Samsung Washer Error Code Auto-off error

The Auto-off error means the washer's control board attempted to shut the machine off three times through its programmed sequence, but the unit failed to power down each time. This indicates a fault in the power control circuit, most commonly involving the power relay on the main control board. When this error is active, only the POWER button remains functional. It is not a cycle or sensor error but a power system fault that requires component-level inspection.

The washer should not be run with an active Auto-off error. Since the machine failed to power down as commanded, running additional cycles before the fault is resolved could pose a safety risk or lead to further damage to the control system. Pressing the POWER button to attempt shutdown is the recommended first step, and the unit should remain unplugged until the fault is diagnosed and repaired.

Repair costs vary depending on the root cause. Wiring repairs or connector replacements are typically on the lower end, often in the range of $75 to $150 for a service call plus parts. Replacing the main control board is more expensive, generally ranging from $150 to $350 or more depending on the model and labor rates in your area. Getting a diagnostic from a technician before ordering parts is recommended to avoid unnecessary expenses.

Some basic checks, such as inspecting the wiring harness for visible damage or loose connectors, can be done without specialized tools. However, diagnosing and replacing a faulty relay or main control board requires comfort with electronics and appliance disassembly. If you are not experienced with internal appliance repair, calling a qualified technician is the safer approach.

A basic reset, such as unplugging the washer for several minutes and plugging it back in, may temporarily clear the error if it was caused by a transient software or power glitch. However, if the underlying hardware fault, such as a stuck relay or damaged control board, is still present, the error will return. A persistent Auto-off error requires physical inspection and likely part replacement.
