Yeah, misrepresentation is basic contract law stuff that would be generally valid in the US too, but:

1. there's probably no evidence of it

2. the workers at the store will deny it

3. the workers at the store likely have no grasp of contract law and will insist on whatever their store policy is

4. hiring a lawyer to return a dishwasher is a waste of time for most anyone knowledgable enough to know that this is a valid legal issue
