Speed Queen Washer Error Code CAnt / OPEn

The CAnt / OPEn error code means the control board has tried to unlock the door but cannot confirm that the door lock has released. It is a door lock system fault that involves the lock assembly, the wiring connecting it to the control, or the control board itself. The washer displays this code to prevent operation until the issue is resolved.

No, you should not attempt to run the washer while this error is active. The control is unable to confirm the door lock is functioning correctly, and running the machine with a compromised door lock could be unsafe. Resolve the door lock fault before resuming normal operation.

A power reset may temporarily clear the error code from the display, but if the underlying door lock problem has not been repaired, the code will return as soon as the control attempts to unlock the door again. A reset is useful for confirming whether the fault is intermittent, but it is not a fix for a failed lock assembly or wiring issue.

Some aspects of this repair are DIY-friendly, such as inspecting and reseating the wiring harness connector at the door lock assembly. However, if the door lock assembly itself has failed or the control board needs replacement, those repairs require sourcing correct parts and basic appliance repair skills. If you are unsure about electrical testing, it is best to contact a qualified technician.

Repair costs depend on the failed component. A replacement door lock assembly typically runs between $30 and $90 for the part alone. If a control board replacement is needed, parts can range from $150 to $350 or more. Adding professional labor costs generally brings the total repair to somewhere between $100 and $500 depending on the diagnosis.
