Direct answer: A Samsung dishwasher LC or LE code usually means the machine thinks it is leaking because water reached the bottom leak tray. Most of the time the cause is oversudsing, a small door or hose leak, or water splashing where it should not.
Most likely: Start with soap and loading issues, then look for water around the door, filter sump, and drain hose. If the base dries out and the code stays gone, you likely had a one-time leak event rather than a failed part.
Treat this like a real leak until you prove otherwise. Pull the power, dry up any water under the unit if you can reach it safely, and then run a short test while watching for where the first drip or splash shows up. Reality check: a single bad detergent load can trip this code. Common wrong move: clearing the code and running full cycles without finding where the water came from.
Don’t start with: Do not start by ordering a pump or control part. This code is often triggered by suds, a loose filter area, or a drain hose problem.
The dishwasher stops, may run the drain pump, and you find water at the front corners or under the toe kick.
Start here: Check the door seal area, lower spray pattern, and anything that could make water splash past the tub lip.
The machine shows LC or LE and may keep trying to drain, but the kitchen floor looks dry.
Start here: Look for water in the base pan from a small internal drip, oversudsing, or a slow hose seep.
The problem began after using pods differently, adding rinse aid, using dish soap by mistake, or running a cleaning cycle.
Start here: Assume suds first. Excess foam can push water into the base and mimic a leak.
It may happen during fill, early wash, or near drain, and the timing is pretty consistent.
Start here: Match the timing to the likely source: fill-related leaks near the inlet side, wash splashing at the door or spray arm, drain-related leaks at the hose path.
This is one of the most common reasons for LC or LE. Foam lifts water where it does not belong and can trip the leak sensor even when no part is broken.
Quick check: Open the door after the machine stops and look for foam residue, slippery water, or a recent detergent change.
A tall pan, twisted rack, or grease on the tub lip can send spray toward the front corners. A flattened gasket can make it worse.
Quick check: Inspect the door opening for food buildup, check that racks roll in fully, and look for drip marks at the lower corners.
A loose filter assembly, cracked lower spray arm, or debris deflecting spray can throw water where it should not go.
Quick check: Remove the lower rack and inspect the filter area and lower spray arm for cracks, looseness, or heavy debris.
If the code tends to show during drain or shortly after, a hose connection or hose rub-through is more likely than a door leak.
Quick check: Watch underneath during a short cycle if accessible, or check for fresh moisture around the dishwasher drain hose path.
You want to prevent cabinet or floor damage first, and you need to know whether the leak sensor is reacting to leftover water in the base or to a leak that is still active.
Next move: If the base dries out and the code does not return on the next short run, the leak may have been a one-time event such as oversudsing or a spillover. If water reappears quickly or the code returns right away, you have an active leak or a stuck leak-sensing condition that needs closer inspection.
What to conclude: Water in the base pan is what usually triggers this code. The next job is finding what put it there.
LC and LE are often caused by foam or spray deflection, not a failed component. This is the fastest low-cost check.
Next move: If the dishwasher finishes cleanly with no new water in the base, the code was likely caused by suds or spray being redirected by the load. If the code returns with normal loading and no detergent mistake, move on to the door, spray arm, and filter area.
What to conclude: A dishwasher that only trips the code after certain loads usually has a splash or suds problem, not a major internal failure.
Front-corner leaks and splash leaks usually leave clues here. These are common, visible causes that homeowners can check without tearing deep into the machine.
Next move: If you find a clogged or loose filter area, a blocked spray arm, or obvious debris and the next test run stays dry, you likely solved it. If everything inside the tub looks sound but the code still returns, the leak is more likely from a hose, connection, or a worn sealing part.
When the code returns at the same point every time, the cycle timing tells you where to look next.
Next move: If you catch the first drip, you can usually narrow the repair to a gasket, spray arm, or hose issue instead of guessing. If you cannot see the source but the base keeps getting wet, the unit may need to be pulled for side and underside access.
By now you should know whether this was a soap/load issue, a visible wear item, or a leak hidden underneath the machine.
A good result: If two short cycles finish with a dry base and no code, the repair path was correct.
If not: If the code returns with a dry visible tub area and no obvious hose or gasket leak, the leak sensor circuit or a hidden internal leak needs professional diagnosis.
What to conclude: A repeat LC or LE after the easy checks usually means there is still water reaching the base pan, even if the source is small.

It usually means the dishwasher detected water in the base leak tray or thinks it has a leak. The cause can be a real drip, oversudsing, or water being sprayed out of place inside the machine.
Yes. Too much detergent, the wrong detergent, or extra rinse aid can create foam that pushes water into the base area and trips the leak sensor. That is one of the first things worth ruling out.
A small internal leak can drip into the base pan without reaching the kitchen floor. The leak sensor reacts to water underneath the tub, so you may get the code even when the outside looks dry.
Not until you know why it happened. If water is still reaching the base, each cycle can add more damage to flooring, cabinets, or electrical parts. Dry the base and confirm the source first.
There is not one part that fixes every LC or LE code. The most common homeowner-fix items are a dishwasher door gasket, dishwasher lower spray arm, or dishwasher drain hose, but only after you confirm the leak path.
No. Most of the time the sensor is doing its job and reporting water in the base. A bad sensor is much less common than suds, a door leak, or a small hose seep.
