruption of airflow underneath the coffeemaker.
  2. Glass decanters only: Discard the decanter immediately if it is ever boiled dry.
  3. Glass decanters only: Protect the decanter from sharp blows, scratches, or rough handling.
  4. Do not operate the appliance with an empty water tank.
  5. Keep the area above the appliance clear during use, as hot steam will escape the appliance.

Clean the Coffeemaker Before Use

Setting the Clock

Water Filtration System
Using the Mr. Coffee® carbon-based water filter in the Mr. Coffee® coffeemaker during the brewing process helps remove up to 97% of the chlorine from the water and improves the taste of your coffee. To use the water filtration system in your MR. COFFEE® Coffeemaker, please follow these steps:

  1. Align the red indicator on the frame to the letter that corresponds with the month that you are using the disk for the first time. This serves to remind you to change the disk every month (approx. 30 brewing cycles). To change the disk, remove the used disk, and insert a new disk into the frame.
    For optimum results, use the water filtration system with a permanent filter.
  2. Rinse the water filter in freshwater before use.
  3. Follow the Adding Water and Coffee Instructions.
  4. Position the filter on top of the brew basket, and brew according to your particular model’s brewing instructions.
  5. When you are done brewing your coffee, rinse the water filter with fresh water. Do not put your water filter in the dishwasher.

Suggested Coffee Measurement Chart:
For best results, brew 4 or more cups of coffee.

Paper Filters vs. Reusable Filters
PAPER FILTERS: To achieve a smoother, less bitter cup of coffee, use a paper filter. It will be most effective in trapping bitter sediments. REUSABLE FILTERS: For a more robust and full taste, use a reusable filter. It will allow the coffee’s full flavor to fill your cup. Reusable filters have tiny holes that allow rich coffee oils to brew through.

While it may not seem like an important ingredient, coffee is 98 percent water. The type of water that you brew with greatly affects the final taste. Always use clean, fresh water that is filtered and free of impurities – avoid soft water or well water. Please refer to the “Water Filtration” section to learn more about how your coffeemaker reduces impurities in water.

A clean coffeemaker is essential to brewing great tasting coffee every time. Cleanliness.


Daily Cleaning

  • CAUTION: Make sure your coffeemaker is unplugged and has cooled completely before cleaning.
  • Remove the brew basket, filter, carafe, carafe lid, and wash them in a solution of hot water and mild liquid soap, and dry thoroughly. You can also place it in the dishwasher; top-rack only.

  1. IMPORTANT: Remove the water filtration system from the coffeemaker.
  2. Prepare 4 cups or 20 fl. oz. / 592ml of undiluted, white household vinegar. Pour the vinegar into the water reservoir.

  4. Place the empty carafe back in the unit, centered on the warming plate.
  5. Brew prepared cleaning solution through the coffeemaker.
  6. Discard the cleaning solution and rinse the carafe thoroughly with clean water.
  7. Fill the water reservoir with 12 cups of clean, fresh water.
  8. Place the empty carafe back on the coffeemaker, centered on the warming plate.
  9. Remove and discard the paper filter used during the cleaning cycle. If an MR. COFFEE® reusable filter was used during cleaning, remove it and rinse it thoroughly before replacing it in the brew basket.
  10. Press Brew Now and allow the full brew cycle to complete, rinsing the coffeemaker with hot water.
  11. Discard the water and rinse the carafe thoroughly with clean water.
