Abstract
A washing machine appliance may include a cabinet, a tub, a wash basket, an additive dispensing assembly, and a passive buffer compartment. The additive dispensing assembly may be positioned within the cabinet. The additive dispensing assembly may include a water supply valve, a water supply conduit, and an additive dispenser. The water supply conduit may extend between the water supply valve and the tub. The additive dispenser may be in selective fluid communication with the water supply conduit upstream of the tub. The passive buffer compartment may be disposed in fluid communication between the water supply valve and the additive dispenser. The passive buffer compartment may define an internal volume, a buffer inlet upstream from the internal volume, a dispenser outlet upstream from the additive dispenser, and a buffer outlet upstream from the tub in fluid parallel to the dispenser outlet to bypass the additive dispenser.
