One of the most common user frustrations is a clean light that continues flashing even after running a cycle. This occurs because Cuisinart units rely on a cycle-monitoring microswitch rather than optical clarity sensors. If the descaling sequence gets cut short or water drains too fast, the logic board keeps the warning active.
If your machine refuses to clear the warning light, reset the sequence: fill the reservoir with water, hold the "Clean" button down for three full seconds until it blinks rapidly, and hit "Brew." Let the entire cycle finish uninterrupted. If the indicator remains lit, unplug the unit from the wall outlet for a full 60 seconds to clear the internal capacitor memory, then plug it back in. Routine resets prevent system errors while keeping internal temperatures true to spec.
