Can I replace dishwasher parts myself?
Yes, for Kenmore dishwasher model 66574364K2, we can replace many common parts ourselves if we shut off power and water first and follow the step-by-step procedures in the 66574364K2 owner's manual or the 66574364K2 installation guide. Simple mechanical parts are usually the best DIY starting point.
Good DIY repairs vs. better left to a pro
Usually DIY-friendly (basic tools, low risk):
- Door sealing issues: replace the dishwasher door seal WPW10509257
- Spray arm issues: replace the dishwasher spray arm WP8268874
- Fill problems caused by a sticking valve: replace the dishwasher water inlet valve W10844024
- Drain leaks from a cracked hose: replace the dishwasher drain hose WP3374077
- Rack rolling problems: replace the dishwasher dishrack roller assembly, lower WP8268645
Often better for a technician (more disassembly, electrical testing, or leak risk):
- Motor and pump repairs (for example, pump motor replacement)
- Wiring, control, or heater circuit troubleshooting
- Persistent leaks that are not clearly from a seal or hose
DIY safety checklist (do these every time)
- Turn off power at the breaker before opening panels or touching wiring
- Shut off the water supply valve under the sink
- Protect floors; keep towels ready and use a shallow pan for residual water
- Take photos of wire and hose routing before disconnecting anything
- Run the shortest cycle after the repair and check carefully for leaks
Quick planning table
| Repair type | Typical tools | What to verify after |
|---|---|---|
| Seal, rack, spray arm | Screwdriver, pliers | Door closes smoothly; no drips |
| Inlet valve, drain hose | Pliers, nut driver | No seepage at clamps; proper fill/drain |
| Motor/pump, electrical | Meter, advanced tools | No leaks; correct operation through a full cycle |
Why it matters
Dishwashers can hide small leaks until they cause cabinet or floor damage. The installation instructions also call out running a short cycle and checking for leaks after work, which is the fastest way to confirm the repair is solid.

How do I tell what model Kenmore dishwasher I have?
Your Kenmore dishwasher’s model number is usually printed on a label around the door opening, most often on the inner door frame or along the tub rim. For your unit, the model number format looks like 66574364K2, and you’ll use it to match the correct parts and instructions in the 66574364K2 owner’s manual.
Where to look first (fastest checks)
- Open the door and inspect the left and right inner door frame
- Check the top edge of the door and the tub opening lip
- Look on the tub wall near the front corners
- Wipe the area with a damp cloth; labels can be hard to read under residue
If you still can’t find the label
If the label is missing or unreadable, we use the next most common locations:
- Behind the toe-kick (lower access panel)
- On the side of the cabinet frame (visible when the unit is pulled forward)
- On the back of the dishwasher
- In your paperwork, including the 66574364K2 installation guide (model and serial are often referenced for service and inspection)
What the model number helps you do
The model number narrows down the exact Kenmore 665-series configuration so you get the right fit for items like racks, seals, and valves.
| What you’re doing | Why the model number matters |
|---|---|
| Ordering replacement parts | Prevents wrong-fit parts and returns |
| Troubleshooting symptoms | Matches the correct diagrams and procedures |
| Checking error codes | Points to the right Kenmore dishwasher code set |
Why it matters
Kenmore dishwashers can look identical across multiple model revisions; a single character difference can change the correct dishrack, door seal, or water inlet valve. Using the exact model number ensures we match your dishwasher’s parts list and repair guidance.

Is it worth repairing a Kenmore dishwasher?
Yes, repairing a Kenmore dishwasher like model 66574364K2 is usually worth it when the problem is a common wear item (leak, latch, drain issue) and the repair cost stays well below the price of a replacement. If the repair involves major components (pump motor or electronic control) and the dishwasher is older, replacement often makes more sense.
Quick way we decide: cost, age, and what failed
- Under 8 to 10 years old: repairs are typically a good value.
- Over 10 years old: repair only if it is a small, targeted fix.
- Repair cost rule: if the repair is under ~50% of replacement cost, we usually repair.
- Major component failures: pump motor, control board, or repeated leaks can push the decision toward replacement.
- One-time issue vs. recurring: repeated drain or wash problems usually indicate a bigger system issue.
Common repairs that are usually worth it on 66574364K2
These are frequent, straightforward fixes that can restore normal operation:
- Door leaking: replace the dishwasher door seal WPW10509257
- Door not latching or unit stops mid-cycle: replace the dishwasher door latch WP3380854
- Not filling or fills slowly: replace the dishwasher water inlet valve W10844024
- Poor wash coverage: inspect/replace the dishwasher spray arm WP8268874
- Not draining well: check the drain path and consider the dishwasher drain hose WP3374077
Repairs that often tilt toward replacement
| Repair type | Typical impact | Usual recommendation |
|---|---|---|
| Pump/motor failure (wash or drain) | High part cost, more labor | Replace if older; repair if newer and otherwise solid |
| Electronic control issues | Can be expensive and intermittent | Replace if out of warranty and older |
| Multiple failures close together | Indicates overall wear | Replace |
Why it matters
A dishwasher repair is most cost-effective when it restores reliability for several more years. Fixing a simple leak or latch problem prevents water damage and nuisance shutdowns, while avoiding the high cost of replacing a full appliance.
What to check before you spend money
Use the 66574364K2 owner’s manual to confirm basic troubleshooting and maintenance items first:
- Clean the filter area and check for debris around the sump
- Verify the water supply valve is fully open
- Confirm the drain hose routing (high loop/air gap setup)
- Run hot water at the sink before starting a cycle
- Note any blinking lights or error patterns and match them to a guide like Kenmore 665 model dishwasher error codes
