Indesit IWME126 Possible control board fault

Hi.
I have an Indesit washing machine that stopped during a wash cycle. I removed the top cover (after replacing the fuse, which didn’t fix it), and found quite a bit of condensation. I had already un-plugged it. I had a look at where the power cord entered the machine and saw that it too was rather damp and contsisted of more than just a connector. So I removed and dried it using compressed air. I should at this point say that I am fairly competent with electrics although I am by no means an expert. After reinstalling the cord unit the machine would still not turn on. No lights or noises when pressing the power button. So I un-plugged it again and followed the wiring down to the control board. On inspecting this I found that it too was damp. I removed and inspected this and saw a burnt area and it had the dreaded electronic burnout smell. I dried it out and re-tried it but to no avail.
Upon searching the internet I came across a couple of sites selling a replacement, but one of them states it as “Unprogrammed”. My question is : If I buy a replacement, will it require programming by an engineer? Or will it work when plugged in?
Espares list it as the following:
Indesit Washing Machine Arcadia Module (Not Programmed) for IWME126UK Price:£83.25 Stock Number: ES1062995
Manufactured by Indesit Part No. C00252878

Any advice would be gratefully received.
