F-28 error code

I am getting the F-28 error code about 50 percent of the time. when i start a new wash cycle, it will make it all the way to the rinse cycle before i get the code. Sometimes there are 25 minute to go and sometimes less. I just turn the machine off and restart the load and half the time it works and i do not get the code. I think it is getting worse over time. Thanks

My MCU is relatively new (a few months ago) and now I occasionally get the F-28 error and I can’t figure out what affects it.

Did you every solve this problem?
