I seem to remember our NEMA rep stating that washing machines are now manufactured to specifically not trip GFCIs. I have an older washer (10years) on a GFCI of the same age, and it has never tripped while running.
PS. It was my wife's idea to put a GFCI for the washer. I told her that it was not required by code, but you know how that goes............
