Samsung Dishwasher Diagnostic Mode Explained

Like every other technological appliance, Samsung dishwashers run into problems. The problem might arise during or after an operation. It’s never a good feeling when your dishwasher stops working, leaving you clueless and frustrated.

Your dishwasher might malfunction because of a user-related problem or system malfunction. Samsung saw the need to include an automatic electronic diagnostic mode in this appliance. Rather than seeking the help of a technician or professional immediately, this feature might help you troubleshoot the problem.

What is a diagnostic mode? How can you enable it? How can it help you?  This article will answer all these questions and other related ones.

Samsung Dishwasher Diagnostic Mode: What Does It Mean?

The automatic electronic diagnostic mode is present in most Samsung dishwashers. This feature helps users troubleshoot appliance problems. It runs a set of tests on your appliance to detect where the problems lie.

It searches for the dishwasher problem and corrects them when it detects any. During the diagnostic process, all the system functionality will be scrutinized to ensure they are working appropriately

The aim is to fix anomalies in the system, especially the minor ones, or communicate where the problem lies if it’s a complex one by displaying an error code. This will help the user investigate the cause of the problem and fix it accordingly.

For instance, it can help fix problems such as abnormal blinking lights or other trivial error codes the system encounters. Simply put, this feature is the first aid operation of the dishwasher. Other complex diagnoses can then be attended to accordingly.

How do you set your Samsung dishwasher into a Diagnostic Mode?

How To Start The Samsung Dishwasher Diagnostic Mode

The method to set Diagnostic Mode on Samsung dishwashers may vary across models. However, there’s a general method that works for most models. You can run the diagnostic mode on your Samsung dishwasher with the simple steps below:

  • Switch on the Power unit
  • Press and hold the Start/Delay button on the control panel until the display screen show “17H.”
  • Similarly, press and hold the High Temp button till the display screen also show “AS.”
  • Then, press the Start button
  • The system should immediately start the test cycle. You’ll see the time counting on the display.

Sit back and allow the Self-Diagnostic Mode to run successfully and fix system anomalies. If it doesn’t detect any problem with the system, i.e., all functions are working appropriately,  the system will display the symbol “0t” on the screen.

The “0t” symbol denotes 0 time left which means the tests have successfully run and no error was detected.

However, if the screen displays an error code, the test communicates the function/part that’s malfunctioning. Your job is to investigate the problem and seek to solve it. Error codes in dishwashers have meanings and are pretty easy to fix, provided you can interpret them.

For example, the 1E or IE error code indicates a clogged filter error. It signifies that water is not flowing from the filter. You can quickly fix this by cleaning the filter appropriately using the user manual.

In some cases, the errors are complex and demanding. You might need the help of a technician to solve the problem, especially if it’s related to broken or faulty components.

Samsung Dishwasher Error Codes

If the test cycle returns an error code, you’ll be safer if you can interpret what the error code denotes, or else the operation will be futile. Samsung dishwasher error codes are represented by the combination of a letter and figure, e.g., 1E, 9E, 3C, 5C, e.t.c.

These errors are relatively easy to fix without the help of a pro. However, if you don’t understand the meaning, what’s supposed to be a quick fix becomes a rigorous exercise. Below are some common error codes in Samsung dishwashers and what they denote:

  • Error code 1E, IE: Clogged filter
    • Fix == Cleaning the drain filter
  • Error code 3E: High-temperature water supply
    • Fix == lower the temperature manually by setting it below 80°C
  • Error Code 3C: Pump operation error
    • Fix == Repair or replace the pump
  • Error code 4C, 4E: Water supply problem
    • Fix == check water inlet hose and water pressure. Ensure the hose is not clogged and the water pressure is enough
  • Error Code 5C, 5E: Drain problem
    • Fix == check drain components such as drain hose, filter, and pump. Clean and unclog them
  • Error code OC, 0C, oE: Over level water problem
    • Fix == Check water inlet and drain components. Clean the drain, pump, and filter.
  • Error code CE: Communication error
    • Fix == restart the dishwasher
  • Error code HC, IE, 1E: High-temperature heater
    • Fix == Unplug the dishwasher for a minute before restarting it. Empty the dishwasher, put the standard detergent quantity, and run a new cycle.

Many other error codes might arise in a Samsung dishwasher, but the above are more prevalent. In cases where you can’t denote the problem source, you should seek the help of a technician.
