Toilet not flushing

[ssray]

Hi, We have a tywford lowlevel cistern with a tywford o2 flush?
Its only flushing if the handle is depressed a number of times-like you are building up pressure- to repair do i have to remove the cistern or is the internals removable without?

Any ideas what it could be?

Maybe the membrane in the syphon has split so it loses it's lifting power ?
