LG Washer/Dryer Power Fail

Re: LG Washer/Dryer Power Fail

Your module is faulty, it has three phases for powering the motor and two of its phases are broken, there is a short circuit on three IGBT transistors.

Ok, thanks for the answer!

I'll try to reconnect the washing machine without the motor driver to see if the machine turns on.

I did a few tests earlier, put everything back in place (TOP246 and other components removed for testing) then plugged everything back in.
Result: Nothing happens when I press the button on the machine (although I'm not really sure, perhaps a relay has been activated).

In a nutshell:
The initial problem was that the power resistor linked to the ignition burned immediately when the Power button was pressed.
After removing the motor driver, it turned out to be short-circuited.
I repeated the test without the driver fitted, and nothing happened.

Maybe the TOP246 didn't really appreciate it and should be changed.

What can you deduce from this?

Thanks for your advice.
