I saw an tread on this topic from 2015 but need more help. After a massIve storm pump not running showing error code 64 (short circuit). External hard wire ground was off and was reconnected. Previous post from Brett indicates after drying out he had to turn fan because pump stuck in between phases throws code 64. I tried this but no luck. Please advise step by step troubleshooting to resolve code 64. Thank you!
