The lower spray arm will not rotate, although the upper does, and water pressure seems fine. Little experience with dishwashers, and wonder where to begin!

Was unable to locate “how to” on site, but good job done. Jon Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic.
