Replacing the pump motor would not cause your problem. Yes, HWH systems are self bleeding. Just extend and retract 4 or 5 times and that will remove any air. Replacing the Pump Motor would not cause air in the system. Creeping out or in with no visible leaks is one of the extend or retract solenoids. They are leaking internally. You can manually open both extend and retract and run the room for 15 to 30 seconds and if there is any trash on the needle valve , that usually removes it. If not you replace the retract valve.
