Shower water too warm.

Hello.

The shower is almost identical to the one in this link, except it has a sliding button instead of a push button on one of the knobs.

The hot water knob had become almost impossible to turn to reduce the temperature after the point where the button clicked, so I decided to remove it to take a look and I think it has now become easier to turn but now the water has become too warm for a shower.

I have searched and seen a few suggestions on this site for similar posts, but before I try any of them, I think the suggestions could be further narrowed down due to the fact that the problem only suddenly happened when I removed the knob and re-fitted it. I have seen suggestions about scale, but why would that suddenly be a problem just by removing/re-fitting the knob? I've also seen a suggestion that the knob may not be fitted the right way, but whichever way it is fitted, it turns half a turn anyway, so can fitting it the wrong way really have any effect of the temperature? Wouldn't it just be a case of the button/handle being in the wrong positions visually? I have tried re-fitting the knob in different positions but this hasn't made any difference.

Just an extra question for any manufacturers that may be reading this, when a person is taking a shower, wet and soapy hands are to be expected. Is there a reason you design knobs with tiny, fiddly 'grips' and buttons?

Good to be back! It's now almost impossible to avoid sites with the same cookies problem!

Thank you.

That is how they are meant to be adjusted, made hotter/colder.

Take the knob off, turn the spindle a bit (to a cooler setting), then refit the knob. You might be lucky.
