Wash. Rev. Code § 78.52.470
Any person adversely affected by any order of the department may, within thirty days from the effective date of such order, apply for a hearing with respect to any matter determined therein. No cause for action arising out of any order of the department accrues in any court to any person unless the person makes application for a hearing as provided in this section. Such application shall set forth specifically the ground on which the applicant considers the order to be unlawful or unreasonable. No party shall, in any court, urge or rely upon any ground not set forth in said application. An order made in conformity to a decision resulting from a hearing which abrogates, changes, or modifies the original order shall have the same force and effect as an original. Such hearing shall constitute an adjudicative proceeding under chapter 34.05 RCW, the Administrative Procedure Act, and shall be conducted in accordance with its provisions.
