I just bought a brand new washing machine and the hookups are located in the basement by a single GFCI outlet. This GFCI outlet is connected to a dual function AFCI/GFCI breaker. When initially plugging in the new machine, everything worked as expected. Meaning, the machine turned on and I was able to use if for several loads of laundry. One day the I realized that both the outlet and breaker (both GFCI protected) had tripped. Naturally, I reset both the breaker and the outlet. However, since then every time I go to plug in the machine there is a small spark and both the outlet and the breaker get tripped again.
I've tried running an extension cord to other outlets in the house, one of which is a standard outlet and the other which is a different GFCI outlet. Both of these outlets are on separate breakers from one another (both breakers are also dual function AFCI/GFCI) as well as the previous mentioned basement GFCI outlet. When plugging the machine via extension cord into the standard outlet everything works as expected. (It's my understanding that this is safe as the associated breaker is GFCI protected; Please confirm my understanding.) That said, when plugging in the machine via extension cord to the other GFCI outlet I get the same results as the basement GFCI outlet (small spark and tripping of the outlet and it's breaker).
It's my understand that a GFCI outlet connected to a GFCI breaker is redundant. That said, is it possible that the tripping of the outlet and breaker is a product of the redundant protection? If so, is it appropriate and safe to change out the basement GFCI outlet for a standard outlet? It seems logical to me as the breaker is still GFCI protected.
I should also mention that the house was built in 1945 and has somewhat dated electrical work, save the updated dual functionality breakers present.
I greatly appreciate any feedback/support and I thank you in advance.
Edit: I added a photo of the breaker in question. I'd greatly appreciate any follow advice base upon the type of breaker you see in the image here. Thanks
