Whirlpool Dishwasher WP8561746, Replaces 8561746 Lower Spray Arm Fix Poor Performance Dishes Not Getting Clean
If your Whirlpool or KitchenAid dishwasher is leaving dishes dirty, spotted, or with food residue after a full cycle, a cracked, clogged, or broken lower spray arm is the most common cause. In most Whirlpool-built dishwashers, this is caused by a failed lower spray arm that can no longer spin freely or distribute water evenly across the bottom rack. When it fails, the lower rack receives little to no water pressure — leaving pots, pans, and plates dirty even after a full wash cycle. ⚡ One of the most common wear parts in Whirlpool, KitchenAid, Maytag, and Kenmore dishwashers. Part WP8561746 is the genuine OEM replacement lower spray arm that restores full water distribution across the bottom rack, returning your dishwasher to like-new cleaning performance.
