Samsung Dishwasher LE Code? (here’s why & how to fix it)

If your Samsung dishwasher is displaying the LE error code and is failing to operate it can be frustrating. You are probably expecting a huge repair bill but that’s not necessarily the case.

The LE error code signifies that your dishwasher has detected a leak or more specifically, there’s water in an area where it shouldn’t be.

In this article we’ll take a close look at the Samsung dishwasher LE error code and offer ways to solve this annoying issue. Some of these solutions can be carried out at home by anyone with just a slight DIY ability.

How To Clear The LE Error Code

The first thing to try is a reset which will reboot the dishwasher and is effective if the error code is caused by a glitch in the system. All you need to do is;

  1. Disconnect The Power Supply
    You can disconnect the power supply by removing the plug from the wall socket or flipping the switch on the circuit breaker to the off position.
  2. Allow 10 to 15 Minutes To Pass
    This gives the power time to clear the system allowing the appliance to reset.
  3. Reconnect The Power Supply
    After the allotted time period has passed, reconnect the power supply. The error code should have gone and the dishwasher should operate properly once again.

If the error code remains after resetting the appliance or reappears soon afterwards, the problem wasn’t caused by a glitch and you will need to investigate further.

Let’s take a closer look at each of these problems;

Loose Or Damaged Inlet Hose


If you can see the leak, it’s most likely to have been caused by a loose hose or weak connection. The first place to check is the inlet hose, which is the way all of the water used in the dishwasher enters the appliance.

Inspect the inlet hose for any cracks or damage and check that the connection (where the inlet hose is attached to the dishwasher) is tight and not leaking. 

If the inlet hose is damaged in any way, it will need to be replaced.

Defective Water Inlet Valve

All of the water that enters the dishwasher comes through the  inlet valve which is controlled via the control board. Over time, the inlet valve can become damaged and start to leak.

Or it could continue to allow water to enter the dishwasher even when the control board tells it to stop. This will lead to a build up of water which will trigger the LE error code.

The inlet valve will need to be checked and if it proves to be faulty, it will need to be replaced.

Defective Pressure Switch

The pressure switch detects changes in the air pressure in the tub as it fills with water. This sends messages to the control board which then knows when to shut off the inlet valve.

The pressure switch can become stuck which can cause either too much or not enough water from entering the dishwasher. Too much water entering would trigger the LE error code.

You will need to get the pressure switch checked and replaced if found to be faulty.

Loose Or Damaged Drain Hose

All of the water that leaves the dishwasher does so via the drain hose. This is another part that could be the cause of any leak. Check that the drain hose isn’t damaged and that the connectors are tight and not showing any signs of water leakage.

This could be from the dishwasher end or the drain pipe end, try tightening both ends. If the drain hose is damaged, it will need replacing.

Defective Float Switch

The float switch is located on the bottom of the tub and is designed to communicate with the control board when there is enough water present to wash the dishes.

What happens is that as the water fills the tub, the float switch lifts up and gets to a set point then sends a message to the control board that the tub is full.

If the float switch becomes defective, it could fail to notify the control board which will keep the water flowing. This leads to a leak which triggers the LE error code. You can check the float switch by gently lifting it and listening for a click.

If you hear the click, the float switch is working correctly, if there is no click, the float switch will need to be replaced. You can do this yourself after removing the lower front panel, but we recommend getting a technician to do this for you.

Dishwasher Unlevel

If the dishwasher is not level, it could cause the door to not create a waterproof seal when the door is closed. Alternatively, if it leans to one side even slightly, it could cause water to pool in the base of the tub.

That water would eventually leak out from any gap it can find, typically around the door.

You need to ensure the dishwasher is level using a spirit level. Check front to back and side to side. You can adjust the level using the adjustable feet on the dishwasher.

Misshapen Tub

In some cases, the dishwasher could be screwed too tightly to the cabinet which can cause the tub to be overstretched or distorted. This distortion can lead to gaps which allow water to flood from the appliance.

You can try adjusting the screws yourself or contact a technician to do this accurately for you.

Waste Disposal Unit Blocked

If your dishwasher is connected to a waste disposal unit and it has only just been installed, the leak could be due to an installation error. Inside the waste disposal there is a cap that needs to be removed before connecting to the dishwasher’s drain hose.

If that cap is still in place, the waste water from the dishwasher cannot enter the waste disposal which would cause it to leak. If you had the waste disposal unit fitted professionally, you will need to contact the technician or plumber and get them to complete the installation by removing the cap.

If, however, the waste disposal unit has been there for some time, it could have become blocked. Try running it for around 20 to 30 seconds to clear any blockage.

If it’s still blocked, you can often free any blockage manually by placing the correct allen key into the socket on the disposal unit and turning it backwards and forwards until it moves freely.

Air Gap Blocked

If your dishwasher is connected to an air gap, this could have become blocked which would eventually lead to the dishwasher leaking. The air gap is designed to prevent waste water from returning to the dishwasher.

It does this by separating the waste water from the drain. What happens is the waste water from the dishwasher falls through a gap once it leaves the drain hose before entering the waste pipe.

Over time this gap can become blocked with food waste, fat, grease or even limescale. This can allow waste water to travel back into the dishwasher, triggering the LE error code.

You will need to inspect the air gap by removing the cover and plastic cap. Then remove any blockage you find using a pair of tweezers. You should then use a bottle brush to clean as far into the tube as you can.

Using Too Much Or The Wrong Type Of Detergent

Detergents can cause moisture, which could cause the LE error code to appear. If you use too much detergent, some will remain in the dishwasher’s system.

Worse still is using the wrong type of detergent, you should only ever use detergent specifically formulated for use in dishwashers. If you were to use washing up liquid for example, the dishwasher would be full of soap suds.

Those suds could trigger the LE error code and in some cases even cause an actual leak.

If you do find excessive soap suds in the tub of your dishwasher, try pouring 10 ounces (284 ml) of milk into a bowl and placing the bowl on the top rack of the dishwasher.

Run a short wash cycle and you will find all of the soap suds will bind with the milk and get washed away.

Door Gasket Damaged

The door seal or gasket can become damaged over time especially if you don’t regularly clean the dishwasher. Any damage in the door seal can cause a leak and trigger the LE error code.

The door seal should be cleaned at least once per month and inspected regularly for any damage. If it is damaged, it will need to be replaced.

Spray Arms Clogged

The water that washes your dishes comes through the spray arms. If the nozzles on the spray arms become clogged, the water could be redirected towards the door. This could lead to leakage and the triggering of the LE error code.

The spray arms should be removed once per month and cleaned in warm soapy water or a solution of warm water and distilled white vinegar (50/50 mix). Inspect the nozzles and remove any blockages carefully using a wooden toothpick. Ensure that you prise the obstacle out of the nozzle and don’t force it in further.

Water Reflector Blocked

On Waterwall models, the spray arms are replaced with a water reflector which combines high pressure water jets with an angled bar which slides backwards and forwards directing a powerful “wall” of water through the dishwasher to clean the dishes.

If the reflector becomes clogged or blocked it could trigger the LE error code and will need to be cleaned and any obstructions removed.

Detergent Dispenser Damaged

Over time, the detergent dispenser could become weakened and damaged. This could lead to the incorrect dispensing of the detergent.

Which could trigger the LE error code and is best checked and replaced by a technician.

Clogged Or Damaged Filter

The filter traps food particles and other debris and prevents them from damaging the pump or flowing back onto the clean dishes. If the filter isn’t cleaned regularly, it can cause a blockage preventing the waste water from leaving the appliance.

This would be enough to trigger the LE error code. You should clean the filter at least once per month to prevent any unnecessary blockages. 

In some cases, the filter can become damaged which can cause similar issues. Inspect the filter and if it is damaged, it will need to be replaced. 

You will need to know the serial number of your appliance when ordering the replacement part to ensure you get the correct one.

Defective Water Pump

The water pump is an integral part of the functionality of the dishwasher. It pushes all of the water through the appliance and could become clogged or damaged over time.

If it becomes defective, the water pump could cause water to pool inside the tub which will eventually leak out triggering the LE error code.

We recommend getting a technician to inspect and replace the water pump if necessary.

Defective Control Board

The control board sends and receives messages to and from every component on the dishwasher. It can sometimes develop a glitch which can be cleared by resetting the dishwasher (as stated above).

However, in some cases, the control board could become defective. This would lead to it sending the wrong messages to various parts of the appliance and could trigger the LE error code.

The control board is a delicate component, which is why we recommend getting a technician to inspect and replace it if necessary.

Ways To Prevent The LE Error Code From Being Displayed On Your Samsung Dishwasher


Once you have successfully removed the LE error code from your dishwasher, there are a few things you can do to prevent it from reappearing. Which include;

  • Run The Dishwasher Regularly
    Running the dishwasher on a regular basis can prevent the buildup of stagnant water which can lead to mould and mildew growth. If you don’t use the dishwasher very often, run a hot service wash at least once per month to prevent any problems. 
  • Have A Regular Cleaning Schedule
    Your dishwasher should be cleaned at least once per month. This includes cleaning the filter, spray arms and nozzles and door seal.
  • Run A Hot Service Wash Once Per Month
    You should run a hot service wash in the empty dishwasher at least once per month. You can use a commercial dishwasher cleaner or a bowl of white vinegar placed on the top rack.
  • Never Overload Your Dishwasher
    Overloading the dishwasher can put undue strain on many of the components. This will lead to excessive wear and tear and eventually cause the dishwasher to break down. Always follow the manufacturers guidelines which can be found in the user manual.
  • Only Use Approved detergents In The Correct Quantity
    Consult your user manual for the Samsung approved dishwasher detergent and never use anything else. These appliances are designed to work at their optimum best using that approved detergent. You should also never use more detergent than is recommended.

By sticking to these recommendations, your dishwasher should give you years of trouble free service.
