What Is the WD21X35479 Dishwasher Control Board?
The WD21X35479 Dishwasher Configured Machine Control Board is an electronic replacement part for compatible dishwashers. It controls key dishwasher functions, including cycle response, start behavior, and communication with other electronic components.
The listing identifies it as Genuine OEM Part # WD21X35479. That matters because dishwasher control boards must match the exact part family, connector layout, and programming needs of the appliance.
This part also replaces several earlier control board numbers, including WD21X32058, WD21X32060, WD21X33682, WD21X33684, WD21X33685, WD21X34898, WD21X34978, WD21X35058, WD21X35459, and WD21X35478. If your old board or parts diagram lists one of those numbers, the WD21X35479 may be the correct updated replacement.
Who It’s For
- Homeowners whose dishwasher parts diagram, old control board label, or repair manual lists WD21X35479.
- DIY repair buyers who can safely disconnect power and match every connector before installation.
- Appliance repair customers trying to fix a dishwasher that will not start, has no display, or behaves unpredictably during cycles.
Who Should Skip It
- You should skip it if your dishwasher model number does not match WD21X35479 or one of its replacement numbers.
- You should skip it if you cannot confirm the board before installation, because installed electrical parts are often not refundable.
- You should hire a technician if you are not comfortable working around appliance wiring and electrical connectors.
Feature-by-Feature Review
OEM Part Match and Replacement Coverage
The strongest reason to choose the WD21X35479 is its replacement coverage. The Amazon listing names WD21X35479 as the main OEM part number and lists multiple older part numbers it replaces.
This helps if your dishwasher originally used WD21X32058, WD21X33682, WD21X35058, or another listed number. Instead of hunting for an older board, you can use the updated replacement part when your model confirms compatibility.
The key word is “confirms.” A dishwasher control board is not a universal part. Even boards that look similar can use different programming, wire layouts, or connector positions.
Installation and Fit
The WD21X35479 weighs 1 pound, so the part itself is not difficult to handle. The real challenge is proper fit, safe power disconnection, and correct wire placement.
Before installation, unplug the dishwasher or turn off power at the breaker. Take a photo of the old board and connectors before removing anything, because that photo can help you match the wiring during reassembly.
The listing warns buyers not to install the part if it does not match the appliance. That warning matters because installed parts may not qualify for a refund or exchange.
Build and Component Role
A dishwasher configured machine control board acts like the electronic decision center of the appliance. It helps manage cycle commands and tells other parts when to start, stop, fill, drain, heat, or respond to user input.
The WD21X35479 is a replacement board, not a cosmetic accessory. You buy it when the dishwasher shows control-related symptoms, such as no display, failure to start, incomplete cycles, or unpredictable operation.
Because this is an internal electronic part, the value comes from exact compatibility. A correctly matched control board can restore normal function, but a mismatched board can waste time and create a return problem.
Return Policy and Buyer Risk
The listing shows a 30-day refund/replacement return window. It also states that returned items must remain in new and re-saleable condition.
That return rule creates one of the biggest buyer risks with this part. You should verify your dishwasher model number, old board number, and replacement number before you install the board.
Do not test-fit the part casually if you are unsure. Once an electrical control board shows signs of installation, a seller may refuse a refund or exchange.
Compatibility Check
The WD21X35479 replaces part numbers WD21X32058, WD21X32060, WD21X33682, WD21X33684, WD21X33685, WD21X34898, WD21X34978, WD21X35058, WD21X35459, and WD21X35478. That list gives you a starting point, but it does not replace a model-level fit check.
Use the model number on your dishwasher’s rating plate before ordering. You can usually find that plate around the door frame or inside edge of the dishwasher door.
If your dishwasher model number and old board part number do not line up with the listing, contact the seller or an appliance parts supplier before purchase. A short compatibility check can save you from buying an electrical part you cannot return after installation.
How It Performs in Real Use
When the Dishwasher Will Not Start
If your dishwasher receives power but will not start, the control board may be one possible failure point. The WD21X35479 can help when a technician or parts check confirms the existing board has failed.
When the Display Is Dead
A dead display can come from several problems, including power supply issues, wiring faults, user interface failure, or main board failure. The WD21X35479 only makes sense after you rule out simpler issues and confirm the board number.
When Cycles Act Unpredictably
A failing control board may cause interrupted cycles, nonresponsive buttons, or strange cycle behavior. In that situation, the WD21X35479 can restore normal operation if the original board number matches the listed replacement range.
Pros and Cons
Pros
- Genuine OEM Part # WD21X35479, which helps reduce fit risk when your appliance matches the part number.
- Replaces multiple earlier part numbers, including WD21X32058, WD21X33682, and WD21X35058.
- 1-pound item weight makes the board easy to handle during installation.
- Useful for control-related dishwasher problems, such as no start, dead display, or erratic cycles.
- Clear return warning helps you understand the risk before installing the part.
Cons
- Compatibility depends on your exact dishwasher model and old board number.
- Installed electrical parts may not be refundable, even within the return window.
- The Amazon listing does not provide detailed dimensions or a full installation guide.
Is It Worth the Price?
The WD21X35479 can be a strong value for the price if it prevents a full dishwasher replacement. Control board repairs often make sense when the dishwasher is otherwise in good condition and the failed part is clearly identified.
The value drops if you guess at compatibility. A control board is not the part to buy based on appearance alone, because one wrong connector or wrong programmed board can stop the repair.
You get the most value from this purchase when you have already confirmed the model number, checked the old board label, and matched it to WD21X35479 or one of the listed replacement numbers.
How It Compares to Alternatives
If you need the same part family, compatible WD21X35479 boards from other sellers may appear as lower-cost alternatives. Those options can work for some buyers, but you should check whether they are OEM, aftermarket, refurbished, or open-box before ordering.
GE WD21X24900 and WD21X24901 boards also appear in the dishwasher control board category, but they are not automatic substitutes for WD21X35479. Choose the WD21X35479 only when your dishwasher model or old board number supports that exact replacement path.
Price Competitiveness and Customer Interaction
The WD21X35479 listing includes a lower-price feedback option. That feature lets shoppers report a better online or offline price, including shipping cost and date of the price.
| Feature | Description | Buyer Impact |
|---|---|---|
| Price Feedback | Customers can report lower prices | Helps Amazon track competitive pricing |
| Shipping Cost Field | Feedback form includes shipping cost | Helps compare total purchase cost |
| Sign-in Requirement | Feedback requires account sign-in | Adds accountability to reports |
| Return Policy | 30-day refund/replacement shown on listing | Useful only if the item remains eligible |
| Installation Warning | Do not install if the part does not match | Reduces refund risk for mismatched boards |
Frequently Asked Questions
How Do I Install the WD21X35479 Control Board?
Turn off power to the dishwasher before you touch the control board. Photograph the original wiring layout, remove the old board carefully, match each connector, secure the new board, and test the dishwasher only after reassembly.
What Appliances Are Compatible With This Control Board?
The listing identifies WD21X35479 as the main part number and says it replaces WD21X32058, WD21X32060, WD21X33682, WD21X33684, WD21X33685, WD21X34898, WD21X34978, WD21X35058, WD21X35459, and WD21X35478. You still need to confirm your dishwasher model number before ordering.
Is Technical Support Available for Installation Issues?
The source article mentions technical support, but the Amazon listing does not clearly describe a full support program. Contact the seller before purchase if you need model verification or installation help.
What Are the Common Symptoms of a Faulty Control Board?
Common control-board-related symptoms can include failure to start, no display, unresponsive buttons, incomplete cycles, or erratic dishwasher behavior. These symptoms can also come from wiring, door latch, power, or user interface problems, so confirm the diagnosis before buying.
Can I Find Installation Videos Online for This Part?
Yes, you can find general dishwasher control board replacement videos online. Use them for process guidance, but follow your dishwasher model’s parts diagram and safety steps because connector locations can vary.
Can I Return the WD21X35479 After Installing It?
You should not assume you can return it after installation. The listing says returned items must be in new and re-saleable condition, and it warns that installed mismatched parts may not be refundable.
The Bottom Line
The WD21X35479 Dishwasher Configured Machine Control Board earns an 8/10 rating because it offers a clear OEM part number, a wide replacement-number list, and a practical repair path for compatible dishwashers. You should buy it only after you confirm your dishwasher model and old board number.
Skip it if you are guessing, if your appliance uses a different board family, or if you cannot safely handle electrical appliance repair. For the right dishwasher, this board can be a smart buy that helps restore normal cycle control without replacing the whole appliance.
