Alternative control panel for washing machine Indesit

[anso-engineer]

Hello, I have washing machine Indesit WISN100, default control panel not suitable for me. I need some custom programs designed by myself, anyway it can be immitated via combinaion of different control panel commands.

I saw control panel has only 4 wires, so I suppose it works via specific interface together with upper control unit.
Can the signals from buttons can be decoded for the next processing via MCU?

Probably so, but you would have to reverse-engineer exactly what's required.

Is there any specific algorithm for this procedure? Probaly if there 4 wires, maybe two of them is power wires and rest is data wires?
I plan to firstly identify power wires and as next check the rest.

I've no idea, I've never been involved with washing machines - but apparently you can buy 'Universal' washing machine controllers.
