Methods for dispensing a treating chemistry in a dishwasher
First Claim
1. A method for treating dishes in a dishwasher having a treating chamber for receiving the dishes for treatment according to an automatic cycle of operation, the method comprising:
- supplying liquid to the treating chamber;
sensing a temperature of the liquid;
comparing the sensed temperature of the liquid to an enzymatic temperature threshold;
adjusting the temperature of the liquid toward the enzymatic temperature threshold when the comparing indicates the sensed temperature does not satisfy the enzymatic temperature threshold;
an initial dispensing of an enzyme into the liquid when the comparing indicates the sensed temperature satisfies the enzymatic temperature threshold; and
maintaining the temperature of the liquid to satisfy the enzymatic temperature threshold.

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.
