Excellent video. That was the problem. It didn't take long to fix.

I have Kenmore version of this one. It was manufactured in 2008. I also got F71 error. I tried some of the other simple fixes that others have suggested, then I disconnected the water supply and found that the small wire mesh filters (hot and cold supply) at the connection were clogged with scrunge and debris. I cleaned them and no longer have F71. Worth a try before you call the repair guy.

Scott, very informative and helpful video. I had been troubleshooting my Whirlpool washer WFW9500 with an F70 error code and could not figure it out. I unplugged to motor control wiring (blue wires at the top of the module) and was able to get the washer to turn on. The motor control unit connector was wet. I am waiting for it to dry up... update to come. Thanks a lot!

Great video. This will help you to determine if the Motor Control Unit is bad: "To determine the cause of the problem you will need to unplug the washer for 30 seconds then plug the washer back in. Wait 1 minute before you try to power the unit up. If the washer will not power up, unplug the washer again and access the motor control board. The motor control board is located in the bottom portion of the washer. Now remove the connector with the three blue wires. Leave the connector disconnected, plug the washer back in. Wait 1 minute, and push the power button. If the washer powers up you need to replace the Motor Control Unit. If the washer still will not power up check all of the connections on the main control board located under the top of the washer. The cause could be a control board or just a broken wire in the harness." After unplugging my 3 blue wire harness & plugging my washer back in, it powered back up despite NOT powering up with the 3 blue wire harness plugged in. This is a MCU issue.

Decent video. 4 outta 5 stars. Camera angles didn't fully show how to remove the motor control board, but SUPER knowledgeable.

Do not be upset. I will share my fix :( Wife get upset and force me to knee and open the bottom cover of the washer and remove motor control board (i watched vid on youtube to learn how to) :) In my case i had a f70/f71 for over 6-9 months hoping that it will go away somehow miraculously. It would start and stop before spinning, beep and do not start at all, lock the door etc i did a lot of unplugging. Wife said: enough !!!!!!! back to motor board. im looking at the board and see "communication" circuit from the computer is separated from the rest of the board with two Optocouplers TCLT1103. I looked at it close with magnifying glass x10 and see a bit of tiny residue between 3 legs. Cleaned it with needle/spirit/brush. Put everything back together and now it looks as it is finishing the whole cycle. it looks like this tiny residue was giving problem to the transistor side (reading side) of TCLT1103 Optocoupler and could not communicate properly with the main computer. Somebody is going to hate me !!!!!!

Did it work is the question no video on KZfaq shows it working after

Mahalo for the video

Scott, The F70 error code came up at the end of several codes C:00 U:22 2:22... ten codes in all then the F70 code came up, I unplugged the blue wire on the MCU and my washer stayed the same buttons just dinged. Model WFW9550WW10 What would be the next to check in this case. Thanks for the video

This might be a dumb question... but where do you suggest I buy the motor control unit??? I have what appears to be the exact same Kenmore Elite model shown. Thanks in advance!!!

How much do suggest I pay to have this fixed and the water drain cleaned?

Do you know the part #?

Replaced the MCU as described, and still code 71. Any suggestions?

I’ve had the error code F70 for a few days now. For a while the power would not come on. Now it is F71. Is this normal? The drum does, or did rotate. So according to the TS guide it is a user interface problem.

my maytag itmaking the same sound but i have already tried taking out the blue wire it still didnt come on. but the washed does work ever now and then.

I did all of that and when I turned it on - still not working. F71 again. Any ideas?

What else could the cause be if after disconnecting the 3 blue wire plug the f71 error persists? I also checked voltage and I get 5 volts for the blue wire connector

Hi was wondering if after you disconnect the blue wire and go to try to start it it start but comes up with a f28 code...after plus blue wire back in does it mean it still a bad MCU

Why can't i find anything about error code f73
