Possible Causes
Moisture inside motor or drive, Damaged insulation on motor windings, Water in conduit or junction box, Faulty internal ground detection circuit
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker immediately. Do not operate a pump suspected of ground faults due to shock risk.
- Inspect for water: Check the motor housing, conduit entries, and junction boxes for signs of water intrusion. Dry any moisture and correct the source (cracked fittings, missing gaskets).
- Check bonding and grounding: Ensure the pump bonding lug is properly connected to the pool bonding grid and that the equipment ground is intact.
- Insulation testing: A qualified technician should perform a megohm test on the motor windings to verify insulation resistance to ground.
- Replace if needed: If insulation is compromised or Er6 persists, replace the motor/drive assembly. Also consider installing or verifying a GFCI breaker as required by code.
