Applies to: Whirlpool top-load HE washer support article scope.Confidence HIGHLast verified 2026-07-25
Applies to
- Whirlpool top-load HE washers covered by the cited Product Help article
- Displayed Sud code in that top-load scope
Region: United States. This page does not generalize the code to every Whirlpool washer.
What the code means
There are excessive suds in the washer. In Whirlpool’s top-load HE scope, the listed action is to always use HE High-Efficiency detergent.
Confirmed: Whirlpool documents Sud for top-load HE washers as excessive suds. The official top-load article specifically points users back to HE High-Efficiency detergent use.
Can you keep using it?
Only after safe supply checks and only if the code clears.
When to stop
Stop using the washer if suds overflow, water leaks, the drum remains full of water, or the washer cannot complete a cycle safely.
When to call a professional
Contact service if Sud repeats after detergent correction or appears with draining, leaking or electrical symptoms.
Safe checks
- Confirm the detergent is marked HE.
- Use less detergent on the next load if the amount was high.
- Do not add extra detergent while the Sud message is present.
Confirmed by the manufacturer
- There are excessive suds in the washer.
- Non-HE detergent or too much detergent is compatible with the official HE detergent warning.
Commonly associated with this fault
- Soft water, concentrated detergent or a recent detergent change can be compatible with repeated excessive suds.
Not confirmed for this exact model
- A drain pump, pressure sensor or control failure is not confirmed by the cited top-load Sud row and should not be assumed from Sud alone.
Reset instructions
No reset procedure is published here because the current source does not document one for this scope.
Do not repeatedly restart with more detergent. If Sud returns after HE detergent and lower dosing, move to service diagnosis.
Information to collect before calling service
Record detergent brand and amount, whether it is HE, water level/load size, and whether Sud appears with drain or spin problems.
