Samsung Dishwasher Low-Level Water Error! (5 Possible Reasons)

Although Samsung dishwashers are one desirable appliance, they’re still liable to abnormal occurrences. That’s why you may sometimes notice a low-level water error.

Ideally, different error diagnoses imply disparate issues. Thus what does the low-level water error suggest? What does it communicate?

The low water error typically signifies insufficient water in the machine. This error can show up when the water level sensors malfunction and convey the wrong information. It’s such that even when the water level is high, the sensor may interpret it as low. But there’s likewise a chance that components like the inlet valve and control board are faulty.

This article reveals deep insights into the low-level water error, explaining the circumstances under which it can surface and the possible fixes. 

The aim is for your dishwasher to be fully functional and operate as desired, so hang around.

What Does the Low-Level Water Error Indicate on a Samsung Dishwater?

Samsung Dishwasher Low-Level Water Error

The low-level water error warns that the dishwasher is running out of water and needs refilling. 

This error is typically displayed as 9E using lights on the unit’s front panel; thus, its alternative name is the 9E error code.

Error codes are essential because they assist you in detecting the problem before contacting a professional or customer care service. 

On the other hand, understanding the message of each code on your Samsung dishwater is likewise significant- by doing so, decoding will be easy. 

So here are some other error codes and their meanings.

Error CodesMeaning 
1E(clogged filter error) Water isn’t getting through the filter.
3C(pump inefficiency error) The water pump isn’t functioning.
3E(overheating error)The water is extremely hot.
4C\4E(water supply error) There’s an inadequate water supply at the required temperature.

The table above shows that although a few codes share matching denotations, each has a unique interpretation. 

Subsequently, the low-level water error is one you shouldn’t ignore. It’s usually a result of many factors and occurrences. 

Some include a defective water level sensor, a faulty water inlet valve, a malfunctioning float assembly, a defective float switch, and an impaired control board.

#1. A Faulty Water Inlet Valve

Usually, the inlet valve supplies water to the dishwasher. So If it’s defective, there’ll be less or no water in the machine, and as a result, the low-level error will display. 

In most cases, the valve may not open up, causing water flow restrictions. Obstructions like dirt can clog the valve filter screens and prevent water flow.

#2. A Defective Water Level Sensor

Another reason for the error display could be a defective water level sensor. 

Practically, the water level sensor detects the water level and communicates the result to the control panel. But sometimes, it can get faulty and convey the wrong information

It’s always such that even when the water isn’t low, it will convey a low-level water message, prompting the 9E error to show up.

#3. A Malfunctioning Float Assembly

Though it doesn’t always occur, a malfunctioning float assembly can also prompt the error display. 

Typically, water in the tub rises with a float when there’s a water supply. This float functions in halting water flow when it reaches the regulated desired level.

But unfortunately, the float could sometimes remain stuck in an undesirable position and halt water flow, preventing the washer from filling. 

#4. A Defective Float Switch

The float switch works hand in hand with the float. It’s such that when the float reaches the set or desired level, it signals the float switch to shut off the water flow. 

Thus, assuming the switch is defective, it’ll misinterpret the signal or go off at the wrong time.

#5. An Impaired Control Board

As you may know, the control board is like the dishwasher’s central processing unit. Many abnormalities can occur if there’s a burn around the board or some parts are inoperable. 

There won’t be effective communication with other components like the inlet valve and float switch; this will cause the underfill scenario. Altogether, the low-level water error will display when the above factors surface.

Subsequently, some solutions to the problems are in the table below.

How Do I Fix the Over-Level Water Error on My Samsung Dishwasher?

It’s common for your Samsung dishwasher to have water leaking from the bottom. This usually occurs when there is too much water in the dishwasher. 

Since it’d be seemingly worrisome to frequently reduce the water manually, knowing the fix and resolving the issue at once is the best option. 

Some fixes to resolving the over-level water error in your Samsung dishwater include:

  • Check the drain hose and ensure it’s in good working condition
  • Unclog the sink drain
  • Effectively clean the dishwashing machine

#1. Check the Drain Hose and Ensure It’s In Good Working Condition

One helpful fix is examining the hose and ensuring it’s in place. Sometimes, during installation, the installer may forget to insert a high loop, resulting in the wastewater returning to the machine

So, ensure that the high loop fixture is available in the hose setup. Additionally, the hose may incline downwards or wear away due to an extended usage period. In such cases, it’d be best to replace the hose.

#2. Unclog the Sink Drain

Not just specific to Samsung dishwashers, and clogging occurs easily in other appliances. This hindrance prevents water from flowing out; consequently, the over-level water error will display. 

To unclog the sink, remove the stagnant water from the sink. Then, run hot water through the sink or utilize vinegar and baking soda.

#3. Effectively Clean the Dishwashing Machine

Clogs usually come up due to the build-up of leftovers and food remnants- they don’t just occur once. 

So, cultivate the habit of constantly cleaning the dishwasher and not waiting until you experience issues. Frequently cleaning ensures a fully functional dishwashing machine.

How Do I Clear Error Codes on My Samsung Dishwasher?

Clearing any error code on your Samsung dishwasher isn’t a complex task. All you need to do is decode the error, i.e., what it indicates, then sorts ways to fix the cause.

You can consult the manual for various error codes and their indications. But if you’ve misplaced yours, kindly navigate to the Samsung site

There, you’ll find all the possible error codes that are likely to show up and their meanings. You’ll also find the possible causes, which will be very useful in fixing the error.

By knowing the factors responsible for the errors, you’ll be able to determine which part of the dishwasher is causing the issue. 

Afterward, inspect the possible affected areas and see if there’s a need for replacement. You should contact a professional to help you with the retrofitting, especially if you aren’t up to the task.

Additionally, resetting doesn’t always come in handy, but you can try it too. The most effective option is figuring out the implication of the error code and the possible causes, then resolving them.

Notwithstanding, to perform the reset, disconnect the machine from any power source, let it sit for a while, and reconnect it back.

Where Is the Water Level Sensor on a Samsung Dishwasher?

The location of the sensor may differ depending on the model. Nevertheless, you’ll generally find the water level sensor at the bottom end of the machine. 

It’s usually in a plastic covering at the side of the machine and helps detect the dishwasher’s water level. 

It’s such that when there’s insufficient water, it’ll convey the message to the circuit board to display the error message.

Overall, the sensor is important because it prevents the dishwasher from running when there’s inadequate or meager water.


#1. What Exactly Does the OC Symbol on My Samsung Dishwasher Mean?

The OC is an error code that tells you that there’s too much water than required in the machine. This error code usually displays when there’s a water flow restriction in the system.

#2. Why Is My Samsung Dishwasher Saying LC?
