The dishwasher GFCI protection was adopted in the 2014 NEC. Also GFCI outlets are required to be readily accessible so they no longer can be located under the sink. The dishwasher also has to be AFCI protected so most are installing "dual purpose" AFCI/GFCI circuit breakers.

Some of my personal past experience with older GFCI receptacles is that they were notorious for nuisance trips for small motor starting. Usually changing the receptacle to a newer one solves the problem but not always. Sometimes switching between name brands helps...but not always.

I just recieved the 2015 IRC. The dishwasher GFCI requirement is listed. I have no experience with dishwashers on GFCI, but the one GFCI receptacle I installed continuously tripped. The washing machine was 25 years old and the trip occured when it would change wash cycles.

2014 edition of the NFPA 70. I'm guessing that if there is a "nuisance tripping issue", then there is good reason for the trip to have occurred.

We are in the process of adopting the 2017 NEC. One of the changes that I noticed between the 2017 NEC and the 2005 NEC (our current adopted code) is the GFCI requirement for dishwashers. Does anybody know what code cycle this requirement was added. It appears that this GFCI protection installation could cause nuisance tripping. Doe anybody have experience with the GFCI protection requirement for dishwashers. Thanks
