Answer to continue safely
Is it safe to keep using?
Yes. The Sud code is informational and protective — it does not indicate a dangerous condition. You can continue using the washer after the suds clear. Simply adjust your detergent type and amount to prevent recurrence.
Can I reset the code?
Yes. The Sud code typically clears on its own once the washer completes extra rinse cycles. You can also power cycle the washer after 20-30 minutes to clear the code, then restart with no detergent on a rinse-and-spin cycle.
When to stop immediately?
Stop if you notice: Suds are leaking from the door seal onto the floor, The washer has been in Sud mode for more than an hour without resolution.
Symptoms You May Notice
Washer pauses mid-cycle and extends time
The cycle time on the display increases as the washer adds extra rinse phases to clear the excess foam.
Sud or Sd code on display
The control panel alternates between showing Sud and the remaining cycle time as the washer attempts to clear suds.
Visible foam through the door glass
On front-load models, excessive white foam is clearly visible through the door window, sometimes filling the entire viewing area.
Soap residue on clothes after cycle
Garments come out feeling slippery or with visible white residue, indicating detergent was not fully rinsed away.
Possible Causes
Non-HE detergent used
Regular (non-HE) detergent creates 5-10 times more suds than HE formulas. Samsung HE washers use 60-80% less water, so the reduced volume cannot dilute the excess foam.
DIY PossibleToo much HE detergent
Even with the correct HE detergent, using more than the recommended 1-2 tablespoons for a full load creates excessive suds, especially with soft water.
DIY PossiblePartially clogged drain path
A partial blockage in the drain filter or hose slows water removal, causing the remaining water to churn and create foam during agitation.
DIY PossibleSafe Checks You Can Do
-
1
Wait for suds to dissipate
Leave the washer door closed and wait 20-30 minutes. The suds will gradually break down on their own. Then run a rinse-and-spin cycle without adding any products.
Adding a cup of white vinegar to the drum can help break down stubborn foam faster.

2
Switch to proper HE detergent
Check your detergent bottle for the HE symbol (a lowercase "h" and "e" in a circle). Switch immediately if you are using regular detergent. Use no more than 2 tablespoons per full load.
Liquid detergent is less likely to cause Sud errors than powder in HE machines.

Clean the drain filter
Open the access panel at the lower-front, drain residual water, and clean the filter. A partially clogged filter can contribute to suds buildup.
Clean the drain filter monthly to prevent both Sud and 5E drain errors.
When to Call a Professional
Contact a qualified technician if:
- Sud code appears every cycle even with correct HE detergent and minimal dosage
- The drain filter is clean but the washer still creates excessive foam
- Clothes consistently have soap residue despite using the minimum detergent amount
