Can I fix LG code SUD myself?

Start with these safe checks: Use no more than the recommended amount of HE detergent, and cut back until there are no more suds. This isn't a fault.

When should I call a technician for code SUD?

This isn't a fault. Unplug it or switch the breaker off before you remove any panel. Don't test or replace wiring, control boards, heating elements or motors under power. If you see scorching, smell burning, or the breaker trips again, leave it off and call a qualified appliance technician or electrician.
