Concealed Cistern Issues

[Paul-man]

We have a relatively new loo, but a problem with the flush.

Firstly, the side entry float valve gets stuck down, so after a flush the cistern doesn't refill. If I open the access hatch and touch the top of the float, it springs back and starts filling.

This sometimes exposes a second issue, which is that the flush gets stuck OPEN, so the water doesn't refill, it simply pours straight down the pan.

I think it would be awkward to change the whole cistern, though I feel this might be the best way. Is this a common problem? Would changing the side entry float to a different brand/type help?

The cistern and fittings came as part of an online bathroom order, so I'm sceptical about the quality.

Is the flush valve cable operated ?
Is the float binding in any way ,on cistern wall maybe ?
Replacing both valves may be necessary ,but the cistern wouldn't need to be.

The flush is cable operated.
I currently have the lid removed, which helped the problem at first.
Float doesn't seem to be binding, but onlubhabe access from the front, so not easy to see what's going on.

Thanks
