This part is a replacement fabric softener dispenser for your washer. If your washer will not dispense fabric softener or detergent, or will not agitate, you may need to replace the dispenser. When it is working, the dispenser releases fabric softener during the wash cycle. You can find the dispenser screwed in to the top of the agitator. To replace the dispenser simply unscrew it, and replace it with a new one. This is an OEM part, and is sold individually.
