Hmm, not sure that musak is any better.
First of all we need the full serial number and any other numbers from the label down the side of the door. As mentioned above there are two totally different control systems used on these, sadly both of them are rather poor.
I also noticed on your video that some of the buttons appear to have been pressed in a bit, they are touch buttons, not push buttons. Being a bit heavy handed with the buttons can damage the PCB.
If you have access to a megger or suitable multimeter then the first thing to do after removing the mains plug is to test the main motor and heater for low insulation.
If they are fine then it points to either the display PCB or the main power PCB on the later model. Display PCB is most likely but you never know with these Indesit made machines.
That which can be asserted without evidence, can be dismissed without evidence.
