What's wrong with a high pressure cooker?
We are doing the Korean high pressure electric rice cooker, you said the sound is not to say that at the time when when cooking meal fast good voice, that is normal, because the pressure cooker to ensure internal pressure is maintained at a certain pressure range, so to adjust the internal pressure in the exhaust place, and because of the internal water vapor so that will sound. I don't know if your question is like this
It depends on where it is, the old sound:The edge of the pan may leak, mostly the sealing ring;Float valve ---- possible hole is not right, the top can not be sealed;Pressure limiting valve ---- used for a long time may be deformed, it may also be aging sealing ring, resulting in leakage;Pressure switch jump sound ---- frequent beats, pressure is not adjusted, to professional maintenance personnel with pressure gauge re tune.
