Electrolux's own owner-support article for the code SU dS covers too many suds on a front-loading washer, and the manual describes the oversuds protection: when oversudsing is detected the washer requires additional rinses until the suds are removed, and you can press Cancel to turn off the alert while it continues to rinse. The manual's fixes are to run a rinse cycle, use a low-sudsing high-efficiency detergent and use less detergent in future loads. The estimated cycle time may increase if oversudsing occurs, and non-HE detergent, overdosing and overloading also cause residue and odor in the gasket and dispenser.

Model-specific
What is true of this model and not of its siblings
- Detergent dosage
- Electrolux repeats HE detergent along with the recommended dosage in its odor, residue and oversudsing rows. HE detergents are designed for the small amount of water in a front-loader; a regular detergent or an overdose leaves suds that cannot drain away, which is why the washer must add rinses. Use liquid detergent or a non-precipitating water conditioner with powder in hard water.
- After a suds event
- Run a rinse cycle and then the clean washer cycle to clear residue from the drum and gasket, and clean the dispenser drawer of accumulated detergent. A washer that has oversudsed once is more likely to do so again if residue remains, and the residue also feeds the odor that the clean washer cycle prevents.
- Wrong products in the drawer
- Electrolux's residue table adds two dispenser-side causes for suds and residue: overfilled detergent and softener compartments, and detergent packs used wrongly. With a detergent pack, select the PODS option on models that have it and place the pack in the PODS compartment; adding more than two packs is a listed cause of a pack that does not dissolve, and the extra detergent then oversuds.
- Softener and rinse aids
- Large amounts of fabric softener residue in the dispenser drawer may indicate improper dilution or that more frequent cleaning is required. Softener that is poured straight on fabric causes stains, and overfilled compartments overflow into the drum. Because the fabric softener compartment is siphoned during the final rinse, an overfilled compartment can also deliver its contents too early and leave a film that resembles suds.
