Yes, is the water going in and out of the coil?

Anywhere the magnet attracts, (and especially where it sticks), is likely to be badly blocked up with iron oxide, which will be impeding the flow of water and preventing normal circulation. Afraid, as previously stated, the only solution is to cut the affected section out and replace it. No amount of cleaner will break up that type of blockage unfortunately.
The X100 is inhibitor, used to prevent corrosion within the system. Has the system been drained since this was added do you know?
Turn on the hot water and turn off the heating, then let us know what happens after 1 hr.

That suggests the valve is stuck on CH. Could be sticking mechanically or perhaps the microswitch in the head is stuck or the return spring in the head is broken.there is no springiness or want to return of the pin
update, i did the magnet test again, and at the part of the pipe i've indicated in poss-block.jpg image, the magnet pulls, infact the magnet holds there, this is before it reaches the bend to come back down and into the cylinder, at entrance into cylinder it feels cold, also the out from the cylinder feels cold and gets warmer the as it disapears under the floor of the cupbload (pic above with red valve), i have the pump on 3 for a bit, in the hope extra flow might move any debris, but i think im screwed.
Robert ,set programmer to hot water only ,unlatch the 3 port valve and it should slowly move under Spring pressure alone to the DHW port. See what the result is.
It won't if he has latched it manuallyEven easier, if he simply turns all the power for his boiler etc. to off, a spring return valve should go to the DHW position.
It won't if he has latched it manually
Hi, Andy yes if i put the heating on the rads heat up
Alec T - They automatic valve is generating heat at both outputs A and B and the same heat, even with what i have just done for Any it generated the same heat on both the A and B outputs and that was with HW only on using the programmer
Harry - flushing might be my only option before cutting it out, it can't do any harm me adding cleaner to the system can it? i will still be flushing it all anyway as there is quite an amount of crap seen already in the expansion tank
