VI. Trouble shooting
If any abnormal phenomenon been found, you shall turn off the fire
immediately and take the cooker to a level place and shower the cooker
with water slowly to reduce the temperature and the pressure. Find the
reason and solve the problem with the table below.

Heating
In order to raise the temperature quickly, heat with strong fire till the
pressure-limiting valve begins to work. Pay attention not to using stronger
fire than which is enough. It is normal that a little steam seeps from the
safely open-preventing valve after heating for a while. There should be no
steam seeps after the open-preventing valve rises and the cooker works
normally. When the pressure-limiting valve raised and steam comes out
continuously, should use gentle fire and start to count heating time.
Caution: Heating time is from the pressure-limiting valve starting to
work to turning off the fire.
◆ Stand by and watching while cooking.
◆ Do not touch the cooker’s metal surface with hands or body. Cook
carefully and use the handles to avoid a burn.
When heating time is up, turn off the
fire and leave it for a while waiting for
the pressure reduced. Take off the lid
when the safely open-preventing valve
fell down. The opening procedure is
contrary to the closing. (Fig.7)
Caution: Shake the cooker gently before opening to eliminate the foam
inside the cooker when cooking sticky food.
5. Cooling down quickly
Sometimes it needs cooling down quickly when cooking over time, or
preventing cook over time, or the cooker needs to be opened during
cooking. Put the cooker on a level place and shower the cooker with cold
water slowly till the safely open-preventing valve falls down.(Fig.8)
Caution: Avoid water flowing into the cooker through the safely
open-preventing valve.
Problem
Steam escapes from safely
open-preventing valve,safely
open-preventing doesn’t rise
up.
Pressure inside the cooker
doesn’t rise
Steam comes out from the unde
side of the lid.
Lid cannot fix properly.
When cooking, the sealing
ring is suddenly forced out from
the safety valve window and
steam drain out.
1. The safety function of the sealing
ring is working. Maybe other device
has lost its function.
2. The sealing ring is aged and has
lost its function.
1. Take away the cooker. After it is cool, clean
and check all the safety devices. Change
the ones which have lost its functions.
2. Change the sealing ring.
The shape of the lid changed.
Change the lid.
Steam still leaks after the safely
open-preventing valve raised up. 1. Safely pen-preventing valve is
not clean.
2.”O”ring is aged or broken.
1. Clean the safely open -preventing valve.
2. Change the “O” ring.
1. The energy from the range
is not enough.
2. Water inside the cooker is
not enough.
3. Safely open -preventing valve is
dirty.
4. Sealing ring is dirty.
5. Cooker lid doesn’t fix
properly with the cooker.
1. Sealing ring is dirty.
2. Sealing ring is too old.
1. Clean the sealing ring,
cooker mouth and lid.
2. Change the sealing ring.
When the pressure inside
the cooker is low, safely
open-preventing valve
doesn’t return to its normal
position.
1. The pressure inside the cooker is
over that to open the cooker lid.
2. Safely open-preventing valve is
not clean.
1. Lower the pressure inside the
cooker to have the locking pin down.
2. Press down the locking pin, open
the lid, then clean the locking pin.
1. Raise the energy of the range.
2. Add more water.
3. Clean the safely open- preventing
valve.
4. Clean the sealing ring, the cooker
mouth and the cooker lid.
5. Fix the lid properly.
