E d21
The error code E d 21 or Ed, 21 on your Speed Queen washer indicates an Over Voltage DC Bus Error. This means the washer's control board detected an issue with the Direct Current (DC) voltage within the washer's electrical system. Here's an explanation of the issue, potential causes, and why consulting a qualified technician is recommended
Possible Causes of Over Voltage DC Bus Error (E d 21 or Ed, 21)
- DC Bus malfunction: The DC bus is a circuit within the washer that regulates the flow of DC power to various components. An E d 21 error suggests a problem with this circuit, potentially due to:
- Faulty Power Supply: A malfunctioning power supply board responsible for converting incoming AC (Alternating Current) to DC power could be causing the voltage issue.
- Control Board Issue (Less Likely): In rare cases, the control board itself might be malfunctioning and misinterpreting the DC voltage levels.
Important Considerations
- Electrical Components: The DC bus error deals with the washer's electrical system. Troubleshooting or repairs often involve electrical components.
- Safety First: Electrical issues can pose safety risks. It's crucial to prioritize safety and avoid attempting repairs yourself.
- Consult a Technician: Given the potential for electrical hazards and the complexity of the issue, contacting a qualified appliance repair technician is highly recommended.
What the Technician Can Do
- Diagnosis: The technician can use specialized tools to diagnose the root cause of the error (faulty power supply, control board issue, or other).
- Repair or Replacement: Depending on the diagnosis, the technician might repair or replace the faulty power supply board or, in less likely cases, the control board.
Safety Reminders
- Unplug the Washer: Before attempting any inspection, always unplug the washer from the power outlet to prevent electrical hazards.
- Leave it to the Professionals: Diagnosing and repairing electrical components in appliances should be left to qualified technicians to ensure safety and proper repairs.
- Do Not Use the Washer: With this error, avoid using the washer until a technician resolves the issue to prevent further damage.
By understanding the E d 21 error and prioritizing safety, you can take the appropriate action of contacting a qualified technician to resolve the issue and ensure the safe operation of your Speed Queen washer.
