A removable non-integrated treating chemistry dispensing cartridge assembly may emit a signal in response to a predetermined amount of treating chemistry being detected and in response to a predetermined amount of illumination being detected.
1. A method of operating a dishwasher comprising a tub at least partially defining a treating chamber with an open face, a cover for selectively opening/closing the open face, a liquid system for supplying and recirculating liquid within the treating chamber, and a removable dispensing cartridge provided in the treating chamber, the method comprising:
detecting an amount of treating chemistry in the removable dispensing cartridge provided in the treating chamber;
detecting an amount of illumination in the treating chamber; and
emitting a human-detectable signal from the removable dispensing cartridge when the detected amount of treating chemistry is less than or equal to a predetermined amount and the detected amount of illumination is indicative of the open face being at least partially opened.
2. The method of claim 1 wherein detecting the amount of treating chemistry comprises detecting a level of the treating chemistry in the removable dispensing cartridge.
3. The method of claim 1 wherein the amount of illumination is detected with a photo-detector.
4. The method of claim 1 wherein the detected amount of illumination is compared to a reference value.
5. The method of claim 1 wherein the emitting a human-detectable signal comprises emitting at least one of a visible signal and an audible signal.
