It sounds like you have a system whereby the pump is activated by a switch under the tap. You will need to access the underside of the shower control, where there will be a microswitch. Maybe a wire has just become detached, or you may need to fit a new switch.
Do they have a one-way valve to stop it draining back to the tank, does it start flowing if you leave it open? can you hear the pump running when just open the shower tap? I wonder if it's the switched type and the switch has stopped working.
That’s what I was thinking about, the micro switch but couldn’t remember what it was called.
Would this be located behind the shower mixer tap and if so, how do I remove this? I don’t want to start disturbing any of the shower panels but needs must.
No, I cannot hear the pump priming when the shower tap is open.
Could there be an air pocket in the system? If there is a leaky pipe somewhere you may have an air pocket. Again, if the system has been drained down after your last outing, by refilling it you may have pockets of air.
No, I cannot hear the pump priming when the shower tap is open. Presumably the switch isn't working then. An airlock wouldn't affect the electrical circuit!!
If you have one of the Reich shower mixer tap, like I had you need to remove the red/blue inserts on top of the handle with some thing suitable.Underneath you will find a screw which secures the handle. Once the screw is of you can lift the handle off and underneath you will find the microswitch. The wire had broken on mine and I just soldered them together and finished with a shrink wrap over the top of the repair.
I had the same problem with the tap to the kitchen sink where one of the wires had broken. It was a difficult solder as the break was right where the wire went into the body of the microswitch. The repair last 6 or 9 months before it came apart so I decided to replace the microswitch with a new pre-wired one. I ran the wires back down through the tap and joined them up below the sink. Not sure though that access would necessarily be that easy in a shower.
Ok, here’s the said shower control
Tried bleeding but still the same and all the other taps work fine.
If I open the bathroom sink tap slightly the shower works fine.

If it is too difficult to access or remove then try to locate the wires going to it and install a separate switch that shorts the wires to operate it. You could of course do this anywhere such as connecting a parallel switch across the wires to the sink or indeed at the pump itself and locating it adjacent to the shower. [PS of course the switch is only in the positive wiring to the pump NOT across the positive and negative].
It has to be the switch. Think about it. Open the shower tap, nothing happens so the switch clearly isn’t telling the pump to pump.
Open the basin tap and it’s switch DOES work and “tells” the pump to pump.
The pump doesn’t know which switch is “telling” it to work, and it doesn’t care it just needs A switch to tell it. In this case the one on the basin is doing it.
It’s the shower mixer switch that duff (or the wiring to it)

Why do manufacturers fit such complex Systems that work off an electrical switch on each tap? A single pressure switch somewhere in the system is much simpler and has much less to go wrong.
I agree with the others - definitely the micro-switch or the wiring to it. I would hope it should be relatively easy to remove the tap head to access the micro-switch and see whether the wiring has come apart.
Brilliant that Ray, thank you taking the time to find it 👍
Thank you all for your replies, much appreciated honesty 👌
Funny thing happened
I had the shower tap open, no water coming out. I had it open because it was at a better angle to see the red & blue grommet which I started to remove using a small blade. There must be a loose wire on the micro switch or something because all of a sudden I got
SOAKED 😂😂😂
Now I know you will all say that I should have turned the power off but I hoped I might disturb the wires and it could burst into action which is exactly what happened 😀😀😀
It’s working now so I will leave it alone for now but know it will need a proper fix. I don’t think it will take a big hammer fix 👊
I’ll keep you updated 😉
