1. A method of priming a tubing set and a dialyzer of a dialysis system, comprising the steps of:
connecting an arterial line of a tubing set to a venous line of the tubing set to form a continuous loop in the tubing set;
pumping air out of the tubing set with an air pump;
pulling a flow of fluid from a fluid source into the tubing set with the air pump;
operating a blood pump of the dialysis system in a forward operating mode to flow fluid from the fluid source into the tubing set in a first direction; and
operating the blood pump in a reverse operating mode to flow fluid through the tubing set in a second direction opposite to the first direction.
