How do I properly add liquid chlorine bleach to the washer?

If your model has a liquid chlorine bleach dispenser, pour the measured bleach directly into the dispenser and it will be automatically diluted during the wash cycle. If your model does not have a dispenser, let the washer fill and begin agitating, then add bleach 5 minutes into the wash cycle by pouring it around the agitator — never directly onto the load.
