I'd call your reseller or contact UM directly for support.  At the top of this page on the right click the 9 dots icon, then click "support".  Then near the top click "submit a request".

 

Alternatively you could look over this guides:

If you follow those steps and then examine the filament detector carefully you might notice something e.g. a wire fell off.

 

But really, contact support.  They know this stuff really well and I don't have a MS so I have no clue.  Even if you are out of warranty, support is free.  It's only if you need parts and also out of warranty that you will have to pay for something.
