Toilet flush pressure question

[loted932]

Hello, I have a question on flush pressure.
When I press the bigger button, there's hardly a flush. I understand that's normal but it's a very minimal flush. And then the smaller button is quite hard to press and I think doesn't do a full flush either. So when I flush I press both and it works ok. But I'd like to fix this because I have guests coming.
Can anyone advise on how to sort it out/replace/adjust?

I think the little button is already touching the release/ it's flush against it, excuse the pun.

If you press the big white disc ontop with the screw in once eg imagine it’s the button does it flush proper or small amount ?

Eg does the cistern empty

Could you post a picture of the underside of the cistern lid so we can have a look at the other side of the push button, thanks.

It’s the ideal standard one with a massive white plastic disc under the button.

Thanks for your reply. I took a video but cannot share a link here, it's says it's spam. Most of the water goes down with a single push, all of it with a hold.

I think the issue is that it's stiff to push the smaller button

still same issue, I haven't done anything. Should I swap it out for a better flush?
