Replacing thermostatic valve on Ctv A3102aa

Just wondering how difficult it is for a layperson to install these thermostatic cartridges. I've opened my shower up but I can't see how to remove the defective cartridge without taking off the whole shower face plate which would seems like a bigger job.

Replacing the thermostatic cartridge is fairly easy however you will have to turn the water off and remove all the cover plates to get in to the head nut on the cartridge.

My advice is to take many photos as you disassemble the covers note the position of the knobs and carriers perhaps marking the positions with a felt tip pen these can then be referred to when reassembling.

Thank you very much for your reply. Are any special tools required to do this? The part I struggled with was removing the face plates which are numbered 2, 3, and 9 in the parts diagram. The main larger face plate is siliconed to the tiles so wondering does this have to be removed, and the part numbered 3 seems impossible to remove without taking this larger plate off. Anyway, in the end I was worried about breaking something, so have phoned a local plumber, seems like a straightforward enough repair so it's a pity I couldn't do it myself, but like I said, worried about breaking another part.
Thanks for your help, and for the prompt delivery of the part. Fingers crossed for a hot shower at some point before Christmas day.

The above is your shower.

I am often asked “Is this a DIY job” to be honest I can’t answer that, because without knowing someone, it isn’t possible to assess their skills?

I should say that most jobs on showers although relatively easy (from my point of view) can be fiddly and an extra pair of hands, long thin fingers and the strength in your hands of an all in wrestler are a help!

The secret is, observing very carefully when things are taken to bits, their order and orientation, taking notes and/or photos as you go can also be a help.

When you are working with electricity and water so make sure it is switched off and turned off before you start.

If you think you can do the job but aren’t just that confident, it may help to buy the part and compare it to the faulty part, you will then be able to see where the screws, wires, nuts, or washers etc. go, if then you think it is to complicated, at least you will have the part when the plumber or electrician arrives.

We will always be here to offer help and advice if you run into a problem, however it is not the same as being on site where we can get the overall picture, if you are still not sure, now is the time to call in a professional.
