Why Does My Samsung Washer Say Sud

A SUD error code on your Samsung washer means that the washer is detecting too many soap suds in the washer drum or, as Samsung describes it, an “over-sudsing condition.” Samsung washers have a foaming control function, which tries to reduce suds when detected but will show a SUD error if it fails to reduce them. The SUD code is displayed while the washer stops the cycle so that the suds can dissipate. The cause of the issue is usually the use of too much detergent or the type of detergent used.

What Causes the SUD Error Code?

1. Too Much Detergent

When doing a washing load, make sure to follow the detergent manufacturer’s instructions for the correct amount of detergent to use. If the SUD error code persists, a small reduction of the recommended amount of detergent may resolve the issue. Attention should also be paid to the concentration of the detergent, with the amount adjusted accordingly. Also, be aware that high-efficiency washers require less detergent than standard machines.

2. Type of Detergent

Samsung recommends using a high-efficiency (HE) detergent, which has low sudsing properties and is designed for high-efficiency washers. High-efficiency detergents are designed for modern washers that require less water. Detergents not designed for high-efficiency washers are more likely to cause the over-sudsing issue. A high-efficiency detergent is usually easy to spot, as it will have “HE” printed on the label. In addition to less suds, high-efficiency detergents should do a better job of removing stains and cleaning your clothes.

How to Resolve the SUD Error Code

When your Samsung washer gives you the SUD error code, leaving the washing machine to resolve the issue will usually resolve it. Once the washer detects the issue is resolved, it should automatically continue with the cycle.

Remove Detergent Residue

If you are using the correct amount of detergent and the detergent is an HE detergent, you may need to clear out detergent residue in the washer to fix the problem. To clear out detergent residue, run a long wash cycle, set to a high temperature, without any clothes in the washer. After the cycle, check that the washer is free of detergent residue. Clean away any detergent residue that remains.

Clean the Drain Pump Filter

Many Samsung washers that display the SUD error code will have a drain pump filter that can be accessed, removed, and cleaned. The SUD error can be caused by the buildup of suds and debris in the drain pump filter and cabinet.

To clean the drain pump filter:

1. Prepare a cloth and towel to absorb and wipe up the water that may leak out.
2. Prepare a shallow container or bucket to collect the water from the drain pump.
3. Locate the small access door, usually on the front of your washer.
4. Put the towel down on the floor beneath the access door.
5. Open the access door by pressing firmly against it.
6. Use the cloth to wipe up any water, and place it in the cabinet to collect water that may spill out.
7. Pull out the emergency drain hose, and position the spout over the container.
8. Remove the drain hose cap, and allow the water to drain into the container. When the water flow stops, leave the hose in the draining position for 15 minutes to ensure it is properly drained.
9. Unscrew the drain filter by turning it counterclockwise. Be careful not to break the plastic when turning the filter top.
10. Remove any debris from the filter.
11. Clean the filter and cabinet to remove debris, lint, and detergent residue. If it is difficult to clean, run hot water over the filter or soak it in hot water. Make sure the inlet and outlet holes are clear of debris.
12. Put the filter back into the washer. Turn the top clockwise until it clicks and is secure.
13. Put the cap on the hose and return it to its place in the cabinet.
14. Close the access door.

Check the Foam Level Sensor

If you have followed all of the advice above, the foam level sensor may be defective and falsely detecting suds in the tub. While instructions for testing and replacing the sensor are provided below, you should consider contacting a trained professional to check and replace the filter.

To check and replace the foam level sensor:

1. Disconnect the power supply to the washer.
2. Remove the top access panel on a front-loader washer or control panel and the rear access panel on a top-loader washer.
3. Locate the foam level sensor. Consult the washer’s manual if need be.
4. Disconnect the wiring harness and remove the sensor.
5. Test the foam level sensor with a multimeter to determine if it is defective.
6. If defective, replace the foam level sensor.

Error Codes 5D and SD

Instead of a SUD error code, some Samsung washers may display a 5D or SD error code. The 5D or SD error code is the same as the SUD error code. The washer has detected too many soap suds; it should pause automatically and wait for the suds to dissipate. Making sure you are using a high-efficiency detergent, not using too much detergent, removing detergent residue from the washer, and cleaning the drain pump filter should resolve the issue.
