How to deal with air leakage of electric pressure cooker?

Foreign body blockage and out-of-control control panel will lead to air leakage of electric pressure cooker.

If foreign objects are blocked, this fault requires regular cleaning of ball pads and steel balls.

When the control panel is out of control and the pressure is too high, it is necessary to check whether the relay and related circuit components are damaged and whether the thermistor resistance is within the normal range.

If the float valve leaks, replace the float sealing ring. If the cover leaks, please replace the sealing rubber ring, pot liner and cover. If the float is resisted by the push rod connecting plate when it rises, the push rod connecting plate can be pushed away with a small screwdriver.
