1. It may be that the rubber band on the lid is aging, which leads to the pressure cooker not being completely sealed, so there is no pressure. In this case, users can purchase rubber bands with the same specifications for replacement.

2. It may be that the lid is not covered properly and the pressure is leaking out. In this case, you can reopen the cover and then close it.

3. The pressure may be too low due to the blockage or failure of the safety valve. If the safety valve is blocked, clean it up. If the safety valve is faulty, it is recommended to find a professional to replace it.

Solution:

1. fault condition: when the electric pressure cooker is powered on, the display screen does not light up, the operation button does not respond, and the cooker does not generate heat.

Solution: First, check the use of fuses. If it is in an open circuit state, a new fuse needs to be replaced. If the fuse is normal, continue to check the use of the bottom thermostat. If the thermostat fails, it needs to be replaced with a new one.

2. Fault: After the electric pressure cooker is started, it will automatically shut down after a period of normal operation.

Solution: This fault may be that the thermostat is broken, and the thermostat of the same model needs to be replaced.

After induction, the thermostat will automatically close and can be put into use again after the temperature drops.

3. Fault condition: the electric pressure cooker leaks air.
