So we have a repeating F71 communication error between ccu & user interface. We have already replace the ccu, user interface boards, & the harness connecting the two. Twice. And now we are getting an F70 a communication error between the same boards. Is there anything else we missed? Could the motor control be causing this as well as I know there is separate error codes for this as well. Any ideas will be appreciated.

90% I find that the MCU is the cause for this...try unplugging the 3 blue wire harness connector from the MCU...if the unit responds normally (except motor function of course) this is it.

I've had 2 in the last week that needed the MCU for the same issue, fixed them both.

Thanks guys. Had a feeling it might be. Was thrown off by the fact that the washer worked for a few weeks after replacing the UIB & ccu. Again thanks
