Indesit WD10 strong burning odor when drying?

Washing machine: Indesit WD10

This is very recent. I have owned the washing machine for about two years. I have not run the washing machine since the strong burning odor because of fear that it might burst into flames.

I suspect that a sock or small piece of material has become caught up somewhere. Any suggestions of how to check for the cause of this problem?

Thanks.
