TEFAL Cook4me Manual page 49

If one of the overpressure safety features is triggered:
Turn off your appliance.
Let your pressure cooker completely cool down.
Open it.
Check and clean the safety valve, decompression ball and gasket. See chapter on Cleaning and Maintenance.
If your product leaks or is no longer operational after having performed these checks and cleaning, return it to a Tefal
authorised Service Centre.
Regulating your appliance:
The pressure can be regulated by switching the heating element on or off.
To minimise the effects of thermal inertia and improve regulation accuracy, the decompression ball can be
automatically triggered to briefly release steam from time to time.
