Whirlpool WDT730HAMZ0 dishwasher racks, basket, and filters
Whirlpool's WDT730HAMZ0 model-specific parts page lists upper dishrack W11672788, silverware basket W11098065, pump/filter-cup assembly W10872845, and distinct screen filter WPW10463906. The cup and screen are separate parts; neither is a generic interchangeable filter. Use the full rating-label suffix: Whirlpool's Owner Center family page omits the final 0 and does not prove another suffix's part fit. Whirlpool's general filter guide describes owner cleaning for some removable triple-filter systems, but the exact model manual governs and the owner should stop if the visible filter geometry or release differs. Availability snapshots conflicted for the rack, so fit does not imply stock.
Safety boundary
- Read and compare the complete rating-label model before ordering.
- Remove dishes before any normal rack handling. Follow the exact Owner's Manual for stops and rails; stop if anything binds or needs prying.
- Filter cleaning is conditional on the visible removable filter matching Whirlpool's guide. Reinstall every filter fully and do not operate the dishwasher with a filter missing or loose.
- Do not open the pump, tub, wiring, cabinet, water connections, or other service-only areas.
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.
Required identifiers
- Complete dishwasher model from the appliance label: WDT730HAMZ0
- Which part is needed: upper rack, silverware basket, filter cup, or separate screen filter
- If an old filter part number is readable, record it before comparing replacement parts
Compatibility rules
- Whirlpool's exact WDT730HAMZ0 replacement-parts page lists W10872845 as a sump/pump filter and WPW10463906 as a separate sump-filter screen; its exact dishrack page lists upper rack W11672788 and silverware basket W11098065.
- KitchenAid/Whirlpool part detail identifies W11672788 as replacing W10847876, and the WDT730HAMZ0 exact-model page lists W11672788. This replacement relation is distinct from the WDT730HAMZ0 model fit listing.
- The fit scope is the complete model string WDT730HAMZ0 only. The WDT730HAMZ family page omits the final digit, so it does not extend these part rows to another suffix.
- Whirlpool's consumer filter guidance describes a removable triple-filter system, but owners must follow their exact manual and use the general steps only when the visible arrangement and release mechanism match.
Never assume
- WDT730HAMZ without the final 0 or another suffix is covered by this exact-model record.
- A filter cup assembly and screen filter are interchangeable or arrive together.
- A look-alike rack or filter fits because it has similar dimensions.
- A generic cleaning article overrides the appliance's own manual or establishes a repair procedure.
Exact model and listed parts
- WDT730HAMZ0 — Whirlpool quiet dishwasher with third rack; the suffix-specific parts page is the fit source.
- W11672788 — upper dishrack assembly.
- W11098065 — silverware basket.
- W10872845 — pump/filter-cup assembly.
- WPW10463906 — separately listed screen filter.
Filter parts and owner boundary
Whirlpool's comparison page describes triple filtration for the WDT730HAMZ product family, and the exact WDT730HAMZ0 parts listing names a filter cup and separate screen. Whirlpool's general consumer guide describes removal and rinsing for applicable removable filters and warns not to operate without filters correctly installed. The exact manual governs; do not force a release that looks different.
Availability and limits
Retail availability is not fitment. The exact-model listing and individual upper-rack product page showed conflicting status for W11672788 during review, so its current stock is unverified. The basket and filter part pages displayed in-stock states when checked, but status can change. No serial cut-in or alternate suffix fit was established.
