I have seen other posts regarding the F70/71 code that people have gotten but none have been sufficient to solve my problem. HELP!!!
After 6 years of very few problems(except for drive motor replaced) The washer quit and gave an F70 code. The door lock would not click and lock. A tech came out and looked at it and said that he thought that the door latch was bad. Put new door latch in . it worked for 1 load then F70 code. He came out again thinking the MCU might be bad. He took one off of another "good ? Used unit" that he had at the shop, and tried it but that didn't solve problem either. ( I don't know if he did the "remove plug w/3blue wires on the MCU test" that you spoke of in another post or not?) You may be confused at this point because I know I am. He then said that it might be the CCU so I took a chance and found one on eBay . I installed that one myself and it worked for 1more load then f70 again. About the only thing that has not been replaced is the User Interface boards. I personally think that the UI should have been tried first. Because in the service document I found behind the front panel states that with F70/71 code as long as the drum can be rotated (which mine did move) then the UI board should be replaced.
I have put so much time and money in this thing, I am afraid to throw any more money at it. What is your opinion on this.
FYI, I tested every wire with my ohm meter and all the wires and connectors that are related to the MCU, CCU ,UI , water valves, heater element etc. all checked ok. I also tugged and wiggled them to see if there was any change in the readings. Also sprayed connectors with electronic contact cleaner.
Thanks in advance
Mike. Let me know if you need further clarification on any thing .
