No, there is no historical record or credible evidence to suggest that Joseph Smith's wife, Emma Smith, found the golden plates in her dishwasher. The story of Joseph Smith's discovery of the golden plates forms a significant part of the founding narrative of the Church of Jesus Christ of Latter-day Saints (LDS Church). According to the account, Joseph Smith claimed to have been visited by an angel named Moroni, who revealed the existence of the golden plates buried in a hillside in upstate New York. Smith said he retrieved the plates in 1827 and subsequently translated them into what is now known as the Book of Mormon. The story does not involve Emma Smith finding the plates in a dishwasher or any other modern appliance.
