The Sd (Suds) error on your Maytag Washer means the machine has detected excessive suds in the wash tub and has paused the cycle to run extra rinses and drain the extra foam. Switching to a high-efficiency (HE) detergent and using less of it usually solves the problem.

Error code Sd / SUDS
Meaning Excessive suds detected in the wash tub
Severity Low — the washer is protecting itself, no repair usually needed
Time to fix 10–30 minutes
Tools needed None (HE detergent recommended)

What the Sd error means

Maytag washers have sensors that detect how much foam builds up during a wash cycle. When too much suds is present, the machine can’t spin or rinse properly because the extra foam cushions the clothes and prevents normal water flow and sensing. When this happens, the control board displays the Sd (or SUDS) code and automatically runs additional rinse and spin cycles to clear the excess foam before continuing.

This isn’t usually a sign of a broken machine — it’s most often caused by using the wrong type or too much detergent. The washer is designed to self-correct, but repeated Sd errors can add extra time to your laundry and, if left unchecked, may cause long-term buildup inside the machine.

Common causes

  • Using regular (non-HE) detergent in a high-efficiency washer
  • Using too much detergent for the load size or soil level
  • Detergent pods or liquid not dispersing correctly before the wash starts
  • Washing a small load with a full detergent dose
  • Detergent residue buildup in the tub, drum, or dispenser drawer
  • Using bubble bath, dish soap, or other non-laundry cleaning agents by mistake

How to fix the Sd error

  1. Let the cycle finish: The washer will usually run extra rinses automatically to clear the suds. Avoid opening the door until the cycle completes.
  2. Switch to HE detergent: Check the detergent bottle for the “HE” symbol. Standard detergent creates far too many suds for efficient washers.
  3. Reduce the detergent amount: Use only the recommended dose for your load size — HE detergent needs much less than you’d expect, especially for small or lightly soiled loads.
  4. Run a clean cycle: Use the washer’s self-clean or tub-clean cycle with a washing machine cleaner to remove built-up residue that can trigger repeated Sd errors.
  5. Check the dispenser drawer: Remove and rinse the detergent drawer to clear any dried residue that could release too much soap at once.
  6. Rewash with less detergent: If clothes still feel soapy after the cycle, run a rinse-only cycle with no detergent added.

FAQ

Is the Sd error a sign my washer is broken?
No. In almost all cases it simply means too much suds was detected, usually from the wrong or too much detergent. The washer corrects for it automatically.

Can I open the door when the Sd code appears?
It’s best to wait until the cycle fully finishes. Opening the door mid-cycle can interrupt the extra rinse and spin steps needed to clear the suds.

Why does this keep happening even with HE detergent?
You may still be using too much detergent, or there could be soap residue built up in the tub. Run a tub-clean cycle and cut back on the amount you use, especially for small loads.
