Sud or Sd means WFW560CHW4 is extending the cycle to remove excess foam, commonly from non-HE detergent or too large a dose. Read the whole code and note the cycle stage before resetting. Begin with load, detergent, taps, hoses and closures; cabinet, wiring and motor work belongs to qualified service. Low-water front loaders cannot collapse high-sudsing detergent quickly, so pressure sensing and draining take longer. Visible stable foam and a long pause support Sud/Sd; an empty, foam-free tub with repeated code may indicate restricted draining instead. Let the automatic suds routine finish, then run rinse/drain with no detergent. For future loads use only HE detergent and reduce the measured dose for soft water or small loads. Confirm the door glass and drain water are foam-free. If Sud/Sd returns on a detergent-free rinse, check the drain route and call Whirlpool.
Models covered
Safety first
- Do not force a locked door or lid, bypass an interlock, remove cabinet panels or work under a washer that contains water.
What the symptom may indicate
Checks in the right order
- Confirm the pattern
Low-water front loaders cannot collapse high-sudsing detergent quickly, so pressure sensing and draining take longer.
- Prepare safely
Cancel the cycle, unplug the washer, close both water taps and let retained water cool before checking a hose, dispenser, door or lid.
- Apply the official check
Let the automatic suds routine finish, then run rinse/drain with no detergent. For future loads use only HE detergent and reduce the measured dose for soft water or small loads.
- Retest once
Confirm the door glass and drain water are foam-free. If Sud/Sd returns on a detergent-free rinse, check the drain route and call Whirlpool.
Stop and get qualified help when
- Stop for water under the machine, a hot plug, burning smell, damaged hose, locked closure after the documented wait or a code that returns after one reset.
Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
