Jandy ePump 2.7 THP Variable Speed Pool Pump with Digital Control OV Error Fix: Over Voltage — Input Voltage Too High

The incoming electrical voltage exceeds the safe maximum for the variable speed drive — check voltage at the pump junction box with a multimeter; should be within ±10% of rated voltage (typically 230V ±23V); causes include utility voltage spikes, incorrect transformer tap setting on the home electrical panel, or wiring connected to the wrong voltage source; sustained over-voltage will damage the drive electronics
