How can I fix my Gainsborough 8.5 SDL shower?

Funny you should ask this question, same thing happened to mine today. I am currently looking for spares on the web.
I have found the problem with mine. The thermal cut out has stopped working and is 'cutout' all the time!
Firstly check the power is on and the water pressure OK. If yes to both, switch the power switch off, take the front cover off. Check the two water heating elements with a meter for continuity, the water pressure switches and the thermal cut out. If in doubt seek professional help.
Hope that helps

John - mines stopped working too!
