Abstract
A dishwasher has a treating chamber for receiving dishes for treatment according to an automatic cycle of operation and a dispensing system for storing and dispensing a treating chemistry to the treating chamber during the cycle of operation. The dishwasher may dispense a treating chemistry when a temperature of a liquid in the treating chamber satisfies a predetermined temperature threshold. The temperature of the liquid may be maintained to satisfy the predetermined temperature threshold for a predetermined period of time based on the treating chemistry.
Claims22
A dishwasher for treating dishes according to an automatic cycle of operation, the dishwasher comprising:
- a chassis;
- a tub mounted to the chassis;
- and
- a water supply circuit comprising:
- a household inlet fitting carried by the chassis,
- a conduit fluidly coupling the inlet fitting to the tub, and
