Impact: Charging may still be safe, but user feedback is impaired.

Power cycle: Turn the charger off and on to see if the display recovers from a temporary glitch.
Check via app: Use the ABB app to confirm charger status if the display is unreadable.
Inspect connections (technician): Open the front panel and reseat the ribbon cable between the display and UI board.
Replace UI/display board: If the display remains dim or partially functional, replace the UI board or display module as per ABB parts list.

Charger’s display is very dim, flickers, or has missing segments, but charging still works.
