Aqualisa Aquastream - Thermostatic (post 1997) Boost / On / Off

Hi, Have the above model there was cold water leaking for some 2 months, changed the Grey Cartridge, The shower works but the boost does not increase flow. Checked the mains and there is live power, however there is no live power in the shower unit on the loom white connecter. If there is not live power into the loom could it be the Transformer ? How do i check if the transformer is working or not ? Thanks

A leaking cartridge is the usual cause for the loom to fail and if you have not replaced it I would do that now.
