When Does the SUD Error Code Occur?

The SUD error code appears when the washing machine detects an excessive amount of suds in the drum. This overproduction of suds can disrupt the machine's functionality, leading to cycle interruptions and triggering the error.

Components Involved in the SUD Error Code

Understanding the key components responsible for the SUD error is essential for troubleshooting. These include:

Component	Functionality
Detergent Dispenser	Releases the correct amount of detergent into the drum. Overfilling or using the wrong detergent can cause excessive suds.
Pressure Switch	Monitors the water level in the drum. If excessive foam builds up, the switch detects it and signals the SUD error to prevent potential damage.

How to Fix the SUD Error on an LG Washer

Resolving the SUD error requires addressing the root causes of excessive suds. Follow these steps:

1. Use High-Efficiency (HE) Detergent

Ensure that you are using a detergent specifically designed for high-efficiency washing machines. Regular detergent can create excess suds, leading to the SUD error.

2. Check Detergent Quantity

Review the detergent amount used per load. Follow the manufacturer’s guidelines and avoid overloading the dispenser. Adjust the quantity based on load size and soil level.

3. Run an Extra Rinse Cycle

If excessive suds appear during a cycle, pause the machine and run an additional rinse cycle. This helps remove excess detergent and minimizes suds build-up.

4. Clean the Detergent Dispenser

Regularly clean the detergent dispenser to prevent residue buildup. Remove any clogs that might hinder proper detergent dispensing.

5. Inspect for Detergent Residue

Check the drum and door seal for any leftover detergent. Clean these areas to prevent residual detergent from causing excessive suds.

6. Run a Tub Clean Cycle

Periodically run a tub clean cycle using a washing machine cleaner. This removes detergent residues and helps prevent mold or mildew formation.

Summary of the LG Washer SUD Error

The SUD error in LG washing machines is typically caused by excessive suds during a wash cycle. Using the correct detergent, adjusting detergent quantities, and maintaining a clean dispenser can help ensure smooth operation and optimal performance of your LG appliance.
