How To Fix The Samsung Washer SUD or 5UD Error Code?

Samsung washers can show the SUD or 5UD error code. This simply means that the washer has an excess of suds or soap. When this occurs, the washer will show the 5UD or the more common SUD error. The washer will add extra water and stop the wash so the soapy bubbles go away.

What is the Samsung Washer SUD or 5UD Error Code?

The SUD or 5UD error code is displayed on Samsung washing machines when there is an excessive amount of suds in the washer drum. This excess can cause issues with the washer’s normal operation, leading to longer wash cycles, poor cleaning performance, and potential damage to the washer. The error code is designed to alert users to this issue so that it can be resolved promptly.

Causes of the SUD or 5UD Error Code

There are several potential causes for the excessive suds that lead to a SUD or 5UD error code on Samsung washing machines:

1. Using too much detergent
2. Using the wrong type of detergent (non-HE detergent)
3. Overloading the washer with clothes
4. An issue with the washer’s pressure switch

Resolving the Samsung Washer SUD or 5UD Error Code

To resolve the SUD or 5UD error code on your Samsung washing machine, follow these steps:

Step 1: Check Your Detergent Usage

The most common cause of excessive suds is using too much detergent. Samsung recommends using HE (high-efficiency) detergent and following the manufacturer’s recommended dosage. Overusing detergent can lead to excessive suds, which can cause the SUD or 5UD error code.

• Measure your detergent carefully and follow the manufacturer’s instructions.
• Use HE detergent, which is designed for use in high-efficiency washing machines.
• Avoid using detergent with added fabric softener, as this can contribute to excessive suds.

Step 2: Avoid Overloading the Washer

Overloading your washer can cause the SUD or 5UD error code because it prevents the washer from properly rinsing and draining the suds. To avoid overloading, follow these guidelines:

• Do not fill the washer drum more than ¾ full.
• Wash bulky items, like blankets and comforters, separately from other laundry.
• Distribute clothes evenly in the drum to prevent an unbalanced load.

Step 3: Clean the Washer

Excessive suds can sometimes build up in the washer over time, even if you’re using the correct amount of detergent. To clean your Samsung washer:

• Run an empty wash cycle on the hottest water setting, using a washer cleaner or 1 cup of white vinegar.
• Wipe down the washer drum, door, and gasket with a damp cloth to remove any residue.

Step 4: Inspect the Pressure Switch

If the SUD or 5UD error code persists after following the above steps, there may be an issue with the washer’s pressure switch. The pressure switch is responsible for detecting the amount of water in the drum and can trigger the SUD or 5UD error code if it’s not functioning properly.

To inspect and clean the pressure switch:

• Unplug the washing machine and turn off the water supply.
• Locate the pressure switch, which is typically found near the top of the washer and connected to a clear hose.
• Remove the hose and check for any clogs or debris.
• Reattach the hose and ensure it’s properly secured.
• If the issue persists, consider replacing the pressure switch.

Step 5: Contact a Professional for Assistance

If the SUD or 5UD error code continues to appear after following the steps above, it’s time to contact a professional appliance repair technician. A technician can perform a thorough diagnostic of your Samsung washing machine and determine if there are any underlying issues that need to be addressed.
