This is an unknown make here in North America. This link may work better for you. Errors that stop washes are generally cause by a lid lock that isn't working, or a drain pump that isn't passing self test. If it works and then throws the error DURING a wash, it is likely to be the 'out of balance' error.

This is a clutch problem.
Or the agitator just need tightening down. Remove the stuff from the top and down inside you will see a deep seated bolt. Tighten it.
'make model (what it is)' in all questions please.
Then you can Google
make model REMOVE agitator
And then do the reverse!

Ah, 'MD Start' is the NAME of the maker of a Medical washer, nothing to do with Metal Detecting, one of my other fields of expertise!
Contact them direct, as this is not a consumer appliance, and they are based in Paris and we are in North America.
