A laundry washing machine and method control a spin operation using a spin profile determined at least in part based upon a dynamically determined load type of a load being washed in the laundry washing machine. By doing so, the speed(s) and/or amount(s) of time in which a spin operation is performed may be customized for different types of loads, and in many instances, may reduce the amount of noise and/or energy consumption associated with spinning a wash tub during a wash cycle.

A laundry washing machine and method control a time or duration of a drain operation at least in part based upon a type of a load being washed in the laundry washing machine. By doing so, the amount of time in which a drain operation is performed may be customized for different types of loads, and in many instances, may reduce the amount of noise and/or energy consumption associated with draining a wash tub during a wash cycle.

Laundry washing machine with dynamic drain system

A laundry washing machine and method utilize a fluid property sensor to sense a fluid property of a fluid during a wash cycle to sense the level of detergent remaining in a load and control a rinse operation performed thereafter based upon the sensed fluid property. In some instances, the fluid property may be sensed while the load is being spun at a rate sufficient to cause fluid to be released from the load such that the sensed fluid property is based at least in part on fluid that was previously absorbed into the load. In addition, in some instances, the fluid property may be sensed during a spin phase of a wash cycle to selectively cause a wash cycle to selectively revert to an additional rinse phase when required, or otherwise proceed directly to the remainder of the spin phase to complete the wash cycle.

A laundry washing machine includes a weight sensing system including a weight sensor positioned to sense at least a portion of a weight associated with a wash tub and configured to output an associated pulse width modulated (PWM) force signal having a duty cycle that varies with applied force on the weight sensor. A controller of the laundry washing machine includes a state change sensing logic circuit coupled to receive the PWM force signal from the weight sensor and execute an interrupt service routine triggered by each state transition to capture a timestamp associated with each state transition such that the duty cycle of the PWM force signal may be determined using the captured timestamps.
