Electrolux Dishwasher Error Codes

Electrolux Dishwasher Error Code Er-12

Error Code Er-12 occurs when the drain valve activates at a time when it should be in the off position. This unexpected behavior can disrupt the normal functioning of your dishwasher, leading to drainage issues.

  1. Immediate Action: As soon as you encounter Error Code Er-12, it is recommended to shut off power to the dishwasher to prevent any potential electrical issues.
  2. Check Drain Valve Wiring: Begin troubleshooting by inspecting the drain valve wiring. Look for any visible signs of damage, wear, or a possible short circuit. Faulty wiring can often be the root cause of the drain valve’s untimely activation.
  3. Replace Electronic Control Board: If the wiring appears to be in good condition, the next step is to replace the electronic control board. The electronic control board is a critical component that regulates various functions, including the operation of the drain valve. A malfunction in this board can cause the drain valve relay to get stuck, leading to Error Code Er-12.
  4. Continued Issues: If the problem persists even after replacing the electronic control board, it is advisable to consider replacing the drain valve itself. A stuck or malfunctioning drain valve can trigger the error code and may need to be replaced for the dishwasher to function properly.


In summary, Error Code Er-12 in Electrolux dishwashers is a drain valve position error that requires careful inspection and troubleshooting. By following these systematic steps, you can identify and address the root cause of the issue, ensuring that your dishwasher operates smoothly. Remember to exercise caution and, if needed, seek professional assistance for a thorough diagnosis and resolution of the Error Code Er-12.
