A:Answer It's a reminder to descale the brewer.
Special cleaning of your 8 Cup Pour Over Coffee Maker is recommended depending on the frequency of use and quality of water used in the unit. If water in your area is especially hard, the following cleaning procedure should be performed more frequently, since minerals in water can detract from the flavor of the coffee and possibly lengthen brew time. While brewing, if the BREW/OFF power indicator light begins to flash, then the 8 Cup Pour Over Coffee Maker should be descaled.
Fill carafe with 1 part white vinegar to 2 parts cold water. Pour water and vinegar solution into the water reservoir.
Press and hold the BREW/OFF power button for 3 seconds until the BREW/OFF power indicator light slowly flashes. The 8 Cup Pour Over Coffee Maker will begin the CLEAN cycle until all water has been circulated and the water reservoir is empty. The BREW/ OFF power indicator light will turn off when the descaling operation is complete.
NOTE: Press the BREW/OFF power button at any time during the CLEAN cycle to turn the 8 Cup Pour Over Coffee Maker OFF. When liquid stops dripping from the shower head into the carafe, remove the carafe from the warming plate and allow liquid to cool for 15 minutes.
Rinse the unit by brewing a full carafe of cold water.
At end of BREW cycle, press the BREW/OFF button to turn the 8 Cup Pour Over Coffee Maker OFF. Discard water in the carafe. Wash carafe, permanent coffee filter, and filter holder in hot sudsy water. Dry parts thoroughly.
When Coffee Maker has cooled, wipe exterior with a dry cloth.
