Unplug the coffee maker and let it cool completely
Empty the carafe and remove any used coffee grounds from the filter basket
Fill the water reservoir with equal parts white vinegar and water (or use a manufacturer-approved descaling solution)
Place a clean empty carafe on the warming plate
Run a brew cycle until the reservoir is about half empty
Turn off or pause the machine and let it sit for 15–30 minutes
Resume the brew cycle until the reservoir is fully empty
Run 1–2 full brew cycles with clean fresh water to rinse out all vinegar
If the taste or smell of vinegar remains, continue rinsing with additional water cycles until clear
Wash the carafe, filter basket, and any removable parts with warm soapy water
Rinse thoroughly and dry completely
Wipe the exterior and warming plate with a damp cloth
Clean the showerhead/brewing area (if accessible) with a damp cloth or soft brush
If there’s a removable water filter, remove it according to the manufacturer’s directions and replace if required
Reassemble all parts and run one final short water-only brew cycle if recommended by the manufacturer
Repeat descaling every 1–3 months (more often if you have hard water)
