Kenmore Washer Error Code FdU

FdU stands for a door unlock error. It means the washer attempted to unlock the door six times in a row and was unable to do so. The control board then stopped trying and displayed this code to indicate a failure in the door lock system. The cause is typically a mechanical or electrical fault in the door lock assembly.

No, you should not attempt to run the washer while this code is active. The door lock system is a safety interlock, and operating the machine with a compromised lock mechanism could allow the door to open during a spin cycle. Address the fault before resuming use.

Repair costs vary depending on the faulty component. A replacement door lock assembly typically costs between $30 and $90 for the part alone. If a technician is hired for diagnosis and installation, total costs commonly range from $100 to $250 depending on local labor rates and whether additional components such as wiring or a control board are also involved.

In some cases, yes. Start by inspecting the door latch area and the strike opening in the door gasket for any foreign objects that may be jamming the mechanism. If no obstruction is found, check the door latch hook and strike plate for visible damage. If the lock assembly itself has failed electrically or mechanically, replacing it is a repair many experienced DIYers can perform, as it typically involves disconnecting the harness and unbolting the assembly.

A reset may temporarily clear the code from the display, but it will return if the underlying problem is not repaired. The control board triggers FdU only after six failed unlock attempts, so the physical or electrical fault causing those failures must be corrected for the error to stay cleared.
