Seeing a cryptic error code flash on your Samsung washing machine display can be frustrating. Sud error on samsung washer, is one of the more common Samsung washer error codes, indicating an oversudsing issue. Too many suds in the drum can lead to poor wash performance, leaking, and other problems.
Fortunately, a SUD error is usually easy to fix yourself without a professional repair. With a few simple steps, you can get your Samsung washer functioning properly again. This guide will walk you through the causes of the SUD error and the various solutions you can try at home.
What Causes the SUD Error on Samsung Washers?
SUD stands for “Suds Detected.” This error points to an oversudsing condition inside your Samsung washer. Too many soap suds have built up, triggering the SUD sensor.
There are a few common causes of oversudsing and the SUD error:
Using Too Much Detergent
Adding too much laundry detergent is the most common reason for a SUD error. Modern HE (high-efficiency) detergents are formulated to produce fewer suds. Just a small amount is needed to effectively clean your clothes. Using traditional or regular detergents, pouring in too much detergent, or carryover suds from the previous cycle can all cause oversudsing.
Buildup of Detergent Residue
Detergent residue, lint, and other debris can accumulate inside your washer. The buildup occurs over time if regular cleaning is not performed. This buildup on components like the drum, pipes, and drain pump can lead to excess suds.
Problems Sensing Water Levels
Samsung washers use water level sensors to detect the amount of suds during the cycle. If these electronic sensors malfunction, the washer may incorrectly sense too many suds even with the right detergent amount. Faulty sensors are a less common cause of SUD errors.
How to Fix SUD Errors on Samsung Washers
If your Samsung washer is displaying SUD, there are a few simple troubleshooting steps you can take before calling for service:
1. Use High-Efficiency (HE) Laundry Detergent
The first step is to make sure you are using an HE-formulated laundry detergent, as recommended by Samsung. HE detergents contain suds suppressors to prevent oversudsing. They generate fewer suds that dissipate more quickly. Switching from a regular or traditional detergent to an HE detergent may solve the problem.
2. Use the Proper Detergent Amount
Refer to the owner’s manual for your Samsung washer to verify the correct detergent amount for the cycles you use. In most cases, you’ll only need 1-2 tablespoons of HE detergent for a standard load. Measure your detergent carefully based on load size using the detergent cup or cap. Never go above the max fill line.
3. Clean the Washer Cabinet and Components
Detergent and debris buildup inside the washer cabinet, pipes, drum, and other areas can contribute to excess suds. Give your Samsung washer a thorough deep clean:
- Clean the drum: Use a soft cloth and all-purpose cleaner to wipe out the washer drum. Pay special attention to the holes in the drum where lint and residue collect.
- Remove the dispenser drawer: Pull out the detergent dispenser drawer completely and clean it with warm water and a small brush. Wipe away any gunk or film from the drawer and housing.
- Clean the cabinet: Use an old towel to absorb any water that may drip and a soft cloth to wipe down the inside of the washer cabinet. Carefully dry all areas after cleaning.
- Clean the drain pump filter: Access and remove the drain pump filter and pipe. Rinse thoroughly under warm running water to remove built-up suds, lint, and grime.
4. Check and Clean the Drain Hose
Clogs or blockages in the drain hose can interfere with proper draining and lead to suds accumulating. Disconnect the drain hose from the back of the machine and inspect it carefully for obstructions. Use a hose brush or plumber’s snake to remove any trapped lint or debris. Reattach the drain hose securely.
5. Run a Rinse Cycle
After cleaning, run a rinse cycle with no detergent and no laundry load. This helps flush out any remaining suds and ensures your washer tub is clean for the next wash load. Select a high spin speed to remove as much water as possible.
6. Reset Washer and Retry
As a last resort, unplug the Samsung washer from its power source for 1 minute. This resets the control panel and can clear out the SUD error code. Plug it back in, then retry a normal cycle with HE detergent and the proper amount.
When to Call a Repair Professional
If the SUD error persists even after trying all these troubleshooting tips, some component of your Samsung washer likely needs professional service and repair.
Here are some signs it may be time to call a service technician:
- SUD error returns immediately after power reset
- Drain pump filter is severely clogged even after cleaning
- Drain hose is clear but water does not drain out completely
- Detergent dispenser not functioning properly
- Unusual noises during the wash cycle
- SUD happens even with no detergent added
In some cases, the water level sensor may be defective and needs replacement. Other electrical or mechanical faults could require component testing and replacement. A technician can diagnose the cause and make the proper repairs to get your Samsung washer functioning optimally again.
Preventing SUD Errors
Once you’ve cleared the SUD error, be sure to take preventive steps going forward:
- Use only HE detergent in the recommended amount
- Leave the washer door open between cycles to dry out inside
- Clean the washer cabinet, dispenser, and door gaskets monthly
- Always leave the door open slightly when not in use
- Clear water inlet filters as recommended
- Follow all care and maintenance instructions in your owner’s manual
With proper use and care, your Samsung washer should give you many years of dependable service without annoying SUD errors recurring. Stay vigilant and act promptly when a SUD error does pop up to keep your washer spinning happily load after load.
