You could just reseat the existing ring after cleaning but if I have a new one on hand, I’ll try that first and give the old one a second chance later.
Also, be sure to remove and clean the float valve (the little pin that pops up when it comes up to pressure). The one time I had a problem it was some invisible bit of schmutz in that part. I took the gasket out and cleaned it, took the float valve out, q-tipped the hole and the pin (nothing visible came out or off), and reassembled. Problem solved.
