I need help about BRAUN FOOD PROCESSOR type:4262

Hello all.
I have a BRAUN FOOD PROCESSOR type 4262.
In the PCB of this device destroyed an electronic part that not showing any evidence on it and the manufacturing company that I sent email did not give me any access to the damaged part or electronic schematic of the PCB.
(The strange thing is that PCB is discontinue in the market from the company) :redsad:

This damaged part has the function to regulate the speed of the one pole of the 220V(?) DC motor.
The other pole controlled with a TRIAC (BAT12)
Any ideas?

(Sorry but my English is not good)
