Kenmore 40514785420 24" built-in hybrid tub dishwasher - fingerprint resistant stainless steel Parts

Your Kenmore dishwasher’s model number is printed on the appliance identification label; on most built-in units it’s easiest to find by opening the door and checking the inner door frame or tub edge. For this series, the Use & Care Guide lists models as 405.1478# (the # is the color code).

Where to look on the dishwasher

Check these spots in order (door open, good lighting):

• Inner door frame (left or right side)
• Top edge of the door opening
• Tub wall near the door opening
• Along the side of the inner door panel
• Lower front area behind the toe-kick (if accessible)

What the model number looks like (and why it matters)

Kenmore model numbers are typically a long number with dots (example: 405.1478#) or a full model like 40514785420. Using the exact model number helps us match the correct parts, wiring, and troubleshooting steps in the 40514785420 owner's manual.

Quick ID tips

• Write down the full model number exactly as shown (including dots and any suffixes).
• Record the serial number too; it helps when checking production details.
• If the label is worn, take a clear photo and zoom in.

Model number formats you may see

Where you see it	Example format	What it means
Use & Care Guide	405.1478#	Model family; # indicates color code
Appliance label	40514785420	Full model used for parts lookup

Why it matters

Dishwashers can look identical but use different control boards, pumps, filters, or heating circuits. The correct model number keeps you from ordering the wrong replacement part and speeds up troubleshooting.

A small amount of clean water in the bottom of your Kenmore 40514785420 dishwasher is normal because it helps keep the drain seal lubricated. If you have standing water that does not drain after a completed cycle, the most common causes are a kinked drain hose, a clogged drain path, or a disposal knockout plug that was not removed.

What to check first (fast, no parts)

• Confirm the cycle fully finished (cancel or drain if your model has that option).
• Look for a kink or pinch in the drain hose under the sink; straighten it.
• If the drain hose connects to a garbage disposal, run the disposal until empty.
• If the dishwasher was newly installed, make sure the disposal knockout plug was removed.
• Clean the filter area in the bottom of the tub; food debris can slow or stop draining.

Troubleshooting checklist (in order)

1. Normal water vs. problem water: A shallow puddle around the outlet is expected; water covering the sump area or lingering for hours after a cycle points to a drain issue.
2. Drain hose routing: Verify the hose is not kinked and is routed correctly per the installation guide.
3. Drain path blockage: Check for clogs at the sink drain/disposal inlet where the dishwasher hose connects.
4. Filter and sump area: Remove debris that can restrict flow.

When a part is likely involved

If the hose and drain connection are clear but the dishwasher still will not drain, a restriction in the internal drain path or a failing pump is common.

Symptom	Most likely cause	What to do next
Small clean puddle only	Normal seal water	No repair needed
Water remains after cycle ends	Kink/clog/knockout plug	Correct hose, clear clog, remove plug
Hums but drains poorly	Pump obstruction or wear	Inspect for blockage; consider pump replacement

If you need to replace the drain pump/motor assembly, match parts by model and use the parts list for Kenmore 40514785420; one option shown for this model is the permanent magnet synchronous pump 11001011002369.

Why it matters

Standing water can lead to odors, poor wash performance, and re-depositing food soil on dishes. Restoring proper draining protects the tub, seals, and wash system.

Yes, repairing a Kenmore dishwasher like model 40514785420 is worth it when the problem is isolated (drain issue, heating problem, leak, or rack hardware) and the unit is otherwise cleaning well. Repairs typically cost less than replacement and avoid the time and disruption of installing a new built-in dishwasher; use the owner's manual to match symptoms to the right fix.

When repair is the smart choice

We recommend repairing when you see one clear failure and the dishwasher is in good overall condition.

• It won’t heat or dry well (often tied to the heater circuit)
• It won’t fill or fills slowly (water supply or valve related)
• It won’t drain well (filter, hose routing, or air gap issues)
• The rack is off-track or noisy (rack guides/supports)
• A small leak is traced to one area (not widespread tub damage)

Common repairs for this model (parts you can replace)

These are frequently replaced items available for Kenmore 40514785420:

• Heating elements 17476000006525 for poor drying or lukewarm wash water
• Inlet valve 17476000007453 for no fill or slow fill
• Main filter 12276000001513 for poor cleaning and drainage restrictions
• Lower sprayer 12276000012805 for weak spray and leftover soil
• Basket guider supporting holder 12176000008573 for rack alignment and smooth rolling

Quick decision guide (repair vs. replace)

What you’re seeing	Most likely path	Why
One function fails (heat, fill, drain)	Repair	Targeted part replacement restores performance
Repeated breakdowns in different systems	Replace	Costs and downtime add up
Heavy rust, severe tub damage, chronic leaks	Replace	Structural issues are not cost-effective
Cleaning is good but drying is weak	Repair	Heater, thermostat, or settings are usually the cause

Why it matters

A built-in dishwasher is tightly integrated with your cabinetry and plumbing. Repairing a single failed component often restores normal wash performance while avoiding installation work. The manual also notes that some drainage problems come from external plumbing devices like a drain air gap, which can be cleaned to restore draining. See the installation guide for shutoff procedures and installation-related checks.

A Kenmore 40514785420 built-in dishwasher typically lasts 10 years with normal use and basic maintenance (cleaning filters, using rinse aid correctly, and fixing leaks early). Heavy daily use, hard water, and poor draining shorten life; consistent care extends it.

Typical lifespan and what affects it

Most 24-inch built-in dishwashers like the Kenmore 40514785420 fall into a predictable service-life range.

• Typical service life: 10 years
• Common real-world range: 8 to 12 years
• Biggest lifespan factors: water quality, loading habits, and routine cleaning
• Most important maintenance item: keeping the filter system clean (prevents pump strain and poor washing)
• Most common wear areas: heating and drying components, wash pump, inlet valve, door sealing/hinge balance

For model-specific care steps and cleaning guidance, follow the maintenance section in the owner's manual.

Quick “repair or replace” guide

Use this as a practical way to decide whether a repair makes sense on an aging unit.

Dishwasher age	What we typically recommend	Why
0 to 5 years	Repair is usually worth it	Most parts still have strong remaining life
6 to 9 years	Repair if the issue is isolated	Costs can rise if multiple systems are wearing
10+ years	Replace unless the fix is minor	Major parts can exceed the value of the machine

Parts that commonly impact longevity on this model

If performance drops (poor drying, not cleaning well, not filling), these parts are frequent culprits.

• Main filter 12276000001513 (clogging can cause poor wash and extra load on the pump)
• Heating elements 17476000006525 (weak heating affects cleaning and drying)
• Inlet valve 17476000007453 (filling problems can lead to long cycles and poor results)
• Permanent magnet synchronous pump 11001011002369 (wash circulation issues)
• Thermostat 17476000006563 (temperature control problems)

Why it matters

Dishwashers usually fail gradually, not all at once. Knowing the expected lifespan helps you plan: routine care can prevent pump damage, reduce error codes, and keep cycles efficient so you get the full 10-year life from your Kenmore 40514785420.
