Hi

Error code F70 means Control Unit Failure, no communication is detected between the control board & interface. You'll need to use a multimeter to check for the continuity between the Keypad and the control board. Inspect the wiring between the boards. Also check for any burnt component on the control board. You may need to replace the control board or user interface. To be sure whether the boards use a multimeter. Usually if the drum moves then user interface is bad else its the control board. hope this helps...

Amana front load washer model num NFW7500VW00 CODE F70 WONT COME ON OR START


I have had a good look around and this seems to be a common problem with Maytag Amana etc machines.
Trying search Maytag f70 code and you will see.
It seems to be a faulty Control unit. Cause number 4 below seems to be what you have.

Here is one answer from a tech guy.

"The "F70" error code is indicating a loss of communication between the Central Control Unit (CCU) and the user's interface board on the right hand side of the console. The main top can be taken off by removing the screws along the back edge of the top. NOTE: Disconnect the power cord from the power source before removing the top.
Possible Causes/Procedure:
1.Check for continuity of the user interface harness
2.Check the wire harness connections at the user interface board and the Central Control Unit.
3.If the unit will run and rotate before the "F70" displays usually indicates the user interface board will need to be replaced.
4.If the unit will not run and rotate usually indicates the Central Control Unit will need to be replaced.
if you feel you cant do this you will need a technician to come and look at this. "

F21 error on model mhwe300vw13 maytag 3000 it


Hello & Welcome to FixYa

F21 error is displayed when the washer is unable to drain, press PAUSE/CANCEL button twice to clear the display. After this please check the drain hose and drain pump filter for any blockages and make sure it is not clogged with foreign particles. You can also check the drain pump to verify that its working. Please get back to me if you have any other questions.

I have a Kenmore model 11049962603 that displayed an f-71 error code. I ordered a new cpu computer from sears and installed it. the machine seemed to work for one or two loads. now it displays an f-70...


I provided a complete list of error codes for this type of washer in the image below. The error codes vary by the exact model of HE3t washer that you have. Since you have an HE3t that is displaying the F70 and F71 codes, the list below should apply to your model. These are not listed in the owner's manual because they are intended for technicians. Use extreme caution if you follow any of the troubleshooting described in this information sheet. Unplug the washer and shut off the water supply before accessing internal components.

The F70 and F71 codes indicate that you have a communication error between the CCU (Central Control Unit or main machine control board) and the user interface touch pad assembly. Here are some troubleshooting tips:

Make sure that you have the washer plugged into a properly grounded 3 prong 120 volt AC electrical outlet.

Unplug the washer for 30 seconds to allow the control boards to power down and reset. Plug the washer back in but do not touch the power button (or any other buttons) for 1 full minute. This may reset the control board. Pressing the power button too quickly after reapplying electrical power to the washer can cause the F70 or F71 code since the CCU does not have time to recognize the user interface control.

If the above tip does not help then the most suspect component failure is the MCU (motor control unit -- motor control board at the bottom of the washer beside the drive motor). You can check for this failure by unplugging the washer and then pulling the MI3 connection on the CCU. The wiring diagram below has the MI3 connection highlighted in red. The connection has blue wires. The third image below shows this connection on the control board. The connections are labeled on the control board. Press the tab at the bottom of this plug down and then pull it out. Power up the machine with this connection unplugged and don't touch any buttons for 1 minute. If you then press the power button to turn on the washer and don't get the F70 or F71 code then the MCU at the bottom of the washer will likely need to be replaced to fix this problem. A technician would normally be needed to verify this failure and replace the MCU. The MCU is expensive ($423).

This troubleshooting information is based on a common HE3t model that displays the F70 and F71 codes. If you need more help, submit additional details and the full model number of your HE3t washer.

Same problem but I have a 3 week old maytag 9000 steam dryer, ran for a few minutes then turns off and display reads F 70


From everything I have read on the F70 code (can't seem to find an exact explanation of what it is) It seems like people are getting replacement dryers due to a electrical problem within the dryer control circuitry. Since it is only 3 weeks old, get it replaced. Good luck
