Repair a fake Supor electric pressure cooker E4 failure, after the detection system pressure switch bad contact. Replace repair, but do not know Zeyang adjustment, worry that can not repair the original state will explode! Dare to ask heroes who have what coup adjustment!
Feeling not take ha ha ha, do not luck so good, do not tune
Debugging method: Remove the electric pressure cooker plastic bottom cover, the electric pressure cooker pressure detection switch put on, with the screwdriver to adjust, when the switch is completely closed and then turn counterclockwise N ring, the pot filled with water (about 500ML can ), Installed on the pot and screw the lid, the exhaust of the small iron also installed. Heating the water to boil for a while, see the steam from the vent hole, and then a while, a large number of steam out, and issued a "hissing" sound, then the power cord pulled out, carefully from the pot The bottom of the pressure detection switch clockwise slowly adjust, when you hear the switch off the sound immediately stop, and then power to continue to heat the pot of boiling water, I saw the exhaust hole is only a slight water vapor, Time to turn on the insulation state.
Pressure switch to the valve when the gas out of the air will be broken, let go of a little gas can be closed, the valve gas on the broken. : Handshake I was so tuned
E4 pressure switch failure 1. Pressure switch contact moisture oxidation 2. Pressure below 0.04MP on the first case of the oxidation point can be dealt with clean; the second case you have to adjust the pressure switch, the method is as follows: Electric pressure cooker pressure There are two ways to adjust the switch, 1. Hand pressure gauge: add appropriate amount of water to the pot, cover the lid to boil, remove the pressure relief valve on the pressure gauge, etc. Table read rose to 0.068MP when the adjustment pressure switch So that it is just broken; with glue fixed adjustment screw. 2. do not have a pressure gauge on hand, do not remove the unloading pressure valve, the first pressure to the maximum, and other relief valve just began to leak, immediately adjust the pressure switch to jump, and then clockwise and then spin a Little bit on the line. Remember to use glue to adjust the screws.
