Quick answer
Suds messages on Whirlpool washers: what each washer type does, plus detergent and bleach notes.
Model note: Whirlpool reuses codes across series and model years, so SUD may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this codemay mean.
A plain-language reading of the code — always confirm against your model’s documentation.
Mean
There are too many suds in the washing machine.
Seeing SUD, Sud or Sd on a Whirlpool washer? Suds are building up beyond what the washer can handle, and each design copes in its own way.
Top load models
A suds reduction routine starts by itself. The manual’s advice is to let the washer carry on.
Front load models
Excess suds stop the washer from spinning water out.
To fix that, it lengthens the rinse: tumbling stops, water is added, and the bubbles break.
Expect this stop-and-rinse pattern to repeat a number of times.
What to change
Dose HE detergent (concentrations like 2x, 4x, 8x) by the maker’s directions for soil and load size.
Save big pre-measured pacs for big or heavily soiled loads.
Avoid “no splash” or “easy pour” liquid chlorine bleach on front load washers, because its thickening agent may add suds; use regular liquid bleach instead.
More codes
The top load suds page is Sd, 5d. For items left in the drum, read about rL.
