Sussed it. I removed the 1/2" cartridges and when I looked at the mechanism the bottom wasn't turned as I turned supply on so the cold wasn't flowing at all. Ordered new part and should be sorted asap. Thanks for the info for future reference.

I have been trying to repair the Trevi Therm shower I have at home. The shower only provides water when the temp control is above the 40°C temp override setting. If the temp is turned below that setting water ceases to flow. I have removed the thermostatic cartridge, which was silted...
