Mira Mixer Shower No Hot Water

[TDA]

Please can someone help! I think ( am not sure) I have a mira (defo mira) it is either power shower, or mixer shower, its stainless steele plumbed into wall. Gas boiler provides the hot water.

This morning I used it, it was fine, although when I went to switch it off it just kept dribbling, but this stopped eventually. Then my son tried to use it and it wouldn't come on at all. I managed to twist the dial to get it to come on, however it is lovely and powerful, but there is no hot water. The shower just has the dial to turn on water and the one for the temperature.

The gas boiler provides hot water to taps, c heating, etc and all of these are working. It is just the shower that has no hot water as i've checked.

Does anyone have any advice as to what this could be, as I am unsure whether I need to get out our usual heating services firm for the boiler, or to find a plumber to look at the shower itself.

Thank you for your advice in advance, as I just have no clue what the issue could be, but am assuming it is shower related, as the boiler is working for everything else. It is a Worcester 28CDI boiler.

Hi, please could I ask what a sear clip is and is this something in the shower, or the boiler?

It's a clip on the spindle
Take the cover off and it should be a round brass coloured round clip
That's only a maybe it has come loose

well i've restored the hot water by taking the shower apart, the boiler kicks in. however the first time I put it back together I couldn't regulate the temperature it was too hot. So, I took it apart again fiddled with a black valve in it (after taking out a purple cog that was screwed in, and then put it back together and I couldn't switch the shower water off. Took it apart again, still couldn't regulate the temperature and then when I tried to turn it off the water wouldn't go off. Took apart again, and this time finally got water turned off and now can't switch the darn thing on at all!

Am pleased to have restored the hot water, but what have I done wrong as in any ideas why I can no longer regulate the temperature firstly and now why won't it switch on at all?

that is so bizarre, as I thought i've have a quick look on ebay, and that is what I am now looking at right at this second, as i've worked out from looking at many pictures it's a Mira Excel shower manufactured between 1996-2003, and have found a brand new one. If I turn the water to the house off, do you think I could easily fit it myself?
