Speed Queen Washer Error Code EC:20
Unreadable card inserted into reader due to faulty card or dirty contact.
What the EC:20 error code actually means
Your Speed Queen washer tried to read the payment card you inserted but could not get a successful read from the chip. This is usually caused by dirt on the card's chip or inside the card slot. Cleaning the chip and slot contacts often resolves this, but if it keeps happening, the card itself may be faulty and need to be replaced.
