F06 E02 Error Code Whirlpool Washer (This is the FIX)

F06 E02 Error Code Whirlpool Washer (This is the FIX)

Error codes indicate that your washer is detecting some issues in specific units of its system. It is one of the many advantages of modern household equipment. These codes help narrow down the washer problem to apply the proper solution.

So when you see the F06 E02 on your Whirlpool washer, what message is your washer relaying to you?

The Whirlpool error code F06 E02 signals an error in communication between two board units. Irregularity in the circuit breaker’s power supply can be one reason for this error code. In other situations, the error code is a result of faulty boards. It is crucial to find the specific reason before attempting a fix.

Here, we’ll look at the meaning and reasons for the F06 E02 error on Whirlpool washer. You also get a comprehensive guide on the steps involved in solving the problems.

Reasons for F06 E02 Error Code Whirlpool Washer and Fixes To It

The F06 E02 Error code on your Whirlpool washer is one of the different error codes that can appear while using the machine. A good understanding of the meaning of error codes can illuminate the possible reasons for the error.

The F06 E02 error code means a communication problem between the CCU (Central Control Unit) and the UI ( User Interface).

Note that this error code results from issues between two different units. Hence, faults or defects to the units are the reasons for these issues. The appropriate fixes also focus on these units.

However, there can be various reasons for a single error code. So the F06 E02 can result from multiple faults. So it would be best to narrow down the exact trigger for the error code. As a result, it is necessary to correctly diagnose the problem before attempting any solution or fix.

There are two steps here if you desire to clear the error code properly:

  • Diagnose or find out and ascertain the exact problem
  • Apply the appropriate solution or fix for the diagnosis

Here are common reasons for the F06 E02 error code, the steps to diagnose the issue, and the possible fix to the error.

Power Supply to the Central Control Unit

The CCU uses both AC and DC power for proper functioning. Suppose there are issues with this power supply. In that case, it affects communication between the CCU and other panels, including the User Interface. Proper diagnostic steps will help you confirm which part of the cables needs replacing or fixing.

Diagnosis and Possible Solution

You should remove the washer top cover using a quarter-inch nut driver for these diagnostic steps. It would be best if you also had a multimeter or a voltmeter to test for power supply.

Here are the steps involved:

  • Disconnect the Whirlpool washing machine from the home power supply
  • Using the nut driver, remove the screws at the back of the washer. The screws are at the top. They connect the top lid to the rest of the washer.
  • Slide the cover backward and lift it gently. The removal shows all the cable that connects to the CCU. Be careful while removing the top to avoid cuts from the sharp edges.
  • First, check for any loose connection or cables not fitting correctly to their receptor. You can remove and reinsert all the wires.
  • Check for burnt cables or panels. A smoky smell can also help identify burns. Replace burnt lines and test to see if the error code is gone.
  • The next step is to check the voltage supply from the wall socket. The power supply is an alternate current. Hence, you should set the voltmeter to AC accordingly.
  • The reading should be around 120V for a normal-sized Whirlpool washer. If you have a bigger model, the voltage reading should be approximately 240V. Check your user manual to confirm the voltage requirement for your model.
  • Next, check the current supply in the power cord.
  • Check the voltage supply at the filter and replace either the power cord or filter cord, depending on the unit with issues.
  • Check the input pin in the CCU for proper voltage supply.
  • Next is to check the DC within the terminals of the board. There are seven pins to test. Here is the list of pins to check:
    • Test the voltage from the 7th to the 2nd pin. The voltage should be around 5V DC.
    • Test the voltage from the 3rd to the 2nd pin. The voltage should be around 12V DC.
  • Check for unusual readings or open loops in any of the two tests. This reading shows that the board is faulty.
  • Replace the Central Control Board.

However, if there are no issues with the power supply, you can move on to the following reason for this error. Also, if you have replaced or fixed any cable and the error code remains, you should check the next option.

Severed Continuity between the Central Control Unit and User Interface

The two panels have cables connecting them for proper functioning. When there are issues with these cables, communication between the systems breaks down. Hence, the Whirlpool washer displays the F06 E02 error code.

Diagnostic Steps and Possible Solution

For the following steps, you need a Multimeter to help detect a breach in continuity. It would help if you learned how to use a multimeter. The improper use of the multimeter can fail to detect or cause more problems in the washing machine panel. Hence it is crucial to know your way around this equipment.

Here are the diagnostic steps involved in this possible reason:

  • Disconnect the washing machine from the power source.
  • Your multimeter should be in continuity testing mode or at least ohms of resistance.
  • Check for continuity between the U17 of the CCU and the C2 of the UI to test the current between the two units.
  • If the voltage reading is not up to 5V, you should replace the User Interface.
  • Also, check for faulty or damaged connectors between the two units and replace any cable with issues.

Faulty Central Control Board or User Interface

Suppose the diagnostic test above does not detect any error. Or perhaps you have replaced all the connecting cables, and the error persists. In that case, your whirlpool washer probably has a defective CCU or UI unit. 

If the wires connecting the units are working just fine, then the error lies with the control boards. However, since this diagnosis involves a crucial component of your washer, you’ll want to be sure that your previous diagnoses are correct.

Therefore, if you are not sure about the findings of your diagnosis, you might want to have an expert inspect the system. Sometimes, experts can detect cable errors that you missed. Then you can apply the proper solution.

Other times, the expert diagnosis may not detect any issue with the continuity cables, confirming your earlier diagnostic findings.

Possible Fix to Faulty UI or CCU

The only solution here is to replace the board of one or both units. Sometimes, changing the CCU removes the error indicating that the UI panel is functional. In other situations, you’ll need to replace both boards to clear the error.

Here are the simple steps involved in replacing the Central Control Unit:

  • Unscrew the top panel to reveal the CCU board at the top rear corner of the washer.
  • Release the control board locking arm and pull the board to remove it.
  • Open the wire covers, and disconnect them, noting the wire orientation.
  • Disconnect the old board.
  • Install the new board connecting the cables to the right terminal and cover the wires.
  • Reattach the board to its place and slide it in to confirm the lock.
  • Cover the washer with the top panel and put the screws in place.

You should also replace the User Interface board if the problem lies with it.

Here is a model video that shows how to replace the UI board of a Top Load Whirlpool Washer:

Can Motor Control Unit Faults Display the F06 E02 Error Code?

Yes. In rare cases, an error with the Motor Control Unit can also display the F06 E02 error code. In this situation, replacing the CCU and the UI might not solve the problem. Checking the connection between the CCU and the MCU or replacing the MCU, though simple, might be the solution to erasing the code.

The F06 E01 error code implies a communication breakdown between the motor control and central control units. Note that the three boards have close connections. Thus, the errors tend to overlap since the CCU is at the main of this 3-way connection.

So, an F06 E02 error might require you to check the MCU connections for mistakes. In the same way, an F06 E01 error might also require checking the connection between the CCU and the UI. The boards connect; hence, it is crucial to be thorough in your search.

Here is a table showing some common Whirlpool washer error codes and their corresponding meaning:

Error CodesMeaning
F06 E01Communication error between the CCU and the MCU.
F06 E02Communication error from the UI to the CCU.
F06 E03Communication error from the CCU to the UI.
