Based on your different setup, a holding tank in the wetlocker space, it may that the tank is somehow compressing the water inlet hose.
I have a small fiberscope from Aliexpress to look in all sorts of inaccessible spaces. Brilliant tool to have on a boat.
On my 335 the 36L holding tank has move to the forward part op the starboard couch.
Hi, Thanks for the suggestion. Yesterday evening I was to access the water pipe which I found runs to the left hand side of my holding tank. I removed the jubilee clips and found the lower smaller diameter pipe completely blocked with a white substance. The 90 degree bend into the water tank was also blocked in the same way This could be calcium or more likely an accumulation of water treatment powder that did not dissolve (over the years?). Cleaning both out should solve the problem, finally.
Many thanks to everyone who contributed to solving this problem.
