How to Fix the LC Error Code on Your Samsung Dishwasher
A blinking “LC” error code in your Samsung dishwasher might just puzzle you, but you are not alone. Sometimes, it may strike when you least expect it, thus messing up your daily schedule. Fortunately, this post will help you understand what the LC error actually is and how you can resolve it yourself, step by step.
What Does the Samsung Dishwasher Error Code LC Mean?
The “LC” error code means your dishwasher is detecting a leak. It’s a kind of safety feature to help prevent water from damaging your home or internal mechanisms. In other words, all it really means is if the dishwasher detects moisture in its leak sensor, it automatically shuts down to prevent further damage from occurring.
Fortunately, while that sounds like a big problem, the underlying cause is often something minor that you can fix yourself without needing to call in a technician.

Common Causes of the LC Error Code
Here are some of the common causes for which the LC code may appear:
- Actual Water Leaks: There might be a leak in the plumbing, hoses, or connections of the dishwasher.
- Excess Moisture: Sometimes, leftover water from a cycle or condensation can trigger the error.
- Incorrect Installation: If a dishwasher has not been properly levelled or the parts are weakly connected, this could lead to leakage.
The wrong kind of detergent and excessive soap results in an overflow of suds, which causes the leak sensor to activate as well. By understanding what was the cause is the first way to fix it. Now, let’s have that dishwasher running again!
How to Fix LC Error Code on Your Samsung Dishwasher
Practical ways of troubleshooting and fixing the LC error code are enumerated herein:
1. Switch Off the Dishwasher
First things first switch your dishwasher off and pull out the plug from the power socket. If you can’t find the plug, switch off the circuit breaker. Safety first!
2. Let the Extra Moisture Evaporate
Sometimes, the LC error can easily be fixed by allowing the air to dry out your dishwasher. Here’s how:
- Open the door and clear everything out of the dishwasher, including racks and utensil trays.
- Dry the visible water inside the machine, especially at the bottom and around the drain area, with a towel.
- Tilt the dishwasher to one side to drain any water that may be caught inside.
- For optimal results, leave the dishwasher open for a few hours to air dry. This can help reset the leak sensor.
3. Look for Leaks
Look carefully in these areas for possible leaks:
- Hoses: Inlet and drain hoses should be checked for any cracks or loose connections. Tighten the connections if necessary or replace damaged hoses.
- Dishwasher Door Gasket (Seal): A damaged or worn-out door seal may allow water to seep out. If the seal looks compromised, it needs to be replaced.
- Tub and Interior: Check the interior for any visible damage.
If there is standing water beneath or around the dishwasher, thoroughly mop it up before proceeding.

4. Use the Correct Detergent
If excess suds were the cause of this error, now is the time for a reevaluation of your detergent. Be sure to use a dishwasher-specific detergent. If the problem has been suds, put a cup of vinegar in the bottom of the machine and run a rinse-only cycle through to clear out the suds.
5. Reset the Dishwasher
After addressing possible leaks and drying out moisture, you’ll need to reset your dishwasher. Here’s how:
- Plug the dishwasher back in or flip the circuit breaker on.
- Hold down the “Start” button for 3-5 seconds to reset the machine.
This simple reset can often clear the LC error code.
6. Level the Dishwasher
Use a level tool to ensure that your dishwasher is perfectly aligned with the floor. If it’s tilted, adjust the leveling legs to stabilize it. This can prevent unintended water pooling.
7. Still Seeing the Error? Call for Backup
If you’ve tried all these steps and the LC code persists, it’s time to call a professional. There might be a more serious issue involving internal components that require expert attention.
Pro Tips to Avoid LC Errors in Future
Prevention is the best medicine to keep your dishwasher running. Here’s how you can keep this LC code at bay:
- Regular cleaning of the filter and drain prevents blockages from building up in them.
- Don’t overload the dishwasher, as it may lead to poor drainage and leaks from the appliance.
- Use only good quality dishwasher-safe detergents.
- Schedule routine maintenance to catch potential issues before they happen.
