Wash. Rev. Code § 29A.64.021
(1) If the official canvass of all of the returns for any office at any primary or election reveals that the difference in the number of votes cast for a candidate apparently qualified for the general election ballot or elected to any office, and the number of votes cast for the closest apparently defeated opponent is less than two thousand votes and also less than one-half of one percent of the total number of votes cast for both candidates, the county canvassing board shall conduct a recount of all votes cast on that position.
