I had the shme experience and may have found a solution. I also bought another gasket, thinking the old one is no good. But, even the new one had same issue. The yellow pin did not pop. So, I pulled back the valve to expose 1 Dot and turned the gas full on, expecting steam to escape from the exposed hole, but that did not happen. Instead all steam leakage stopped and the yellow pin popped up. This was the response needed. Now it held pressure and cooked basmati rice to perfection in 3 min. Post popped pin. Try that and see if yours works too. Good luck.
