Is your washing machine control board acting up? A faulty control board can throw your entire laundry routine into disarray. From washing machine error codes to machines that won’t start, drain, or spin, identifying the signs early can save you from expensive repairs. Your machine’s control board governs all major operations, and when it malfunctions, your washer may display erratic behavior or become completely unresponsive.
This guide by the Don’t Forget Blog will walk you through the telltale signs of a bad control board and help you determine whether a repair or replacement is necessary, ensuring you avoid unnecessary downtime.
What is the Control Board?
The washing machine control board is essentially the brain of your washing machine. It dictates how and when different components of the machine operate. When this part malfunctions, it can cause a wide array of issues. Often, it’s easy to misdiagnose the problem as something else, so it’s essential to know the specific signs of a bad control board.
Is Your Washing Machine Control Board Bad?
If your washing machine is acting strangely, there are several signs that could point to a faulty control board. If the display is blank, flickering, or showing error codes that cannot be reset, it might be due to a faulty control board. Additionally, if turning the dial or pressing buttons doesn’t change the settings or start a cycle, the control board might be failing.
Other common signs include the washer not starting at all, suddenly shutting off during a cycle, or changing settings on its own.
Since the control board is responsible for managing the machine’s operations, its malfunction can cause various unexpected behaviors. If you encounter these symptoms, testing or replacing the control board might be necessary to restore your washing machine to normal operation
Symptoms of a Bad Control Board
1. The Washing Machine Won’t Start
One of the clearest indicators of a malfunctioning control board is when your washing machine won’t start. While this can also result from a power issue, if the power source is working fine, the problem likely lies with the control board. A bad control board may prevent the machine from receiving the necessary signals to start a wash cycle.
2. Error Codes on the Display
Modern machines often provide error codes when something goes wrong. If you consistently see washing machine error codes that don’t reset or clear or codes that don’t correspond to common issues, the control board could malfunction.
3. The Washing Machine Won’t Spin
Another red flag is when the washing machine won’t spin properly. The spin cycle is an integral part of any wash, and if the control board is faulty, it might fail to send the necessary signals to initiate or complete this cycle.
4. Erratic Behavior or Malfunctions
If your washing machine seems to be doing its own thing—such as skipping cycles, pausing mid-cycle, or not completing a cycle—the control board may be at fault. This erratic behavior could stem from faulty signals sent to various machine parts.
5. No Response to Settings Changes
When you adjust settings but nothing changes, the issue may reside with the control board. A common symptom is the machine being stuck in one mode or the settings not registering when you press the buttons.
6. The Washing Machine Won’t Drain
A faulty control board might also affect the drainage system, leading to a situation where your washing machine won’t drain. This is particularly problematic as standing water can cause additional damage and mold growth.
7. Burning Smell
A more alarming sign of a bad control board is a burning smell. This can indicate overheating or damaged electrical components on the control board. If you detect this, immediately unplug your washing machine and inspect the board for visible damage.
Diagnosing a Faulty Control Board
Before jumping to conclusions, it is essential to conduct a series of checks to ensure the control board is the culprit.
1. Check the Power Supply
Ensure your machine is plugged in and the power outlet is functioning properly. A quick way to test this is by plugging in another appliance to see if it works.
2. Inspect the Wiring
Faulty wiring or loose connections can mimic the symptoms of a bad control board. Check all washing machine parts, such as the wiring harness, for any signs of damage or wear.
3. Run a Diagnostic Test
Most modern washing machines offer a diagnostic mode to help pinpoint issues, including control board errors. Refer to your manual on how to run a diagnostic test and interpret the washing machine error codes.
4. Inspect the Control Board Physically
If you’re comfortable working with electronics, remove the control board and inspect it for visible damage, like burnt areas, broken components, or loose connections.
Washing Machine Control Board Replacement or Repair?
Once you’ve identified the control board as the issue, you have two options: repair or replace.
1. Repairing the Control Board
Repairing your control board may involve replacing damaged components such as capacitors or fuses. However, this requires technical knowledge and experience with washing machine troubleshooting. If you lack this expertise, it’s best to consult a professional.
2. Replacing the Control Board
The more common solution is to replace the entire washing machine control board. While costly, it’s often the most effective way to resolve control board issues without additional headaches.
When Should You Call for Professional Help?
If diagnosing or repairing the control board feels overwhelming, don’t hesitate to seek professional help. Technicians specializing in washing machine repair can quickly assess the problem and recommend the best course of action. Search for “washing machine repairs near me” to find reputable service providers.
Preventing Control Board Failures
While control boards are electronic and susceptible to failure over time, proper washing machine maintenance can prolong their life. Here are a few tips to keep your machine running smoothly:
- Avoid Overloading: Putting too many clothes in your washer can strain the machine, causing wear on both mechanical and electronic parts.
- Use the Right Detergent: Excessive suds from using too much or improper detergent can affect the control board and other sensitive components.
- Regular Cleaning: Keep your washing machine clean, including the filter and detergent drawer, to prevent residue buildup.
- Inspect Wiring Regularly: Loose or damaged wires can lead to control board failures, so check connections periodically.
Frequently Asked Questions (FAQs)

Common signs include washing machine error codes, the machine not starting or spinning, erratic behavior, or no response to settings. Additionally, a burning smell or visible damage to the control board may indicate failure.
Can I repair a washing machine control board myself?
If you’re familiar with electronics and washing machine troubleshooting, you may be able to repair minor issues like replacing capacitors. However, for major faults, replacing the entire control board or seeking professional help is recommended.
How much does it cost to replace a washing machine control board?
The cost of washing machine control board replacement varies depending on your machine model. On average, replacement parts range from $100 to $300, and professional labor can add another $100 to $200.

Regular maintenance is key. Avoid overloading your machine, use the proper detergent, clean the machine periodically, and inspect wiring connections. Regular washing machine maintenance can help prolong the life of your control board.
Conclusion
A malfunctioning washing machine control board can disrupt your laundry routine and lead to expensive repairs. You can avoid further damage by recognizing the symptoms early—such as error codes or a machine that won’t start, spin, or drain.
Once diagnosed, you can choose to repair or replace the board, but if you’re not confident in your ability to fix it yourself, hiring a professional is your best option. With the right care and washing machine maintenance, you can extend the life of your control board and avoid common issues.
