Indesit WIDL 126S EX problem

Hello !

I have a strange problem with a Indesit WIDL 126S EX. In the begining, the problem it started with a rapid blinking of the four lights situated on the top of the panel + the bottom light in the left part of the panel. The lights were blinking fast as the door lock light blink and that was all.Nothing else happend.
I fixed the blinking by changing the 22uF/400V polarized capacitor from the power supply of the board.
Now, when I try to start the washing machine, all the lights go lid like a reset sequence, then all of them go off (including the door lock light) and nothing else happens.
What can it be and how can I fix it ?
Thanks !
