Whirlpool Dishwasher Pump to Sump Hose Assembly Parts — Models & Compatibility

The pump to sump hose assembly is what carries water from your dishwasher's sump (the lowest point where water collects) to the drain pump. When this hose cracks, splits, or the clamps fail, you'll see water pooling under your Whirlpool dishwasher after cycles. Part W10195114 replaces the original equipment hose and fits most Whirlpool, KitchenAid, Maytag, Amana, and Kenmore-branded dishwashers from the WDF and WDT series.

Is This the Right Part for Your Model?

Check your dishwasher's model number—it's usually on a sticker inside the door frame along the top or side edge. This hose assembly fits WDF110, WDF310, WDF510, WDF520, WDF530, WDT710, WDT750, WDT770, WDT790 series, plus corresponding Amana ADB models and KitchenAid KDFE, KDTE, KUDS, and KUDE series. If your model number starts with any of these prefixes, you're likely in the right place.

About This Replacement Part

This isn't just a generic rubber hose—it's a molded assembly that connects precisely between your sump housing and drain pump inlet. The OEM part number W10195114 supersedes older numbers like W10445975, AP5618621, PS3651318, and 2312026, which means if you've got any of those listed in your service manual, this is your current replacement. The hose is designed to handle the pressure and temperature swings of normal wash cycles, but over time (usually 8-12 years), the rubber degrades where it bends most, right near the clamp points.

Why This Hose Fails

Dishwasher hoses don't fail overnight. You'll typically see a slow progression: first, the rubber gets stiff and loses flexibility. Then tiny stress cracks form where the hose curves. Eventually, during a wash cycle when water pressure peaks, those cracks open up and water starts leaking onto your floor. Sometimes it's the spring clamps that lose tension over years of heat cycling—they just don't grip as tight anymore, and water seeps past them. Either way, the fix is replacing the entire hose assembly, clamps included.

Compatible Whirlpool & Related Brand Models

This hose assembly works across multiple brands because Whirlpool Corporation manufactures dishwashers under several names. Here's what fits:

• Whirlpool WDF Series: WDF110PABB4, WDF310PAAB0, WDF510PAYB0, WDF520PADM0, WDF530PSYM0
• Whirlpool WDT Series: WDT710PAYM2, WDT750SAHZ0, WDT770PAYM1, WDT790SAYM2
• KitchenAid KDFE/KDTE: KDFE104HPS0, KDTE104ESS0, KDTE204EPA0, KDTE334GPS0
• KitchenAid KUDS/KUDE: KUDS30IXSS6, KUDE40FXSS5, KUDE48FXSS3, KUDE60HXSS4
• Amana ADB Series: ADB1100AWB0, ADB1100AWW0, ADB1400PYB0, ADB1400PYS0
• Maytag MDB Series: MDB4949SDM0, MDB7949SDM0, MDB8959SFZ0
• Kenmore Elite: 66513153K110, 66513159K110, 66513163K110

This list covers the most common models, but the part fits many more variations within these series.

Installation Considerations

Replacing this hose requires pulling out your dishwasher to access the underside. You'll need to disconnect the kick plate, tip the unit back slightly, and work from underneath. The old hose is held by spring clamps at both ends—squeeze them with pliers to slide them off. The new assembly comes with fresh clamps already positioned, so you just slide the hose onto both fittings (sump outlet and pump inlet) and secure the clamps. Make sure both ends are seated fully before running a test cycle, because a partially-seated hose will leak immediately.

What Comes in the Box

The W10195114 assembly includes the pre-formed rubber hose with both spring clamps already attached. You don't need to buy clamps separately—they're part of the assembly. The hose length and bends are molded to fit the specific routing between your sump and pump, so there's no cutting or adjusting needed.

Cross-Reference Numbers

If you're looking up parts by different numbering systems, this same hose goes by several identifiers depending on where you're searching:

• W10195114 (current Whirlpool number)
• W10445975 (previous version)
• AP5618621 (AppliancePartsPros number)
• PS3651318 (PartSelect number)
• 2312026 (legacy part number)

All of these reference the exact same part—manufacturers just update part numbers periodically as they refine production.
