Temperature tap on shower wont turn

[Paul-man]

We have a gravity fed system, with a 1.5bar pump in the loft feeding a thermostatic mixer shower Until today everything has been working fine.

My wife went to have a shower this morning and found that the temperature dial on the shower wouldn't turn fully. (It usually turns to a point, where you can then press a safety button to get it to go hotter) It wont turn as far as this point.

Where should I start in fixing the problem?

Any ideas anyone? By turning really hard with a dry hand I've managed to turn it almost as far as it usually would. What could cause this to suddenly go stiff?

remove the cartridge and descale it.
may need new seals depending on what shower it is.

make/model ?

Viagra? Sorry, could not resist.

Thanks.

Not sure of the make or model. On the screw cover is a word written in a fancy script- looks like Bianca. However, when I search for Bianca Showers on Google, I get some strange results.

Maybe Bianra? I can take a photo but not sure if this would help or not.

The controls sit on a chrome plate on the wall which is sealed with sealant. Do you think this would need removal?
