Abstract
A laundry washing machine and method utilize a fluid property sensor to dynamically select between different types of rinse operations, e.g., fill rinse operations or spin rinse operations, performed during a wash cycle.
Claims18
A laundry washing machine, comprising:
- a wash tub disposed within a housing;
- a fluid property sensor configured to sense turbidity and/or conductivity of fluid from the wash tub;
- and
- a controller coupled to the fluid property sensor, the controller configured to initiate a wash phase of a wash cycle to wash a load disposed in the wash tub, determine with a fluid property sensor a fluid property value associated with the wash fluid, and select between a fill rinse operation and a spray rinse operation for a rinse phase of the wash cycle based at least in part upon the determined fluid property value.
