Laundry room retrofit. Maytag washer triggering Leviton AFCI. Alternatives?

The OP still hasn't told us how the work he did triggered the installation of the AFCI receptacle. From what I can see none of the electrical was changed.
It was considered a "change of use" for the room. Thus a code upgrade.

That said the AFCI never worked. Right now there's an AFCI and GFCI next to each other, with the laundry plugged into the GFCI.
