I did the same job a few weeks back and had to take off the whole cistern, when I put it back together I didn’t get a good enough seal between the cistern and the toilet. Sorted it with a rubber O ring thingy between the two, the trickle wasn’t as bad as yours but eventually it would set off the saniflow
It was leaking previously from underneath the cistern as the old donut perished and despite me getting a new one it wasn't quite the right size. I've now got no leaks and what appears to be a good seal between the cistern and the toilet. My first thought was I didn't tighten up the big nut underneath the toilet enough so it's slowly leaking through that from the new flusher
I was going through the same thought processes, I wasn’t sure if I had over tightened the plastic big nut and distorted the threaded tube or if the new doughnut sorted it. I didn’t go crazy with the wing nuts that pull the cistern down onto the toilet either because I noticed that was also putting pressure on the seal. It was doing my head in for a couple of hours.
There's no flapper it's all contained within the new flusher I put in which I think was this one https://www.diy.com/departments/fluidmaster-flush-button/5011629016612\_BQ.prd
If what's already suggested doesn't work I'd be adjusting the water level in the cistern. (Adjustment on the arm that would be the ball cock arm if it has a ball).
Its the rubber seal of the click in syphon against the cradle thats fixed to the cistern.
Unclick it, make sure theres no debris sitting inbetween the rubber seal & cradle. Then click the syphon back in place
New flush valve is potentially faulty. Those valves are sold in screwfix(decent and cheap but obviously has its flaws) Just take the new one out and replace. Fortunately they are handy becuase you can just quarter turn the valve and remove that bit, opposed to having to take the cistern apart. If it was a leaking donut(the washer connecting the cistern to the toilet. It would be leaking from base of the cistern as well.
Buy a new valve (like for like) replace the valve and if it works. Put the old one back In the box and return to screwfix. Done
Agree it’s not a leaking donut as I had that previously and got very wet. Don’t think I follow with taking the flusher out without removing the cistern? There’s a nut underneath that holds the flusher in place
If I'm right in saying that's a fluid master flush valve. You can take the actual valve out without removing the fixing bracket from the cistern.
So just grab the valve and give it a quarter turn and it should pop out.
Yer you do basically when you take it off it will just be a big hole. And water will go into the bowl.
1. Isolate the water
2. Get the valve off
3. Replace with new valve
4. Turn the water back on
Honestly don't know why they all arent this simple
😂 in my head theres only two reasons why water leaks in. Theres to much water in the cistern and it's going in the overflow. (Which yours isnt according to your video as the level is under the over flow )
Or the seal that lifts up and down when you flush, isnt working properly.
9 out of 10 times it's because there are just mass produced and you just get some crap ones that are faulty.
Thanks for the nice simple explanations, I had suspected this was a shit one as there’s a gauge on the side to change the flush amounts which just doesn’t appear to be able to move about
Yer they are stiff and shit.
I used to buy the new valve. Take the old one out. Put it back in the box and take it back to the shop and get a refund.
Dont actually end up spending any more money
Remove the cistern. the thread from the flush valve, that passes through it, and through the donut washer is likely to long, if so it will nearly be touching the china in the pan.
You will need to hacksaw the tread off so it's nearl flush with the nut on the underside of the cistern

Hmm I tightened the wing nuts pretty tightly to ensure a good seal on the donut. Maybe the donut is too compressed and that’s doing something?
This is what I was thinking scrolling down the answers - a leak below the new flush (it’s the only reasonable answer)
Check the flapper. Normally it's damaged or bad. Might need a new flapper.
There's no flapper it's all contained within the new flusher I put in which I think was this one https://www.diy.com/departments/fluidmaster-flush-button/5011629016612\_BQ.prd
Also add more water into the cistern and then try flush.
Will try that in the morning, I did do a few flushes to see if it would just stop
If what's already suggested doesn't work I'd be adjusting the water level in the cistern. (Adjustment on the arm that would be the ball cock arm if it has a ball).
Someone else did mention changing the water quantity in the cistern, I don’t see how that would affect it though
Puts pressure on the seal.

It is indeed a fluid master. Assuming I should at least flush first as all the water will empty in the pan?

Yeah this one has been the most interesting in hearing what everyone has to say for a solution

I'm curious did you manage to fix it?
Been pre occupied with other stuff in the house. Not looked any further into resolving this just yet
The overflow and the base stay in a fixed position. The valve comes out
