Leviton LED Power / Low-Voltage Supply Instability

Charger's status LEDs flicker or dim erratically while charging, but charging continues.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Weak low-voltage power supply on the control board, Loose low-voltage harness, Electrical noise from the line, Failing LED/UI board

Safety first: Turn OFF power at the breaker before removing any covers.

Steps:

1. Observe pattern: Note if the flicker correlates with other loads in the home switching on or off.
2. Check connections (qualified person): With the cover removed and power OFF, reseat the low-voltage connectors between the main board and the LED/UI board.
3. Inspect for damage: Look for bulging capacitors or burnt components on the control board.
4. If only the LEDs are affected: Replace the UI/LED board. If other functions are unstable, replace the main control board.
