A:Answer Hi Precisereset - While the sensors are not adjustable, to stop dispensing, press any pad, including the AUTOFILL button. For optimum results, use a uniform container between 4-8” tall and 2-6” wide. Some models may have a shorter recess, and therefore the maximum container height may be slightly reduced. Handles, straws, and garnishes on the rim of the container my cause overfilling or variation in fill volumes. Ice in container may affect fill volume. Keep sensors clean with a clean damp cloth, and do not spray liquid or cleaners directly on sensors.
