how do i replace the componnent controller on my servis 1100RPM washing mac?

As above.... all I need to know is can i just unclick the old commponnent which ive already done! with power off of course1...and i'm looing to find a good new replacement commponent... i know what happened to the machine itself...as i blew it up! no mystery there... i blew its brains out by switching the dial mid very fast spin stream... and thereby confusing the brains of the machine and blowing it up...there was a loud bang and a bright flash...as the commponent expolded, and the machine stopped... the light was still on but it wont work as i have blown it's mind.. I dont want to spend a fotune on a repair man to simply click in a new part... and it is all plumbed in and ready to use...unlike a new machine these days which are all cold fill only makes...so id have to shut off the hot water supply etc etc... SO I JUST WANT SOME HEALTHY GOOD ADVICE ON THIS REPLACEMENT WORK...WHICH I INTEND TO DO MYSELF..!! THANK YOUNFOR ANY HELP YOU MAY HAVE TO OFFER ME ON THIS SUBJECT...
