Will newer Siemens AFCI/GFCI circuit breakers handle washing machine loads better than older versions?
The combination of GFCI and AFCI may sound like a good idea, but AFCI’s do not handle motor loads well and motor loads with wave shaping like variable speed on a motor load if just about to be assured of tripping a AFCI protection device. GFCI’s will usually do ok on small motor loads but I have seen them trip when the motor is turned off if there is a problem. In my state the washing machine is a dedicated load and can be a standard breaker if the NEC required device is known to be a problem. I would check your states amendments to the NEC since this is a new washer and hopefully you can swap the breaker out. I do promote whole house surge suppressors as the cheap plug in ones don’t last (if the plug in did work for a while a hole house suppressor will last longer.
