What is the most common failure on a dishwasher?
The most common dishwasher failure is a drainage problem: water stays in the tub because the filter area, drain path, or drain pump gets restricted by food debris. On the Jenn-Air JDTSS247HS0, we also commonly see leaks at the door and “won’t start” symptoms tied to the door latch.
Most common failures (and what you’ll notice)
- Poor draining: standing water at the end of the cycle, gurgling, or a dirty sump
- Not cleaning well: gritty dishes, cloudy glassware, or detergent left in the dispenser
- Leaks: water at the front corners or along the bottom of the door
- Won’t start or stops mid-cycle: door not fully latching, intermittent control response
- No heat or poor drying: dishes come out cool and wet, cycle takes longer than normal
Quick checks we recommend first
- Remove and rinse the filter area and check for broken glass, labels, or bones.
- Confirm the sink drain and garbage disposal are clear (a partially blocked sink drain can slow dishwasher draining).
- Check the drain hose routing for kinks and make sure it has a proper high loop.
- Run hot water at the kitchen faucet for 30 to 60 seconds before starting a cycle.
- Verify the door closes firmly; if it feels loose or “bouncy,” inspect the latch.
Common failure points and matching parts
| Symptom | Likely area | Example part for JDTSS247HS0 |
|---|---|---|
| Standing water | Drain system | Dishwasher drain pump WPW10531320 |
| Water at bottom of door | Door sealing | Dishwasher door seal, lower W10909089 |
| Won’t start, door won’t stay shut | Latch | Dishwasher door latch WPW10653840 |
| Poor fill, weak wash | Water supply | Dishwasher water inlet valve WPW10327249 |
Why it matters
Drain and seal issues usually start small (slow drain, occasional drip) but they can quickly lead to odors, poor cleaning, and repeated cycle interruptions. Catching the restriction or worn seal early keeps the wash system and motor from working harder than necessary.

What is the most expensive part of a dishwasher?
In most dishwashers (including the Jenn-Air JDTSS247HS0), the most expensive repair is usually an electronic assembly such as the control board or console, because it manages cycle selection, timing, and key functions. Large assemblies like a pump and motor can also be among the highest-cost parts.
What’s typically the priciest (and why)
These parts cost more because they combine electronics, motors, seals, or multiple subcomponents into one assembly.
- Electronic control/console assemblies: user interface plus control logic
- Pump and motor assemblies: main wash circulation power and water movement
- Sump and seal assemblies: multiple seals and housings that prevent leaks
- Tub or door assemblies: large, model-specific structural parts
- Specialty motors/valves: diverter motors and inlet valves can add up
Examples of higher-cost parts for JDTSS247HS0
Here are a few parts on this model that are commonly on the higher end because they are complete assemblies.
| Part type | Example part on this model | Why it can be expensive |
|---|---|---|
| Pump and motor assembly | Pump and motor assembly W10899563 | Motor plus pump components in one unit |
| Console assembly | Console assembly (includes insert) (black) W11337647 | Electronics and user interface together |
| Sump and seal assembly | Dishwasher sump and seal assembly WPW10455268 | Multiple seals and molded housings |
How we recommend deciding whether to replace the “most expensive” part
Before buying a high-dollar part, we use these checks to avoid replacing the wrong component.
- Confirm the symptom: no power, no drain, no wash action, leaking, or error behavior
- Check simple causes first: tripped breaker, loose wiring, clogged filter, kinked drain hose
- Match the failure to the system: drain problems often point to the drain pump or hose; wash problems often point to the circulation pump
- Inspect for visible damage: burned connectors, corrosion, cracked housings, leaking seals
- Compare repair cost vs. dishwasher age and overall condition
Why it matters
The “most expensive part” is often expensive because it is hard to diagnose and not always the root cause. A quick symptom-based check helps you avoid unnecessary returns and gets your Jenn-Air dishwasher running sooner.

What are the commonly replaced parts in a dishwasher?
In the Jenn-Air JDTSS247HS0 dishwasher, the most commonly replaced parts are the wash and drain components, door parts that affect starting and sealing, and rack hardware that wears from daily loading. These parts typically fail from clogs, leaks, heat stress, or normal mechanical wear.
Most common dishwasher parts that get replaced
- Drain and wash system: drain pump, pump and motor, hoses, sump seals
- Heating and drying: heating element
- Filling: water inlet valve
- Door operation: door latch, door balance link, door hinge, lower door seal
- Racks and adjusters: rack adjusters, rack rails, tine clips, rack assemblies
- Filtration: filter cup and related filter components
Model-specific examples for JDTSS247HS0
If you are troubleshooting a symptom, these are frequent matches for this model:
| Symptom | Parts to check first | What usually happens |
|---|---|---|
| Not draining or water left in tub | Drain pump, drain hose | Pump jammed, hose kinked or restricted |
| Not filling or fills slowly | Water inlet valve | Valve screen clogged or valve fails electrically |
| Poor cleaning or weak spray | Pump and motor, diverter motor, filter cup | Low circulation, misdirected flow, filter blockage |
| Not drying or water stays cool | Element assembly | Heater open or heat circuit issue |
| Door won’t latch or won’t start | Door latch, door balance link | Latch switch not closing, door not aligning |
Parts on this model we see replaced often
- Dishwasher door latch WPW10653840
- Dishwasher water inlet valve WPW10327249
- Dishwasher drain pump WPW10531320
- Element assembly W10703867
- Dishwasher dishrack adjuster WPW10546503
Why it matters
Replacing the right part first prevents repeat leaks, protects the circulation pump and motor from running dry or restricted, and restores proper wash temperature and detergent performance. Keeping filters and spray paths clear also reduces strain on the drain pump and diverter.
