Check whether there is electricity in the home power plug. You can try plugging it into the mobile phone charger.
Check whether the two ends of the power plug are plugged in properly, and remember that it is both ends, not just the power part.
If you check that all the power plugs are electrified, try it according to the normal operation and wait for a while to see if the pot is hot. If so, the indicator light of the electric pressure cooker at home is broken. ?

Pressure cooker principle
The principle of pressure cooker is to raise the boiling point of water with higher pressure.
A detachable heavy iron weight in the middle of the pot cover is used for constant pressure.
When the pressure in the pot just counteracts its gravity, it will be jacked up.
After jacking, the pressure in the pot is reduced, and the water inside will boil violently.
When the pressure is less than the gravity of this thing, it will fall again.
There is also a safety valve near the cover. The old one contains a thin metal sheet called fusible sheet.
If the hole in the middle is blocked, it will melt and release the pressure. The new model is already a constant pressure valve with spring.
