My Intelliflow 011013 appears to have no power and where is has been coming on as programmed the last 12 years, it now is not coming on. I checked the breakers and the pool panel and everything seems to be okay. The control panel on the pump does not show a power light any more. Everything else works fine - the waterfall pump, the valve rotation, chlorinator, heater etc but that pump suddenly no longer works. Any suggestions on how to diagnose? Thanks.
