Sud

The "Sud" error code on an LG washing machine indicates an excessive suds issue, meaning too much foam has built up during the wash cycle. This can happen for several reasons, but luckily, it's often a quick and easy fix!

Causes of the Sud Error:

  • Using the wrong detergent: 
    • Using non-HE (High Efficiency) detergent or using too much detergent, even HE detergent, can cause excessive suds. HE detergents are specially formulated to create less foam in washing machines.
  • Hard water: 
    • The minerals in hard water can react with detergent to create more suds.
  • Soil load: 
    • Heavily soiled laundry can require more detergent, potentially leading to excessive suds.
  • Faulty water inlet valve: 
    • In rare cases, a malfunctioning water inlet valve can allow too much water into the machine, contributing to the suds issue.

Troubleshooting the Sud error code in LG Washing Machine

  1. Turn off and unplug the washing machine.
  2. Let the suds settle for at least 30 minutes. 
    • This will allow the foam to dissipate naturally.
  3. Open the door and carefully scoop out any remaining suds. 
    • You can use a cup or spoon to remove them.
  4. Dilute the suds with hot water. 
    • Pour some hot water into the drum to dilute the remaining suds. Be careful not to overfill the machine.
  5. Try restarting the washing cycle on a rinse cycle or spin cycle. 
    • This will help remove any remaining suds without starting a full wash cycle.
  6. If the Sud error persists, try using a defoaming agent. 
    • These are readily available at most grocery stores and appliance retailers. Follow the instructions on the product carefully.
  7. Consult the user manual or contact LG support: 
    • If the above steps don't resolve the Sud error, refer to your user manual for specific troubleshooting instructions or contact LG support for further assistance.

Prevention tips:

  • Always use High Efficiency (HE) detergent and follow the recommended amount. Refer to the detergent manufacturer's instructions and your LG washing machine's manual for specific guidelines.
  • Treat hard water if necessary. If you have hard water, consider using a water softener or a special hard water detergent to prevent excessive suds.
  • Adjust the water level based on the laundry load. Don't overfill the machine, as this can contribute to suds problems.
  • Clean the detergent dispenser regularly. Detergent buildup in the dispenser can also lead to excessive suds.

By following these tips, you can avoid the Sud error code and keep your LG washing machine running smoothly
