Speed Queen Washer Error Code EC:19

EC:19 means the washer's control board cannot detect communication with the card reader module. This error appears on Speed Queen washers equipped with card payment systems when the data link between the two components is broken or missing. It can be caused by a loose connector, a damaged harness, a failed card reader, or a faulty control board.

EC:19 is specifically related to the card payment system and does not indicate a mechanical or electrical hazard with the wash system itself. However, the card reader will not function while this fault is active, meaning card payments cannot be processed. Check with your specific installation setup before continuing operation.

Repair costs depend on which component has failed. A card reader module replacement will typically run in the range of $100 to $300 for the part, plus labor if a technician is involved. Control board replacement tends to be more expensive, often ranging from $200 to $500 or more for the part alone. Getting a professional diagnosis before ordering parts can help avoid unnecessary expense.

A power cycle is the first recommended step and will clear the error if the fault was caused by a temporary communication disruption. Power the unit fully off, wait a moment, then power it back on. If EC:19 returns after the reset, the fault is hardware-related and a simple reset will not resolve it permanently.

Start by performing a full power cycle to rule out a transient fault. If the error returns, inspect the wiring harness connecting the card reader to the control board, checking both connectors for corrosion, bent pins, or a loose fit. If the wiring is intact, replace the card reader first, as it is the more likely failed component. If the error persists after card reader replacement, the control board will need to be replaced.
