Hi dear,
Seems like your washer has bearing seal damage. It will be expensive repair. You may contact Miele to get a quote. Thanks.

Did you ever find an answer to this?

If the Start LED keeps flashing, either the door is not closed properly, or the door switch is broken.

I have today purchased a Miele 3985 machine with a know F50 Fault code appearing

Before I went to the expense of calling a Miele technician, I explored the blocked / clogged drain path

I removed the drain pipe and noticed there was a lot of 'residue' / gunk in there

I cleaned what I could, and blew through the pipe back into the machine

Then I did a cotton wash cycle at 90degrees, with a 1litre of bleach to clean the drain path

The wash looked extremely dirty during the cycle

It appears that this resolved the F50 fault code issue with my Miele 3985 Navitronic

For our model Alemnesh's suggestions were spot-on. It's hard to believe that a machine with such a good reputation would (a) allow this fault to occur so easily and (b) not have its own manual provide explicit guidance as to how to fix it.
