W10728160⤠Whirlpool Tines are⣠replacement rack⤠prongs â˘used in Whirlpool dishwashers toâ supportâ plates,bowls,and other dishes during the wash cycle. The component is a tine (prong) element of the dish rack assembly, typically formed of metal and often coated for corrosion resistance and to protect glassware; it is supplied as an OEM part under the referenced number for direct fit âŁto compatible⤠rack configurations.
Inside the appliance the tine functions as â˘a mechanical support and positioning feature that determines how âitems⢠are oriented to the spray pattern and water jets; correct positioning helpsâ ensure proper water exposure, drainage and drying. The tine interfaces mechanically âŁwith the ârack frame and adjacent⤠tinesand indirectly affects hydraulic and thermalâ subsystems (spray arms, sump flow and heating/dryingâ cycles) by influencing⣠how dishes obstruct or expose critical â¤flow paths. A compromised â¤tine-broken, bentâ or withâ degraded coating-can allow items to â¤shift, block spray, create⢠contact points that âchip or scratchand accelerate localized corrosion that may spread to the ârack structure.
In this article you âŁwill find a technical overview of the W10728160 tine including it’s intended function and typical rack placements, guidance on âcompatibility âchecks with specific Whirlpool model families, common failure âsymptoms to look for (physical damage, exposed metal, dish instability, wash-performance issues), stepâbyâstepâ troubleshooting and inspection techniquesand practical replacement considerations such as attachment⣠method, material/coating differences, required tools and safety precautions. The facts is presented toâ help a technician, engineer or appliance owner diagnose tine-related issues and choose an appropriateâ repair or replacement approach while avoiding unnecessary parts swaps.

Function andâ LoadâBearing Role of Dishwasher Rack Tines
W10728160 Whirlpool⤠Tines are the individual posts on âa dishwasher rack that⤠locate and support dishes while transferring loads into the rack frame. Constructed âas âcoatedâ steel wire or molded polymer posts depending âon the rack design, these tines maintain⣠consistent spacing and orientation of plates, bowls and cookware, resistâ lateral deflection â¤from spray dynamicsand limit contact between items to prevent chipping. Replacement parts that match the originalâ mounting âclip,â tine pitch and folding geometry restore the⢠intended â˘mechanical behavior; verify clip type and spacing on the existing rack before installing a replacement.
- Load control: each⤠tine directs âvertical and lateral forces into the frame;⣠distribute⢠heavy items across multiple tines rather than loading a â¤single tine.
- Compatibility: mounting style (press-in clip,â welded base, folding hinge) determines interchangeability between models.
- Durability indicators: worn coating, bent wiresor loose mounts reduce stiffness and increase⣠risk of damage during cycles.
- Serviceability: tines are frequently â¤enough â˘replaceable â˘individually or in strips-match pitch and clip style⢠forâ reliable fit.
For practical use,place plates and flatware soâ thatâ weightâ is shared by adjacent tines and avoid cantilevering heavy cookware â˘on aâ single post; stemware and delicate items benefit from âbeing secured between two tines to limit vibration. Technicians inspecting a rack should check for⣠coatingâ abrasion, corrosion atâ welds or â¤plastic fatigue âat folding hinges; broken or deformed tinesâ typically require replacement of the affected tine strip or the OEM-matching partâ to restore â˘original load transfer characteristics.

How the W10728160 Whirlpool Tines âOperates within the Rack⤠Assembly and Water â˘Spray environment
The W10728160 Whirlpool Tines serve as the molded prong assemblies thatâ secure dishes within âŁthe dishwasher rack while minimizing obstruction to the spray pattern. These tines are designed to clip into theâ rack framework â¤with alignment⢠tabs and retainers that locate each prong in a fixed pitch so plates, âŁglasses,⢠and bowls present an unobstructed âface to âthe⣠rotatingâ spray⤠arms. Their geometry and spacing are chosen to balance mechanical support and âhydrodynamic⣠exposure: narrow, evenly spaced tines reduce surface area that can shadow water jets,â while the plastic coating on the âtines provides dielectric and corrosion resistance toâ avoidâ rust and reduce⣠noise âfrom dish contact. In practice, a cracked or missing segmentâ of the W10728160 Whirlpool Tines can allow items âto âtip and block the spray, producing localized cleaning failures or repeat cycles to remove trapped soils.
- Mounting:â clip-in âŁrack posts with keyed tabs for positive orientation
- Coating: vinyl/nylon overmold to resist âŁabrasion âŁand corrosion
- Function: positionâ items and â¤minimize spray shadowing
- Failure symptoms:â bent tines, coating loss, dish tipping, spray blockage
Within the spray environment the tines act âas passive flow obstructions whose size andâ placement influence local turbulence and impingement angles; technicians should verify that replaced tines restore⤠original pitch and are not rotated or âinverted, which can increase hydraulic shadowing. Compatibilityâ is mechanical rather than⢠electronic: matching the W10728160 part number â¤to the rack’s clip geometry ensures the proper spacing and retention force; replacement is typically a manual snap-out/snap-in operation without special tools. For troubleshooting, inspect âŁtine⤠coating integrity, measure lateral play at the base of the⢠tineand âŁobserve spray coverage during an âopen-cycle⤠test-areas downstream of âdamaged tines often â¤show poorer rinse performance and spot patterns⢠on âexposed dish surfaces.

Common Failure Symptoms,â Corrosion Indicatorsand Mechanical Wear Patterns
The W10728160 Whirlpool Tines act â¤as the load-bearing prongs thatâ position dishes âand preserve spray⣠clearance in dishwasher âracks; they must match the rack’s clip âgeometry and coating type for proper fit andâ to avoid âgalvanic⤠or mechanical incompatibility. Functionally these tines are normally steel⢠substrates with â¤an electroplated or⢠polymerâ coatingand common failure modes areâ mechanical deformation from repeated â˘loading, impactor⤠fatigue at the narrow base, plus localized corrosion where the protective coating is âcompromised. Chemical attack from alkaline detergents, abrasive⤠soilsor hard-water deposits accelerates coating breakdown and pitting, while⣠mechanical wear manifests as permanent bends, tip⣠flatteningor âweld âfailures that allow tines to shift under⤠load and reduce rackâ utility.
- bent or deformed prongs: permanent set or kinks that prevent proper item alignment and may interfere with rack movement.
- Coating flaking or blistering: loss âof protective layer exposing substrate â¤and enabling⢠rapid corrosion.
- Red-brown rust or⣠white powder:â surface corrosionâ or sacrificial coating breakdownâ concentrated at welds âand bends.
- Pitting and through-holes: localized material loss that reduces cross-section and strength.
- Cracks at⤠theâ base or âmounting point: fatigue fractures that lead to detachment⤠or unpredictable âfailure under cyclic loads.
Technicians âshould combine visual inspection with â¤tactile tests-probe for looseness, measure remaining diameter â¤with calipersand inspect⣠welds and the coating edge with magnification-to classify severity and decide whether repair (recoating or localized patch) or replacement is required. Minor surface staining⢠without substrate loss can sometimes â¤be neutralized and recoated,â but⣠pitting, âreduced cross-sectionor cracks at the base compromise structural integrity andâ require replacement to restore rack compatibility and prevent downstream damage⤠toâ the rack assembly or dishes.
| Item | description |
|---|---|
| Pitting | Localized corrosion removingâ metal and reducing load-bearing capacity. |
| Coating loss | Exposure of bare steel leading to accelerated rust and adhesive failure. |
| Base fracture | Fatigue or impact cracks at the mounting point that cause detachment. |
Compatibility, âŁReplacement Considerations, â¤Installation Procedureand⤠Diagnostic Troubleshooting â¤for ârack Tines
The W10728160 Whirlpool Tines are replacement prongâ assemblies designed to restore the dish-holding geometry of a dishwasher rack; they are normally a PVC- or nylon-coated steel wire form that â¤snaps âor⣠clips into the rack frame. These tinesâ support âplates and glassware, maintain spacing for spray coverage,â and resist flexing âunder load.Compatibility âdepends on⤠the rack’s mounting style – common interfaces are molded⢠posts with snap-fit clips, riveted sectionsorâ multi-tine removable modules – â¤so theâ W10728160 fits racksâ that use the same post pitch and clip geometry. Failure modes include coating abrasion that leads to rust staining, broken â¤or bent wires causing unstable loadsand âŁdamaged mounting posts or clips âthat allow tine⣠sections âŁto shift during⢠cycles; each failure affects how water reaches itemsâ and can create intermittent contact â¤with spray arms or wash patterns, which techniciansâ can verify â˘during inspection.
- Inspect⤠coating for chips and bare steel, check â¤for bent prongs or loose/missing clipsand ânote whether the tine section â˘is integral⣠orâ modular before ordering âŁreplacement.
- Removal typically requires⤠retracting the â˘rack, releasing end-stopsandâ detaching the clip or pry-out ârivets for modular sections; installation reverses that âŁprocess and demands full engagement of the mounting âtab until it audiblyâ snaps⢠into place.
- Troubleshoot byâ reproducing â¤the symptom with an empty ârack âto observe contact points and wash âcoverage; measure post spacing ifâ an âŁexact-fit replacement is required.
When replacing W10728160 âWhirlpool Tines, use minimal hand tools (flat pryer,⣠needle-nose pliersand â¤a trim pick) âandâ avoid deforming the surrounding rack rails; align the mounting posts â˘and push the tine â˘module straight âon to prevent shear loads onâ clips. If clips or posts are corroded, replaceâ the entire clip or the rack âsection rather than attempting a â¤spot ârepair, because partial fixes can introduce⢠misalignment and repeat âfailure. For diagnostic troubleshooting, verify thatâ a loose tine section is notâ interfering with the spray arm rotation, check for dish load patterns that â¤concentrate weight on â¤a single tineand confirm that replacement parts match⤠the rack’s hole pattern; if⣠replacement does not restore function, inspect the rack rail and stop âŁmechanisms forâ deformation and replace the rack assembly if â¤the mounting geometry is compromised.
| Item | Description |
|---|---|
| Material | Steel wire with PVC/nylonâ coating; provides rigidity and corrosion âresistance |
| Mount type | Snap-fit post, clip-on moduleor riveted section – must match rack âŁgeometry |
| Common failure mode | Coating abrasion, wire fracture, broken mounting cliporâ deformed rack post |
| Typicalâ repair action | Replace tine module W10728160⣠or the clip/rack section; ensure proper seating and alignment |
Q&A
What is part âW10728160?
W10728160 is an OEM âreplacement rack tine (the individual âspike) used on certain whirlpool appliance racks.It is indeed âaâ formed steel tine, normally with âa baked-on protective coating, âintended to replace brokenâ or missing spikes so⣠the⣠rack can support cookware âor dishes correctly.Confirm the âexact function for your appliance⣠by matching the part number to your model.
How can Iâ verify W10728160 is the correct replacementâ for my whirlpool rack?
Verify compatibility by checking your appliance model and serial number (usually on a tag inside the oven door frame or on the appliance). Compare the old tine⣠to theâ part image/specs on âthe Whirlpool parts website âŁor an â˘authorized âparts distributor. Alsoâ measure key dimensions (insertion stem length, â¤overall⣠exposed lengthand stem â¤diameter) and compare mounting style (clip-in vs. welded) to ensure a match.
Can I âinstall⢠W10728160 myselfand what⤠tools do âI need?
Yes,â if your⣠rack uses clip-in tines, youâ can usually install itâ yourself. Tools: flat-head⢠screwdriver or â˘trim tool, needle-nose pliersand gloves. Procedure: remove the rack, release any retainer clip or tab holding the tine, slide out the damaged tine from the rack channel, insert âthe replacement tine so its â˘stem seats into⣠the â˘channeland âre-engage the retainer. If the tineâ is welded to the rack,⣠DIY âreplacement is not â˘practical and the rack âŁor a professional repair is required.
What should I do⢠if the replacement tine does not stay secure â¤in the rack?
First check thatâ the rack’s retainer clip âor tab is intact and â˘properly positioned-often the clip is⣠a separate piece that wears or breaks. If the clip â˘is missing or bent, replace⣠it. Inspect the rackâ channel for deformation or stripped mounting slots; if they are damaged the âtine won’t lock and the â¤rack âŁor channel⢠may needâ replacement. Asâ a temporary measure only, a high-temperature-rated fastener or appliance-safe adhesive⣠can âbe used, but replacing damaged âhardware is theâ proper fix.
Is the W10728160 âcoating resistant to oven temperatures and oven â¤cleaners?
The tine is typically made from steel with a baked-on enamel or epoxy coating designed to tolerate âŁnormal oven temperatures â¤and resist corrosion. Avoid harshâ abrasive cleaners or⣠concentrated oven cleaner on coated surfaces as they can damage â¤the finish. For cleaning, use âwarm soapy water and non-abrasive pads; for baked-on âŁsoils, follow the appliance manufacturer’s recommended cleaning methods.
How do Iâ measure⣠a âtine to be sure I order the rightâ one?
Measure these dimensions: overall exposed length (from front of rack to tip), insertion stem length (the⤠portion that fits into the rack channel), stem diameter or cross-section sizeand the spacing/shape of any mounting notch or tab. Also note whether the tine âis straight orâ bent âand the number of mounting positions.Record these andâ compare to âthe⢠part listing or âsend â˘photos to⤠a⤠partsâ supplier⤠for confirmation.
Is it better to replace individual tinesâ or the entire rack?
Replace âindividual tines if they are clip-in and the ârack channel and⤠retainers are intact-this is economical and straightforward. If multiple tines are damaged, the⢠mounting clips â¤are brokenor the rack channel is⣠bent/worn, replacing the⣠entire rack is often more reliable⢠and âdurable. âWelding⤠a tine â¤is possible but not recommended for most homeowners due to heat damage risk to the coatingâ and dimensional changes.
Where can⢠I buy W10728160 and â˘are aftermarketâ parts acceptable?
You⣠canâ buy W10728160 from whirlpool’s official parts website, authorized dealersandâ reputable online appliance-part retailers. OEM parts ensure correct fit and coating specification. Some aftermarket tines may be cheaper but can differ in âdimensions, coating qualityand heat resistance-compare specifications and â¤return policies before purchasing.⣠Keep your appliance model number handy when⤠ordering to avoid mistakes.
