Machine Stopped at end of rinse cycle.
Error Code F6 E1 displayed when we try to start up with a new cycle.
"Communication error between the CCU and MCU.
Washer won’t Activate Diagnostic Mode, with method Service Manual Describes. User Interface lights up otherwise, just no response at all when performing the press release method with the three buttons. All three buttons work when cycle mode is selected.
Went through TEST #1 to check out the CCU, steps 1…10
Went througt Test #3 to check out the MCU, tests passed up to 11…12, which I couldn’t perform step #11-12 because the "Diagostics Mode" isn’t working.
I am thinking the CCU is faulty, even thought it passed the basic CCU tests indicated in the manual.
Help!
