Fluidmaster lever dual flush valve problem

[ih]

Hi i have the above in the cistern but after activating flush the lever does not go back and cistern starts
Refilling also water starts going to the toilet if i push the lever up manually this stops the water flow to
The toilet . I will appreciate if somebody can identify the faulty part so i can replace ( if it is the lever
then is it available on its own or do i have to get the complete flush valve. Thanking in advance

It is only £13 for the whole thing at screwfix. Flush valve twists out of base so nothing complicated about swapping the whole thing. If you pick up the replacement you will see how the body of the valve is fixed to the basket on the bottom.

Shut off supply, remove old valve, cistern empties itself, insert new & twist to lock.
