What happens when an electric pressure cooker leaks when cooking rice?

The solutions to the exhaust valve that keeps leaking when the electric pressure cooker is cooking rice are:

1. Check the valve gear.

When using an electric pressure cooker to press food, after the lid is tightened, the exhaust valve gear should be set on the sealing gear. If the gear is set on the exhaust gear, there will be a phenomenon that the pot will be exhausted all the time after it is boiled.

2. Check whether the pressure cooker is tightly covered.

If the pressure cooker is not covered tightly, there will also be the phenomenon of air leakage in the electric pressure cooker, which is not only a first-time user, even if it is a frequent user, but also because of a period of sloppiness, resulting in the pressure cooker not covered tightly.

3. Check whether there are foreign objects in the sealing ring of the pressure cooker.

If there is a foreign object on the sealing ring of the pressure cooker, the pressure cooker is not well sealed, and there will also be air leakage. Clean the seals of foreign matter.

4. Check whether the sealing ring of the pressure cooker is deformed.

If the electric pressure cooker is used for a long time, the sealing ring is worn, and the sealing caused by deformation is not good, which will also cause air leakage.

5. Check whether the pot bile and lid are deformed.

If the pot bladder and lid are deformed after bumping, resulting in poor sealing after the lid, it will also lead to air leakage.

6. The float valve of the voltage boiler is leaking.

The float valve of the voltage pot is leaking, and the sealing ring needs to be replaced, if you can't see it, or can't replace it, it is recommended to go to the after-sales service for repair.

7. Leakage of pressure limiting exhaust valve.

The leakage of the pressure limiting exhaust valve is due to the failure of the exhaust pipe, thimble, switch, etc., resulting in air leakage, which needs to be tested and repaired by professional maintenance personnel.

Because the pot is full of steam, the exhaust valve must of course be exhausted to reduce the pressure.

If you can't vent, your pressure cooker will be a bomb.

Therefore, the most important thing about the pressure cooker is the role of the pressure reducing valve and the safety valve.

The safety valve is when the exhaust valve fails.

The safety valve melts automatically.

A pressure cooker can't be a bomb.

1. The exhaust float cannot rise.

In this case, the valve of the float is leaking, the lid of the pot is leaking, or the float is blocked by the connecting rod plate when it is rising, so that it cannot rise normally, and it will always be in a state of air leakage. What you can do is to use a tool to fluctuate the float to see if it can rise up normally, otherwise you can only replace the float, or replace the sealing ring of the float, if the lid leaks, you can replace a new sealing ring, pot bladder, or even replace a new lid to test the problem.

2. The float can rise, but it leaks.

In this case, it is likely that the float is a problem, it may be that something is stuck with rice grains or something, and it will be cleaned out, but if the float is damaged, you need to replace it with a new float.

3. The case of air leakage of the pot lid is more common.

The main reasons are, check whether the rubber ring is placed correctly, and whether the rubber ring is put into the card slot of the lid; There are hardened rice grains on the sealing rubber ring; The sealing rubber ring is damaged and aged, and loses its elasticity; Whether the lid of the pot is well covered, and the lid is covered according to the specified and coupling degree; The lid of the pot is deformed, resulting in the inability to seal; The main body of the inner pot is deformed. In view of the above problems, we can check and check them one by one, and basically we can solve them by ourselves.

4. Air leakage from the pressure limiting release valve.

In this case, most of the reasons are that the exhaust pipe is damaged and the pressure limiting air release valve is damaged, so the only way to do this is to replace the exhaust pipe or replace the pressure limiting air release valve.

In this case, it may be a problem with the exhaust valve of the electric pressure cooker itself, which is caused by whether the relevant parts of the exhaust valve need to be replaced.

When the pressure in the pressure cooker reaches a certain level, it will be relieved through the pressure relief valve above. Be sure to vent it. If you don't exhaust and the pressure relief port is blocked, it will be **.

1. The aging of the sealing rubber ring causes air leakage due to incomplete sealing, and the sealing rubber ring needs to be replaced.

2. If the middle layer of the pressure cooker is lowered due to long-term use, you can use a gasket to raise the middle layer.

3. The heating plate of the pressure cooker is lowered and the heating plate is raised.

4. The lid is deformed and needs to be replaced.

5. If the exhaust hole is blocked and causes air leakage, dredge the exhaust hole.

I've repaired a few of these pots, but I can only say it's experience.

The so-called pressure switch is a device whose temperature limiting threshold is lower than the safety valve. When the temperature reaches the threshold, it will disconnect the power supply to the heating plate, so the temperature in the pot cannot reach the temperature of the safety valve. Even if the electronic switch is completely broken, the safety valve will still work, and there is no big problem in safety, but you can hear the sound of ordinary pressure cooker again.

Open the bottom shell to check this switch, then follow the arrow to adjust the threshold temperature until the aerating valve is just not venting.

If you want to talk about the principle, it can only be said that it is a problem with domestic components, it seems that the contact of the temperature switch wears the heating plate head (I saw a pit in the repair). It can get better after the adjustment, but it will be sick in a few days.

Either find a repair shop to fix it, or buy another one.

1. Check the valve gear first, use the electric pressure cooker to cover the lid tightly, and set the exhaust valve gear on the sealing gear.

2. Check whether the electric pressure cooker is tightly covered, if the electric pressure cooker is not tightly covered, there will be air leakage in the electric pressure cooker.

3. Check whether there is any foreign matter in the sealing ring of the electric pressure cooker, if there is a foreign body, it may cause the electric pressure cooker to be poorly sealed, and there will also be air leakage.

4. Check whether the sealing ring is deformed, if the sealing ring is worn or deformed due to long-term use, you can try to replace the sealing ring.

5. If the pot and lid are deformed after being bumped, resulting in poor sealing after the lid, this will also cause air leakage.

6. If the pressure-limiting exhaust valve leaks, it needs professional maintenance personnel to carry out inspection and maintenance.
