frequently if heavily roasted coffees are used. Over extraction may also
cause oiliness, indicating a need to clean your coffee maker.

CLEANING YOUR COFFEE MAKER

CAUTION: Always make sure coffee maker is unplugged before
attempting to clean. To protect against electric shock, do not immerse
cord, plug or unit in water or other liquid.
The outside of your coffee maker can be cleaned by wiping the surface
with a damp, soft cloth.
IMPORTANT: Never immerse the coffee maker in water or other liquid.
Clean inside of carafe with wash cloth and mild soap. Do not use harsh
abrasives or scouring pads on carafe.
Carafe lid and removable filter basket may be washed with warm, soapy
water or placed in the top rack of the dishwasher. Do not place any other
parts of the coffee maker in the dishwasher.
To clean the permanent filter, empty the grounds and rinse thoroughly.
Do not clean the inside of the water reservoir with a cloth as the cloth may
have a lint residue that could clog the coffee maker.
For stubborn stains, use a nylon or plastic pad with a non-abrasive
cleaner. Do not use metal scouring pads or abrasive cleansers.
Calcium deposits may build up in the coffee maker as a result of minerals
commonly found in drinking water. The build-up is normal and may result
in a slow down of the coffee maker's brewing time. The slow down can be
eliminated by periodically decalcifying the coffee maker.
To decalcify, fill the carafe with cold water and two tablespoons of white
vinegar. Pour the solution into the water reservoir, then close the lid.
Place the carafe on the carafe plate and allow the coffee maker to brew
the vinegar solution. While decalcifying, do not use a filter in the filter
basket. When the vinegar solution has finished brewing, empty the carafe
and rinse it out with cold water. Refill the water reservoir with cold water
only and run another brew cycle to remove any remaining vinegar
solution. Repeat if necessary.
