🔗I don't have a warranty card. What to do?How to get a warranty cardQuestion: My black valve is loose, is it a marriage?Answer: No, that's okay.
Question: I am getting steam from under the lid, what should I do?Answer: Check the fit of the silicone ring, make sure it is evenly tucked into the retaining ring in the cover. If the ring is in its place, but steam continues to come out, then remove it and boil for about 10 minutes, as a rule, after that the ring takes on the desired size and the steam output stops. The vaping can also stop after a few times of cooking.
If boiling does not help, then return the pressure cooker to the store.
Question: I am getting steam out of the closed black valve, is it a marriage?Answer: If the pressure cooker builds up pressure while doing this, then a little steam / sizzle is acceptable and usually not a hassle when cooking. A possible cause of the phenomenon is a loose nut on the inside of the cover or a slipped silicone gasket in the valve. Remedy: From the inside of the bonnet, remove the protective metal valve cap. Unscrew the nut, disassemble the valve, correct the gasket, reassemble the parts in reverse order and tighten the nut well. The very procedure for assembling and disassembling is simple and the main difficulty is remembering the sequence of assembling the parts.
Question: I don't have a countdown timer.Answer: The countdown starts after the pressure cooker reaches the parameters set by the manufacturer, for example, on the "ROAST" program, the timer starts counting down after the temperature reaches 170 degrees. Wait for the countdown to start and then add food to the bowl. On programs with pressure, the countdown starts after the pressure is increased.
Question: I bought a pressure cooker, but my lid is loose (backlash), is it a marriage? Answer: This is not a defect, after the pressure is set, the cover will be securely locked.
Question: Can the lid be washed under the tap?Answer: Yes, this is permissible, you will not damage anything with water. After washing, rotate the lid around its axis to allow water to drain from the process holes.
Question: How to clean the black valve.Answer: There are two options for washing, depending on the degree of pollution - with partial or complete disassembly of the valve. 1. Using light pressure, pull up the black valve and flush it under the running water. 2. From the inside of the cover, remove the protective cap and disassemble the valve completely. Rinse and collect.
Q: Where to buy a replacement silicone ring and which non-stick bowls are suitable?Answer: Native rings are already on sale. Also Suitable from Unit and Brand 6050
The bowls are suitable from the Dex40 pressure cooker and from the Brand 6050
Question: Why does the temperature on the display run in the Heating and Simmering modes? The staff does not keep the set temperature?Answer: Shteba's pressure cooker keeps the temperature with an error of + \ - 1 degree.
A temperature test was carried out, which can be viewed at this link
Temperature Test The display shows the readings of the temperature sensor.
In steam mode, spray is emitted from the black valve. This is normal?Answer: Yes, when the valve is open, in steam mode, splashes can fly. This is normal.
The pressure cooker emits a squeak in the modes Roasting, Steam, Heating, and Simmering. Is this normal and what does it mean?Answer: In Fry mode, the pressure cooker beeps when it reaches its maximum temperature and starts counting down.
In Steam mode, the pressure cooker beeps when the black valve is closed. This is normal as the Steam mode is intended for use without pressure, those with an open valve.
In Preheat mode, the pressure cooker emits a squeak when the temperature is over 100g and the pressure cooker is under pressure.
In Simmer mode, a squeak is emitted when the pressure cooker is under pressure.
How to disassemble and assemble the valve
How to disassemble the lid of a Shteba pressure cookerhttps://mcooker-enm.tomathouse.com/index.php@option=com_smf&Itemid=136&topic=278949.0How the Steba pressure cooker works
I decided to check if it is possible to fry in Shteba (I have DD1) in modes with pressure, but without a lid, that is, without pressure in the bowl.
In principle, Shteba fries well on the regular Frying program, the heating temperature there is about 170 degrees, but there were questions from users whether there is a possibility of more intense frying.
So - the first experience.
To control that the heating element is turned on and a voltage of ~ 220V comes to it, I unscrewed the metal lid at the bottom of the pressure cooker and connected an ordinary incandescent lamp in a cartridge with wires to the terminals of the heating element. So it is very clearly visible - the heating element is on or off. The staff and the bowl were at room temperature - I didn't cook, I didn't turn on for two days. To control the temperature, I used a thermometer bought on Ali - like this, TP101:
Usually, how is it recommended to fry in Stebe? Pour some oil into the bowl, turn on the Roasting program and wait for the warm-up signal - then the countdown will start on the display.
So I did. I poured the rust into a stainless steel bowl. oil to cover the bottom by 1 to 2 mm. I turned on the Kasha program with the default parameters - 0.7b, 10 min.
After the start of the program, my light came on, heating started. After 4 minutes (it was detected by the kitchen electronic timer, which started immediately after the start of the program), the oil in the bowl was heated to 180 * C, which is more than in the Frying mode, the heating continued. Smooth(!) after 5 minutes the relay clicked, my light went out, which means that the heating element turned off. Nothing lit up on the top line of the display (in the sense, pressure symbols 0.7b). The oil had a thermometer temperature of 216 * C, and the temperature continued to rise. I didn’t have time to notice whether the countdown had started, such a high temperature confused me. I turned off the Porridge mode and turned on the languor mode - a button with a drawn thermometer. The light bulb (and the heating element) turned on for one second and went out. On the top line, I saw 220c - this is a very high temperature for a pressure cooker; inside, in the case, thermal fuses are installed to operate at 142 * C. Therefore, I quickly took out a bowl of hot oil, and inserted a spare Teflon bowl into the Shteba body, poured some water to cool the heating element as soon as possible.
What conclusion follows from the first experience ...
Apparently, the developers have laid down in the algorithm for the operation of programs with pressure a continuous five-minute heating of the heating element, without control from the built-in temperature sensor. The goal is to build up pressure as quickly as possible, but for this you need water in the bowl, which turns into steam and a closed lid with a closed valve. If, after 5 minutes, the thermal sensor detects a critically high temperature, the heating element turns off.
The second experience.
The pressure cooker is cold. A bowl of butter, too, to room temperature.
Now I took three small potatoes, peeled and cut into cubes. Enabled by default, Porridge, 0.7b 10 min. I did not wait for warming up, I put potatoes in the bowl, practically in one layer at the bottom of the bowl. The temperature did not rise so quickly now, this is understandable. Like any food, the pot contains moisture, that is, water, which is a good heat sink for the bowl and heating element. He began to measure the temperature when the potatoes began to crackle in oil.After three minutes (on a separate timer), the oil between the potato slices showed 110 * C, after 4, and after 5 minutes - about 120 * C, and - lo and behold, the heating element did not turn off after 5 minutes, but continued to warm up continuously, my light was on ! And the more rosy the potatoes became, the more the oil in the bowl heated up. It's clear that the water was evaporated from the potatoes. And the heating element kept heating and heating ...
As a result, exactly 14 minutes later, the potatoes acquired a ruddy and very appetizing look, then they would simply burn. Turned it off. The thermometer showed 186 * C, and when turned on for languor, the display saw 190 * C. The heating element was heating continuously. On the top line, nothing lit up On the bottom line, they glowed sadly at 0:10 ...
Conclusion from the second experiment.
With food in the bowl, heating of the heating element when the program is running with pressure (and with an open lid) is not so critical, since the evaporated water carries away heat, providing heat removal. The pressure cooker simply works like a 900 W electric burner. Frying is quite possible. At the end, the temperature is even higher than in Frying mode.
Third experience.
What is a pressure sensor for? It's at the bottom of the pressure cooker and I've shown it before.
He waited again for the bowl and Shteba to cool down.
I take an empty stainless steel bowl. He put on the lid, but removed the valve. The metal cap at the bottom is unscrewed. He tilted Shtebu back at an angle of about 45 degrees, rested against the wall. I turn on the Porridge mode, by default.
Without waiting for something there to get very hot, I open the contact with a screwdriver slipped under the pressure sensor plate. The relay immediately clicks, the heating element and the light bulb connected to it are turned off. On the top line of the display, 0.7b lights up and the countdown begins! This can be seen from the way the colon blinked at 0:10 and the LED next to the Kasha button blinked. Moreover, the restoration of the contact again turns on the heating element, and opening the contact of the pressure sensor turns off the heating element.
The heating element itself is switched on using an intermediate relay on the power board, but this relay is controlled by the microcontroller, it is he who analyzes the state of the sensor contact. And let's take into account that the temperature at the thermal sensor in this experiment was far from that which would be with superheated steam with a pressure of 0.7b, not 115 * С! On / off This did not affect the heating element in any way.
Conclusion from the third experiment. Using a pressure sensor (in modes with a pressure of 0.7b), heating of the heating element is controlled, that is, it is turned on / off to maintain the standard pressure in the bowl. This is provided mechanically - when the pressure is typed, the silicone seal ring expands like a wedge between the lid and the body, the bowl presses on the heating element and they move downward relative to the body literally by a millimeter or a little more. Then the contact, which is mechanically connected to the heating element, opens and this leads to the disconnection of the heating element. Having cooled down a little, the pressure in the bowl drops a little, the contact is restored and the heating of the heating element turns on.
The fourth experience.
In the switched off pressure cooker, I put a cardboard box under the sensor contact - I opened the contact. I turn on the pressure cooker in the network - on the scoreboard, as expected, lines. But turning on any mode does not work at all. The buttons do not respond in any way.
Usually, in other pressure cookers of other manufacturers, when the pressure sensor contact is lost, the E4 error signal is displayed on the display. Shteba doesn't have that. The modes just do not turn on.
P.S.
If that - I have a 2012 Steba DD1 Eco, as I understood from the sticker on the bottom (there are such numbers: 9-12 / 2012)
