W10728160 Whirlpool Tines are replacement rack tines designed âfor use on Whirlpool-brand dishwashers; they consist⣠of teh vertical prongs or âgrouped prong assemblies that⣠secure⤠plates, bowls⣠and other âitems âin theâ dishwasher⣠rack. As a mechanical⢠rack component, these⤠tines⢠are âtypically âfabricated from steel and âfinished with a protective â˘polymerâ or vinyl coating to resist corrosionâ and to reduce chipping and contact damage to⢠dishware. Theyâ are â˘suppliedâ as individual âtines, clipped sectionsor kit assemblies sized âto match factory rack configurations.
Inside theâ appliance, the⣠tines form part âof the rack assembly and directly influence load â˘stability, item spacing and âŁthe â˘effective exposure of surfaces to wash and rinse jets.⢠Functionally they âŁinteract with the rackâ shelves, tine mounts or clips, rack rails and rollersand indirectly with the â¤spray arm⢠and âŁwater distribution âŁsystem because â¤improperly âpositioned or damaged items can block spray paths and reduce cleaning performance. Tines are also exposed to thermal and chemical⢠stress from hot water and detergents, making âthe âcondition⣠of their⢠coating and mounting hardware relevant âŁto long-term reliability and to â¤preventing rust or premature failure.
In this article readers willâ find a⣠technical â˘overview of the W10728160 tines including their intendedâ function⤠and â¤common mounting styles, guidance on modelâ compatibility and identifying the âcorrect replacement, typical failure symptoms (broken or⢠bent⤠prongs, coating â¤failure, rustor loose mounts), practical troubleshooting⢠stepsâ for⣠diagnosisand replacement considerations⢠such as matching coating,â clip typeand whether to replace individual tines or the entire rack section.

Function and Role of Dishwasher Rack Tines in âLoad Support, Drainage and Spray Pattern Management
The W10728160 âŁWhirlpool tines are âindividualâ prongs on the dishwasher rack that establish the â¤mechanical interface between⢠the rack and the â¤load. Functionallyâ they fix the â˘position and angle of plates, bowls and cookware âŁso âŁitems remain separated and supported under vibrational and hydraulicâ loads; tine stiffness, pitch (spacing) and tip geometry determine whether a plate sits⤠vertical, a bowl tilts for drainageor a panâ is cradled horizontally.â Technicians recognize âthat differences in tine shape and mounting-snapâin clips versus weldedâ stems-affect compatibility âwith âspecific rackâ assemblies⣠and influence âlongâterm behavior such as springback, âcoatingâ wearand the â˘tendency to deform underâ repeated loading.
Beyond basic loadâ support, tines actively manage drainage and spray distribution by creatingâ predictable⤠gaps and angles that let liquid evacuate by â˘gravityâ and allow âspray jets to access âboth sides â¤of a load. A âŁproperly configured set â¤of tines⣠reduces pooling in shallow basins and minimizes spray shadowing; conversely, â¤missing âor bent tinesâ produce localized spray shadows and⤠increased residue.Practical inspection steps for service are to verify tine âpitchâ against the original rack layout, confirm secureâ attachment of the â¤W10728160 Whirlpool Tines â¤to the rack rail,⢠and observe whether âdamaged tines coincide with specific cleaning failures (e.g., consistent soiling on the backside â˘of plates âor pooling in cup bases).
- Load support: stiffness,tip contact area,and âspacing â¤determine item orientation andâ stability.
- Drainage: tine spacing creates channels for gravity drainage and preventsâ liquid âtrapping.
- Spray management: alignment affects âspray access and shadowing, influencing cleaning uniformity.
- Compatibility: mounting style âŁand âcoating mustâ match â¤the rackâ to avoid premature wear or fit issues.

How the⤠W10728160 Whirlpool Tines Works Inside â¤theâ Appliance: Mounting, Materialsâ and Interaction with Racks and Spray â˘Arms
The W10728160 Whirlpool Tines⣠serve âas âthe structural tooth array on âŁtheâ dishwasherâ rack thatâ locates and⣠supports âdishes⢠while maintaining clearance for water flow. These tinesâ are typically â¤formed from stamped âmetal or molded polymer and finished âŁwith aâ protective coating to resist corrosion and abrasion; the specific W10728160 design matches the⤠rack’s tubingâ geometry and â˘mounting interface so each tine holds items âŁat a controlled pitch âŁand height.Functionally, the âtines⤠define the load envelope for items â˘and âcontrol the exposure of surfaces to⤠the spray⤠pattern-proper⢠orientation and intactâ coating reduce⢠local turbulenceâ and prevent spray-arm interference, âwhile⣠bent, missingor degraded tines create spray shadows and promote re-soiling âŁor unevenâ drying.
- Mounting types: welded tabs, âsnap-in âclipsor sleeve⢠anchors â˘that match⣠rack âtube diameter
- Common materials:⣠stainless or⢠carbon steel⢠with vinyl/epoxy âcoating,⣠or reinforced polymer
- Typical failure modes: bent tines, âcracked coating, clip fatigueand âdetachment âŁfrom â˘rack
- Operational âimpact:⤠altered spray coverage, physical contact âŁwith spray armsand â˘load instability
When assessing compatibility and â¤performing repairs, âverify the clip⣠geometry,⤠spacing between tinesand the profileâ that clears the⢠lower âand upper spray âŁarms;⣠replacements mustâ match these âdimensions to restore intended performance. for routine âtroubleshooting, inspect â¤the W10728160 Whirlpool â˘Tines for⤠coating breaks âor â¤clipped-clipâ wear, measure the distance from⤠tine base toâ rack planeand observe a short wash cycle âto confirm there âis no contact â˘with rotating spray arms; âreplacing individual tines or using OEM-matched assemblies âis the practical solution when deformation or corrosionâ impairs dish âpositioning or spray access.

Common Failure Symptoms, Corrosion Patterns and Mechanicalâ Wear of⤠Tine â˘Assemblies
The W10728160 âWhirlpool Tines â˘serve as the vertical supports that hold plates, bowlsandâ other dishware in the dishwasher rack,⤠and are designed to align with the ârack’s post sockets â˘and retaining clips. These tines are⢠typically a formed metal core with a protective coating and âare engineered to flex slightly under âload while â˘maintaining shape; compatibility âdepends on rack geometry and the âdesign of the retaining posts, soâ replacement should match the â¤original tine spacing, âŁstem diameter,⣠andâ mounting⢠method.â In practical use, ârepeated loadingâ of âheavy cookware, âmisuse (forâ example âwedging â¤large items between âtines)or aggressive⤠dishwasherâ chemistries can abrade the âprotective coating, â˘change the contactâ profile, âŁand eventually compromise the fit of the âŁtine â¤assembly within theâ rack.
Common failure symptoms arise from two interacting mechanisms:⢠coatingâ degradation that exposes the underlying metal, âŁand mechanical fatigue at stress concentrators such as bends âor the tine-to-post junction. Corrosion typically begins at âpoints where âthe coatingâ is breached and manifests as âlocalized pitting, rust âstreaking onto âdishesor undercutting â˘beneath the â¤coating; mechanical wear shows as permanent bending,â hairline cracks at the bend radius, broken postsor looseness of the tine in its socket. technicians should inspect â¤for both⢠the⢠visual⣠signs ofâ coating loss and âmechanical âfreedom of âmovement-loss of retention or excessive âdeflection under expected â¤loads indicates replacement rather than ârepair.
- Rust stains on âŁdishware or brown â¤discoloration at the tine tip
- Flaking orâ missing coating â¤exposing bare metal
- Permanent bending, brokenâ tine stems, â¤or loose mounting in the rack
- Localized pitting atâ theâ base or at grooves âwhere water accumulates
| Item | Description |
|---|---|
| Coating breach | Protective vinyl/epoxy âworn or chipped, exposing steel and âaccelerating pitting and surface corrosion |
| Mechanical fatigue | Cracks or bends at the tine âradius or post interface from repeated loading âorâ impact |
| Galvanic/crevice corrosion | Corrosion concentrated âwhere⣠dissimilar metals contact â˘or where water and detergent â¤concentrate, often at the âtine base |
compatibility, Replacement Considerations and Diagnostic/Installation Proceduresâ for W10728160â Whirlpool⤠Tines
The ⣠W10728160 Whirlpool Tines ⤠are replacement â˘tine assemblies âdesigned toâ support plates, bowls and other dishware⤠in compatible Whirlpool dishwashers; they â¤function as structural wire âuprightsâ with a protective⢠vinyl coatingâ that preventsâ marring and resists corrosion. â˘Compatibility depends âon theâ rack⤠mounting style – some racks use clipâin stems that engage âŁmolded sockets⣠while others âhave tines welded intoâ the rack frame – so⤠confirm whether the original is âa modular⢠stem or a welded wire before ordering. Measure âstem diameter andâ spacing and inspect anyâ retaining clips or rivets on the existing rack:⢠a stem that fits a âmolded socket⣠will often beâ a direct âdropâinâ replacement, whereas⢠a welded tine⢠requires cuttingâ the old wireâ out and installing a replacement⣠assembly âŁor aâ full rack if âŁreâwelding â¤is necessary.
Diagnosing⣠failed tines begins with a visual and mechanical inspection for broken wire,missing or hardened vinyl tips,and âloose or corrodedâ clips; symptoms include dishes tilting,rattling during âthe⤠wash cycle,or food â¤debris⢠trapped⢠in âbent tine crevices. âReplacement âandâ installation typically require removing the rack from âthe dishwasher,releasing retaining clips or cutting welded sections,fitting⢠the new stem into the socket and confirmingâ the clip âŁengagement⢠or rewrapping and recoating if a welded repair was performed. After installation, run a short cycle and⣠check for secure⤠seating and correct alignment; if vibration â˘or ârubbing âŁpersists, recheck spacing â˘andâ clip seating before returning⣠the rack to service.
- Key checks: stem diameter,⢠socketâ geometry, clip âcondition, vinyl⢠tip integrity.
- Common symptoms: leaning plates, increased noise,â cracked âvinyl tips, visibleâ bends or breaks.
- Tools commonly used: needleânose pliers, thin flat screwdriver â¤(for clips), wire⣠cutters, heatâshrink vinyl tips.
