Christina,
Here's a pic from an old thread showing the bleach dispenser arrangement on the A906, A806, and some other earlier models. Bleach poured into the dispenser goes into a reservoir mounted at front/right of the cabinet. It stays there until agitation starts, at which time a hose connected to an auxiliary port on the pump flushes water from the tub into the reservoir to displace the bleach and move it slowly into the wash water in the tub. It's a "timed" dispenser such that the bleach doesn't dump immediately and directly into the tub.
