E2 F6 Whirlpool Washer Error Code: Meaning & Troubleshooting

Have you been running a cycle on your trusted Whirlpool washer when a code labeled as E2 F6 appeared on the washer? Now, you feel lost as you have no idea what this E2 F6 Whirlpool washer error code means and why it showed up? No worries!

The error code E2 F6 appears on a Whirlpool washer due to a communication error between the main control board (CCU) and the user interface (UI). The wire becoming loose or an issue with the appliance unit leads to this error code showing up on a Whirlpool washer.

Let’s dive deeper into the meaning of this particular error code and its causes. Needless to say, you can also find detailed solutions of exactly how you can get rid of this code on your washer.

What Does The F06 E02 Whirlpool Washer Error Code Mean?

On a Whirlpool washer, the F06 E02 code usually indicates a communication error.

When the user interface (UI) fails to establish a connection with the main control board of the washer, this error code shows up to alert you of the fact.

This user interface communication error can occur due to an underlying issue with the appliance control unit.

Meaning, the interface itself could fail to deliver the commands to the CCU. So, the central control unit does not detect any inputs and connection is not formed.

On the other hand, the wirings at the interface unit could be loose or faulty. This could also lead to a connection failure between the two units.

Why Does The F06 E02 Whirlpool Washer Error Code Appear?

Every error code that appears on the Whirlpool washer has a reason for its appearance.

Error code E02 F06 also has its own reasons and issues behind showing up. The communication failure to the CCU doesn’t happen for many reasons.

There are mainly two possible reasons this error code even shows up in the first place. They are

• Loose or faulty wiring at the interface
• Defective Central Control Unit/Board (CCU)

How to Fix E02 F06 Whirlpool Washer?

In order to get rid of the error code E2 F6 Whirlpool washer, you first need to conduct a proper test of the relative washer components.

Either it is the CCU that is faulty and needs replacement or the UI housing and wirings need to be changed.

During the diagnosis, you will inspect these components and decide which of the parts will get rid of the error code. The consequential diagnosis process is as instructed below:

Step 1: Remove the top panel

Unplug the Whirlpool washer from the power supply first. Then, remove the screws from the top panel and the panel off with a screwdriver.

Step 2: Secure The Wires

Inspect all of the wires inside that are connected between CCU and UI. If any of them are loose, secure them tightly. The harnesses should be connected to each other appropriately.

Step 3: Replace Burnt Components

Find any signs and remnants of the components inside being burnt. If you find any, locate the component and replace it accordingly. In case you’re not aware of such replacement procedures, take help of a professional.

Step 4: Check The Voltage At The Plug

Use a voltmeter or multimeter to do a power check at the power socket. Normally, the voltage should read around 120V at the power outlet when switched to AC. However, if the Whirlpool washer is on the bigger size, the voltage should be around 240V.

Step 5: Replace The Damaged Power Cord

If the voltage in this stage is fluctuating, inspect the power cord for any signs of damage. If you find any, replace the power cord itself with a newer one.

Step 6: Check and Replace The Interference Filter

Perform the voltage check mentioned in step 4 once again at the interference filter line. If the voltage is not within the mentioned range, the filter needs replacement.

Step 7: Check DC Voltage Of The CCU

Now, you need to test the power connections to the CCU to determine whether or not the CCU is defective. You can do that by a DC voltage test.

Use the multimeter to check the DC voltage at the 7 pins of the CCU. The test voltage found between the 2nd and 7th pin should be 5V. On the other hand, the test voltage between the 3rd and 7th pin needs to be 12V.

Step 8: Replace The Faulty Central Control Board

If the voltage range is not within the mentioned range, the CCU might be faulty. Try and do the same test again after connecting the washer to the power socket. If the result is the same, the CCU is definitely defective.

So, replacing the Central control unit of the washer is necessary. However, a CCU is extremely expensive to replace. In such circumstances, getting an entirely new washer is also a viable option.

Step 9: Test The DC Voltage Between UI and CCU

Now, time to check the connections between CCU and UI to know if the problem lies in the interface. Another DC voltage check will let you know of this.

Now, the correct DC voltage between the user interface and the central control unit should be 5V.

Put one end of the multimeter on the U17 of the CCU and the other end on the C2 of the user interface assembly. Check the multimeter for continuity or 5V voltage.

Step 10: Replace The User Interface Assembly

If you see the multimeter not showing any continuity between the two parts or the voltage is less than 5V, the user interface is not working. So, change the housing of the user interface along with the UI itself to get rid of this issue.
