The Ultimate Guide To Lg Washer Error Sud: Causes And Solutions

When your LG washer displays the “Sud” error message, it indicates an excessive amount of suds or foam in the wash tub. This can hinder the washer’s performance and damage the machine or clothes.

Causes of Sud Overload

1. Using Too Much Detergent:

Exceeding the recommended detergent dosage can create excessive suds. Use only the recommended amount for the size of your load and water level.

2. Incorrect Detergent Type:

HE (high-efficiency) detergents are specifically formulated for use in high-efficiency washers. Using regular detergents can produce excessive suds in HE washers.

3. Hard Water:

Hard water contains minerals like calcium and magnesium that can react with detergent to form more suds. Consider using a water softener or adding a cup of white vinegar to the rinse cycle.

4. Dirty Washer Tub:

A buildup of detergent residue, dirt, or fabric softener can contribute to excessive suds. Clean the washer tub regularly using a cleaning solution or bleach.

5. Worn-Out Gasket or Seal:

A worn or damaged gasket or seal around the door or tub can allow water to leak out, causing an imbalance in the water-to-detergent ratio and leading to suds.

6. Faulty Pressure Switch:

The pressure switch monitors the water level in the washer. A faulty switch may send incorrect signals, leading to the washer overfilling or underfilling, which can affect the suds level.

7. Malfunctioning Control Board:

The control board is responsible for managing the washer’s functions. A malfunctioning control board can disrupt the detergent dispensing or water regulation, resulting in excessive suds.

Troubleshooting and Prevention

1. Reduce Detergent Amount:

Use only the recommended amount of detergent for your load and water level.

2. Switch to HE Detergent:

For HE washers, always use HE detergents designed for high-efficiency machines.

3. Clean the Washer Tub:

Regularly clean the washer tub using a cleaning solution or bleach to remove detergent residue and buildup.

4. Inspect Gaskets and Seals:

Check the gaskets and seals around the door and tub for any damage or wear. Replace if necessary.

5. Test the Pressure Switch:

Disconnect the washer from power and remove the back panel. Use a multimeter to test the continuity of the pressure switch. Replace if faulty.

6. Contact LG Support:

If the troubleshooting steps do not resolve the issue, contact LG support for assistance.

Alternatives to Fix the “Sud” Error

1. Dilute the Suds:

Pause the washer and add a few cups of cold water to dilute the suds. Resume the cycle and check if the error persists.

2. Use a Suds Reducer:

Add a suds reducer or defoamer to the wash tub to break down the excess suds.

3. Reset the Washer:

Unplug the washer for 1 minute and then plug it back in. This may reset the control board and clear the “Sud” error.
