If your whirlpool dryer is displaying an F70 error code, you’re in the right place.
In this article, we will give you step-by-step instructions for how to find the cause of the problem and fix it. But before we do that, let’s briefly discuss what the F70 error code means.
The F70 Error Code means that the user interface board cannot communicate with the main control board. This means that when you try to set your dryer the main control board doesn’t get the message/signal, so your dryer won’t be able to work properly.

The best place to start is to try to reset your Whirlpool dryer. This is because sometimes the error code can be displayed when it shouldn’t, so a simple reset will solve the problem.
Here’s how to reset your Whirlpool dryer:
The user interface board is a printed circuit board that works with the display unit and the control board buttons to ensure your dryer operates how you want it to. Sometimes the user interface board can wear out over time, or it can short out during a power surge. In some rare cases, it can also become damaged if it comes in contact with water or your dryer becomes extremely hot. If the board becomes defective, it will need to be replaced, as it cannot be repaired.
Here’s how to replace the user interface board:
Another potential reason why your Whirlpool dryer is displaying an F70 error code is if the wires that are connected to the control board are defective. Over time the connectors can become corroded and will stop working, or in some cases, the connectors can become loose.
Here’s how to check the control board connectors:
The main control board is like the brain of your dryer. It tells all of the components in your dryer what to do. When it becomes defective, your dryer might stop working, and the F70 error code might show.
The main control board can be defective for a number of reasons. Sometimes it can just be due to normal wear and tear, or sometimes it’s due to an electrical surge occurring or through water and heat damage.
Replacing the main control board can be quite expensive and isn’t a guarantee that your dryer will work properly again. Instead of replacing the main control board, you might be better off simply purchasing a new dryer – especially if the dryer is old.
