What does LG Sud mean?

Excess suds detected: the washer adds a suds-reducing cycle (about 2 hours extra) and, if suds appear during spinning, stops to help prevent leaking.

Likely causes

  • More detergent than the manufacturer recommends
  • Non-HE detergent
  • Powder detergent placed in the liquid detergent cup

How to fix Sud: safe DIY steps

  1. Use no more than the manufacturer's recommended amount of detergent, and cut it back until the sudsing stops
  2. Use high efficiency (HE) detergent. For liquid detergent, fill only to the Max line; for powder, remove the liquid detergent cup
  3. If you use pods, put one pod directly in the drum before loading laundry (no more than 1 per load) and never in the dispenser drawer
Safety firstUnplug the washer (or switch off its breaker) and close the water taps before you reach behind it, handle hoses or open a filter. Water left from a recent hot cycle can be very hot, so let it cool first. Never bypass the door lock. Motor, pump, valve, sensor and control-board repairs belong to a qualified appliance technician.

Capacitors can hold a charge after the power is off. Safety terms.

When to call a pro

This is a detergent-use issue, not a repair; if it continues after you reduce detergent, request LG service.
