ADW73389915 FUNNEL ASSEMBLY OEM is a molded funnel-style component used to route liquids within an appliance; as an OEM replacement part it provides the shaped passage and mounting interfaces required to channel fluid between adjacent components. Typically manufactured from engineering-grade thermoplastic or similar material,the funnel assembly is an engineered flow-guidance element rather than an active mechanical or electrical device,and it is sized and shaped to mate with specific housings,seals,and fasteners in the appliance model for which it was designed.
Inside the appliance the funnel assembly directs and controls the flow of water or process fluids, providing a leak-resistant transition between spray arms, pumps, drains, dispensers and sensor locations. It interacts directly with sealing surfaces (gaskets and o-rings), hose connections and pump inlets or outlets, and its geometry affects flow rates, air entrainment and the ability of pumps to prime. Proper positioning and intact sealing are therefore important for preventing bypass flow, minimizing turbulence that can trigger false sensor readings, and maintaining expected wash or drain performance.
In the article that follows you will find a technical review of the ADW73389915 funnel assembly covering its intended function and common installation contexts, guidance on compatibility and how to verify part fitment for specific appliance models, typical failure symptoms to watch for (for example leaks, reduced flow, noise or loss of pump prime), practical troubleshooting checks to isolate funnel-related issues, and replacement considerations including inspection of mating seals, recommended installation sequence, and torque or clamp requirements to restore reliable operation. the content is written to support technicians, engineers and informed appliance owners in diagnosing and addressing problems related to this component.

Function and Role of the Funnel Assembly in Appliance Fluid Management
The ADW73389915 FUNNEL ASSEMBLY OEM is a molded fluid guide that directs liquid and detergent from the dispenser area toward the sump and pump while maintaining a sealed, predictable flow path.In operation the funnel’s geometry controls flow rates and prevents air pockets or siphoning that would or else interrupt metered delivery; its mating faces and hose interfaces align with the appliance’s inlet ports and mounting bosses to ensure proper seating and leak-free operation. Functionally, the funnel acts as a low-resistance conduit and a mechanical interface between the dispenser, inlet valve, and drain pump, so dimensional accuracy and intact sealing surfaces are critical for repeatable cycle performance.
- Primary roles: channeling fluids, preventing backflow/siphoning, and providing a sealed connection to pumps and hoses.
- Compatibility considerations: matching mounting tab locations, hose diameters, and clip types when replacing the part.
- Common failure symptoms: visible leakage at seams, detergent pooling, poor spray performance, or persistent residual water in the tub.
For service and diagnostics, verify the funnel’s orientation and engagement of sealing surfaces before reassembly; confirm that clamps and hose connections are seated without twists or kinks and that the part is free of cracks or thermally-induced warpage. A short verification run (fill and drain) or a colored dye test can reveal leaks or unintended siphoning. Replace the funnel if structural damage, crazing, or deformations are present, and cross-check the OEM part number and mounting dimensions to ensure compatibility with the appliance model.

How the ADW73389915 FUNNEL ASSEMBLY OEM Works Inside the appliance: Internal Flow Paths and Component Interfaces
The ADW73389915 FUNNEL ASSEMBLY OEM serves as the internal flow manifold that collects recirculated wash water from the pump and directs it into the spray-arm distribution passages while maintaining sealed interfaces to the sump and pump housing. It fastens to the pump volute and incorporates molded channels and a check-valve seat that guide high-velocity flow to the spray-arm feed and help prevent backflow into the pump. Because the funnel defines the hydraulic path and sealing planes, correct OEM fit and undamaged gasket surfaces are necesary for expected flow rates and pressure; an incorrect or damaged funnel alters spray patterns and can cause leaks or reduced cleaning performance on compatible dishwasher models.”
In normal operation the funnel’s geometry and mating interfaces control pressure drops and prevent siphoning or sump overflow; failures manifest as symptoms such as weak spray, cavitation noise at the pump, or water accumulation in the lower tub.Practical inspection and service steps include checking for cracked mounting bosses, verifying the condition of the check-valve seat and gaskets, and clearing any debris from internal passages that can restrict flow. Typical interfaces and features to verify during diagnosis are listed below.
- Pump outlet mating surface – ensures concentric flow into the funnel.
- Check-valve seat – prevents reverse flow into the pump.
- Gasket and mounting bosses - maintain a watertight seal to the sump.
- Spray-arm feed channel – directs flow to one or more distribution ports.
- Float/sensor clearance – ensures proper operation of overflow detection.

Common Failure Symptoms and Diagnostic Indicators of Funnel Assembly Malfunction
The ADW73389915 FUNNEL ASSEMBLY OEM is a molded component that directs wash and drain flows between the lower spray assembly, sump and drain path; its geometry controls hydraulic paths and helps maintain proper sealing against the tub and sump interface. When the funnel’s internal passage becomes occluded, warped or cracked, water routing is altered which can produce reduced wash performance, standing water in the sump, or external leakage at the door seal. As an OEM replacement, the part is intended to replicate original mounting points and flow characteristics, so compatibility should be confirmed against the appliance model number and mounting features rather than by visual similarity alone.
- Reduced cleaning or visible residue on dishes – indicates hydraulic restriction or diverted spray caused by partial blockage or deformation.
- Standing water or slow drainage in the tub – suggests internal occlusion, misaligned drain path, or broken mounting tabs preventing a proper seal.
- Water on the floor or along the door edge – typically from cracks or compromised sealing surfaces on the funnel allowing bypass under pressure.
- Unusual gurgling or intermittent flow noises – can result from trapped air pockets forming against a distorted funnel profile.
Diagnostic checks begin with a detailed visual inspection for hairline cracks, melted/deformed plastic, and secure engagement of mounting tabs. Technicians commonly perform a dye or food-colorant test while running a short drain cycle to trace unintended leak paths, and they may remove the funnel to check for accumulated debris in the throat and ensure the mating faces are flat and undamaged.Because the funnel is a passive hydraulic part, measurement of unrestricted cross-sectional area (by inspection) and verifying correct seating with the sump and spray manifold provide the most reliable indicators that replacement is necessary; repair attempts are rarely effective when the molding is cracked or permanently deformed.
| Item | Description |
|---|---|
| Clogging/residue | reduced internal flow causing poor rinse and food retention in the sump |
| Cracks/Fractures | Direct leakage and loss of seal under pressure |
| Deformation/Melt | Misalignment with mounting points and altered hydraulic profile |
| Broken Tabs | improper seating that creates bypass or vibration-related noise |
Compatibility, Replacement considerations, and installation Procedures for Service Technicians
The ADW73389915 FUNNEL ASSEMBLY OEM is a molded funnel component that directs sump and drain flow into the pump inlet while providing a debris segregation surface and a sealed interface to the washer tub. In operation this part maintains hydraulic routing and pressure characteristics required for consistent pump priming; its internal geometry and sealing faces must match the pump housing tolerance to avoid cavitation, leakage, or reduced wash performance. The assembly is commonly injection-molded polypropylene with integrated snap tabs and mating flanges; compatibility across models depends on the pump/funnel mounting pattern and seal diameter, so confirm the OEM part number against the appliance parts catalog before assuming interchangeability.
for replacement, remove electrical power and shut off the water supply, then access the sump area by removing the lower access panel or tub cover. Inspect the mating surfaces for cracked plastic, worn gaskets, or clogged inlet screens and replace any EPDM seals or O-rings concurrently to ensure a leak-free interface. During installation align the funnel’s locating pins and engage the snap tabs until fully seated; secure any retaining screws to the specified hand-tight torque and verify that the pump impeller clears the funnel lip without rubbing. After reassembly run a short diagnostic or rinse cycle while observing for leaks and correct pump suction; if symptoms persist (noisy pump, persistent pooling) re-check seal seating and confirm pump-to-funnel concentricity.
- Verify part number and seal diameter before ordering.
- Inspect and replace seals/gaskets when installing a new funnel.
- Align locating pins and engage snap tabs fully to avoid misalignment.
- Perform a leak and functional test after reassembly.
