Quick answer
If a hose on a Kenmore 665.13963K017 dishwasher is cracked, chewed, split, or leaking, stop the dishwasher and do not run another cycle. From a dry, safe position, turn off the dishwasher's power and the under-sink water shutoff, then clean up standing water without pulling the built-in unit. A hose at the water-supply side can remain pressurized even when the dishwasher is idle; a drain hose usually leaks during draining or leaves water in the tub. Check only connections that are visible without removing panels or moving the appliance, and use the exact Kenmore model manual to identify the hose. Because this is a rental, document the damage and notify the landlord or property manager before arranging repair or approving a part. Do not select a replacement from a photo or generic Kenmore 665 match.

Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Stop the cycle, isolate power from a dry safe position, close the under-sink dishwasher water shutoff, and remove only accessible standing water from the floor.
Expected result: Water continues to flow while the dishwasher is idle, water is near electrical parts, or the leak stops after the shutoff is closed.
Next step: Keep the dishwasher disconnected and arrange qualified service through the landlord or property manager. Do not reopen the valve to reproduce the leak.
Stop if: Do not handle wet plugs, wiring, or controls, repeatedly reset a breaker, or run another cycle.
Why this matters
Why: A continuing supply-side leak or water near electrics is an active safety and property-damage condition; a leak that stops after the valve closes is more consistent with the pressurized supply path than a simple residual drain puddle.
-
Check 2
From the sink cabinet or another ordinary-access opening, photograph the hose, clamps, fittings, cabinet floor, and model label without pulling the secured dishwasher or removing panels.
Expected result: The damaged section is on the incoming supply route, on the drain route toward the sink or disposal, or is an internal short hose visible only after disassembly.
Next step: Send the photos and exact model 665.13963K017 to the property manager or qualified technician and leave the water shutoff closed until the route and replacement are confirmed.
Stop if: Do not crawl under the appliance, loosen a hidden clamp, or pull the unit forward to reach the hose.
Why this matters
Why: Supply and drain hoses have different water timing and connection paths. A section that cannot be identified without moving the built-in unit is outside a safe owner check.
-
Check 3
Classify when the water appeared by using the existing evidence: while idle, during fill, during washing, during draining, or after the cycle, and record whether water remained in the tub.
Expected result: A puddle appears before a cycle, only when filling, only while draining, or water remains in the tub after the drain stage.
Next step: Give the timing and remaining-water observation to the technician. Use the model-specific manual for any permitted filter or ordinary-access care step; do not conduct another cycle solely for diagnosis.
Stop if: Do not reopen a damaged hose connection or energize the dishwasher to watch for a leak.
Why this matters
Why: An idle or fill-time leak keeps the supply side in question; a drain-time leak points toward the drain route or its connection; residual water can also reflect a drain problem and does not identify a damaged hose by itself.
-
Check 4
Verify the model and rental repair authority before ordering anything: record 665.13963K017 exactly, retrieve its Kenmore manual, and report any pet or cabinet damage to the owner.
Expected result: The model label is readable and the hose location is known, or the model or hose identity remains uncertain.
Next step: Have the landlord or property manager approve the repair path and have a qualified technician match the hose and connections to the exact model documentation.
Stop if: Do not install a generic rubber tube, substitute a hose intended for another appliance, or make an unauthorized rental modification.
Why this matters
Why: Kenmore provides a model lookup for manuals, while the exact Reddit case shows that visually similar short hoses can be confused with a larger waste-water hose. A generic 665 label or photograph is not enough to establish compatibility or authorization.

Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
Water continues with the dishwasher idle, the supply shutoff will not stop it, or water is near an outlet, wiring, or other electrical part.
Do this next
Move away from the hazard, isolate power only if it is dry and safe to do so, keep the water supply closed, and contact the landlord or emergency qualified service. Do not inspect underneath the unit.
Why this path and its safety boundary
Why it matters: This is an active water or electrical hazard. The hose may not be the only failed part, and continued operation can increase property damage.
-
PATH 02Next step
What you see
The leak starts only while the dishwasher fills and stops after the under-sink valve is closed.
Do this next
Keep the valve closed and have the owner or a qualified technician verify the exact model-specific connection and replacement before restoring water.
Why this path and its safety boundary
Why it matters: The incoming supply line, its fitting, or an inlet-side connection is more likely than a drain-only hose, but the exact failed component is not identified by timing alone.
-
PATH 03Next step
What you see
The leak appears during draining or leaves water at the sink or disposal connection, while no leak is seen before the cycle.
Do this next
Do not run another cycle to confirm it. Provide the timing and photos to the property manager or technician and keep the dishwasher out of service.
Why this path and its safety boundary
Why it matters: The drain hose, clamp, routing, or sink/disposal connection is more likely. A drain restriction or another component can produce the same symptom.
-
PATH 04Next step
What you see
The damage is visible only on a short internal rubber section, or the dishwasher must be pulled from the cabinet to reach it.
Do this next
Stop at the external evidence, preserve the photos, and arrange authorized appliance service using the exact model and serial information.
Why this path and its safety boundary
Why it matters: The repair crosses the built-in appliance, plumbing, and rental-authority boundary. The exact Reddit case demonstrates that this model can have more than one visually similar hose section, so a photograph alone cannot select a part.
Helpful context
Understand the symptom
Treat a damaged hose as a water-control problem first
Do not start a cycle to locate the leak. If water is running, pooling near wiring, or reaching the floor, press Cancel only if the control responds normally and can be used without touching wet equipment. From a dry position, switch off the dishwasher circuit or unplug it only when the plug and surrounding area are dry, then close the manual water shutoff under the sink. Whirlpool's leak guidance identifies cracked or loose supply and drain lines as leak sources and directs owners to shut off power and the water supply when an active leak continues.
Identify which hose path is involved without moving the unit
With the appliance isolated, photograph the hose and the surrounding floor or cabinet from the opening under the sink or any other ordinary-access view. A water-supply connection is associated with filling and may stay pressurized while the dishwasher is idle; a drain line is associated with emptying the tub and its sink or disposal connection. The exact Reddit report for this model describes a short black rubber section near the front and separately discusses the white waste-water hose, but the commenters do not establish the part's identity conclusively. Use that report as a description of the symptom, not as a repair instruction.
Inspect only visible connections and preserve evidence
After the water is off, look for moisture, a split, chew marks, a pulled clamp, a kink, or a connection that has separated. Do not pull out a secured dishwasher, remove the lower access panel, reach underneath, loosen a hidden fitting, or test the hose by reopening the shutoff. Whirlpool's installation guidance says hose routing and connections vary by model and recommends following the owner's manual; the Kenmore manual lookup asks for the model number without special characters so the matching documents can be retrieved. Keep the photos and note whether water appeared while idle, filling, washing, or draining.
Handle the rental-property repair through the owner
The exact Reddit post describes this model in a rental and reports pet damage to a short rubber hose. That context changes the next decision: send the landlord or property manager the model and serial label, clear photos, the shutoff and power status, and the location and timing of the leak before attempting repair. A built-in hose may require moving the dishwasher or opening its base, and a replacement must be confirmed against the exact model and hose location. Keep the dishwasher out of service until the owner or a qualified appliance technician confirms the repair.
When checks do not resolve it
Need a professional?
Arrange authorized appliance service promptly when the hose is internal or inaccessible, the dishwasher is secured in the cabinet, the leak returns, the water shutoff does not isolate the leak, or the exact replacement cannot be confirmed. In a rental, notify the landlord or property manager before repair. Treat water near electrical parts, a wet plug, sparks, burning odor, or repeated breaker operation as an immediate safety stop.
Common questions
FAQ
Can I patch the damaged rubber hose temporarily?
Do not rely on tape, sealant, a generic tube, or a clamp added without confirming the hose and connection. Keep the water shutoff closed and have the exact model and hose path checked by the owner or a qualified technician.
Is the short black hose in the exact Reddit report definitely the drain hose?
No. The report contains differing community descriptions of the short hose and the larger white waste-water hose. It is useful evidence that the symptom occurred on this model, but it does not prove the part identity or compatibility.
What should a renter send to the landlord?
Send the model and serial label, clear photos of the damaged section and any water, when the leak appeared, whether the under-sink valve stopped it, whether the dishwasher is powered off, and whether water remains in the tub. Keep the appliance out of service until the repair is authorized.
