Diagnostic Test Memory Test Failure (EC:29)

• 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 encountered a problem during a memory test within the diagnostic process.

Potential Causes

• Faulty Diagnostic Card: The diagnostic card itself might be malfunctioning and causing issues with the memory test.
• Control Board Malfunction: In some cases, the error might indicate a problem with the washer's control board memory, hindering its ability to perform the diagnostic test successfully.

The EC:29 error code is typically encountered by qualified technicians during the service process. Since it involves a specialized diagnostic tool, potential control board memory issues, and the complexity of interpreting memory-related errors, 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.

By understanding the meaning of the EC:29 error code, you can recognize when a technician encounters an issue during the diagnostic process. If you're experiencing washer malfunctions and haven't called for service yet, contacting Speed Queen support is the best course of action.
