Maytag Washer Error Code Su

Su on a Maytag washer means the machine has detected excess suds and has entered a suds reduction period. The display will alternate between 'Su' and 'dS' instead of showing the time remaining in the cycle. The washer is not broken and will resume the cycle automatically once the suds have cleared. This code is a protective response, not an error requiring a repair.

Resetting the washer will not address the underlying cause and may interrupt the suds reduction process the machine is actively performing. It is better to allow the cycle to complete so the washer can flush out the excess suds properly. After the cycle ends, focus on correcting your detergent type and quantity to prevent the code from returning.

In most cases, the Su code costs nothing to resolve since it is caused by detergent use rather than a faulty component. Switching to an HE detergent typically costs between $10 and $20 for a standard bottle. If repeated suds issues have caused secondary problems such as a control board fault or drainage issue, repair costs could range from $150 to $400 or more depending on the specific component involved and local labor rates.

The most reliable fix is to wait for the suds period to end, which the washer handles on its own. Going forward, switch to a detergent labeled HE and use only the amount recommended for your load size. If the code appears frequently, run a drum cleaning cycle to remove any detergent residue that has built up over time.

Yes, it is safe to leave the washer running when the Su code is displayed. The machine is operating as designed and is managing the suds condition on its own. There is no risk of damage to the washer or your laundry during the suds period. Simply allow the cycle to finish.
