Sealing issues in an Instant Pot can stem from a variety of factors, many of which are straightforward to diagnose and fix. One of the most frequent culprits is a damaged or worn-out gasket. Over time, the gasket can degrade due to repeated use, exposure to high heat, or improper cleaning. Cracks, tears, or warping in the gasket can prevent it from forming an airtight seal, leading to pressure leaks. Another common cause is improper lid placement. If the lid isn't securely locked onto the base, the Instant Pot won't seal correctly, resulting in failed pressure buildup.

Blockages in the venting system are also a significant contributor to sealing problems. Food particles, debris, or mineral deposits can accumulate in the steam release valve or anti-block shield, obstructing the flow of steam and disrupting the pressure regulation process. Additionally, using incompatible accessories, such as oversized steam racks or improperly sized sealing rings, can interfere with the Instant Pot's ability to maintain a proper seal. By addressing these potential issues, you can restore your Instant Pot's sealing capabilities and enjoy consistent cooking results.

In some cases, sealing problems may arise from user error, such as overfilling the pot or neglecting routine maintenance tasks.
