a perimeter fluid channel that is attached to an interior surface of the drum and extends around an outer circumference of the drum;
lifters that are coupled with the interior surface of the drum, the lifters extending from the perimeter fluid channel, wherein the lifters and the perimeter fluid channel define an interior flow space; and
a fluid inlet that extends through the stationary tub in a direction that is parallel with a rotational axis of the drum, wherein the fluid inlet is disposed proximate the outer circumference of the drum and aligns with the perimeter fluid channel of the drum, wherein wash fluid is delivered to the drum via the interior flow space and through flow apertures that are defined within the lifters, and wherein fluid is delivered through the lifters and into the drum as the drum rotates about the rotational axis, wherein the perimeter fluid channel includes an undulating wall that defines a narrowed configuration of the perimeter fluid channel proximate a respective lifter of the lifters, the undulating wall configured to bias the wash fluid toward the respective lifter during a rotational operation of the drum.
