I’ve had the unit for about 2 years with no previous issues. Power supply turns on, unit rolls forward smoothly at normal speed for about 10 seconds stops, and the power supply shuts off. Pulled the vacuum from the pool, cleared the propeller, removed tracks/rollers, cleaned out the little gunk/debris from all the different parts, gave it a rinse inside/out, put it back together and tried again with no improvement—it still rolls forward, stops and dies out after about 10 seconds. Anyone experience this or have any ideas on what to do or should I just call for service at this point?
