Dishwasher Neff S4453 (aka Bosch sgs5302??) not starting - NO POWER?

I've discovered by removing the top screws from he inside of the dishwasher, the front panel module can be removed, and it is this that appears to be faulty. However, the guy from the service centre said a replacement module is about £120-130. Isn't this a bit expensive?. What can go wrong with those modules?.
