Fatal IPM Over Current Shunt Error (E d 23 or Ed, 23)

• Motor Control System Malfunction: The error signifies a problem within the washer's Intelligent Power Module (IPM) or the current shunt circuit responsible for controlling and monitoring the motor's electrical current. This can lead to the motor not functioning properly or potentially overheating.

Potential Causes

• Faulty IPM: The IPM itself might be malfunctioning and sending incorrect signals to the motor.
• Shorted Current Shunt: A short circuit within the current shunt circuit could be providing inaccurate readings to the control board, causing malfunctions.
• Less Likely Causes: In rare cases, the error could be due to problems with motor windings or wiring.

Important Considerations

• Safety First: A malfunctioning motor control system poses a safety risk. Avoid operating the washer with this error.
• Limited User Repair: Diagnosing and repairing the IPM or current shunt circuit involves technical expertise and potential electrical work. User intervention is not recommended.

What to Do

1. Unplug the Washer: Immediately unplug the washer from the power outlet to prevent further electrical issues.
2. Consult a Qualified Technician: Contacting a qualified appliance repair technician is essential. They can diagnose the root cause of the error (faulty IPM, shorted current shunt, or other) and recommend the appropriate repair solution.

What the Technician Can Do

• Diagnosis: The technician will use specialized tools to diagnose the specific component causing the error.
• Repair or Replacement: Depending on the diagnosis, the technician might need to repair or replace the IPM, current shunt circuit, or potentially the motor itself (in rare cases).

Safety Reminders

• Do Not Use the Washer: With this error, avoid using the washer until a technician resolves the issue to prevent further damage or safety hazards.
• Leave it to the Professionals: Diagnosing and repairing the motor control system should only be done by qualified technicians with the necessary expertise and tools.

Remember: The E d 23 or Ed, 23 error on your Speed Queen washer signifies a serious issue that requires professional attention. Prioritize safety by not using the washer and contacting a qualified technician to diagnose and repair the problem effectively.
