Error codeSUD, Sud, Sd
ApplianceWasher
Three spellings, one problem: SUD, Sud and Sd all say the washer is holding more suds than it can manage. How it responds depends on whether it loads from the front or the top.
Front load behavior
Suds in excess leave the washer unable to spin the water out.
It compensates with a longer rinse: tumbling stops, fresh water goes in, and the bubbles collapse.
Expect that stop-and-rinse pattern a few times; it is needed.
Liquid chlorine bleach sold as “no splash” or “easy pour” has a thickening agent that can add to the suds. Use regular liquid bleach in the washer instead.
Top load behavior
A top loader showing Sud or Sd is reporting excessive suds and starts a suds reduction routine. Let it keep going.
Detergent habits that help
HE detergent is sold at 2x, 4x and 8x strength; dose to the soil level and the size of the load.
Overdosing means long cycles, oversudsing, poor rinsing and poor cleaning.
Reserve the larger pacs for large or heavily soiled loads.

Plain language
What this code means
SUD, Sud and Sd mean too many suds in a Whirlpool washer, which responds with extra rinsing or a suds reduction routine.
