The programmed pressure cookers are suitable for everyone who doesn’t have time to cook for hours. This is because these pressure cookers can cook quickly without impacting the meal’s taste and texture. However, the Mueller pressure cooker E4 error can be pretty frustrating but we have the troubleshooting methods in this article!
Mueller Pressure Cooker E4 Error
1) Gasket
First of all, the placement of the gasket needs to be apt for ensuring that the E4 error goes away. In this case, you need to take off the lid and remove the gasket. After some time, put in the gasket again. Secondly, keep in mind that the gasket must be properly cleaned and shouldn’t have any dirt. In addition to dirt, you need to clean up the grease as well. Once the gasket is clean, seat it in the lid again and the error will be fixed.
2) Contact Points
When the E4 error appears on the pressure cooker, it’s mainly because there is no contact on the pressure switch (the sensing switch) at the bottom’s edge. For resolving this issue, you need to take out the switch and use sandpaper for cleaning the contact points. Once the contact points are clean, the E4 error will go away.
In addition, you could also try cleaning the contacts. For this purpose, you need to take off the bottom plate of the pressure cooker and clear up the tabs. You need to take off the switch (it will have two blue wires), so clean these contacts and insert them again.
3) Container
When there is an E4 error on the Mueller pressure cooker, the users need to ensure that the inner container is dry. We suggest that you use a dry cloth for wiping the moisture. However, you need to ensure that the pressure cooker is switched off while you clean the container. All in all, once you’ve cleared the moisture, switch it again and cook as you like.
Secondly, the users need to ensure that you have cleaned the pressure cooker. That’s to say because dirty pressure cooker or containers can lead to E4 error. That being said, whenever you cook, always clean the bowl thoroughly and let it dry before starting cooking.
4) Lid
Believe it or not, the lid plays an essential role in optimizing the cooking performance. With this being said, the users need to ensure that the lid of the pressure cooker is closed down properly and tightly. In simpler words, the errors can be provoked by incorrect closure. So, before you set the cooking mode, tighten up the lid.
5) Placement
The placement of the pressure cooker matters a great deal. On the contrary, the incorrect placement of the pressure cooker will adversely impact the cooking (yes, it can lead to errors). For this purpose, we suggest that you place the pressure cooker on a solid and flat surface and try again.
6) Valves
The valves of the pressure cooker must be cleaned and working properly. In this case, we suggest that you check the bypass valve and make sure it is cleaned up. Generally, it’s best that you clean the valve by washing it. We don’t recommend using the cloth for wiping it dry because it might leave behind some particles.
