Toilet Cistern Siphon not working

Hi,
Our toilet has been flushing less & less reliably. As it's see through
plastic, I can see that when the plunger which should lift the water
up into the u-bend of the cistern to start the siphon, is failing to
do so, almost gets there.
But I can't see anything wrong.
Is there some kind of seal around the plunger which may have
disintegrated?
There's a flap valve at the bottom of the siphon that has prolly failed.
Ypu do not need to replace the cistern, but you will need to replace the
flap, and probably better, the whole assembly, they're not expensive.
You will need to remove the cistern from the bog, and there is a rubber
sealing ring that is probably a good idea to replace at the same time.
Prolly wingnuts underneath will release the cistern which will just lift
off after disconnecting the pipes. These nuts can be a bugger to undo on
account of rusting corrupting, on reassembly grease up nicely.
