[0043] In one embodiment, the hot air drier module (136) allows the user to select an independent dry option. The users are provided with the flexibility to choose whether to activate only the drying option, independent of the wash cycle. The independent dry option allows users to selectively utilize the drying option, when necessary, irrespective of whether the wash cycle has been initiated.
The processing subsystem (105) includes an ultraviolet light module (134) operatively coupled to the hot air drier module (136). The ultraviolet light module (134) is configured to sterilize the plurality of cookware at end of washing cycle by exposing the plurality of cookware to ultraviolet light for a predetermined time period. In one embodiment, the predetermined time period is within the range of 3 to 4 seconds. The ultraviolet light module (134) includes an ultraviolet light lamp to irradiate ultraviolet light to the plurality of cookware. The ultraviolet light lamp is positioned on an upper surface of the wash chamber (120). The ultraviolet light emitted by the ultraviolet light module (134) acts as a potent disinfectant. As the plurality of cookware is exposed to ultraviolet light, it penetrates the surfaces, targeting and neutralizing potentially harmful microorganisms such as bacteria and viruses that may have survived the washing cycle. The purpose of ultraviolet light activation is to eliminate bacteria and germs, achieving a high level of hygiene and suggests a 99% reduction in bacteria and germs.
[0044] The processing subsystem (105) includes an alert module (138) operatively coupled to the hot air drier module (136).

In further embodiments, the user device may comprise one or more of touch screens, accelerometers, gyroscopes, cameras, microphones, global positioning system (GPS) devices, and so forth.
[0047] Let’s consider a scenario where user X loads a variety of cookware, including bowls, plates, cups, and cutlery, into a wash chamber (120) of a dishwasher (100). As User X initiates the washing process, the detection module (122) activates a plurality of sensors including a smart sensor and detects the levels of oil and stains on the cookware. Employing an artificial intelligence model, the detection module (122) dynamically analyzes the real-time sensor data during wash cycle. The AI model determines a plurality of parameters for effective cleaning, determining the plurality of parameters like a 15-minute washing time and the necessity for 4 rinse cycles. The detection module (122) doesn't stop there; after completing the rinse cycles, the detection module (122) continues monitoring water content. If it detects oil content it goes for further rinsing, it triggers one or more additional rinse cycles. This rinsing and washing are done by a plurality of showers. Upon completion of the wash cycle an ultraviolet light module (134), sterilize the cookware by exposing it to ultraviolet light for 3-5 seconds. Additionally, a hot air drier module (136) automatically initiates drying of the cookware.
