Before you replace it
- Check the arm for damage and free movement. Loading obstruction or a blocked water path can also cause poor washing.
Compare the actual package.
Compare the exact reference, quantity and model evidence before comparing cost. Retailer prices are dated observations; shipping and tax are extra unless the seller says otherwise.

Retailer links · affiliate tracking disabled. FitCertain does not sell these parts.Plan the replacement.
This is an overview for planning the work. Use your complete model’s service instructions for access, fasteners and final checks. The linked catalogs identify the part and may provide repair material for specific models; they are not instructions for every appliance.
- Access / difficulty
- Access and fasteners vary by model; use the model service instructions.
- Time
- No model-specific time estimate has been verified.
- Tools
- Use the tool list in the model-specific service instructions.
- Let the dishwasher cool and disconnect power before inspecting accessible components.
- Use the complete-model instructions to identify the lower arm and its retaining method; do not force a fitting based on another model’s video.
- Check for loading obstructions, visible debris and damage before removal. Follow the documented removal and cleaning procedure.
- Compare the replacement hub and contents, then attach the arm using the current part instructions; do not transfer obsolete hardware without checking.
- Confirm seating and unobstructed movement as directed, reinstall required components and use the normal closed-door check. Never bypass a door interlock.
This is a planning overview, not a complete service procedure. Stop for damaged wiring, gas odor, leaks or uncertain access; use qualified service.
Availability & number history

Availability can change. Check the current retailer listing; a missing listing alone does not prove that a part is discontinued.
A few useful answers.
Does finding my part number confirm compatibility?
No. Match the complete appliance model and its suffix against the documented model list. An unlisted model is unknown, not a confirmed mismatch.
Does this replace WD22X27724?
Yes. WD22X27724 is a documented older reference leading to WD22X33499. Check the current part instructions and your complete model.
Should I transfer the old heat shield?
GE states that the replacement design does not use the earlier heat shield. Follow the current part instructions rather than copying the old assembly unchanged.
Will it fix every poor-washing problem?
No. Loading obstructions and a restricted water path can also affect washing. Identify visible damage and follow the spray-arm diagnostic guide before ordering.
