1, maintenance failure of electric pressure cooker 1, and the use of electric pressure cooker often leads to the phenomenon of pot paste. Maintenance method: the electric pressure cooker burned out because the mechanical timer stopped timing or the rotary button got stuck. When we repair the electric pressure cooker, we need to replace the rotating button of the timer so that the friction between the button and the panel is zero. If the temperature of the computer sensor of the electric pressure cooker is too high, replace the sensor of the electric pressure cooker.

2. Maintenance failure of electric pressure cooker 2. The edge of the electric pressure cooker leaks. Maintenance method: If the edge of the electric pressure cooker leaks air, first check whether the sealing ring of the pressure cooker is put away, damaged or foreign, and replace or clean the sealing ring when repairing the electric pressure cooker. The deformation of the inner container of the electric pressure cooker will also lead to air leakage at the edge of the lid of the electric pressure cooker, so the inner container should be replaced.

3. Maintenance failure of electric pressure cooker 3. The pressure limiting safety valve of electric pressure cooker leaks air. Maintenance method: the exhaust pipe of the electric pressure cooker is worn, which leads to air leakage of the vent valve. The exhaust pipe should be replaced when the electric pressure cooker is repaired. The pressure limiting and relief valve on the cover of the high-pressure boiler leaks due to poor exhaust, and the pressure limiting and relief valve should be replaced when the electric pressure cooker is repaired.

4. Maintenance failure of electric pressure cooker 4. The float of the electric pressure cooker can't rise. Maintenance method: the reason why the float of the electric pressure cooker can't rise is that the float is stuck by the push rod connecting plate. When maintaining the electric pressure cooker, send the electric pressure cooker to the maintenance point for maintenance, so as to avoid damaging the push rod plate during maintenance. If the lid of the electric pressure cooker is not covered properly, the float of the electric pressure cooker will not rise, so cover the lid to a safe position before taking it out for maintenance.

5, electric pressure cooker maintenance failure 5, the lid of the electric pressure cooker can not be opened. Maintenance method: If the float of the electric pressure cooker does not drop, the lid of the electric pressure cooker will not open. When repairing the electric pressure cooker, just gently press the float with chopsticks to make it fall and open the lid. Problems such as the angle and burr of the push rod connecting plate of the electric pressure cooker can also cause the lid to not open. During maintenance, it is necessary to replace the connecting plate of the push rod, or twist the push rod upward with a sharp mouth when the push rod is exposed for the longest time, so that the problem that the lid of the electric pressure cooker cannot be opened can be solved.
