Abstract
A method of operating a dishwasher having multiple wash chambers, with each wash chamber executing a different cycle of operation, and liquid from one chamber may be reused in the other chamber.
Claims22
A method of operating a dishwasher having multiple treating chambers, comprising:
- a) determining which of the multiple treating chambers has a lightest soil load to define a treating chamber with the lightest soil load;
- b) implementing a wash cycle selected for the treating chamber with the lightest soil load by supplying a charge of treating liquid to the treating chamber with the lightest soil load;
- c) supplying the treating liquid from the treating chamber with the lightest soil load to another one of the multiple treating chambers;
- and
- d) implementing another wash cycle selected for the another one of the treating chambers using the treating liquid from the treating chamber with the lightest soil load;
- further comprising, confirming that a soil load of the treating liquid is less than a predetermined soil load threshold before at least one of c) and d);
- wherein, the confirming the soil load of the treating liquid comprises determining the turbidity of the treating liquid.

In a dish washing system having at least two, independently-operable treating chambers, and in each of which separate user-selected was cycles are implemented, a method of sharing a rinse liquid between the treating chambers during the implementation of the wash cycles, comprising:
- a) recirculating a wash liquid in each of the at least two treating chambers;
- b) determining which of the at least two treating chambers has a lightest residual soil load to define a treating chamber with the lightest residual soil load;
- c) supplying a rinse liquid to the treating chamber with the lightest residual soil load as part of a rinse phase for a wash cycle implemented in the treating chamber with the lightest residual soil load;
- and
- d) supplying the rinse liquid from the treating chamber with the lightest soil load to the other of the at least two treating chambers as part of a rinse phase for a wash cycle implemented in the other of the at least two treating chambers;
- wherein determining which of the at least two treating chambers has the lightest residual soil load comprises determining a turbidity of the wash liquid for each of the at least two chambers.
