Unreadable Card (EC:20)

• Communication Issue: The control board is unable to read the information encoded on the chip card you inserted. This could be due to a few reasons:

Potential Causes

• Dirty Chip or Reader: Dirt, dust, or debris on the chip card or the card reader contacts might be preventing proper communication.
• Damaged Card: A physical scratch or damage on the chip of the card itself could be making the data unreadable.
• Incompatible Card (Less Likely): In rare cases, you might be using a card that is not compatible with your washer's payment system (if applicable) or specific cycle selection system.

Troubleshooting Steps

1. Clean the Chip and Reader: Use a soft, dry cloth to gently wipe the chip on your card and the contacts on the card reader slot of the washer. Avoid using any liquids or abrasive cleaners.
2. Try a Different Card: If cleaning doesn't resolve the issue, try using a different card to see if the washer can read it. This will help determine if the problem is with the specific card you were using.
3. Consult Speed Queen Support: If the error persists even with different cards, contacting Speed Queen's customer support is recommended. They can provide further guidance on your specific washer model, the card reader functionality, and potential solutions.

What to Avoid

• Forcing the Card: Avoid repeatedly inserting or forcing the card into the reader, as this could damage the card or the reader itself.
• Disassembling the Washer: Do not attempt to disassemble the washer to clean the card reader internally. Leave any internal repairs to a qualified technician.

By following these steps, you can potentially resolve the unreadable card error (EC:20) on your Speed Queen washer. If the issue persists after trying different cards and cleaning, consult Speed Queen support for further guidance or consider calling a qualified technician to diagnose the problem.
