(1) Words or conduct relevant to the creation of an express warranty and words or conduct tending to negate or limit warranty shall be construed wherever reasonable as consistent with each other; but subject to the provisions of this Article on parol or extrinsic evidence (RCW
62A.2-202) negation or limitation is inoperative to the extent that such construction is unreasonable.
(2) Subject to subsection (3) of this section, to exclude or modify the implied warranty of merchantability or any part of it the language must mention merchantability and in case of a writing must be conspicuous, and to exclude or modify any implied warranty of fitness the exclusion must be by a writing and conspicuous. Language to exclude all implied warranties of fitness is sufficient if it states, for example, that "There are no warranties which extend beyond the description on the face hereof."
(3) Notwithstanding subsection (2) of this section:
(a) Unless the circumstances indicate otherwise, all implied warranties are excluded by expressions like "as is," "with all faults," or other language which in common understanding calls the buyer's attention to the exclusion of warranties and makes plain that there is no implied warranty; and
(b) When the buyer before entering into the contract has examined the goods or the sample or model as fully as he or she desired or has refused to examine the goods there is no implied warranty with regard to defects which an examination ought in the circumstances to have revealed to him or her;
(c) An implied warranty can also be excluded or modified by course of dealing or course of performance or usage of trade; and
(d) In sales of livestock, including but not limited to, horses, mules, cattle, sheep, swine, goats, poultry, and rabbits, there are no implied warranties as defined in this article that the livestock are free from sickness or disease: PROVIDED, That the seller has complied with all state and federal laws and regulations that apply to animal health and disease, and the seller is not guilty of fraud, deceit, or misrepresentation.
(4) Notwithstanding the provisions of subsections (2) and (3) of this section and the provisions of RCW
62A.2-719, as now or hereafter amended, in any case where goods are purchased primarily for personal, family, or household use and not for commercial or business use, disclaimers of the warranty of merchantability or fitness for particular purpose shall not be effective to limit the liability of merchant sellers except insofar as the disclaimer sets forth with particularity the qualities and characteristics which are not being warranted. Remedies for breach of warranty can be limited in accordance with the provisions of this Article on liquidation or limitation of damages and on contractual modification of remedy (RCW
62A.2-718 and RCW
62A.2-719).
