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.

Questions people ask about EC:20

What does EC:20 mean on a Speed Queen washer?
EC:20 means the washer's card reader attempted to read an inserted card but could not successfully retrieve the card data. The error is triggered by the card reader system when communication with the card's chip fails. This is typically caused by dirty contacts on the card or inside the reader slot, or by a card that is physically damaged or faulty. The washer will not start a cycle until a readable card is successfully processed.
Is it safe to keep using the washer when EC:20 appears?
EC:20 is a card communication error and does not indicate any mechanical or electrical hazard with the washer itself. The machine is simply preventing an unreadable transaction from proceeding. It is safe to attempt the cleaning steps and retry, and the washer will operate normally once a valid card read is achieved.
How much does it cost to fix an EC:20 error on a Speed Queen washer?
If the issue is dirty contacts, the fix costs nothing beyond a few minutes of cleaning time. If the card itself is faulty, replacement card costs vary by the card program in use at your location and are typically handled through the card program administrator. If the card reader hardware needs replacement, repair costs including parts and labor can range from roughly $75 to $250 or more depending on the reader model and service rates in your area.
How do I fix the EC:20 error on my Speed Queen washer?
Start by removing the card and wiping the gold chip contacts with a clean, dry lint-free cloth. Then carefully clean the contact area inside the card reader slot on the machine. Reinsert the card and try again. If the error continues, try a different card to determine whether the issue is with the card or the reader itself.
Will resetting the washer clear the EC:20 error?
A power reset alone is unlikely to resolve EC:20 because the error is caused by a physical issue with the card or the reader contacts, not a software glitch. The error will typically reappear as soon as the same unreadable card is inserted again. The underlying cause, dirty or damaged contacts or a faulty card, must be addressed before the error will clear.
