How to Fix / Troubleshooting
Safety First: Turn off power at the breaker. Electrical work should comply with local codes; consult an electrician if unsure.
- Verify wiring: Open the electrical junction box on the heater and confirm that line, neutral, and ground are connected exactly as shown in the Rheem wiring diagram.
- Check polarity: Use a receptacle tester or multimeter to ensure hot and neutral are not reversed at the supply.
- Confirm grounding and bonding: Ensure the green or bare ground wire is securely attached to the heater's ground lug and that the bonding lug is connected to the pool bonding grid.
- Correct any miswiring: Rewire as needed, then restore power and check if E60 clears.
