Loss of water pressure in Bristan Electric Shower?

[Tomzmuffin]

Hi A few weeks ago whilst in the shower a fuse went and the shower turned off. I flicked the fuse back on and the shower restarted but the pressure had gone. To have the pressure we previously had it had to cold, the only way we can have a hot shower it to turn the shower temp up high and have it on the pressure setting on the shower head. I have checked the boiler and the pressure gauge on there is fine its between 2-3 so why do we not have any pressure in the shower?

Please help this is annoying me now.

if its an electric shower it has nothing to do with the boiler, they only have a mains cold feed.
