Error code E02 and F01.

According to https://www.justanswer.com/appliance/7w4q8-f01-e02-error-code-showing-whirlpool-front.html, it indicates that the controller isn't getting readings from drum tachometer. Could possibly be loose wire. Replacement parts said to be $200, so may not be worth buying.

you might be able to sell to someone willing to diagnose & fix.

F20 water only problem insufficient water supply open both hot and cold unclog hoses
F21 Drain problem clogged,frozen kinked
SUD excess sud using non he detergent or to much detergent
F22 front door lock door not closed properly
For these select poepwer/cancel twice to cancel cycle
Other f codes select power/cancel twice select drain& spin if youhave excess water

f06 OR e02 error code means you have an interface communication error. the main control board isn't communicating with the front interface control board. if you pull the washer out and remove the 3 screws coming in from the back of the top panel. the top panel will pull straight back, up, and off. check all the wire connections between the two control board and make sure they are all secure. if everything looks good, then the interface control board may need to be replaced.
f01 e02 means that your motor control board is not reading the tachometer on your motor when it tries to turn the motor. it thinks that the motor is struggling. open the door and turn the basket to make sure it spins freely.

First check all connections between the mcu and the ccu, remove the top cover by removing the two screws in the rear of the top cover pull and remove. If after checking and still the same, you might want to also Check the motor for the correct ohms. You might need to have a service tech to come out.

For how long did you unplug the power cord? If it was under 5 minutes, unplug it for longer. Check if that clears the error code. If it doesn't, the motor control unit needs to be replaced.

Please double check your model number to get the correct part. Most of the Whirlpool washers have model numbers that start with 3 letters.

I hope this helps.

Great! you have the MCU (motor control unit) need to replace. Removing the rear panel so you are able to see the motor and MCU. Replacement is easy, almost no screw on the board.

Tip the machine up & look inside up high, you
should find a bag with the diagnostic service
manual & it has the codes

Whirlpool Duet Washer model number WFW94HEW2

My wife put a bunch of wet towels in the washer after this we got Codes F01 E02. I freaked out.
Under the top(roof) panel of machine there is was a service technicians manual that explain how to enter Service Diagnostic mode and explained fault/error codes and their possible causes. This isnt for the faint among us. But if you can solder and work with electronics you can diagnose the problem. The technician manual tells you check this, then this and if that doesn't work/ or does work go to 'C', then go to 'D' etc. Either way I ended up diagnosing that it was my MCU (motor control Unit), you did have to use my multi-meter, for ohms and resistance, but it wasn't rocket science. Upon close observation there was a burnt connection solder point on the board. I looked up the part online and ordered, wasn't cheap. $225.00. But just to come diagnose the machine Whirlpool was going to charge $100.00 + parts and whatever else. The moral of the story is if you can tinker and be careful you can totally do this.

Hi there, After about year and half Whirlpool duet sport gave F01 error code. The technician manual is located under the lower front panel. There are three possible reasons for F0: 1) EEPROM ERROOR. Unplug a washer for two minutes. Try running it again. (Did not work for me). 2) MAIN RELAYS ERROR. The tech manual suggests replacing CCU. The following is what I did and it fixed the problem, however. Unplug the washer. Remove the top cover by removing the three screws on the back. The CCU unit is in the right bottom corner if standing in front of the washer – it has a lot of wiring. Plug in the unit. While listening to the CCU start any washing cycle. After pressing START you should hear the relay to click. If it clicks twice, within a less than a second, it has a problem. Unplug the washer. Without disconnecting any wires remove the CCU cage from the washer wall. Stand now on the right hand side of the washer in such way that the CCU cage is under your left hand. Pull the right upper corner of the CCU plastic cage (it has a tab) away from you, slide the cage to the right by about an inch, and pull the entire cage away from you. Now knock on the back side of the cage 4-5 times with a bit of force (watch “Armageddon” movie for more instructions on it). Install the CCU cage back. Plug in the unit. Try some washing cycle again. If it did not help, repeat the procedure. If it did not work again, see the following. 3) PUMP DRIVE ERROR. The tech manual suggests replacing CCU.
