Looks like there's no power, button should be lit.
Which button? Usually just the two led lights- blue and red, both look lot on photo above, don't they?
This is photo of isolating electric switch in cupboard behind shower- lights on
Where's the fuse?
Check the pull cord or outside switch and fuse.


The brown thing 2 up from your death stick (volt pen/stick, which FYI doesn’t prove anything other than possibly some voltage).

Yes ,you can buy a new solenoid. But first you need to establish the voltage at the showers main terminal block between live and neutral is 230/240 volts.
The solenoids resistance can be checked with a multimeter to determine if that's at fault .

Have I checked solenoid with correct setting on multimeter? I did it with electricity off.
The resistance check the numbers went up then down to 0 quickly but i pressed hold quickly and got 55.3.
And correct setting for voltage and placing of probes for that?

Normal coil resistance should be ~ 3.0K to 3.5K.okms, 3000/3500 ohms), Set the resistance scale to 20K and see do youget a steany resistance reading of 3.0 to 3.5 ish, it will not read the correct resistance even on a "good" coil if set to the 200K, I have a old Triton coil in my box and it reads 3.75 on the 20K scale but on the 200K scale jumps around a bit and then reads _1 which is meaningless really.
