Quick diagnosis: Pressure depends on a sealed system with enough liquid to generate steam. Never force, block or open the cooker while pressurised.
What the Symptoms Tell You
Indicator does not rise, steam escapes from the rim or valve never stabilises.
Why This Usually Happens
The most common causes are connected to temperature, ratio, timing, ingredient condition or technique. Compare the dish with these specific checks:
- Seal is dirty, damaged or incorrectly seated.
- Valve is blocked or positioned incorrectly.
- Liquid is insufficient or pot overfilled.
Professional Rescue Method
- Turn off heat and allow complete natural depressurisation.
- Check indicator, valve and seal only after the manufacturer confirms it is safe to open.
- Correct liquid and load, or arrange service for damaged parts.
Safety and Quality Limit
A pressure cooker can cause severe burns or explosion. Never force the lid, cool contrary to instructions or bypass a safety valve.
Prevent It Next Time
- Inspect gasket and valve before every use.
- Follow minimum liquid and maximum-fill marks.
- Use only approved replacement parts.
Chef’s Verification Test
Restart only when the lid, gasket, valve, liquid and fill level all match the manual.
