Amana Washer Sud — What It Means & How to Fix It
Also shown as Sd, SUD on some models.
Too many suds — the Sud message means the washer added extra rinse to break down foam before it can spin.
What this code means
Sud — shown as Sd on some models — alerts you that the suds level is too high for the washer to spin water out properly. The washer automatically pauses tumbling and adds extra rinse water to break the bubbles, and that pause can happen several times. Excess suds usually come from non-HE detergent, too much detergent, or heavy liquid chlorine bleach containing a thickening agent. A restricted drain hose can also trap suds and delay the cycle.
Sud and Sd appear in Amana's official error-code tables for both front-load and top-load washers; the shared Whirlpool-family platform shows the related SUD form on older model lines with the same suds-protection logic.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Regular (non-HE) detergent in an HE washer | Very common | Yes — switch to HE detergent |
| Too much detergent for the load | Common | Yes — reduce the dose |
| Liquid chlorine bleach with a thickening agent | Occasional | Yes — use regular bleach |
| Kinked or partly clogged drain hose holding suds | Occasional | Yes — straighten or clear the hose |
What you can try yourself
- Let the washer finish its extended rinse — the pauses are the suds breaker working, not a breakdown.
- Switch to HE (high-efficiency) detergent and follow the dose for your load size.
- On front-load models, clean the dispenser drawer so detergent dispenses fully instead of pooling.
- Check the drain hose for kinks or clogs that trap sudsy water in the drum.
- If Sd repeats, run a rinse-only cycle with no detergent to clear the remaining foam.

When to call a technician
- Foam is leaking from the washer cabinet or door seal.
- The washer errors out repeatedly after several rinse attempts and won't finish a cycle.
Typical professional repair cost: $0 — self-correcting with HE detergent; $100–$250 if a drain restriction keeps suds trapped
Frequently asked questions
Is it safe to use regular detergent in an Amana HE washer?
No — Amana HE washers use far less water, so regular detergent foams too much. That is the number one cause of Sud. Always use HE detergent.
How long does the Sud rinse take?
It can add several minutes of paused rinsing while the washer breaks down the suds. That is normal — give it time and don't add more detergent.
