Amana Washer Error Code LO

The LO code means the washer attempted to unlock the door three times and was unsuccessful each time. The control board stops retrying after three failed attempts and displays this code. It points to a problem in the door locking system, which includes the door lock assembly, its wiring, or the control board. The door will typically remain locked until the underlying issue is repaired.

No, you should not attempt to run a wash cycle while the LO code is active. The door lock is not functioning correctly, and the washer will not be able to secure or release the door reliably. Running the machine in this condition could result in the door opening unexpectedly during a cycle, creating a water leak or safety hazard. Resolve the door lock issue before resuming normal use.

Repair costs depend on which component has failed. A door lock assembly is typically a lower-cost part, and a DIY repair would keep costs minimal. If a technician is hired, expect to pay for both the part and a service call, which can range from around $100 to $250 or more depending on your location and the shop's rates. A main control board replacement is more expensive, with total repair costs potentially ranging from $200 to $400 or higher when including labor.

A knowledgeable DIYer can address this code by following the washer's Will Not Unlock troubleshooting steps. Start by inspecting the wiring harness and connectors at the door lock for damage or corrosion, as this requires no parts and can resolve the issue if a loose connection is found. If the door lock assembly itself has failed, replacing it is a moderately involved repair that many experienced DIYers can complete with basic tools. If the control board is at fault, that repair is more complex and may be better suited for a professional technician.

A reset may temporarily clear the code, but it will return if the underlying problem with the door lock system is not repaired. Resetting the washer does not fix a failed lock actuator, damaged wiring, or a faulty control board. The reset can be useful as part of diagnostics to confirm the fault is repeatable, but it should not be relied on as a solution.
