Whatever may be the case but whenever you are confronted with an error it’s never a good feeling. Right? Similarly, even in the case of Samsung Dishwashers, one such error which has been infamous for making the rounds every now and then is the Error Code 7E

In the following article I will be discussing everything there is to know about the particular error as well as primarily discuss all the different ways out there with the help of which you can get rid of the error in no time.

How to fix Error Code 7E in Samsung Dishwasher?

Today, with the advancement in technology, most machines themselves are able to indicate what might be wrong with them and ask users to take actions accordingly.

Even in the case of a Samsung Dishwasher, just by looking at the error message being displayed on the screen, the end user might be able to tell what might be the cause and take necessary actions to fix it.

So, when you have the 7E Error Code flashing on your Dishwasher display screen, there are a few things you should automatically be able to consider:

  • Primarily, when we are talking about the 7E Error Code. Then it usually has to do something with the water dispensation unit and problems related and revolving around it. 
  • The water dispensation mechanism unit comprises a number of sub-units such as the sprayer unit, the rail unit, sensor units and also the motor unit. 
  • And thus, if anything goes wrong with any of the units as mentioned above. Then the dishwasher surely will display the 7E Error on its display screen.

Now, depending upon the intel gained from the above points and having to know where to look and what to fix when confronted with the 7E Error Code.

I guess we can finally head to the part where we look at the various reasons in detail as well as how to solve such issues in order to get rid of the error code. 

1. Problem with the dispenser

If a problem is present in the dispenser system and the dispenser is unable to spray any water from its sprayers, then this may typically result in the e7 Error Code to pop up. 

In such cases, the very first thing you must do is look out for any possible utensils or appliances inside the machine which may cause the moving boom to stop.

And if there is anything present as such which is stopping the boom from moving, then you must first turn off the device completely and next redistribute the appliances correctly so that they do not block the lower rocker and boom.

Once that is done, try starting the dishwasher once again and see if the error is still there. 

There are also occasions when the dispenser itself is not properly installed. In such cases too the dishwasher may display the following error.

To solve this issue, all you need to do is raise and remove the bar. Then, turn the reflector and attach it to the grey shuttle which is present in the guidance system.

After all that is done, place the bar back to its original position and WaterWall logo to appear, indicating that the dispenser has been installed properly.

2. Problem with the spray arms

There may be occasions when the packing tapes used during packaging and transportation of the appliance may result in blocking the movement of a component.

In such cases if packing tapes are still present inside the dishwasher, stopping the movement of components such as the spray arms from revolving. Then the dishwasher may display the following error.

Hence, to solve this problem, you will first need to obviously turn off the device completely and then peel off any kind of adhesive tapes that may be stuck on any component inside the unit.

And once you are completely satisfied that all creeks and sides have been carefully checked and taken care off, you may start the initialization process once again and see if the error still persists.

3. Problem with the sensors

Every modern digital appliance more or less is primarily dependent upon sensors for functioning correctly. Similarly, even in the case of the Samsung Dishwashers, if there is any problem with the sensors or their respective circuits, then such an error may occur. 

In order to solve errors resulting from damaged sensors or their circuits, one must first know which sensor inside the dishwasher is acting up.

Whether it is a sensor that is damaged or there is a loose circuit within the system which is not letting the sensor to work properly.

One must first check all the possibilities and then depending upon the findings, fix either the sensor by replacing it or simply solder the circuit where it may be broken. Once that is done, turn on the dishwasher unit and see if the error still persists.

4. Problem with the Electric motor

Last but certainly not the least, the most important component of the dishwasher that pretty much does all the heavy work is without much doubt the electric motor unit. And if there is anything wrong with the functioning of the electric motor unit, then an error such as 7e is pretty obvious. 

Thus, if the error is caused due to some problem with the motor unit of the dishwasher, then you can follow the steps as mentioned below:

  • Firstly, turn off the dishwasher completely as well as unplug it from the main supply unit.
  • Next, open up the Dishwasher door and remove the lower bar situated below.
  • Then, take the motor unit out from the dishwasher and check the readings from the motor terminals with the help of connecting test probes. 
  • If the multimeter device at the receiving end of the test probes shows the desired results, then there is nothing wrong with the motor unit.
  • However, if the readings are not as expected, then you may have to either replace the whole motor unit or fix any faults in the connections if it’s present.
