Whirlpool Washer Error Code AE

The AE code signals a communication error between the washer's main PBA and sub PBA, which are the two primary control boards. The machine cannot operate safely when these boards lose contact with each other, so it stops and displays the code. The fault is most often traced to a loose wiring connection or corroded terminal, though moisture damage to the sub board is also a known cause.

No, you should not continue running the washer while the AE code is active. The error indicates that the control boards cannot communicate, meaning the machine cannot properly manage cycle functions, motor speed, or safety interlocks. Operating the washer in this condition risks further damage to the electronics and could lead to unsafe behavior during a cycle.

A power reset, performed by unplugging the washer for a minute or two and plugging it back in, may temporarily clear the code if the communication disruption was caused by a momentary glitch. However, if there is an actual physical problem such as a loose connector, corroded terminal, or damaged board, the code will return as soon as the washer attempts to run again. A reset should be considered a diagnostic step, not a repair.

If you are comfortable working inside appliances, you can start by unplugging the washer and inspecting the wire harness connectors between the two control boards for loose or corroded contacts. Reseating connectors and cleaning corroded terminals sometimes resolves the error. However, if the sub PCB has been damaged by moisture or has internal component failures, board replacement is required and may be better handled by a qualified technician.

If the fix is simply reseating a connector or cleaning a terminal, you may have no parts cost at all, only the cost of a service call, which typically ranges from $75 to $150. If the sub PCB needs replacement, total repair costs including parts and labor generally fall in the range of $150 to $400 depending on your region and parts availability. Replacing the main PBA, if that board is at fault, can push costs toward the higher end of that range or beyond.
