Samsung Dishwasher Error Code 7E – Causes and Easy Solution

First of all, you need to clear the misconception between the error codes 7E and E7 (both appear on Samsung Dishwashers).

The 7E error code usually displays on the screen after the washing cycle has been started and it indicates an issue with the WaterWall system of the machine, which means that the machine is having an issue with the proper distribution of water during the washing cycle.

On the other hand, the E7 error code is an implication of a faulty thermostat.

Causes of the E7 Error Code

The main cause of the E7 error code on Samsung dishwashers is a faulty WaterWall system, which could be due to any of the following components:

  • Motor
  • Sensor
  • Disperser

How to Fix Error Code 7E

Start by resetting your Samsung dishwasher. This helps if the error had been caused due to a glitch. If this doesn’t work, follow the below-mentioned steps:

  1. Open your Samsung dishwasher and see if there are any usual objects that might be disturbing the flow of water. Take it out and run a test cycle.
  2. Next, locate the disperser and make sure that it is fixed correctly in its place. If the sign of the WaterWall system is upright, it means that there are no issues with the disperser.
  3. If the sprinkler is causing this issue, you will probably hear unusual sounds during the washing cycle.
  4. Once you have checked these parts, locate the sensor and examine its contacts. Also, clean it thoroughly. Consider replacing it if it is in a bad state. You can check its credibility by using a multimeter to check its detector.

If none of the above works, I’d recommend getting in touch with Samsung’s official support.
