Potential Causes

• Faulty Door Lock: The door lock itself might be malfunctioning and unable to engage or disengage properly.
• Broken or Misaligned Components: Internal components within the lock mechanism, such as linkages or springs, could be broken, misaligned, or jammed, preventing the lock from functioning correctly.
• Wiring Issues: In rare cases, there could be loose, damaged, or corroded wiring connections between the control board and the door lock mechanism.

Troubleshooting Steps

Important Note: Due to the potential for electrical components and the need for internal access, these troubleshooting steps are limited.

1. Unplug the Washer: Ensure the washer is unplugged before attempting anything for safety reasons.
2. Consult the Manual: Refer to your Speed Queen washer's user manual for any specific troubleshooting steps related to the door lock mechanism. Some manuals might suggest gently checking for obstructions around the door strike (where the lock meets the washer frame) but avoid forcing anything.

If the Error Persists:

• Contact Speed Queen Support: Since the error code points towards a hardware issue, contacting Speed Queen's customer support is recommended. They can provide further guidance and determine if the issue requires a qualified technician's expertise.
• Contact a Qualified Technician: Given the need for internal access and potential electrical components involved with the door lock, consulting a qualified appliance repair technician is highly recommended. They can diagnose the problem accurately (faulty lock, broken components, wiring issues) and recommend the appropriate solution (repair or replacement of the lock mechanism).

Safety Considerations:

• Avoid Electrical Work: Leave any disassembly or repairs to a qualified technician due to potential electrical components.
• Do Not Force the Door: If the washer displays this error, do not attempt to force the door open. This can further damage the lock mechanism.
