If your Whirlpool washer is showing the F3/E1 error code, this guide will help you find the reason it is showing and how you can fix the problem.
Thankfully, removing this error code is usually quite straightforward, and you can do it yourself without having to call a technician.
Before we give you instructions for how to check the likely causes, let’s start by explaining what the error code means.
The error code F03/E01 indicates a problem with the water level. If your washer doesn’t get enough water, it will not be able to work correctly. Most of the time, this error code is a result of a faulty sensor, hose, or brand pipe.

The best place to start is to do a simple reset of your washer. Sometimes the error code can show when it shouldn’t, and a simple reset will remove the error code and let you use your washer again.

The next step is to check the water level sensor. The sensor monitors how much water is in your washing machine and then tells the control board to allow more water in or stop the water from flowing in. When it becomes faulty, your washing machine will stop working, and the F03/E01 error code might appear.
Here’s how to check the water level sensor:
The air trap pipe can become clogged with soapy foam and moisture, which can then make the F03/E01 error code appear on your washing machine’s display. When the pipe gets clogged, it cannot catch air, which will make it defective.
Here’s how to check the air trap pipe:
There is a wire harness between the pressure switch and the control module. Sometimes this wire harness can become defective if it gets damaged or corroded. To ensure the wires are working correctly, they need to be checked with a multimeter.
Here’s how to check the wiring:
If you have checked all of the other components listed above, your final option is to replace the main control board and then see if this solves the problem. The main control board is very difficult to test, so it’s a lot easier to just replace it. However, replacing your main control board isn’t guaranteed to work, so you might be better off buying a new washing machine instead.
