Hi,
Got Miele washing machine to repair..
Motor doesn't spin.. after some time got F53 error.. (Motor / Tacho fault) but its not even trying to spin it.. Motor is 3phase.
On board is Full H-Bridge for it and big capacitor.. Capacitor charges but Mosfets are not driven not seen any voltages on gates..
Mosfet driver is IR21363S..
No burn marks or anything on board that can be seen..
Also strange is that cant open doors.. always say Door Locked..
Any thought about it?
