Frequently Asked Questions

Common questions about Samsung Sud error

HE stands for High Efficiency. It is formulated to produce very little foam, which matters because front-load washers like your Samsung use much less water than older top-loaders. Regular detergent creates a mountain of suds that the machine simply cannot rinse away — triggering the Sud error and potentially leaving soap residue on your clothes.

For most normal loads, about 2 tablespoons (the lowest mark on most HE detergent caps). If you have soft water, use even less — roughly 1 tablespoon. More detergent does not mean cleaner clothes. In fact, overdosing leaves a residue film on fabric and inside the drum that causes odor over time. Use the manufacturer's lowest recommended dose and increase only for heavily soiled loads.
