What it is
LG (Sud, OE), Samsung (SUd, LC) and Whirlpool (Sud, F9 E1) say excess suds can cause errors or slow draining. LG lists more detergent than recommended, non-HE detergent and powder in the liquid cup; Whirlpool lists non-HE detergent and "no splash" or "easy pour" liquid chlorine bleach.
How to choose
- Look for "HE" on the label.
- LG: fill liquid detergent only to the Max line; for powder, remove the liquid detergent cup; put at most one pod directly in the drum, never in the dispenser drawer.
- Samsung and Whirlpool: use the amount your manual gives and an HE detergent.
How it is tested
- Samsung says SUd means the washer detected over-sudsing, pauses briefly to let the suds dissipate, then continues the cycle on its own.
Capacitors can hold a charge after the power is off. Safety terms.
