Have you got 230V between L&N in the shower terminal block and if not, 230V between L&E?.

Thanks for replying yes sorry should have put it in yes it reads 239v tested all everything test 239v

Not even a dribble from the shower outlet/hose? even after confirming water pressure at the shower inlet?. Have you confirmed 239V in the shower terminal block with the solenoid energised?
What about the pull cord switch??.

A basic question but you said you have plenty of pressure going into the shower. How do you know? Test?

What’s feeding the shower? Mains? Tank? Have you looked for a check valve on the supply line that could be jammed?

Hi thanks for replying feeding the shower is mains I removed the shower connector loads of water coming out but not filling the shower tank

So, you are saying that there is or should be enough pressure to flow out of the shower (at least)? If you put your finger over the supply pipe can you feel "pressure".

It seems to me that the solenoid valve isnt opening and ditto problem with the last shower.
Did you check for 239V with the solenoid energised.
Maybe worth just running a supply to the shower via a extension lead or whatever, switch the shower to cold, switch off the the power supply to the shower at the consumer unit, MCB/RCBO or whatever, then connect in the temporary power supply to the shower terminals and see if you get (cold) water from the shower?.
