You have just bought a Power Pressure Cooker XL. However, you have received an error code E4 which tells you that something has gone wrong. You should check the following to solve the problem. First, check whether the lid is sealed properly. If it is, try to clean the valve with a cloth. This should resolve the error code. If not, contact the customer support and ask them to fix the problem under warranty.
If you are unable to fix the error code E4, you can check the thermal switch or contact points. The thermal switch is located on the bottom plate of the pressure cooker. You can sandpaper these points. Before you do so, make sure to switch off the pressure cooker. Clean the contact points of the thermal switch and thermal point. Clean the points using sandpaper. Once you have done so, clean the circuit and switch it on again.
If the lid is not sealed, it can cause an error code E5 to occur. Also, if the Steam Release Valve is not fully opened, the pressure may be too high. In such a case, you should not use the lid during the Brown/Saute settings. You should also make sure that the valve is set to “Release” or “Open”.
Check the wiring. Sometimes, an electronic board or pressure sensor will show an E4 error. If the wiring is okay, but the device is not heating, then the problem is most likely the pressure sensor. If you have a redmond multicooker, it may also display an E5 error. Lastly, check the overheating protection equipment. If all of the above has failed, you should take it to a service center for a professional checkup.
After resetting the unit, it should work properly again. First, unplug it. This will take a few seconds. Then, you can re-programme the cook settings. Then, start the cooking cycle again. If the problem persists, contact the manufacturer of the power pressure cooker XL. You can also try some other remedies. You can read the user manual to see how you can fix the error.
If the E4 message still persists, you can try cleaning the gasket. If the gasket is clean, the error will go away. Alternatively, you can use water to clean the pot’s interior. In order to fix the E4 error, you must restart the device and restart the cooking program. This may be difficult if you don’t know how to use it. The first step in solving this error is to make sure that you have a reliable recipe.
