My big/Dreamspace naturally has a bleach compartment - being that it's practically the same as machine as its American cousins. The manual says to use LCB on a separate rinse cycle. However, the bleach dispenser is always flushed during the first rinse (and again during the final rinse) even though the manual does not mention this. I don't use bleach, though. But I could pour some vinegar in here...
