If your Samsung washer flashes an Error Code SUD / 5UD / 5D / SD, you’re likely dealing with excess suds (foam) inside the machine. This can be frustrating, especially mid-cycle, and even more so when you’re unsure how serious the issue is. The good news? In many cases, this is something you can troubleshoot yourself. But when it’s beyond a DIY fix, you can rely on our local express repair technicians to get your washer running again, often with same-day service.
These error codes all point to the same issue: too many soap suds in your washer. Samsung uses different displays depending on the model, but they all essentially say the washer is trying (and failing) to rinse out excessive foam.
The washer typically tries to fix the issue itself by pausing the cycle to allow suds to break down. But if the foam doesn’t dissipate, it triggers the error.
Before calling in the pros, here are a few things you can try:
Give the machine 30-40 minutes after the error appears. Sometimes the foam clears naturally, and the cycle resumes.
Try running an extra rinse or spin-only cycle to clear out suds. Avoid adding more detergent.
Double-check the amount and type of detergent you’re using. Make sure it’s HE-certified and measure carefully—modern washers need much less soap than older models.
Run an empty tub clean cycle with washer cleaner or white vinegar. Excess soap residue can cause repeat errors even with correct detergent use.
A clogged drain filter can prevent proper rinsing, making foam issues worse. Clean out the filter (usually accessible from the front lower panel) and remove any debris.
If the error keeps returning even after adjusting your detergent use and running cleaning cycles, the issue could be more serious. A faulty foam sensor, malfunctioning drain pump, or deeper internal blockage may be to blame. In these cases, it’s best to call in a Samsung washer repair specialist near you.
