Hot tap valve won't separate from end of tap

[BroadDIY]

I'm attempting to change the hot water valve in our Bristan Colonial monbloc kitchen tap.

I've removed the valve from the tap base but I'm unable to detach the part of the tap you turn despite removing the screw on the end. The valve seems to catch on something as I'm turning it.

Having refitted the old valve as I couldn't separate the end of the tap but we now have no water flow.

Think the valve definitely needs replacing but don't know how to get the tap off the end!

Is this the tap?

Yes.

So which bit can't you get out? Are they quarter turn cartridges or traditional washered taps?

Think its a traditional washered tap. We had low water pressure coming through so Bristan recommended a new valve.

I was expecting to remove the decorative cover on the end of the tap, unscrew the screw and then pull the tap end off the valve.
It won't budge.

So then I managed to remove the tap end and valve (attached to one another) from the base of the tap.

The tap end and valve turn on one another and something between them seems to catch but they won't come apart. Tried using some descaler (as we live in a very hard water area) but that hasn't made any difference.

Can't understand why we have no water flow now, once everything has gone back together either.

Any ideas, would really like to get the new valve in but any hot water flow would be good!!

Thanks for your time and interest.

After lots of fiddling and more descaler, its off!!!

New valve in and working well.

Happy Easter!
