What Sud
actually means.
Sud tells you the washer detected too much foam and has added a suds-reducing phase. The cycle runs longer, and if foam builds during a spin the washer stops so it does not push suds out.

What to do when Sud shows on the washerKind of codeMode, not a failure
Something the washer does by design, or a setting somebody turned on — a child lock, a prompt to run a cleaning cycle, a paused cycle waiting for the door. No part has failed and nothing needs replacing.
Usually leads toNo repair
Let the cycle finish; the extra phase can add about two hours.
Shows up asWasher Stops Mid-Cycle
The washer starts normally, then pauses, stalls or shuts off before the cycle ends, sometimes with water still inside.

Before you book,
in this order.
Each step comes from LG's own guidance for Sud on its washers. Follow it to the end: the last card says whether this is a visit.
Let the cycle finish; the extra phase can add about two hours.
Use high-efficiency (HE) detergent and stay at or below the dose on the package.
Run a Tub Clean if residue from earlier overdosing is suspected.
Cleared?
No part had to be replaced. If a later load stops with water left in the drum or the cycle halts again, treat it as a new problem.
What not to do
Sud is not a broken part. It is the washer correcting for too much detergent.
