GE Dishwasher Lower Spray Arm (WD22X10047)

The GE Dishwasher Lower Spray Arm attaches to the bottom of the dishwasher tub and rotates during the wash cycle to distribute water across the lower rack. It receives pressurized water through a central hub and spins as water jets out through small holes, directing spray upward to clean dishes, pots, and pans loaded in the bottom rack.

The GE Dishwasher Lower Spray Arm can wear out or become damaged from repeated exposure to hard water minerals, food debris, and high heat over time. The small spray holes can clog with calcium buildup or food particles, the arm can crack from impact with large items in the lower rack, and the hub fitting can wear out and prevent the arm from spinning freely.

These symptoms can help you decide if the lower spray arm is the source of your dishwasher problem:

- Dishes in the lower rack come out dirty or with food still stuck on them

- Spray arm does not spin or rotates unevenly during the wash cycle

- Visible cracks, chips, or breaks along the arm or at the hub

- Clogged spray holes that cannot be cleared by cleaning alone

- Weak water pressure or uneven spray pattern at the bottom of the tub

- Unusual noise during the wash cycle caused by a loose or damaged arm
