Electrolux ERL6298XX12 Side by Side

Hi all, not seen any of these Electrolux side by sides so just wanted to see if anyone could point me in the right direction. The fault was that it kept dispensing water randomly or at least this is what the customer reported. I have been out and found it to be letting water out through the wrong valves when dispensers pressed so have changed the valve. There is now no power to the valves at all so not sure where to look next or if this is a control board issue and if so likely to be the front or back. Any help is much appreciated.
