A:Answer Hello there, Riss. Thank you for sharing your experience with us. We’re glad to hear your LG LDFN4542B Dishwasher has served you well over the past two years. We understand your situation with the flickering lights and power—let’s look into this together.
In many cases, flickering lights or power interruptions can be linked to a temporary electrical fluctuation or an issue with the outlet's power supply. We recommend checking if the dishwasher is connected to a dedicated 15-amp circuit without any extension cords or multi-plug adapters, as these can cause unstable voltage. It’s also helpful to perform a simple reset by turning off the circuit breaker to the unit for about 10 seconds, then turning it back on to reboot the control board.

If the issue happens again, we’d be happy to look further into it for you. Please send us a private message on Social Media @LGUSSupport and our team will be more than happy to assist you directly. We truly appreciate you being part of the LG family.
