3385556 Whirlpool Drain Hose is a specific replacement discharge hose used to convey wastewater away from a household appliance.It is indeed a flexible molded hose assembly that provides a sealed path from the appliance’s internal drain pump or tub outlet to the home’s drain connection; the assembly typically incorporates hose material and molded fittings designed to mate with the appliance’s outlet and standard household plumbing connections.
Within the appliance, the drain hose forms the final stage of the hydraulic discharge system and directly interfaces with the drain pump, tub outlet, and external plumbing (standpipe, trap, or garbage disposal). its proper function depends on correct routing, secure fittings/clamps, and compatibility with the pump outlet and external drain hardware; failures or restrictions in the hose affect flow rate, create backpressure or siphoning conditions, and can generate leaks, vibration transmission, or diagnostic fault codes triggered by slow or incomplete drain cycles.
This article will explain the 3385556 drain hose’s intended function and physical characteristics, describe how to verify model compatibility and connector types, identify common failure symptoms (such as leaks, kinks, blockages, odors, and slow draining), and outline diagnostic checkpoints and replacement considerations technicians, engineers, and appliance owners should use when evaluating or replacing the part – including selection criteria for length, inner diameter, fitting style, clamp and routing requirements, and factors that impact long-term reliability.

Function and Role of the Drain Hose Assembly in Whirlpool Laundry Appliances
The 3385556 Whirlpool Drain Hose is the replaceable flexible conduit that carries discharge from the washer pump to the household drain, standpipe, or utility sink. Functionally it must form a leak-tight connection at the pump outlet and at the drain termination, transmit the intermittent high-flow pulses produced by the washer pump, and be routed to prevent siphoning and backflow by maintaining a proper high loop or meeting local air-gap requirements. The hose material and internal diameter determine flow characteristics and resistance to heat and detergent chemistries, so matching the hose to the pump outlet size and service conditions preserves drainage performance and reduces the risk of leaks or blockages.
The hose behaves as a dynamic pressure conduit: during the drain cycle it sees rapid flow surges and occasional backpressure, and over time wear typically appears at bends, clamp interfaces, and abrasion points. Compatibility is measured by outlet geometry,clamp style,and usable length-replacement must match these to ensure a secure fit and correct routing. For practical service, inspect for cracks, softening, kinks, or internal obstructions and confirm the hose achieves a high loop or air-gap above the machine cabinet to prevent wastewater re-entry; use corrosion-resistant clamps and trim only the minimum required length to avoid tension. Common troubleshooting signs that point to a failing drain hose include slow drainage,gurgling noises,visible leaks at the clamp,and water remaining in the tub after the cycle ends.

How the 3385556 Whirlpool Drain Hose Integrates with the Pump and Internal Water-Flow Systems
The 3385556 Whirlpool Drain Hose serves as the mechanical and hydraulic link between the appliance’s discharge pump and the household drain. It mates directly to the pump outlet-typically on a barbed or speedy‑connect fitting-and must present a continuous bore and compatible diameter to avoid flow restriction and excessive backpressure. Bends, corrugations and unsupported spans increase head loss and can create air pockets that change pump loading and reduce effective flow; conversely, a smooth, properly sized run minimizes turbulence and helps the pump operate within its designed performance envelope. The hose material and inner profile also affect abrasion and clog susceptibility: a flexible reinforced polymer resists burst and chemical attack but corrugated sections can trap lint or debris produced by internal water‑flow systems.
For practical installation and troubleshooting, match the replacement hose to the original pump interface and preserve the same routing geometry so the pump sees the expected hydraulic conditions. Common checks include confirming a secure clamp at the pump outlet, maintaining a gradual slope to the drain to prevent pooling, avoiding tight radii that pinch the ID, and providing mechanical support to prevent strain on the pump connection. Examples: when replacing 3385556 Whirlpool Drain hose on a front‑load washer, verify the barbed fitting size and perform a drain test cycle to confirm consistent discharge; when diagnosing intermittent drainage, inspect for kinks, internal collapse, or debris traps at corrugations.The following checklist summarizes key installation and service points:
- Verify clamp type and torque at pump and drain connections.
- Maintain continuous slope and avoid low spots that collect water.
- Replace with matching ID/OD and a compatible material rating for temperature and detergent exposure.
- Run a full drain cycle after installation to confirm unobstructed flow and absence of leaks.

Common failure Symptoms and Diagnostic Procedures for Blockages, Leaks, and Kinks in the Drain Hose
The 3385556 Whirlpool Drain Hose functions as the flexible discharge conduit that carries pump effluent from the appliance to the household drain or disposer. Typical construction is reinforced thermoplastic or rubber with ribbed fittings and a specified inner diameter to match the pump outlet; compatibility requires matching the connector style, length, and internal bore to avoid backpressure or siphoning. Failure modes manifest predictably: internal debris accumulation or foreign objects reduce flow and cause slow draining or standing water, radial cracks or abrasions produce visible leaks under pressure, and sharp bends or compression from routing lead to kinks that restrict flow. Recognizing the component behavior-how it responds to pump suction, how clamps seal at junctions, and how material flexibility changes with temperature-helps isolate whether the hose, the pump, or the household trap is the root cause.
- Slow or incomplete drain cycles (often partial blockage or collapse)
- Water pooling in the tub or at the base of the appliance (leak or blocked outlet)
- Intermittent draining or gurgling noises (kink, air lock, or partial obstruction)
- Visible wet spots, stains, or drips at hose connections (failed clamp or crack)
| Item | Description |
|---|---|
| Slow drain | Partial internal blockage, collapsed section, or undersized/incorrectly routed hose |
| Visible leak at connection | Lose or corroded clamp, incorrect fitting type, or hairline crack near barb |
| Intermittent flow | Kink in hose, debris temporarily lodged, or obstruction at disposal/discharge point |
Diagnostic procedure begins with a powered-off, depressurized inspection: visually trace the hose path for kinks, pinch points, and abrasion; check clamps and the hose-to-pump interface for correct seating and clamp torque. If the hose appears intact but performance is poor, remove and inspect the interior by passing water or a light source through the hose-resistance, turbulence, or trapped solids indicate blockage; a steady spray when the pump runs into an open container confirms pump output and isolates the hose as the issue. For leaks, perform a pressure check by running a short drain while observing all joints and seams; localized wetting at a joint usually means clamp replacement or reseating, whereas longitudinal leaks require hose replacement. Practical examples: a dishwasher that drains slowly only when heavy soil is present frequently enough has partial buildup in the hose or high point trap-cleaning the hose and verifying the correct routing eliminates the air pocket; a constant drip at the pump barb typically resolves by replacing the clamp and, if necessary, the hose section to restore a secure seal.
compatibility, Replacement Considerations and Step-by-Step Installation for the 3385556 Whirlpool Drain Hose
The 3385556 Whirlpool Drain Hose channels discharged water from the appliance pump to the household drain and must maintain an open, non-restrictive bore while resisting repeated flexing, abrasion and exposure to moderately hot wastewater. This part typically uses corrugated or reinforced tubing and attaches to the pump outlet with either a crimped barb, worm-gear clamp, or quick-disconnect elbow; verify the pump outlet diameter and connector style on the appliance before ordering a replacement as some Whirlpool models use a molded elbow or a different nominal diameter that require an adapter.common failure modes include compression at tight bends, abrasion at the clamped connections, and internal fouling that reduces flow or causes the pump to run longer than expected, which can trigger error codes or premature pump wear.
- Measure pump outlet inner diameter and overall hose length to confirm fit.
- Inspect connector type (barb, quick-connect elbow, or molded fitting) for adapter needs.
- Replace clamps and grommets with the hose to ensure a secure seal.
- Plan routing to avoid kinks and provide a anti-siphon loop above the trap outlet.
| item | Description |
|---|---|
| Inner diameter | Typically 7/8″-1″ (measure to confirm for adapters) |
| Material | Corrugated PVC or reinforced elastomer for flexibility and abrasion resistance |
| Common clamps | Worm-gear or spring clamps; crimped barbs on OEM assemblies |
| Installation note | Maintain an anti-siphon loop and avoid sharp bends within 6-8 inches of the pump outlet |
For replacement, disconnect power and pull the appliance forward to access the rear; loosen and remove the clamps at the pump discharge and at the sink or trap connection, then remove the hose while supporting any retained water to prevent spills. fit the new hose so the hose end fully engages the pump barb or quick-connect, secure with a properly sized clamp tightened to OEM torque recommendations, route the hose with a high point to form an anti-siphon loop (or use an air gap per local plumbing code), trim excess length only if the hose will not kink, and run a short drain cycle while inspecting all joints for leaks and confirming normal pump operation; if the appliance uses a molded elbow or different diameter, use a dedicated adapter or replace the elbow assembly rather than forcing a mismatched hose, and replace clamps and any deteriorated grommets simultaneously occurring.
