A: All Zojirushi coffee makers are tested to function at an altitude of up to 5,000 feet above sea level. At higher altitudes water evaporates faster which may cause the coffee makers not to function properly.
A: Replacement parts may be ordered from our online Zojirushi Parts & Accessories page or by calling our Customer Service Department at 800-733-6270, M-F, 8:00 a.m. to 5:00 p.m. PST. Please have the model number ready when calling.
A: Depending on the type of coffee or brand and/or color of the Basket Coffee Filter being used, coffee grounds may overflow from the Basket Coffee Filter. In this case, reduce the amount of coffee grounds being used. To prevent this issue, please make sure to use medium ground coffee and one of the recommended Basket Coffee Filters listed here.
A: The drip prevention mechanism may not be operating properly. Please make sure that the Drip Prevention Valve on the Filter Basket is assembled and attached properly. For EC-YSC100 and EC-YTC100 models, also make sure that the Carafe Lid Valve on the carafe lid is assembled and attached properly. If all parts are operating properly but coffee still overflows, please contact Customer Service here.
A: The noise that you hear while brewing is caused by the rapid heating of water. The Fresh Brew Plus Thermal Carafe Coffee Maker EC-YSC100 and EC-YTC100 are high-powered, and equipped with a long heater pipe that quickly heats large volumes of water, which may be perceived as loud. For a quieter brew, we recommend the EC-YTC100 and using the Normal brew mode.
