W10728160 Whirlpool Tines are the individual âprong elements used on dishwasher rack assemblies to support and separate dishes, glasswareand utensils during a wash cycle. The⤠component is⢠typically a molded plastic or polymer-coated⤠steelâ tine that mounts into a âŁrack grid or âforms part of a replaceable tine row; it is indeed a passive mechanical part rather⢠than⤠an electrical or electronic device.
Inside âthe appliance the tines serve several practical functions: thay position and stabilize loads to âprevent contact, chipping, âor shifting during wash âŁand drain cycles; they maintain clearanceâ for spray⤠arms and allow âunrestricted water and detergent⤠flow around items; and theyâ interface mechanically with theâ rack structure â¤and any tine-retention clips âŁor molded â¤sockets.â Material selection, coating integrity, âŁtine spacing and attachment method âaffect⢠corrosion âresistance, thermal and chemical âdurabilityandâ the rack’s load pattern-factors that influence cleaning âeffectiveness, noise and⣠vibrationand the⤠likelihood of mechanical failure under repeated cycles.
In this article readersâ will find aâ focused â¤technical overview of W10728160 functionality and where itâ is typically used withinâ Whirlpool dishwasher rack systems,guidanceâ on identifying compatible racks and attachment types,common failure symptoms and⢠inspection checkpoints,basic troubleshooting âŁsteps to isolate⢠tine-related problems,and practical considerations for replacement or repair (including matching material/coating and secure mounting).The data âis intended to help technicians,engineers and appliance owners assess âserviceability and make informed decisions about replacement and preventive maintenance.

Function and Mechanical âRole of Dishwasher Tines⢠in Load Support and Spray Access
The primary mechanical role ofâ the⤠W10728160 Whirlpoolâ Tines is to secure and separate⤠items so⢠water and detergent can reach all exposed surfaces whileâ minimizing obstruction of spray patterns. These tines â˘are typicallyâ coated steel rods formed into a âgrid pattern that supports vertical loads from plates, bowls and some cookware; the geometry-spacing, heightand tip profile-controls how items areâ presented⤠toâ the spray arms and how runoff drains. Correct-tine geometryâ reduces the incidence of nested items and shadowing, so even small changes in tine pitch or a bent tine can significantly affect cleaning performance and âbreakage risk.
- Spacing/pitch: determines âitem⤠separation and spray access
- Material/coating: â˘affects stiffness, corrosion resistanceand friction
- Mount style: âfixed posts âŁvs. fold-down⤠hinges influence rack reconfiguration
- Tip⣠shape: rounded âvs. flattened tips change contact â˘points and sliding behavior
- Stiffness/load capacity: governs bending underâ typical dish loads
Mechanically, tines⣠act as cantileverâ supports; underâ load they âcreate bending moments at the base or hinge, âso failures typically present âas permanent bend, fractured weldsor broken coating that exposes substrate to corrosion. For technicians and repairers,⤠practical checks include â¤verifying âthat replacement tines seat into âthe sameâ retainer slots â˘andâ clips used by the original rack, measuring âthat occupied spacing matches OEM âŁtolerancesand confirming spray-arm âclearance⢠with a fully âloaded rack. âCommon service actions are âstraightening deformed tines only if the coating remains intact and replacing assemblies like W10728160 when⤠the mount interface or coating isâ compromised; a replaced tine that⣠restores original pitch and clearance usually returns the rack to expected cleaning performance.

How the W10728160 Whirlpool Tines Works Inside the â¤Appliance: âMounting, Materialsand interaction with Racks and⢠Spray Arms
The â¤W10728160 Whirlpool Tines is a replacement âtine âassembly designed to secure dishes in dishwasher racks and maintain consistent spacing for water âflow. The component â¤typically mounts to âtheâ rack âŁframe⣠with snap-fit clips or rivetedâ posts; some âŁrack variants use⣠keyed sockets where the âtine stem clicks into place. Materials are commonly stainless steelâ wire with a thin PVC or nylon âdip-coating for corrosion resistance and to protect âdishware, although some OEM-style replacements use⤠molded glass-filledâ nylonâ for increased impact âŁtolerance. Under âload the⣠tines must âresist bending âat⣠the primary bend points and at theâ mounting interface; technicians should inspect⢠for coating abrasion, stress fractures where the wire is bentand clip â˘fatigueâ during diagnosis. For âpractical replacement work, verify the W10728160 Whirlpool Tines part number against the appliance model and check â¤whetherâ the rack uses removable tine modules or permanently âcrimped tines to select the correct repair â¤method.
- Mount type: âsnap-in clip, rivetor âŁkeyed socket
- Material/coating: âstainless steel wire with PVC/nylon dip or molded nylon
- Common âfailure modes:â bent wire, coating wear, broken clip
- Serviceâ consideration: confirm clearance to âspray arm and rack geometry beforeâ final assembly
| Item | Description |
|---|---|
| Material | Stainless steel core with PVC/nylon dip⢠or moldedâ glass-filled nylon |
| Mounting | Snap-fit clips, riveted postsor keyed⤠sockets depending on rack model |
| Typical âclearance | Maintain approximately 10-15 mm between⤠tine extremities and rotating spray arms to avoid interference |
| Common impact | Bent or missing⣠tines â˘can redirect⣠spray, block detergent flowand âallow items to contact âspray arms |
Inside the appliance the tine geometry âŁdetermines how racks present dishes to directed spray;⣠tightly clustered or misaligned tines increase shadowing and⣠can cause the lower⤠spray âarmâ to stall or be struck âŁduring rotation. Inspect tineâ alignment with a simple ârotation⢠test: rotate the spray arm by hand and⢠confirm no contact across â¤the full rack pathand â˘verify fold-down tines fully latch to create âthe intended clearanceâ for tall items. When replacing a defective tine, ensure the replacement matches the original mounting âstyle and coating thickness-aftermarket parts with thicker â¤coating or slightly different bend⤠radii can â˘reduce clearance and alter spray patterns. for field repairs, removing⤠the affected rack to access âand replace a â¤modular tine or clip assembly âis typically fasterâ and reduces the risk of damaging adjacent spray-arm components.
Common Failure Symptoms, Wear Patternsand âDiagnostic Indicators for Tineâ Breakage or Corrosion
The W10728160 âŁWhirlpool⢠Tines âperform â˘the mechanical function of âlocating and retaining plates, bowls and glassware in the rack; they are typically epoxy-coated steel orâ stainless steel⤠posts that âtransferâ load into the rack frame. Common failure mechanisms are mechanical fatigue at the bend or anchor, â¤breach of theâ protective coating that exposes substrate⤠metal â˘toâ electrolytic attackand brittle fractureâ from repeated impact against hard objects. Compatibility during replacement matters: using a tine âassembly with the wrong anchor style or coating⣠changes the load âpath and corrosion resistance, â˘accelerating wear – âsuch as, aâ push-fit replacement on a rack designed⣠for welded tines willâ concentrate stress at the âretainer and can cause early shearing or â¤loosening.
Diagnosing tine breakageâ or corrosion relies on both visual inspection and simple mechanical âtests.Look for bending or permanent set under load, concentrated pitting at welds, flaking or blistering of the⣠coatingand transfer stains on dishes; âŁa flex test â (apply lateral force and observe for permanent deformation) helps differentiate elastic deflection from plastic deformation or cracking. Isolated broken tips usually indicate impact or overload, whereas uniform coating loss or widespread pitting âpoints to⢠chemical attack⣠from aggressive detergents or salt; â¤multiple adjacent failures often indicate â˘rack-frame distortion rather than individual tine defects,â and replacement decisions should consider anchor type and visible corrosion depth before installing aâ W10728160 replacement.
- Broken or sheared tine âtips – often impact orâ overload
- Bent tines with âŁpermanent⢠set â-â fatigue or overloading
- Coating blisters,⢠flakingor exposed metal – precursor to corrosion
- Rust or dark âstreaks on glassware – active corrosion transfer
- loose or detached anchors at the rail – retention failure
| Item | Description |
|---|---|
| Broken tip | Localized impact, material fatigue,⤠or shear at retainer; inspect â¤for nearby âforeign-object âdamage |
| Coating âfailure | Abrasion or⣠chemical âŁattackâ that â˘exposes substrate; leads toâ pitting and accelerated cracking |
| Permanent bend | Repeated âoverloading or rack distortion causing plastic deformation and⤠misalignment |
| multiple adjacent failures | Rack frame stress or corrosive habitat affecting an area rather âŁthan isolated posts |
Compatibility, Replacement Considerationsand Installation Procedures for W10728160 and Equivalent Models
W10728160 Whirlpool Tines are molded⤠prong assemblies that provide lateral support and separation for dishes on â˘the âupper âŁand lower racks; they transfer point loads into the ârack frame and must âŁmatch the ârack’s mounting geometry to functionâ correctly. Compatibility âdepends on several measurable attributes: stem â˘diameter and length, clip or stake style (snap-in clip, heat-staked bossor riveted âpost), number and spacing âof prongsand the nylon/glassâfilled material formulation that resists heat and detergent chemicals.Technicians should verify these attributes against the appliance model number and any OEM â¤cross-reference before substituting an equivalent, because an incorrect⣠stem size or clip type can fracture âthe rack boss, alter rack alignmentor⣠allow dishes to contact the⢠spray â¤arm during operation.
- Verify physical dimensions: stem diameter, exposed âstem lengthand prong⤠spacing.
- Confirm mounting method: removable clip âvs. heat-staked vs.riveted boss.
- Use proper tools: flat blade or pick to release clips,â needle-nose pliers for extractionand replacement clips if ârequired.
- If multiple bosses are âdamaged, consider full-rack replacement instead of â˘individual tines.
| Item | description |
|---|---|
| Reference checks | Measure stem and clip type; compare⤠to OEM⢠drawing or part cross-reference before installing an⣠equivalent. |
Replacement procedure begins with removing â˘the rack to gain âaccess⢠and inspecting adjacent mounting bosses for cracking or⣠deformation. Toâ remove aâ damaged tine,⢠pry out the âretaining clip or cut a heat stake, extract the â˘brokenâ stemand clean the mounting hole; seat â¤the new tine straight into â˘the hole⣠until the âclip â¤or stake secures it flush withâ the rack. After installation, load the rack with a representative set â˘of dishes and run a shortâ rinse-only âŁcycle to ensure tines maintain alignment andâ do not allow dishware to contact moving components. If the rackâ boss is worn, cracked,⢠orâ the new tine cannot seat âsecurely, replacement of the entire rack is â¤a more reliable⣠repair than attempting adhesive or makeshift fixes,â which can⤠fail under â¤thermal cycling and detergent exposure.
Q&A
What isâ the W10728160 Whirlpoolâ tine?
The W10728160 â˘is âa replacement rack⣠tine used in Whirlpool (and âŁsome affiliated-brand)â dishwashers. It is indeed a steel wire support-usuallyâ vinyl-coated-that holds plates, bowls and âŁother items in the dishwasher rack. It replaces a âdamaged, bentâ or missing tine so âtheâ rack can properly support dishes again.
How can I⤠tell if the W10728160 âtine (or my rack tine) needs âŁto be replaced?
Replace a tine if it is broken, severely bent, missingor â¤has cracked or flaked vinyl coating that exposes bare metal.Symptoms include dishes tipping orâ falling during the cycle, visible rust on⤠the tineor pieces of coatingâ in the dishwasher. Minor bends can sometimesâ be reshaped,but exposed rusted metal should be replaced to avoid contaminatingâ dishes.
Is the W10728160 compatibleâ with my âWhirlpool dishwasherâ model?
Compatibility depends âon the specific dishwasher model and rack configuration. To confirm, check âyour dishwasher model ânumber (usually on the door jamb) and look up⣠the parts diagramâ on Whirlpool’s parts site or an authorizedâ parts reseller. Theâ site will show whether W10728160 (or an equivalent part number) is listed âŁforâ your model.
Can I â¤replace the W10728160 myself or âshould Iâ hire a technician?
Many owners can replace a tine themselves. Replacement is typically a rack-level⤠repair that requires no electrical work. âŁIf the tine is welded into the âŁrackâ or the repair requires specialized welding, a technician might potentially be needed. If you’re comfortableâ with basic hand tools and following instructions,DIYâ replacement is usually straightforward.
What tools and â¤materialsâ do â¤I need toâ replace the W10728160 tine?
common⣠tools⢠and materials: needle-nose⣠pliers,diagonal cutters,a flat screwdriver (for removing clips),replacement tine (W10728160),vinyl sleeve or heat-shrink coating (rack repair kit),heat gun or lighter (for heat-shrink),work gloves,and safety glasses.⣠A rack repair kit that includes â¤sleeves and clips simplifies the job.
how do⢠I install the W10728160 âtine – basic âstep-by-step?
General steps: 1) â˘remove the affected rack from the dishwasher. 2) Remove any remaining vinyl⤠sleeve or clips holding the old⣠tine; cut and remove the old âŁwire if necessary. 3) Fit the new tine into the same slots orâ clip points on the rack, âaligning it as â˘the original. 4) Secure with the original clips or the âhardware supplied with the âreplacement. 5) Apply a new vinyl â¤sleeve or heat-shrink over the tine to protect it fromâ rust and⢠to âŁmatch the ârack coating, using a âheat source as required. 6) Reinstall the rack and⢠run a â˘short cycle to verify items sit correctly. âŁFollow any instructions that come â¤with the⢠part for model-specific details.
Can⤠I⤠reuseâ the oldâ vinyl coating or should I use⣠new sleeves/coating?
