The F3E1 error code on your Whirlpool washer indicates trouble with the water level detection system. This common issue can stem from many causes, making it challenging to resolve. However, with the right approach, you can methodically troubleshoot the problem yourself. This guide outlines a process for systematically checking key components like the water level sensor, connections, and control board to track down the root of the F3E1 error.
Possible Causes of the F3E1 Error Code
The F3E1 error code indicates there is an issue with the washer’s water level system. This error can occur for a few different reasons. Here are some things to check that may be causing the F3E1 error:
Check Connections
It’s important to check the connections going from the tub to the air trap, from the air trap to the pressure hose, and from the pressure hose to the water level sensor. Make sure all of these connections are fitted tightly and securely. A loose connection anywhere along this path can cause the F3E1 error.
Go through each connection point and inspect it closely. Give the connections a gentle tug to see if they are loose. Tighten any loose connections. Also, check for damage like cracks or stripped threads. Damaged connections can allow air leaks, triggering the error code.
Inspect the Pressure Hose
The pressure hose is a key part of the water level system. Make sure to thoroughly inspect this hose. Check if the pressure hose is pinched, kinked, plugged, or leaking air anywhere along its length. Any of these issues can disrupt the airflow and cause the F3E1 error.
Gently bend and manipulate the hose while inspecting it to reveal any kinks or pinch points. Also, look inside the hose for any blockages and check for cracks or holes that could cause air leaks. Replace the pressure hose if you find any damage.
Tools Needed
Fixing the F3E1 error code requires gathering some basic tools. Having these tools ready will make the repair process smoother. Here are the recommended tools to have on hand:
Screwdriver Set
A set with screwdrivers of different sizes is essential. You’ll need both Phillips and flathead screwdrivers. The set should include small, medium, and large screwdrivers to handle different screw types.
Pliers
A standard pair of pliers allows you to get a good grip to loosen or tighten fittings. Pliers with insulated handles provide protection against electric shocks.
Adjustable Wrench
An adjustable wrench ensures you can loosen and tighten the various bolt and nut sizes. This tool provides versatility for the repair work.
Flashlight
A flashlight illuminates the interior of the washer so you can see connection points. It’s hard to make repairs on what you can’t see!
Cleaning Supplies
Rags, towels, scrub brushes, and cleaners make it easy to clean connection points and parts. Thorough cleaning improves connections.
Replacement Parts
Have any potentially needed replacement hoses, fittings, seals, etc. on hand before starting. This saves time and trips to the hardware store.
Safety Gear
Wear protective eyewear and gloves to keep safe during the repair.
Water Level Sensor Testing
The water level sensor is one of the main components to check when dealing with an F3E1 error. Here are systematic steps to test and inspect the water level sensor:
1. Run a Small Load
Start by running a small test load with just a few items. This will determine if the error recurs when the washer tries to fill.
2. Cancel and Drain
If the F3E1 error appears, press the START/PAUSE button to stop the cycle. Then press the POWER button to cancel the cycle completely and drain any water.
3. Unplug Washer
Make sure to unplug the washing machine before doing any further inspection or testing for safety.
4. Remove the Top and Rear Panels
The top and rear panels will need to be removed to access the internal tub, air trap, and hose connections.
5. Inspect Connections
Check that the connections between the tub, air trap, and pressure hose are securely attached and fitted properly. Tighten any loose connections.
6. Check for Blockages
Verify no water, suds, or debris are built up in the pressure hose or air trap. Blockages can affect airflow.
7. Inspect Sensor Harness
Check the connector J28 and inspect the wiring harness leading to the water level sensor. Make sure there is no damage.
8. Proceed to ACU Check
If the F3E1 error continues even after testing the sensor, proceed to check the ACU power supply.
ACU Power Check
If the water level sensor tests okay but the F3E1 error persists, there may be an issue with the ACU (Appliance Control Unit) power supply. Here are the steps to check the ACU power:
1. Disconnect Power
Unplug the washing machine or disconnect the power supply. This provides protection when working on the electrical components.
2. Remove Top Panel
Take off the top panel to gain access to the internal electronics.
3. Check ACU Connections
Inspect the connections to the ACU itself and to the interference filter. Make sure all connections are secure.
4. Restore Power
Plug the washer back in or restore the power supply.
5. Check the Voltage at the Filter
Use a multimeter to check for input line voltage at the interference filter input and output. Power should flow through the filter.
6. Verify ACU Input
Check for proper input line voltage going to the ACU. If voltage is missing, there is a problem.
7. Check ACU Status Light
Make sure the status light on the ACU is illuminated. If not, the ACU has an internal issue.
8. Check UI Voltage
Verify the User Interface (UI) is receiving the correct input voltage from the ACU.
9. Replace ACU
If power supply checks reveal a problem, the ACU will need to be replaced.

Conclusion
Dealing with appliance error codes can be frustrating. However, methodically troubleshooting the washer’s water level system can resolve an F3E1 error.
To recap, first inspect all connections and tubing for any leaks, blockages, or damage. Verify the water level sensor is functioning properly by running test cycles. If the sensor checks out, examine the power supply to the ACU.
With patience and by following a logical troubleshooting routine, you can get to the bottom of the F3E1 error. Determining the root cause then allows you to make the needed repairs, whether that’s fixing a connection, clearing a blockage, or replacing a faulty part.
Troubleshooting provides a great feeling of accomplishment when you diagnose and solve the problem on your own. You save the cost and hassle of a service call. Don’t be intimidated by appliance error codes. Arm yourself with the necessary tools, test systematically, and victory over that F3E1 error is within your reach!
