E1F1 Error On Whirlpool Washer

E1F1 Error On Whirlpool Washer [How Did I Fix]

Whirlpool washers have an error code system that helps you diagnose and solve the problem. If you have a bad pump motor, a faulty control board, or a defective door, you can perform diagnostic tests and fix the error on the whirlpool washer. 

Some error codes will need you to reset the whirlpool washer. Others are challenging and require you to either fix them or call a service technician. The good news is E1F1 error code is easy to fix. This article will explain the code’s meaning, what causes it, and how you can fix it.

What Does E1F1 Error on My Whirlpool Washer Mean?

An e1f1 error code signals an issue with the appliance control unit (ACU). The problem arises because of wiring/connections or damage to the ACU, which is the brain of the whirlpool washer, and it controls everything. Any damage to its component will affect the washer’s performance. Therefore the EFI error means you need to perform diagnostic tests to fix it. Otherwise, your washer will be useless, and it won’t work.

A word of caution: don’t confuse this error with the FO1 error. In other whirlpool washers, this error means a communication error or failure of the drain pump. Make sure to double-check the error before running a diagnostic test. 

Before you fix that, you need to reset a whirlpool washer. The best way to reset the machine is to disconnect it from the power source. Resetting works by allowing the electrical charge to dissipate from the washer. 

If it fails, try again, but this time, increase the amount of time you have to wait. To avoid damaging the washer, ensure the washing machine is turned off at the control panel before unplugging it. Here is the process you need to follow:

  • Turn the power to the washer on at the wall, but the power button on the control panel is off.
  • Hold the button down while pressing the water level button two times. Expect the control panel lights to illuminate.
  • Press all the control panel buttons one by one except the power buttons.
  • Open the washer’s lid, and you’ll hear it beep.
  • Close the washer’s lid, and it should begin to cycle.

If this process doesn’t work, you’ll need to perform diagnostic tests to find out the cause. Check out other errors that may affect your Whilrpool washer.

E1F1 Error on Whirlpool Washer: Causes and Solution

Inadequate voltage

If your washer’s voltage is not within the desired level, error E1FI will occur since the ACU can’t operate with an inappropriate voltage. A drop in voltage or a surge can trigger an E1FI error. Ensure that the electrical outlet is in the 110-120v voltage range for your washer.

Besides that, a damaged power and or loose power plug will disrupt the electrical transmission triggering an E1FI error. That means the ACU won’t receive power to function properly. Therefore, it’s necessary that you look at the electrical connectivity and wiring and plugs to ensure that things are working well.

Defective Central Control Unit/Central Control Board (CCU)

The CCU is the brain of the washer. It houses so many components that can be corrupted with time. For instance, CCU wire harness connections can be damaged or loose, leading to a slight imbalance in the power supply to the ACU. And this can cause the E1FI error code to display on the screen.

False Alarm

A false alarm won’t necessarily originate from CCU, but it will come from other washer parts that can trigger the EFI error code. For instance, a damaged drain pump or a poorly connected one can be misinterpreted as an ACU fault. And you’ll likely spot this scenario when the washer stops working. In this case, the washer will show or display an E1F1 error once the drain cycle begins since it’s the part where the drain pump has to work properly.

The same error can also happen when the interference filter is damaged or loose. In other words, don’t be quick to rule the E1FI error code being associated with ACU alone.

How to Fix the Error E1F1 On Whirlpool Washer

Check to see if the washer’s getting enough voltage. Inspect the damaged code or loose power outlet. Your washer needs to be on a dedicated circuit to work properly. The voltage present at the circuit and outlet needs to fall at the correct range for the washer to work. Assuming that the voltage is correct, you’ll need to reset the washer and start a cycle again.

To fix a faulty ACU, you’ll need to gain access to the top panel and another electronic outlet. Once you have opened the top panel, check if all the connections to the interference filter are secured and working okay. There should be no wire that’s detached. When checking the ACU, ensure that all its connectors and internal pins are visible and the green wires are in good working conditions.

The internal connectors have to be sealed and secured. If you find any damaged connectors or wires, you’ll have to replace them immediately. Also, ensure that the two ground switches at the toe and rear panels are positioned well.

If the error persists, you’ll check the line voltage of the interference filters and ACU. A  word of caution: inspecting this line can be dangerous unless you know how to do it safely. To be safe, you’ll have to call a repair technician/

The voltage line should be at the input and output of both the ACU and interference filter, and the error will disappear. That means you’ll need to replace the part if any of them is missing. Once you have repaired and replaced all the parts, you may need to reset the washer again and start the cycle to ensure there’s no error.


E1FI error code shouldn’t stress you. With these instructions we have covered in this article, you should be able to clear the E1F1 code. After clearing the error, make sure you reset the washer. 

If you still find it a challenger, it’s better to call a technician to help you repair it. Also, consider subscribing to appliance extended service plans if your Whirlpool washer constantly gives you a problem. Let me know if you managed to fix the error code.
