Power Shower - temperature dial stuck

[amatos]

Hi,

I've got a power shower in one of my bathrooms where the temperature dial is stuck and won't move. I just moved to this property and I don't know if the dial was working before (and I can't check with the previous owners either).

It's a Wickes aquatronic thermostatic power shower. I guess it's rebranded by Wickes, but I don't know what the original brand would be.

The dial has a button that if pushed supposedly would allow you to rotate it, but that doesn't work. There's also a small screw in the middle of the dial - I've tried to unscrew it but even with it removed I cannot remove the dial to check further.

Just wondering if it was installed to be like this? We do get hot water and the flow dial does work. Seems a bit odd that you wouldn't be able to control the temperature but I haven't used power showers before.

Any ideas on how to fix it?

Thanks.

I think Triton made them, if so time to replace Is it an aquatronic 1/2/3?

It's a Triton alright, it's mentioned in the guarantee. I don't have anything else unfortunately. There's no model number neither in the unit nor in the manual. The unit seems to be from 2009, as there is a copyright notice at the bottom of the manual. I could post a picture if it's helpful.

You take that screw out, and pull off the dial. Screws top and bottom to then take the cover off. Sounds like that dial and temp limit button has been replaced incorrectly if it won't work.
Mind and isolate the shower from the mains 1st , water and leccy
