    Question:

    How does the GFCI protection requirement for receptacles within 6 feet of a sink apply to the new washing machines that have built in sinks?

    Answer:

    Hey Mike thanks for your question. It seems the rule applies the same way as for any other sink. 

    All 125-volt, 15- and 20-ampere receptacles within 6 ft of the top inside edge of the sink bowl in dwelling units must have GFCI protection as stated in 210.8(A)(7).
