Pigeon electra electric cooker

So i recently got the pigeon electric cooker. I was able to properly make khichdi once in it and after that it is just leaking pressure from the float valve.

We cleaned the thing throughly, there’s no debris or particle stuck near the valve or any such thing but it just does not seem to work. Keeps leaking pressure from the float valve. Tried 3/4 times to cook dal, potatoes and khichdi; all efforts futile and leading to more efforts.

What am i doing wrong?

Also unable to find some videos online. If u have a link to that, that could also help.
