Ensure Proper Lid Placement
Align the lid correctly with the sealing ring in place. The lid should lock securely with the arrow aligned and the handle turned to the sealing position. If it’s not locked properly, the cooker won’t seal.
Clean the Lid and Gasket Area
- Wash the lid, gasket, and sealing ring with warm soapy water.
- Check for any food debris or residue that could prevent sealing.
- Dry thoroughly before reassembling.
Test the Seal
After reassembling, add a small amount of water, close the lid, and set the cooker to pressure mode. Listen for the hissing sound. If it still doesn’t seal, recheck the gasket placement or replace it if necessary.
Additional Troubleshooting Tips
- Ensure the float valve moves freely and isn’t stuck.
- Check if the lid’s locking mechanism clicks into place.
- Inspect the anti-spin device for proper function.
