Before you replace it
- Support the main door and disconnect power before inspection. A heavy or dropping door can involve a spring, cable, hinge or mounting point. Have the balance system inspected before replacing a loaded spring; do not improvise spring tension or attachment points.
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.

Choose a listing only after resolving model fit and package differences. A lower price, familiar brand or similar photograph is not additional compatibility evidence. We have not physically tested these offers or ranked their quality.
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.
We have not reviewed a replacement procedure for this record. Ask the retailer for instructions covering your complete model before disassembly.
Availability & number history
Last status check: 2026-10-21. Catalog identity reviewed on the stated date. Live stock and delivery were not independently verified; check the retailer before ordering.
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 a similar model prefix confirm this part?
No. The fit check uses the complete model and revision listed in the evidence. An unlisted model is unknown, not a confirmed mismatch.
Has FitCertain tested this replacement on my appliance?
No. These are catalog relationships. Open the source links and read the confidence for your exact model; confirm compatibility, contents and return terms with the retailer before installation.
Does this spring open the detergent cup?
No. WD03X20445 is a main-door balance spring. The detergent-cup spring is a different component; GE WD3X764 has a separate record and model list.
Does the model list cover every GE dishwasher?
No. ADT521PGF0BS and the other complete models listed here are a reviewed subset. Keep the final revision and confirm the spring mounting, quantity and associated cable in the exact model diagram.
