Can I replace dishwasher parts myself?
Yes. On the Kenmore 66517799990 dishwasher, we can usually replace simple, non-electrical parts (like a spray arm, door seal, or silverware basket) with basic tools as long as power is off and the water supply is shut off; follow the steps in the 66517799990 owner's manual.
Many repairs are straightforward, but anything involving wiring, grounding, or permanent electrical connections needs extra care.
Typically DIY-friendly:
- Replacing a worn door gasket such as the dishwasher door seal WPW10509257
- Swapping a clogged or damaged spray arm such as the dishwasher spray arm 675808
- Replacing a broken basket such as the silverware basket W10807920
- Tightening or replacing a spray arm fastener (for example, a spray arm nut)
- Reinstalling racks and checking that they seat correctly
Often better for a technician (or advanced DIY):
- Pump and motor issues (leaks, loud grinding, no wash action)
- Water inlet valve replacement and leak diagnosis
- Electrical troubleshooting (power supply, grounding, timer/control problems)
Before you remove panels or disconnect hoses, do these basics:
- Turn off the dishwasher circuit breaker (or unplug if accessible)
- Shut off the water supply valve to the dishwasher
- Protect the floor with towels; keep a shallow pan ready for water
- If you remove hoses, reinstall clamps fully and in the same position
- After reassembly, run a full cycle and check carefully for leaks
| What you’re replacing | Skill level | Common tools |
|---|---|---|
| Door seal, spray arm, basket | Basic DIY | Screwdriver, pliers |
| Track/rail, rack parts | Basic DIY | Screwdriver |
| Water inlet valve, pump/motor | Advanced DIY | Pliers, nut driver, multimeter |
Dishwashers combine water, heat, and electricity. The manual highlights proper grounding and warns that incorrect grounding can create an electric shock risk, so safe shutoff and correct reassembly are just as important as the part itself.

Yes. We still carry replacement parts for many Kenmore dishwashers, including model 66517799990. The key is matching parts to your exact model number so items like the door seal, spray arm, or silverware basket fit correctly and restore proper washing and sealing.
Use your model number exactly as shown on the model and serial label, then match the part by name and ID.

- Compare the part name and part ID before ordering
- Check whether the part is listed as In Stock or Check Availability
- Use diagrams in the 66517799990 owner's manual to confirm where the part installs

Is it worth repairing a Kenmore dishwasher?
Yes, repairing a Kenmore dishwasher like model 66517799990 is usually worth it when the problem is a wear item (seal, latch, spray arm) or a simple maintenance issue. It becomes less cost-effective when a major component (pump motor, timer) fails and the dishwasher is already near the end of its typical service life.
- If it’s leaking at the door, start with the door seal and door alignment.
- If it won’t latch or start, check the door latch and switch engagement.
- If dishes are dirty or gritty, inspect and clean spray arms and filters.
- If it fills slowly or not at all, suspect the water inlet valve or supply shutoff.
- If it won’t drain, check the drain hose routing and clogs.
- If the repair involves a pump motor or multiple major parts, compare repair cost to replacement.
Most dishwashers deliver about 10 years of service life. If your 66517799990 is under that range, repairs are commonly the better value, especially when the fix is a single part and you can do the work yourself.
| Situation | Usually worth repairing? | Why |
|---|---|---|
| Door leak, worn gasket | Yes | Low-to-moderate cost, high impact |
| Poor wash from clogged spray arm | Yes | Often cleaning or a single part |
| Door won’t stay closed | Yes | Common mechanical wear |
| Pump motor failure | Sometimes | Higher part cost and labor |
| Multiple symptoms, repeated breakdowns | No | Costs stack up quickly |
These are frequent, targeted fixes for this Kenmore dishwasher:
- Dishwasher door seal WPW10509257 (door leaks, moisture at corners)
- Dishwasher door latch WP3380854 (won’t start, door pops open)
- Dishwasher spray arm 675808 (poor cleaning, weak spray)
A focused repair restores cleaning performance and prevents water damage. Your Use and Care Guide also highlights routine care and troubleshooting steps that can prevent repeat problems and reduce service calls; see the 66517799990 owner's manual.
