Sud or Sd corresponds to excessive suds in compatible Maytag washers. It can explain longer rinse cycles and clothes that end up too wet.
When the cycle time increases
The manufacturer documentation describes an automatic correction that alternates pauses and rinses. Let it finish if the behavior matches the manual and there are no leaks. Canceling and restarting repeatedly can leave that rinse incomplete.
Check what changed in the detergent amount
Review the HE product required by the machine, its concentration, and the actual amount of laundry. A measure meant for a full drum can be too much for just a few items. Include stain removers and other products added with the laundry in the check.
If the problem started after switching detergents, compare the dose with the previous one and do not simply reuse the same cap without adjustment. Also adjust for water hardness and soil level according to the package instructions. See how to fix excess suds to separate dosing from cycle recovery.
If it returns even after correcting the dose
Check for visible restrictions in the drain hose and note whether water remains along with suds. Repetition with the correct product requires service support. Do not add home remedies to neutralize the suds or turn Sud into a diagnosis of a faulty sensor.
The next load should use the corrected dose; an incomplete rinse can leave behind product from the previous attempt.
