in case you didn`t get the first question.
just bought a new 5XP from Home Depot to replace an older model in the house my son purchased a year ago. Installed as per instructions. Checked the voltage coming through, It registered 120V. Turned on ( water running ), ran fine. Shut off, turned back on. The drum(?) was trying to spin but could hardly move. The breaker ( on the unit ) kicked in. Reset, tried again, worked. Shut off, tried again, wouldn`t work, shut off breaker. Used the allen key to check the drum(?), no resistance whatsoever.
