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.
