The heat fuse (white component 'Y51 H 120...' next to the blue wire) is of the type: 120 degrees Celcius, 3 Amperes and it handles 250VAC

Check the heat fuse by measuring the resistance over the heat fuse, it should be very close to 0(mine was 0.03 ohm) if it's working. NOTE: even though it's resistance is 0 it could still be the close to broken. When current current passes through it might build up resistance.

My motor did spin with 12v applied directly to it's poles(though not very fast). The fault of my machine was that the heat fuse had "blown off" after replacement it worked perfectly again!

The DC motor is specified to 230v and is of a brushed type.
