GDT645SSN2SS: GE catalog dishwasher parts
GE Appliances Parts lists 14 selected components for exact dishwashers model GDT645SSN2SS across 1 diagram section(s): UPPER RACK ASSEMBLY. This reference preserves each position and original part number, then identifies a successor only where GE explicitly prints one. Match the full appliance label and assembly before ordering or requesting a service quote.
Safety boundary
- These entries identify catalog parts and give no removal, installation or internal repair procedure.
- The exact owner's manual controls accessible maintenance; use qualified service for electrical, gas, cabinet, pump, motor, control or internal work.
- Stop if the appliance label or observed part differs from the cited model/assembly.
Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.
Models explicitly covered
These model identities have the source evidence listed below. Read the part decision and suffix limits before ordering.
- GDT645SSN2SS · Check model references · Manufacturer evidence ↗
Required identifiers
- Complete appliance model label: GDT645SSN2SS
- Assembly section and diagram position
- Original part number and any explicitly listed successor
- Serial or production information if the manufacturer requests it
Compatibility rules
- Evidence applies to full model GDT645SSN2SS only; it does not establish another suffix or family member's fit.

Never assume
- A nearby suffix or shared model prefix uses the same components.
- A successor mapping can be reversed or extended to another model.
- A component in the diagram has failed or is safe to replace yourself.
- No successor shown means a part is available, discontinued, or interchangeable.
- Price and inventory remain current; check the manufacturer's live listing before purchase.
Read the correct assembly first
Confirm GDT645SSN2SS character-for-character on the appliance label, then open the cited GE diagram for the assembly that contains the observed component. A diagram position identifies a catalog row, not a fault code.
Compare the original number and any explicit successor independently. This page selects useful entries from the diagrams; it is not a complete service bill of materials.

Before ordering or requesting service
- Record the complete model label, assembly and diagram position with the part being compared.
- Use only the original or explicitly listed successor for this exact evidence record; ask GE to resolve any discrepancy.
- Check the live manufacturer listing for current availability and price.
- Confirm owner-accessible tasks in the exact manual; share these catalog details with qualified service for internal repairs.
