My grinder motor burned stuck. New motor assembly installed not workin

My grinder got stuck and burned out. I can see from outside the motor all the wires burned inside. I bought a new motor assembly (with cables and everything) and did a swap. Now new grinder does not move at all , The machine does full coffee preparing process but only water comes out.

Can this be the same mosfet burnt that makes the grinder run forever or should i look for something else?
