The error code EC:27 on your Speed Queen washer indicates a Diagnostic Test Card Write Failure. This signifies an issue during a specific diagnostic process.
Here's an explanation of the problem, potential causes, and why consulting a qualified technician is recommended
Diagnostic Test Card Write Failure (EC:27)
- Technical Test Error: This error code appears during a diagnostic test using a specialized card (not your regular chip card) that technicians use to assess the washer's functionality. The error suggests the washer's control board couldn't write data onto the diagnostic test card.
Potential Causes
- Faulty Diagnostic Card: The diagnostic card itself might be malfunctioning and unable to receive data properly.
- Control Board Malfunction: In some cases, the error might indicate a problem with the washer's control board hindering its ability to write data during the diagnostic test.
The EC:27 error code is typically encountered by qualified technicians during the service process. Since it involves a specialized diagnostic tool and the potential for a control board issue, user troubleshooting is not recommended.
Recommended Course of Action
- If You Encountered This Error: If you came across this error code yourself, it likely means a technician was running a diagnostic test and encountered this issue. The technician will likely interpret this code and proceed with their diagnosis.
- For Washer Malfunction: If your washer is malfunctioning and you haven't called a technician yet, contact Speed Queen Support. They can guide you through troubleshooting steps and determine if a technician visit is necessary.
