Ordered and replaced the aquastop and all appeared OK for a few loads. Now customer says it’s coming up with the same error code. Any clues please.

Customer buying new. Anyone need a brand new AQUASTOP 00678701? Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic.
