The E7 error code signals a problem with the water level sensor. This sensor is crucial for detecting and maintaining appropriate water levels during wash cycles. 

One common warning sign is that the washing machine empties every time you try to start it. In certain situations, it may not even start a cycle at all, in which case a specialist will need to inspect the sensor to detect the issue

The E6 error code indicates a problem with the motor. This means the machine is experiencing difficulties rotating the drum properly. You will most likely notice the washing machine bouncing or shaking throughout a wash cycle if this is the case. This could be caused by a variety of issues, but unlike other error codes, it is best left to a specialist to resolve

The E5 error code indicates that the washing machine has a problem with water drainage. This means that the machine is unable to empty water properly at the end of a cycle which could be caused by a variety of issues ranging from minor blockages in the pump filter to more severe difficulties with the control board. 

So, if you’re confused how to start, enlist the help of an expert.

The E4 error code generally signals a problem with the machine's ability to fill with water. This means it's not filling up with the water and reching the necessary water level to proceed with the wash cycle. 

This could be a simple issue with the door jamming,or it might be a more complicated issue with the water valve or wiring

The E3 error code signifies a heating issue, specifically that there is continuous heating. This means the washing machine is detecting constant heat even when it shouldn't be heating the water. You should inspect the heater’s control board relay, but this is something that should only be done by an expert

This error code indicates that there is a problem with the heater meaning that the machine is unable to heat water properly. This is most likely a wiring issue, which you may be able to resolve with the help of the instruction manual. 

However, I would recommend enlisting the help of an expert.

The E1 error code indicates a heating issue with the NTC thermistor wiring being the major culprit. This component is crucial for regulating water temperature within the machine. 

You can check the thermistor to test the connection on Beko washing machines. At normal functioning, it should register 4700 ohms at 25°C
