Hey gang,

I'm puzzled by this one. My washer showed F70 code. Initially it cleared and I was able to watch the machine start a cycle. Drum rotated, cycle worked normally but then stopped partway through the process. It then died completely...beeps 3 times when power button is pressed. Went through the troubleshooting steps and everything checked out on the wiring, etc. Seemed to indicate the user interface. Replaced that...same behavior. Replaced the CCU...same behavior. Found thread on this site saying to remove the blue wire harness to the motor control unit. Sure enough with that disconnected, machine powers up and acts like it's going to run. Replaced motor control unit...sigh...same behavior. Still just getting the 3 beeps as long as everything is connected up. Remove the blue wire harness on motor control unit and the machine powers up. Any help would be greatly appreciated. (By the way, full disclosure, I replaced each of these units with used parts purchased off ebay.)

Thanks.

Can you get your money back from the seller on ebay?

The problem is the MCU, every member here with this same F70 error code DID THIS SAME THING:

Found thread on this site saying to remove the blue wire harness to the motor control unit. Sure enough with that disconnected, machine powers up and acts like it's going to run.

And the new MCU they got through our parts supplier fixed it EVERYTIME.

Here's the MCU through our parts supplier you can order:

Consider that lesson learned. Thanks.

So, I went ahead and put my washer back together with all the original parts. Now it powers up even with the wire harness connected to the MCU. Have you seen this behavior?

Also, does it mean anything if the washer won't cycle through the diagnostic tests?

Thanks.

Yup, but trust me, it will happen again until you replace the MCU through our parts supplier.

Also, does it mean anything if the washer won't cycle through the diagnostic tests?

Yup, its likely the MCU causing that as well.
