Samsung Washer Error Code AE

The AE error code signals a communication failure between the sub PBA and the main PBA inside your Samsung washer. These two control boards must exchange data continuously for the washer to operate, and when that signal is lost or corrupted, the machine stops and displays AE. The cause can be a loose wire connection, moisture damage to the sub board, or a fault in the main PCB communication circuit.

A reset may temporarily clear the AE code, but it will return if the underlying cause is not addressed. To reset, unplug the washer for several minutes and then restore power. If the code reappears immediately or returns during the next cycle, a physical inspection of the wiring and boards is required.

If the fix is simply reseating a loose connector, there is no parts cost involved. Replacing a damaged sub PCB typically runs in the range of $80 to $200 for the part, while a main PCB replacement can cost between $150 and $350 or more depending on the model. Adding labor charges from a technician will increase the total cost.

In many cases, yes. Start by unplugging the washer and locating the wire harness that connects the sub and main PBAs. Inspect the connectors for looseness, corrosion, or bent pins, then reseat them firmly. If the connections look clean and secure, look for signs of moisture damage on the sub PCB. More advanced repairs involving board replacement are best handled by a technician.

No, you should not continue running the washer while the AE code is active. A communication failure between the control boards means the machine cannot reliably manage its functions, which could lead to incorrect water filling, improper spin behavior, or other uncontrolled operation. Leave the washer unplugged until the fault is diagnosed and corrected.
