Potential Causes

• Faulty Communication (Most Likely): The most likely cause is a temporary glitch or error in communication between the control board and another component. This could be due to loose connections, electrical fluctuations, or software issues.
• Faulty Component (Less Likely): In less frequent cases, the E:05 error might indicate a malfunctioning component within the washer that's sending incorrect data to the control board.

Troubleshooting Steps

1. Power Cycle the Washer: Turn off the washer at the wall outlet, wait for 30 seconds, and then turn it back on. This can sometimes clear temporary glitches affecting communication between components.
2. Check Connections (if comfortable): If you're comfortable and your user manual provides instructions, consult it for guidance on accessing specific connections within the washer (e.g., connection between the control board and another component). Carefully check these connections for any looseness or signs of damage. Only attempt this step if the user manual provides clear instructions and you are comfortable doing so.
3. Consult Speed Queen Support: If the error persists after power cycling and checking connections (if applicable), contacting Speed Queen's customer support is recommended. They can provide further guidance on your specific washer model and the E:05 error. They might suggest:
   • Additional troubleshooting steps based on your model's functionalities.
   • Scheduling a technician visit if the issue seems more complex and requires internal inspection or component replacement (e.g., a faulty sensor or control board).

What to Avoid

• Forcing the Washer: Avoid running the washer multiple times with the E:05 code present. This could further strain the washer's components.
• Disassembling the Washer (Unless Comfortable): Unless your user manual provides clear instructions and you're comfortable with appliance repair, avoid disassembling the washer to access internal components. Leave internal repairs to qualified technicians.

By following these steps, you can potentially address the invalid value communication error (E:05) on your Speed Queen washer. If the issue persists after power cycling and checking connections (if applicable), consult Speed Queen support for further assistance. They can help determine the cause of the communication failure and recommend the appropriate course of action.
