Why an electrician
Supply wiring is not owner work. Switching the cooktop off at the breaker and leaving the checking to a qualified electrician is the sensible reading of the manual’s instruction.

Once the electrician has looked at the supply, LG cooktop repair is on hand through (415) 223-7887. Pass along the code, the model number and anything the electrician found.
Model compatibility: LG reuses codes across series and model years, so 6 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
