Attempted to use our 2011 Eco-Jet Turbo last week. Though it started right up, it went for only 1-2 minutes before it stopped. The transformer is working and I see no issues with the cable to the unit. Not sure where to start. Impeller spins freely. Motor model is PM#A6022. No postings for this model to learn how to take it apart..... right now everything seems to be one unit. Any help would be greatly appreciated.
