The error code E:SP on your Speed Queen washer indicates a Serial Communication Error. This signifies an issue with communication between the washer's main control board and the motor control board.
Here's an explanation of the problem, potential causes, and why it's important to consult a qualified technician
Serial Communication Error (E:SP)
- Communication Breakdown: The error code signifies that the main control board, which manages the overall washer operation, cannot properly communicate with the motor control board, responsible for regulating the motor's speed and direction during wash cycles.
Potential Causes
- Faulty Transformer: The transformer, which supplies power to the motor control board, might be malfunctioning or disconnected.
- Blown Fuse: A blown fuse on the motor control board could be preventing communication.
- Wiring Issues: Loose, damaged, or corroded electrical wiring connections between the control boards could be interrupting communication.
Important Note: Troubleshooting this error code requires accessing and potentially replacing electrical components. Due to the risk of electrical hazards, user troubleshooting is not recommended.
Recommended Course of Action
- Contact Speed Queen Support: Since the error code points towards a communication issue between control boards, contacting Speed Queen's customer support is highly recommended. They can provide further guidance and determine if the issue requires a qualified technician's expertise.
- Qualified Technician (Strongly Recommended): Consulting a qualified appliance repair technician is strongly advised. They have the expertise and tools to safely diagnose the problem accurately (faulty transformer, blown fuse, wiring issues) and recommend the appropriate solution (replacement of the transformer, fuse, or repair of wiring).
Safety Considerations
- Avoid Electrical Work: Diagnosing and repairing electrical components like transformers, fuses, and control board wiring should only be done by qualified technicians to prevent electrical hazards.
- Do Not Operate Washer with Error: With this error, avoid using the washer to prevent further damage to electrical components.
By following these recommendations and prioritizing safety, you can get the proper diagnosis and repair for the E:SP error on your Speed Queen washer. Consulting a qualified technician ensures the safe and effective resolution of this communication error between the control boards.
