MHN33 F70 Solution with Boards

If you have a Maytag MHN33 washer, have you noticed an F70 error that won't clear?
It is a communications error between the UI board and the CCU board.
In the past you swap the UI board and everything would be fine.
So you do that again thinking it is an easy fix, only to find when you do that the F70 still doesn't clear.
Why?
See the tech tip below and check your model and serial numbers. 
You might need to replace both the UI and CCU at the same time so they talk to each other correctly, or you can get away with just the UI board.
Frustrating? Yes! At least now you know.
Order some kits before your parts warranty runs out!
