System and method for dispensing product to a washing machine. A chemical dispensing system includes a system controller, machine interface, and pump controller that communicate through serial data buses. The system controller provides a user interface, retrieves washing machine status information from the machine interface, and issues product dispensing commands to the pump controller. The pump controller monitors pump status and dispenses product in response to commands from the system controller. The pump controller: (1) determines pump activation periods based on calibration data stored in a pump controller memory; (2) tracks pump usage and adjusts the activation period to compensate for pump wear as the pump ages; (3) disables the pump if conditions exists that preclude operating the pump; (4) monitors product levels, and (5) reports pump status to the system controller. Integral channels are included in the pump housing to provide stress relief to a squeeze tube.

The present disclosure relates to a laundry treating apparatus, including a tub provided inside a main body and a drum rotatably provided inside the tub; and a detergent supply apparatus provided to be inserted into or withdrawn from a front surface of the main body, and configured to supply laundry detergent to the tub, wherein the detergent supply apparatus includes a laundry detergent input pipe that allows laundry detergent being moved by the laundry detergent pump to pass through an upper portion of the wash water dispenser so as to flow into the housing through the wash water dispenser.

A laundry treating appliance having a trating chamber and a bulk dispenser and a user interface configured to provide an indication to the user related to the bulk chemistry dispenser and a controller coupled with the user interface and the bulk treating chemistry dispenser and configured to execute an operating cycle including controlling the treating chemistry meter to dispense the predetermined amount of treating chemistry and determine a number of doses of treating chemistry available in the bulk treating chemistry dispenser and method of determining the number of doses and the types of a treating chemistry available in the bulk dispensing system, and providing an indication of the determination on a user interface.
