Sud shows up on Maytag’s top-load HE washers when the machine senses more suds than it can rinse out properly. It’s not a mechanical fault, it’s the washer reacting to what’s in the drum. In nearly every case the cause traces back to detergent: the wrong type, too much of it, or built-up residue from past cycles.

Maytag Washer Error Code Sud (Excessive Suds)
Sud means the washer detected too many suds, almost always from using regular detergent instead of HE.
Meaning
Possible causes
No cause is certain until it has been checked on the appliance.
- Very likely Regular (non-HE) detergent used in an HE washer
- Likely Too much HE detergent for the load size or soil level
- Possible Old detergent residue built up in the dispenser or drum over time
- Possible Fabric softener overused alongside detergent
First checks
- Check the detergent bottle for the "he" logo. Regular detergent foams far more than an HE washer is designed to handle.
- Measure detergent against the load size marked on the cap instead of estimating by eye.
- Run an empty hot-water cycle with a washer cleaner to clear residue built up from past overdosing.
- Cut back fabric softener to the amount marked on the dispenser, or skip it for one cycle to see if Sud stops.
What not to do
- Adding more detergent to try to compensate for suds you can still see. That makes Sud worse and extends the cycle further.
- Switching detergent brands without checking for the HE label. Non-HE detergent from any brand can trigger this code.
An error code varies by brand
The same code can have a different meaning depending on the brand and model. Always check your appliance's manual before acting.
