Official support and model manuals
Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
What does Sd / SUD mean on a Whirlpool washer?
On many model families, Sd / SUD indicates that excess suds are slowing operation. Confirm the exact model and region because the same display can be used differently.
Can I clear Sd / SUD by unplugging the washer?
A short power reset may clear a temporary state, but it will not fix a blocked hose, leak, failed sensor, motor, heater, or wiring fault. Stop if the code returns.
Should I replace a part based only on the code?
No. A code identifies a system or condition, not always the failed component. Complete safe external checks and use the model-specific manual or qualified service.
