General Electric wd22x22879 Lower Spray Arm Assembly

Product Description

The General Electric wd22x22879 is a lower spray arm assembly designed as a direct OEM replacement for GE dishwashers. The lower spray arm rotates during the wash cycle and distributes water across the bottom rack, rinsing dishes, pots, and utensils. It mounts to the base of the dishwasher tub beneath the lower rack. This part is typically replaced when spray holes become cracked or clogged beyond cleaning, when the arm no longer spins freely, or when visible damage reduces wash performance. Installation is handled by appliance technicians or experienced DIYers familiar with dishwasher disassembly.

This lower spray arm assembly is intended for use in GE residential dishwashers. It sits at the bottom of the tub and is responsible for the primary wash coverage of the lower dish rack. A failed or damaged spray arm results in uneven cleaning, standing water on dishes, or incomplete rinse cycles. Replacing this component restores normal wash cycle water distribution without requiring full pump or motor service.

Key Features

• OEM GE replacement part engineered to factory fit and finish specifications
• Designed for lower tub position, providing full-coverage water distribution across the bottom rack
• Snap or twist-lock mount design typical of GE dishwasher lower spray arm assemblies
• Restores proper wash cycle performance when existing arm is cracked, clogged, or damaged

Compatibility

Designed as an OEM-style replacement lower spray arm assembly for compatible GE residential dishwasher models. Consult the appliance model and serial number plate before ordering to confirm fitment.

Installation Notes

Disconnect power to the dishwasher at the breaker or unplug the unit before beginning any service work. Remove the lower dish rack to access the spray arm mounting point at the base of the tub. The arm typically releases by rotating counterclockwise or pressing a center locking tab — do not force the mount. Reinstall by aligning the arm to the feed port and pressing or rotating until the locking mechanism seats fully, then confirm the arm spins freely before restoring power and running a test cycle.
