my barton pressure cooker won't build up any steam, it just leaks from the side. what's wrong?

Diagnosis

Your Barton pressure cooker is leaking steam from the side because its primary seal has been compromised. This almost always indicates one of two core issues: 1) The silicone sealing ring (gasket) is either damaged, has lost its elasticity, or is improperly installed, or 2) The lid is not locked into the pot correctly, preventing the ring from making a complete seal. A secondary possibility is a clogged or stuck pressure release (floating) valve, but that typically causes steam to vent from the top, not the side.

How to Fix It

Follow these steps to restore the seal:

1. Turn off the heat, carefully release any residual pressure using the quick-release valve, and open the cooker.
2. Inspect and reseat the sealing ring. Remove the ring from the underside of the lid. Check for cracks, nicks, or a permanent flattened shape. Even if it looks fine, wash it in warm soapy water, dry it thoroughly, and reinstall it, ensuring it is seated evenly in its groove without any twists.
3. Check the lid alignment. Place the lid on the pot. The arrow on the lid handle must align perfectly with the arrow on the pot handle. Rotate the lid until the handles click into place and the arrows line up exactly—this is the locked position.
4. Clean the pressure release valve. Remove the small, movable metal valve (usually in the center of the lid) and its housing. Clear any food debris that could prevent it from rising and sealing properly.

If That Didn't Work

If steam still leaks after the steps above, the sealing ring itself is likely the culprit. Over time, heat and use degrade silicone, causing it to harden and shrink. You need to replace the sealing ring with an authentic Barton 6.0 Quart replacement gasket. Also, inspect the rim of the pot and lid for any small dents or warping that could prevent a tight seal. If you find physical damage to the aluminum body or lid, do not attempt to repair it.

Heads Up

Never use a pressure cooker that cannot seal and build pressure, as it will not cook food safely or correctly. If the pot or lid is dented, discontinue use immediately and contact Barton or an authorized service center, as damaged aluminum can be a safety hazard under pressure.
