LG Washer Sud Error Code
Too many suds. What it means, which models show it, and how to clear it, easiest fix first.
The washer detected too much foam in the drum, almost always from using too much detergent or a non-HE detergent. It runs extra steps to break the suds down, which can add about two hours, and it may stop spinning to keep suds from leaking.

How to fix LG Sud
Let the washer finish
Allow the suds-reducing routine to run; the code typically clears on its own once the foam is gone. Run an extra rinse if suds remain.
Measure detergent correctly
Use only detergent labeled HE and follow the dosing line, or use a little less for small or lightly soiled loads. Highly concentrated detergents need even less.
Clean out residue
Run a Tub Clean cycle to flush leftover detergent from the drum and dispenser.
When to call a technician
If you see the code even with correct detergent amounts, have a technician check the pressure sensor and drain system.
