1, the sealing ring is aged or damaged;

2. The inner pot of the electric pressure cooker is deformed.

Therefore, the maintenance method is:

1. Replace the sealing ring;

2. Correct the deformation of the inner pot or replace the inner pot.

Electric pressure cooker is an upgraded product of traditional pressure cooker and rice cooker. It combines the advantages of pressure cooker and rice cooker, and adopts new technologies and structures such as elastic pressure control, dynamic sealing, external rotating cover, electric switch with adjustable displacement, fully sealed cooking, continuous pressure adjustment, etc., which completely solves the safety problem of pressure cooker and relieves the potential safety hazard that ordinary pressure cookers have plagued consumers for many years.

Extended data

Pay attention to the use of electric pressure cooker

1, when using, first carefully check whether the exhaust hole is clear and whether the hole under the valve seat of the safety valve is blocked by residual rice grains or other food residues. If it is blocked by food during use, the pot should be removed from the fire source. The aging apron is easy to make the pressure cooker leak and needs to be updated in time.

2. The handle of the pot cover must completely coincide with the handle of the pot, so that food can be cooked with electricity, otherwise it will cause an accident of the pot flying cover.

3. When in use, in order to increase the pressure in the pot, someone forcibly increases the weight on the pressure valve and forcibly shortens the production time. I don't know that the pressure in the pot has strict technical parameters. Ignoring this scientific design is tantamount to joking with your own life and will lead to serious consequences. Don't take the risk! In addition, when in use, if the fusible metal piece (plug) on the pot falls off, it must not be blocked by other metal objects, and a new piece of the same kind should be replaced.
