A Whirlpool washer error code E01/F06 indicates that the washer’s motor control unit (MCU) is having trouble communicating with the washer’s central control unit (CCU). In most cases, the issue is caused by a damaged MCU circuit, usually caused by an overload. If you heard an electrical popping sound when the washer stopped working, the MCU (or CCU) likely needs to be replaced. However, in some cases, the error code may just be a glitch, which is fixable by resetting the washer (disconnecting the power).
Follow the steps below to diagnose and resolve the E01/F06 error code.

If your Whirlpool washer has an E01/F06 error code, the first thing to try is to reset the washer by disconnecting it from the power for 10 minutes. After you reconnect the electricity, if you do not see the error code, you can run a quick test using the washer’s diagnostic mode to make sure the error has been resolved.
Follow these steps to reset the washer:
The next three steps will require accessing the CCU and MCU. With most Whirlpool washers, you will need to remove the top of the washer to access the CCU and the washer’s rear panel to access the MCU.
The tools required can vary depending on the model, but with most Whirlpool washers, you will require a 1/4 inch socket or nut driver and a small slotted (flathead) screwdriver.
Both the top and rear panel should be secured with screws, which you should remove with the relevant screwdriver.
Make sure to disconnect the power to the washer before removing the access panels. For safety, the water to the washer should be turned off as well. To protect against cuts and electric shocks, it is recommended that you wear appliance repair work gloves.
With most Whirlpool washer models, the CCU is located at the top of the washer, in the front right corner. The MCU is usually located at the bottom of the washer, in the back right corner (when facing the front of the washer). Both components will be housed inside an assembly that is secured to the side of the washer.
Once you have located the CCU and MCU, check that all the wires are securely connected to the CCU and MCU. Follow the instructions below to access the MCU and CCU assemblies. If you find that a wire is not connected, plugging it in should resolve the E01/F06 error code.
In most cases, damage to the MCU is responsible for the E01/F06 error code. Once you have located the MCU, inspect the board for signs of burning or damaged wires. If there are burn marks or the MCU is damaged, replacing the MCU with a new one should resolve the E01/F06 error.
Follow these steps to remove and replace the MCU:
The MCU can be tested with a multimeter. However, testing the MCU with a multimeter is best left to a trained technician, as the wiring may differ depending on the model, and the washer’s power may need to be turned on, which increases the risk of electrocution.
If the MCU is in good condition and not defective, the error may be caused by the CCU. Like the MCU, the CCU is difficult to test with a multimeter, and so it is best to get a trained technician to check it. However, like the MCU, you can inspect the CCU for signs of burning or damaged wires. If you notice burn marks or damage, replacing the CCU with a new one should resolve the E01/F06 error code. Replacing the CUU can be expensive, so again, it is best to get it checked by a trained technician before replacing it.
Follow these steps to check and replace the CCU:
CCU and MCU issues are some of the more difficult appliance repairs to perform, especially without washer repair training. If you have followed the steps above and the E01/F06 error code remains, it is time to call a trained technician.
