Shower booster pump not working (Showerforce Boost)

macgyver

My shower has suddenly stopped working. When I turned it on one morning, the pump did not make any noise and the water did not come out with pressure as it used to.
I bought the house about 3 years back and the shower was newly fitted by the previous owner.
The brand of the shower pump in the bathroom is "Showerforce Boost" and it is connected to a isolating transformer in another room (see pictures)




The lights light up when I turn it on but no noise of the pump and no pressure is generated.

When I turn on the shower the green light is on as was happening before.

The water is still coming out which is useable but under no pressure.
I opened the pump and saw that the round thing rotates freely and no obstruction within the white chamber.
Is it likely that the pump replacement or can it e repaired?

Thanks for looking in.

I was searching online and found a similar looking shower in decent price.

Would this be swappable with the shower I have.
