The most common problems normally associated with Cuisinart coffee makers are weird tasting coffee, loss of power to the unit, and brewing too much or too little coffee, according to reviews on JavaJenuis.com and Matthew-Epstein.com. Most problems can be avoided with proper care and cleaning of the coffee maker.
Weird tasting coffee is typically the result of calcium buildup inside the coffee maker. A vinegar and water blend can help clean out calcium and return the unit back to normal. Some models have been reported to overflow, but this problem is typically the result of using a finely ground coffee with a slower drip rate. Losing power to a unit is normally caused by a faulty wire or outlet.
