'Faulty switch' is not actually faulty ? — Brushless Bosch GSR/GSB 12V repair

Hey guys, in this video we take a look at two Bosch sub-compact drill drivers.
Bosch GSR 12V-35 and GSB 12V-30 which are both brushless. They were both sent to a repair shop and neither of them came back fixed despite the trigger replacement.

Thanks for watching!

Tengo el gsb 12v 30. El motor se mueve un poco, pero deja de hacerlo. He revisado el mosfet de la imagen y no esta dañado y otros componentes, tambien el motor, no se que hacer. Tienes el esquemático de ese modelo?

I have gsr 12V 35 and occasionally the break do not engage after releasing the trigger ( and the drill is unresponsive until it stops). I send it to under warranty repair and they change the circuit board, but it still do the same thing. Any idea what this can be ?

My mosfet is bown the same way. The only option I have is to buy the whole board from Bosch for 20 EUR. Can you please share the specifications for the Mosfet, I can see the original is H7084 but the one you used is H7440. Can you please provide the part number?

Stupid bosch quality. I have the 12v35 had the sae issue sent it under warranty, got it back did the same thing. Sent it again in out of warranty, so far they have fixed it.

The same issue i have on 12v 15 hx but i am not willing to send it of to repair beacuse it costs me 30 eur. New one is 90 eur.
