LG washing machine sound

[SteveAuditore]

Hello everyone, 

 

recently we bought a LG washing machine (F84G6TDM2N) and it makes chimy like sound when it completes a cycle. 

 

When I first heard it, I Immediately wondered if it can be changed to something else I upload to the washing machine. 

 

Do someone has a experience with something similar? Like breaking into similar software? 

 

Thanks for responses

Maybe? There's a chance there's a UART or JTAG debugging port on the control board. If the developers left it there and left the chip open, you might be able to modify the firmware. 

 

The hacky way to do it would be to desolder the buzzer and tie the buzzer to the input of a microcontroller. Whenever the pin goes high, you can have it start your own tone on your own buzzer. That's probably the way I would end up doing it because I'm more of a hardware guy and it would almost certainly be easier.
