I returned home from vacation to find my Zoeller M267 2" .5hp pump (Mfg date: 0604) inoperative. The pump will not switch on. A power outage had occurred at some point during my vacation. I have verified that the outlet has power. I have since removed the pump, cleaned it of all debris, and power washed the body, float, and other external surfaces. The pump still will not switch on. Thank you in advance for your assistance
