Whirlpool dryers are known for their reliability and efficiency, but just like any other household appliance, they can become faulty over time and might begin to cause you headaches.
Sometimes, your dryer might show you an error code on the display indicating an issue with the appliance. This is normal and nothing to be alarmed about, but it does mean you’ll need to do some troubleshooting.
One of the most common faults that can occur with Whirlpool dryers is the F70 error code, which indicates a problem with the dryer’s control board.
This article will discuss the main causes of an F70 code on a Whirlpool dryer. We will also explain how to handle the situation if you find yourself with an F70 code and provide any other information you might need about the error.
What Causes Whirlpool Dryer F70 Code?
In a troubleshooting situation with any home appliance, you need to know how to identify the root cause before attempting to solve the problem.
Here are the three main possible causes of the F70 code on your Whirlpool electric dryer.
1. Failed User Interface Board
The user interface board, also known as the front control panel, is the component of the dryer that allows users to select the drying cycle, adjust the temperature and duration, and monitor the progress of the drying process.
If the user interface board fails, the dryer cannot communicate with the control board, which can lead to the F70 error code.
One of the most common causes of a failed user interface board is moisture. If the dryer is placed in a damp or humid environment or has come in contact with water, moisture can seep into the control panel and damage the circuit board.
Similarly, the user interface board can be damaged if the dryer is subjected to a power surge or other electrical anomaly. However, the user interface board may sometimes fail due to simple wear and tear over time.
2. Faulty Control Board
The control board is considered the “brain” of the Whirlpool dryer or its central control unit. It receives signals from the user interface board and controls the various components of the dryer, including the heating element, the motor, and the drum.
If the control board fails, the dryer will not be able to function correctly, and the F70 error code may be displayed. When this happens, the dryer won’t spin, heat up, or turn on at all.
Like the user interface board, the control board can be damaged by power surges, electrical anomalies, moisture, or even excessive heat. In addition, the control board can also fail due to manufacturing defects or simply due to wear and tear over time.
3. Loose Control Board Wire Connectors
In some cases, the F70 error code may be caused by loose wire connectors on the control board.
If your dryer has been shifted or moved for any reason, it’s possible that these wire connections were accidentally knocked loose, which can disrupt the flow of electricity and cause the dryer to malfunction.
Another possibility is that the wires have corroded over time. Corroded wires or electrical connectors that have suffered regular wear and tear will not be able to work properly either.
How To Fix the F70 Code on My Whirlpool Dryer?
Now that you know the potential causes, you’re better equipped to identify what’s causing the issue in your dryer. The following steps will help you figure out the problem, after which you’ll be able to make an informed decision about what to do about the fault.
1. Reset Your Dryer
Modern dryers rely heavily on electronics, and sometimes, the F70 error code on a Whirlpool dryer can be caused by a simple, temporary glitch in the system. In these cases, resetting the dryer can often solve the problem quickly and easily. Here’s how to do it:
- Turn off the dryer and unplug it from the power supply.
- Wait a few minutes to allow the electrical components to discharge.
- Plug the dryer back in and turn it on.
- Try running a drying cycle to see if the error code has been resolved.
If the F70 error code persists after resetting the dryer, there may be an issue with the user interface board, control board connectors, or main control board.
2. Check the User Interface Board
If resetting the dryer does not solve the problem, the next step is to check the user interface board, which allows you to control your dryer by selecting your dry cycle, setting times, turning it on and off, etc.
If the user interface board is damaged or malfunctioning, it can cause the F70 error code to appear.
To check the user board, remove the control panel from the dryer through the access panels located at the front or back of your appliance. Check your user manual to get specific instructions for different dryer models.
Once the control panel is removed, the user interface board can be inspected for signs of damage or corrosion. If the board appears damaged, it might need to be replaced.
3. Check the Control Board Connectors
A loose connection or a faulty connector can cause communication issues between the control board and the user interface board, resulting in the F70 code. As discussed above, you’ll want to check the control board connector by removing the dryer’s access panels and locating the control board.
Inspect the control board connectors for signs of damage, corrosion, or loose connections. If any connectors are damaged or have a loose connection, you will have to replace the connector or repair the connection.
If the control board connectors appear to be in good condition, you can move on to the next step.
4. Check the Main Control Board
If the F70 code persists after checking the user interface board and control board connectors, the issue is likely with the main control board itself.
If there is a problem with the main control board, this will cause those communication issues that result in the F70 code. To check the main control board, disconnect the dryer from the electrical outlet and remove both the top and front panels.
Locate the main control board and inspect it for signs of any damage, wear, or corrosion. If the main control board isn’t in great shape, it will probably need replacing. Get in touch with an appliance technician if this is the case.
If the main control board appears to be in good condition, though, you can use a multimeter to test the board’s continuity and voltage. If the board has no continuity or voltage, you will still need to replace it.
How Can I Prevent the F70 Code on My Whirlpool Dryer?
If you want to keep your Whirlpool dryer functioning optimally for many years, then you’ll naturally want to avoid the F70 code since this code typically implies a serious problem to be solved.
While we can never completely prevent faults in our appliances, there are a few things we can do to take good care of them and hopefully avoid having issues.
1. Proper Maintenance
Regular dryer maintenance is crucial to prevent issues like the F70 code. This simply implies taking good care of the machineย – keep it clean and watch for damage.
Clean the lint filter before every use, and clean the dryer’s exhaust vent at least once a year. This should help you keep it in good shape, and you’ll notice quickly if anything is amiss.
2. Avoid Overloading
Overloading your dryer can cause it to work harder than necessary, leading to issues like the F70 code and others, such as a leaking dryer. Be sure to follow the manufacturer’s recommendations for load capacity – you can find this information in your user manual.
3. Use the Dryer Properly
Make sure that you only use your dryer according to the instructions. Avoid drying items that are not meant to be dried, like rubber or plastic.
Also, avoid drying items that are excessively wet since this can be extra heavy and put pressure on your dryer.
4. Check for Loose Connections
Occasionally, you should check out the connections between the user interface board, control board connectors, and main control board to ensure they are secure and tight.
Being preemptive about this could help you identify and rectify anything coming loose before it causes a real problem.
5. Keep the Applienace in a Dry Area
As we’ve discussed, moisture can cause issues with the dryer’s electronic components, leading to circuit communication issues. Keep your dryer in a dry area to prevent moisture from affecting its performance.
