The SUD error on your Maytag Washer means the machine has detected too many suds in the tub and has stopped the cycle to prevent overflow or poor rinsing. It’s often triggered by using the wrong detergent or too much of it, and can usually be fixed without calling a repair technician.

Error code SUD
Meaning Excess suds detected in the wash tub
Severity Low — usually a detergent or usage issue, not a mechanical fault
Time to fix 10–30 minutes
Tools needed None (occasionally a towel and warm water)

What the SUD error means

Maytag washers use a sensor that monitors suds levels during the wash cycle. When it detects an excessive amount of foam, it displays the SUD error and pauses the cycle, running extra rinses to clear the suds before resuming. This is a built-in safety feature designed to stop suds from overflowing out of the tub and damaging internal components or leaking onto your floor.

In most cases, this isn’t a sign of a broken machine — it’s the washer doing exactly what it’s supposed to do when it senses too much foam. However, if it happens repeatedly, it’s worth checking your detergent type and dosage.

Common causes

  • Using regular detergent instead of High Efficiency (HE) detergent in an HE washer
  • Using too much detergent for the load size or soil level
  • Washing with cold water, which prevents detergent from dissolving fully
  • A build-up of detergent residue inside the drum, dispenser, or drain hose
  • Overloading the washer, which limits water circulation and rinsing
  • Using bar soap, bubble bath, or non-laundry cleaning products by mistake

How to fix the SUD error

  1. Let the cycle finish naturally. The washer will often run extra rinse cycles automatically to clear the suds — avoid interrupting it if possible.
  2. Switch to HE detergent. Check your detergent bottle for the “HE” symbol. Non-HE detergent produces far more suds and is the most common cause of this error.
  3. Reduce your detergent dose. Use only the amount recommended on the packaging for your load size, not a generous guess — HE washers need much less than older top-loaders.
  4. Run a clean cycle. Use the washer’s dedicated cleaning cycle (or run an empty hot cycle with washing machine cleaner) to clear out built-up soap residue from the tub and dispenser.
  5. Cancel and restart if it’s stuck. If the washer won’t move past SUD, power it off, wait a few minutes, then select drain and spin to clear the tub before starting a fresh cycle.
  6. Check for other error codes. If SUD appears alongside other faults, it may point to a separate issue — codes like the ones covered in the Maytag Washer F1 Error Code: Causes and Fixes or Maytag Washer F5 Error Code: Causes and Fixes guides can help you narrow down the cause.

FAQ

Can I use regular detergent in my Maytag HE washer?
No. Regular detergent creates far more suds than HE washers are designed to handle, which is the leading cause of the SUD error. Always use detergent labeled “HE.”

Will the SUD error damage my washer?
No, it’s a protective feature. The washer pauses and runs extra rinses to clear excess foam rather than risk overflow or poor cleaning. It should resolve on its own once suds levels drop.

Why does my washer keep showing SUD even with HE detergent?
You may be using too much detergent for the load, or there could be a soap residue build-up in the tub or dispenser. Run a cleaning cycle and reduce your detergent dose to see if the error clears. If it persists, it’s worth comparing symptoms with related codes such as those in the Maytag Washer F2 Error Code: Causes and Fixes or Maytag Washer F3 Error Code: Causes and Fixes guides.
