Verlauf von "stops with an F 51 on the time display" bearbeiten

I have tightened this nut three different times. Each time it will work properly for about a dozen loads and then the F51 error code appears again.  And yes, I am careful to do only small loads.  Does anyone else have this as an ongoing problem?  Is there a part I should replace instead of continuing to keep with this temporary fix?
