What SUD means

On many Samsung washer models, SUD belongs to the excess suds category. The appliance is detecting too much foam, which can block normal draining or sensing.

Codes and exact steps can vary by model number, production year, and regional design. Use this guide as first-pass orientation and confirm model-specific details with the manufacturer source listed below.

Before you start

Write down the full model number and the exact display text before changing parts or clearing the control. Similar-looking codes can map to different model families, and a reset can erase useful timing clues.

If the appliance shows active leaking, a burning smell, smoke, gas odor, repeated breaker trips, or water near power, stop this checklist and use qualified service.

Model numbers affected

Commonly searched Samsung model families include front-load washers, top-load washers, high-efficiency washers, laundry centers, and compact models.

This is not a confirmed model-number list. Similar display codes can mean different things across model families, production years, and regional designs. Match the exact code to the full model number on the appliance tag before ordering parts or opening panels.

Common causes

• Too much detergent
• Non-HE detergent in an HE washer
• Soft water plus normal detergent amount
• Residue from prior cycles

How to check and fix SUD

1. Confirm the model number and exact code spelling.
2. Pause the cycle and let suds settle.
3. Run a rinse/spin or clean cycle without adding detergent.
4. Use less detergent on the next load.
5. Use HE detergent only when the washer requires it.
6. Run one controlled reset only when the appliance is dry, stable, and safe.
7. Stop if SUD returns immediately or appears on an empty test.

Safe checks before service

• Pause the cycle and let suds settle.
• Run a rinse/spin or clean cycle without adding detergent.
• Use less detergent on the next load.
• Use HE detergent only when the washer requires it.

What not to do

• Do not bypass locks, sensors, fuses, or leak protection to force a cycle.
• Do not open powered panels or touch wiring for a code check.
• Do not assume one display code proves one specific part has failed.

Stop and call a technician when

• Suds are not present but the code repeats.
• The washer will not drain after suds settle.
• You see water leaking from the door or dispenser.
