Possible Causes
Tripped or open branch circuit breaker, Loose line connections at EVSE terminal block, Failed internal power supply on control board, Open thermal fuse on power board
How to Fix / Troubleshooting
Safety first: Treat all wiring as live until verified otherwise. Only a qualified person should remove covers or test voltage.
Steps:
- 1. Check breaker: Locate the dedicated breaker for the Leviton charger and ensure it is in the ON position. Reset if tripped. If it trips again immediately, stop and call an electrician.
- 2. Verify other loads: Confirm that other circuits in the panel are working to rule out a larger power issue.
- 3. Measure voltage at EVSE (electrician): With the cover removed, verify correct line voltage at the input terminals. If no voltage, trace back to panel wiring.
- 4. Inspect internal fuses: Some Leviton models include internal fuses or thermal links on the power board. If open, identify and correct the cause before replacing.
- 5. Control board power supply: If line voltage is present but the unit is dead, the low-voltage power supply on the main control board is likely failed and the board should be replaced.
