The error code E Co or Er, Co on your Speed Queen washer indicates a Communication Error between the Machine ID Control (MIC) and the Front End Control (FEC) boards. These are critical control boards responsible for managing different aspects of the washing process, and the E Co code signifies they're not communicating properly.
Here's a breakdown of what it means, potential causes, and why consulting a qualified technician is recommended
Communication Error Between Control Boards (E Co or Er, Co)
The washer detects an issue with communication between the MIC and FEC. This could be due to several reasons:
- Incompatible Control Boards: A replacement control board might have been installed that isn't compatible with your specific washer model.
- Loose Connections: Electrical wiring connections between the control boards might be loose or damaged.
- Software Mismatch: The MIC and FEC might have different software versions causing communication issues.
- Faulty Control Board (Less Likely): In rare cases, a malfunctioning MIC or FEC could be the culprit.
Important Considerations:
- Limited User Repair: Diagnosing and resolving communication errors between control boards often involves technical knowledge and potentially replacing components. It's best to avoid attempting a DIY repair.
- Safety and Functionality: A control board communication error can prevent the washer from functioning properly and might even pose safety risks due to unexpected behavior.
- Consult a Technician: If you see the E Co or Er, Co error code, contacting a qualified appliance repair technician is highly recommended. They can diagnose the issue (incompatible control boards, loose connections, software mismatch, or faulty board) and recommend the appropriate solution.
Potential Solutions (by Technician):
- Replacing Control Boards: If the control boards are incompatible, the technician might need to replace one or both with versions that are compatible with your washer model.
- Securing Connections: In case of loose wiring, the technician can secure the connections between the MIC and FEC.
- Updating Software: If a software mismatch is identified, the technician might be able to update the software on the MIC or FEC (if applicable for your model).
- Replacing Faulty Board (Less Likely): In rare cases, a faulty MIC or FEC might need replacement.
Safety Reminder: Remember, communication errors between control boards involve electrical components. Leave the diagnosis and repair to a qualified appliance repair technician to ensure safety and proper repairs. Don't attempt to use the washer until the problem is resolved.
