5303931779 Frigidaire Fill Hose Washers (PKG 100) are elastomeric sealing washers supplied in bulk for use at⢠water inlet and fill-hose connections on household appliances; they function⤠as compression seals between hose fittings and⢠inlet valves or appliance bodies to prevent leaks and âmaintain hydraulic integrity. â˘These washers are typically molded from rubber or similar â¤elastomers and are sized toâ sit in the⣠hose-ferrule or threaded coupling where they form âa gasket under compression.
Inside an appliance the fill hose â˘washer sits at the interface between the âexternal water supply hose and the appliance’s inlet valve â˘or fill port, interacting directly â˘with the valve seat, âhose ferrule, âand threaded coupling.⤠Proper sealing at this interface is critical⣠to maintain correct fill⤠rates, prevent external water⣠leakage that can damage components or cabinetry, âandâ preserve system pressure and flow characteristics that downstream controls and sensors relyâ on.
This article âwill explain the washer’s functional design âŁand material considerations, outline compatibility â˘and sizing checks a technician âŁshould perform, identify common failure⢠modes and âsymptoms such as dripping at the âinlet, intermittent fillingor visible deteriorationand provide practical troubleshooting and replacement guidance including inspection steps, selection âŁcriteriaâ (material hardness, inner/outer diameter, thickness)and installation considerations to ensure a reliable seal⤠without over-torquing fittings. The bulkâ package format (PKG 100)â and its implications for service stocking and â˘inventory management will also be discussed for technicians and service engineers. â¤

function and âRole of the Fill Hoseâ Washer in âŁWater inlet Sealing and Pressure Regulation
5303931779 Frigidaire Fill Hose Washers (PKG â100) areâ elastomeric sealing gaskets sized to sit between a fill hose fitting â¤and the appliance inlet or valve â¤body,⢠providing â¤the primary hydraulic seal at the hose-to-inlet interface. Properly compressed, the âŁwasher âprevents leakage â¤under the static and dynamic pressures encountered during fill cycles and helps maintain consistentâ inlet pressure by eliminating micro-pathways⤠forâ flow around⢠the hose fitting. The washer also âserves to center the hose end on the inlet seat and to absorb minor surface irregularities on the mating metal or plastic fittings; compatibility with a given Frigidaire model or third-party inletâ fitting depends on matching inner diameter, outer diameter, âand thickness⢠to â˘the valve geometry âŁrather than on brand alone.
The performance of these washers isâ governed by material âŁproperties (elastic modulus, compressionâ set, chemical resistance) andâ installation practice. Over time âor exposure to chlorinated water and temperature cycling,⣠the elastomer can harden, crackor take a permanent compression set, producing symptomsâ such as steady drips atâ the inletâ connection, intermittent pressureâ loss âduring fillingor flooding when hose clamps lose preload.For reliable field repairs, replace âŁdegraded washersâ with identical size and material types, seat âtheâ washer flat against the inlet faceand tighten âfittings only to the torque⣠needed to compress the washer without âextruding or cutting âit;⣠excessive torque accelerates failure. Practical âtroubleshooting examples include swapping the washer during a noisy âintermittent fill (to eliminate a⤠partial seal) or duringâ routine hose replacement to ârestore a watertight joint.
- Installation⤠tips:â seat washer flat, verify ID/OD match, avoid over-tightening, inspect for hardness or cracks.
- Failure symptoms: âcontinuous âŁdrip at â¤inlet,⣠intermittent fill cycles, visible deformationâ or extrusion.

How the 5303931779 Frigidaire Fill Hose Washers (PKGâ 100)â Works Inside the Appliance
5303931779 Frigidaire fill Hose Washers (PKG 100) are small elastomeric gaskets installed at the hose-to-inlet coupling on Frigidaire washing machines.They compress between âthe â¤threaded â¤fill hose nut and âthe inlet valve spud to form a fluid-tight seal, compensate â˘for minor misalignment or machining tolerancesand prevent⣠metal-on-metal contact that accelerates wear. Installed⤠correctly, these washers maintain sealing geometry under normal household water pressures and allow⢠for repeated hose servicing without⢠immediate leakage.
The washers are exposed to cyclic temperature changes, detergent chemistry, âand mineral deposits; â¤common failure âmodes include âŁcompressionâ set â(permanent flattening), hardening, surface crackingand tearing at the bore. Technicians should inspect washers whenever hoses are⤠removed and âreplace them âŁif the profile is flattened or cracks areâ visible, as âa new washer restores the intended sealing interface more reliably than reusing âa deformed â¤seal. âFor practical compatibility,match the washer inner diameter âŁand thickness to the original or measure the inlet seat andâ hose coupling âŁdimensions before installation.
- Signsâ a washer needsâ replacement: visible cracks, flattened cross-sectionor persistentâ drippingâ at the hose connection.
- Typical service action: remove the hose, inspect and clean the seat, fit a replacement washer,⤠and hand-tighten the âcoupling then finalize with a⢠quarter-turn to recommended torqueâ to avoid âover-compression.
| Item | Description |
|---|---|
| Function | Seals the hose coupling⢠to the inlet valve to⢠prevent leakage and reduce metal wear |
| material | Elastomeric sealing compound (rubber/EPDM-class materials commonly used âfor durability) |
| Failure indicators | Drips at connection, flattened or cracked washer, persistent leaks after tightening |
Common Failure Symptoms and Diagnostic Tests for Leaks, Flow Restrictionand Pressure Loss
The small elastomeric seals sold as â5303931779 Frigidaire Fill Hoseâ Washers (PKGâ 100) â¤function as the primary â˘static sealâ between a household water supply⢠hose and the washing machine inlet valve or spigot. These washers are typically⢠molded âfrom neoprene or EPDM and rely on controlled compression and correct flange geometry to maintain a water-tight joint under normal domestic inlet pressures. Over â˘time the material can harden, crack, flattenorâ develop surface âŁnicks â˘thatâ compromise the seal;â compatibility is steadfast by outer â˘diameter, inner boreand the retaining⤠lip profile, so matching â˘the washer geometry to the Frigidaire inlet fitting is essential during service⢠or hose⤠replacement.
Common âŁfailure symptoms include externalâ leakage at â¤the hose connection, intermittent slow fill cycles, audible whistling or sputteringâ during filland reduced inlet pressure â˘that can cause incomplete cycles. Diagnostic tests that produce actionable âresults are visual⢠and âtactile inspection under aâ luminous âlight, âa soap-solution leak test around the hose bead, isolating theâ appliance and measuring fill time for a known volume to detect flow restrictionand using an inline pressure gauge at the inlet to confirm supply pressure at the valve. When a leak or⢠pressure loss is confirmed,remove the hose and inspect the washer seating surface and valve seat for debris or corrosion; replacing the washer and retesting â¤the â¤connection âoften resolves seal-related failures,while âpersistent flowâ restriction after washer replacement indicates a clogged valveâ or âdamaged inlet assembly requiring further service.
- Visible drip âor pooled water at theâ hose connection
- Slow or inconsistent fill rate; long fill times
- Audible whine/whistle during fill or⣠air sputtering
- Normal supply pressure at theâ spigot but low⤠pressure at the inlet (indicates internal restriction)
| Item | Description |
|---|---|
| Visual inspection | Check â¤washer for cracking, flattening, deformationor embedded debris â¤at the sealing face. |
| Soap-solution leak test | Apply soapy waterâ around the âhose bead⢠while pressurized; bubbles âindicate an externalâ seal âleak. |
| Flow measurement | Measure fill timeâ for a fixed container⤠with the washer installed vs.removed âto identify⢠restriction caused by seating or material intrusion. |
| Pressure â˘test | Use an inline âgauge at the appliance inlet to compare âsupply âpressure to inlet pressure and detect pressure loss across the connection or valve. |
| Compatibility check | Verify outer/inner diameter and⢠lip profile against the appliance inlet; improper fit can mimic washer failure symptoms. |
Compatibility, Replacement Considerationsand Step-by-Step Installation Procedures
5303931779 Frigidaire Fill Hose âWashersâ (PKG 100) are elastomeric sealing rings designed to⣠create a⤠leak-tight compression seal between⣠fill-hose couplings and appliance inlet fittings. â˘Functionally they are⣠specified by inner diameter (ID), outer diameter (OD) and cross-section thicknessand material selection (common elastomers:â NBR or EPDM) governs resistance to hot â¤water, detergentsand âchlorinated municipal water. When assessing âŁcompatibility, match ID to the hoseâ tailpiece, âOD toâ the inlet boss seating diameterand material⣠to the operating temperature and chemical exposure expectedâ in the appliance; identical appearance is â˘not sufficient because a small mismatch in â¤thickness or hardnessâ will produce âleaks orâ premature extrusion. Technicians frequently replace these washers during â˘hose swaps, inlet â¤valve serviceor routine maintenance âŁon Frigidaire washing â˘machines and otherâ makes that shareâ similar connector geometries, so buying â¤bulk packs simplifies field service⤠but⤠always verify the specific model’s fitting geometry beforeâ installation.
Replacement and installation⢠are âŁsimple but require a âfew practical checksâ to avoid rework: shut off â˘the â˘water supply and relieve system pressure, inspect âboth the hose end â˘and valve seat for corrosion, debris, âor burrsand remove any old, hardened washers that can prevent proper sealing. âŁHand-install the new washerâ so it seats flat against theâ mating surface (verify orientation if âthe washer has a⢠beveled face),reconnect the hose and tighten until snug-avoid âŁexcessive torque âon plastic threads to prevent deformation.⢠After restoring the âwater supply,â perform a pressure test at normal operating pressure and monitor for slow leaks; if a small leak persists, re-seat âthe washer and âcheck âfor microscopic damageâ or incompatible âŁmaterial that may require an option elastomer.
- Turn off theâ water and relieve⣠pressure before disconnecting âhoses.
- Inspect â˘mating surfaces for damage and clean debris or mineral deposits.
- Replace washer, ensuring correct â¤ID/OD fit and orientation, then hand-tighten hose and⢠finish with aâ controlled snug torque.
- Restore water, observe for⤠leaksand retighten onceâ ifâ necessary;â replaceâ again if⤠leakage continues.
