Open the washer's door and remove all articles of clothing from the washer's tub.
Insert your hand into the dispenser's hand slot and pull out the drawer. Pour the bleach into the bleach insert until the liquid fills to the top of the drawer's line.
Push the drawer slowly into the washer and press "Option" on the washer's control panel. Press "Tub Clean" and push "Start/Pause" to begin the tub cleaning cycle.
Open the washer's door after the cleaning cycle is complete to air dry the washer's tub. Ventilating the washer's tub eliminates moisture and prevents mildew from growing back in the washer.
