“CLEAN” or “CLEAN NOW” indicator stays on or flashes on KitchenAid drip coffee maker.

Perform a full cleaning/descale cycle:

• Fill the water reservoir with a 1:1 mixture of white vinegar and fresh water up to the MAX line.
• Place an empty carafe on the warming plate and ensure the brew basket is empty.
• Activate the CLEAN or DESCALE mode according to your KitchenAid model’s instructions (often by holding the CLEAN button).
• Allow the cycle to run completely. Do not interrupt power during the cleaning cycle.
• After completion, discard the solution and run 2–3 full reservoirs of clean water to rinse.

Resetting the CLEAN light:

• On many KitchenAid models, the CLEAN light will automatically reset after a full cleaning cycle.
• If it does not, unplug the unit for 5 minutes, plug back in, and run a normal brew cycle with water only.

If the CLEAN indicator remains on even after thorough descaling, the flow sensor or control board may be misreading flow and could require service.
