How To Fix Sud Error On Lg Washer

Steps to Resolve the SUD Error

1. Reduce the Amount of Detergent: Overloading your washer with detergent can result in an overabundance of suds, triggering the SUD error. To remedy this, carefully measure the amount of detergent you add. Refer to the manufacturer’s recommendations or adjust based on the level of soil in your laundry.




2. Choose the Right Detergent: Certain detergents may not be suitable for LG washers, leading to excessive suds formation. Opt for HE (High-Efficiency) detergents specifically designed for these appliances. These detergents are formulated to minimize suds while effectively cleaning your clothes.




3. Check for Detergent Residue: Detergent residue buildup in the washer can contribute to the SUD error. Perform a hot water cycle with an empty washer to flush out any accumulated residue. You can also use a specialized cleaning agent for washing machines to thoroughly cleanse the interior.




4. Inspect the Water Level Sensor: A malfunctioning water level sensor can provide inaccurate readings, causing the washer to overfill and generate excessive suds. Check the sensor for any obstructions or damage. If necessary, replace the sensor to restore proper water level detection.




5. Examine the Pressure Switch: The pressure switch monitors water pressure within the washer. A faulty pressure switch may misinterpret pressure levels, leading to the SUD error. Test the pressure switch using a multimeter to ensure its functionality.




6. Consider a Control Board Issue: In some cases, the control board responsible for regulating the washer’s functions may encounter a glitch. Resetting the control board can potentially resolve the SUD error. Unplug the washer, wait a few minutes, then reconnect it to reset the control board.




7. Seek Professional Assistance: If you’ve exhausted all the aforementioned troubleshooting steps and the SUD error persists, it’s advisable to contact an experienced appliance repair technician. They can accurately diagnose the underlying cause and provide a cost-effective solution.

Remember, preventing the SUD error is equally important as resolving it. Follow these simple tips:

• Measure detergent accurately.
• Use HE detergents designed for your LG washer.
• Clean your washer regularly to avoid detergent residue buildup.
• Address any water leaks promptly as they can affect water level readings.
• Schedule regular maintenance checkups to keep your LG washer in top condition.

By adhering to these recommendations, you can effectively eliminate the SUD error and enjoy the uninterrupted performance of your LG washer. Remember, tackling this issue is not as daunting as it may seem. With a little troubleshooting and preventive care, you can restore your laundry companion to its pristine condition and ensure years of efficient operation.
