F3E1 Whirlpool Washer Error Code: A Troubleshooting Guide For Water Level System Error

A Whirlpool front load washer is a convenient and efficient appliance, but occasionally issues like the F3E1 error code can disrupt its performance. This fault code on a Whirlpool front load washer indicates an out-of-range pressure signal detected by the Appliance Control Unit (ACU). This error code is associated with the water level system, which is responsible for accurately detecting and controlling the water level in the washer’s tub.

Understanding and troubleshooting the error code is essential for resolving the underlying issue and getting your washer back to its optimal functioning state. By following the step-by-step instructions and guidelines in this troubleshooting guide, you’ll be equipped to identify potential causes, check connections and components, and determine if any parts need replacement. These instructions can also be located on the tech sheet on the appliance. 

In the sections that follow, we will delve into the possible causes of the F3E1 error code and provide a detailed outline of the testing procedures. By following this guide, you’ll have the necessary knowledge to troubleshoot and resolve the F3E1 error code on your Whirlpool front load washer, ensuring its optimal performance and longevity.

Possible Causes of the F3E1 Error Code

The F3E1 error code on a Whirlpool front load washer indicates an out-of-range pressure signal detected by the Appliance Control Unit (ACU). Understanding the potential causes of this error code is crucial for effective troubleshooting. Here are some possible causes to consider:

Check connections from tub to air trap, air trap to pressure hose, and pressure hose to water level sensor:

• Loose or disconnected connections between the tub, air trap, pressure hose, and water level sensor can result in erratic pressure readings and trigger the F3E1 error code. Ensure that all connections are securely attached and free from any damage.

Is the pressure hose pinched, kinked, plugged, or leaking air?

• A pinched, kinked, plugged, or damaged pressure hose can disrupt the water level system’s functionality and cause pressure signal irregularities. Inspect the pressure hose thoroughly to ensure it is not obstructed or leaking air.

These are the common causes associated with the this error code. By addressing these potential issues, you can eliminate simple problems and move towards more in-depth troubleshooting if necessary. 

Tools Needed

• Screwdriver set: A set of Phillips and flathead screwdrivers will be handy for removing screws and accessing various parts of the washer.

• Pliers: Pliers will help you disconnect and reconnect hose clamps. They may also help manipulate small components during the troubleshooting process.

• Adjustable wrench: An adjustable wrench is useful for loosening and tightening nuts and bolts.

• Flashlight: A flashlight will help you inspect hard-to-reach areas, such as the drain pump and filter, for any obstructions or debris.

• Cleaning supplies: Have some cleaning supplies, such as a bucket, mild detergent, and a cloth, ready to clean the drain pump filter and other components if necessary.

• Replacement parts: Depending on the troubleshooting results, you may need to order and have replacement parts on hand, such as a new drain pump or water level sensor. Ensure you have the correct parts by checking your model number and parts list at www.appliancepartspros.com. 

Exercise caution and ensure the washer is unplugged before working on any electrical components. 

Water Level Sensor Testing

To diagnose and troubleshoot the F3E1 error code on your Whirlpool front load washer, it’s important to perform Water Level Sensor Test. This test will help you assess the water level sensor, ACU, and wiring. Follow the steps below:

1. Check the water level sensor by running a small load. During this cycle, the valves should automatically turn off after sensing the correct water level in the tub. If the water level sensor functions properly and the error code does not persist, you can skip the remaining steps. However, if the error code persists, proceed to the next step.
2. Press the START/PAUSE button to stop the cycle, and then press the POWER button to cancel the cycle and drain the water from the tub.
3. Unplug the washer from the power outlet or disconnect the power supply to ensure safety during the troubleshooting process.
4. Remove the top and rear panels of the washer to access the tub, air trap, and pressure hose connections. The water level sensor is located at the top right rear of the cabinet.
5. Check the connections from the tub to the air trap, air trap to the pressure hose, and pressure hose to the water level sensor. Ensure that all connections are securely attached.
6. Verify that there is no water, suds, or debris present in the hose or air trap. Disconnect the hose from the water level sensor, clean the air trap, and remove any water, suds, or debris from the hose by blowing into it.
7. Visually check that connector J28 is fully inserted into the ACU. Additionally, ensure that the water level sensor harness is securely connected to the sensor and not damaged. 
8. If the error code persists after completing these steps, proceed to the ACU Power Check, which will be covered in the next section of this troubleshooting guide.

ACU Power Check

If you have performed the Water Level Sensor test and the F3E1 error code still persists on your Whirlpool front load washer, it’s time to proceed with the ACU Power Check. This test will help you determine if there are any power-related issues with the Appliance Control Unit (ACU). Follow the steps below:

1. Disconnect the power cord to ensure safety during the troubleshooting process.
2. Remove the top panel of the washer to access the machine electronics.
3. Ensure all connections to the interference filter (IF) are secure.
4. Check all connections to the ACU and verify that they are fully inserted.
5. Plug in the washer or reconnect the power supply.
6. Using a voltmeter set to AC, check for line voltage at the input of the interference filter. If line voltage is present, proceed to step 8. If line voltage is not present, verify the continuity of the power cord. If the power cord fails the continuity check, replace it with a new one.
7. With the voltmeter still set to AC, check for line voltage at the output of the interference filter. If line voltage is present, proceed to step 9. If line voltage is not present, replace the interference filter.
8. Set the voltmeter to AC and check for input line voltage to the ACU across pins 1 and 2 of connector J8 AC In (IF filter). If line voltage is present, proceed to step 10. If line voltage is not present, check the harnesses and connections between the filter and the ACU. Visually inspect the inside of the connector housing for any damaged terminals and repair them as necessary.
9. Check the status light on the ACU. After plugging in the ACU, the LED will blink for 10 seconds, and then it should become solidly lit. Here’s what the LED indicates:
   • If the LED is not lit, it means there is no 5 volts DC supply to the microcontroller. In this case, the ACU needs to be replaced.
   • If the LED is not solidly lit after 10 seconds of blinking upon being powered up, it indicates that the microcontroller is not responding. Replace the ACU.
   • If the LED remains solidly lit during washer operation, it suggests that the ACU is likely functioning correctly, and the issue may lie elsewhere.Check the UI (User Interface) input voltage. Verify that there is 5V between pin 1 and 3 at connector J18 on the board.

If the results of this test indicate a faulty ACU, it will be necessary to replace it.
