Samsung Washer Error Code AE6

AE6 indicates a communication error between the Inverter PBA and the main PBA. The washer cannot detect the expected signals between these two control boards and shuts down as a result. The cause is often a loose or faulty connector rather than a fully failed board. Checking the physical connections between the boards is the recommended first step.

No, you should not continue running the washer while the AE6 code is active. The communication failure between the Inverter PBA and the main PBA means the motor control system is not operating correctly. Running the machine in this state could cause further damage to the boards or motor. Disconnect power and address the fault before resuming use.

A power reset by unplugging the washer for a few minutes may temporarily clear the error display. However, if the underlying communication problem still exists, the AE6 code will return once the machine attempts to run. A reset is useful for confirming whether the fault is intermittent, but it does not fix loose connectors, damaged wiring, or faulty boards.

In many cases, yes. Start by unplugging the washer and locating the wiring harness that connects the Inverter PBA to the main PBA. Check that all connectors are firmly seated, the locking tabs are engaged, and there are no visibly damaged wires or corroded pins. If the connectors look intact, the repair may require soldering skills or board replacement, which typically calls for a professional technician.

If the fix is simply reseating a loose connector, there may be no parts cost beyond a service call fee, which typically ranges from $75 to $150. If the Inverter PBA needs replacement, parts and labor combined can range from $150 to $350. Main PBA replacement tends to be more expensive, often falling in the $200 to $450 range depending on the model and labor rates in your area.
