Samsung Dishwasher LC Error Code: Leak Sensor Triggered

Quick Answer

The Samsung LC error code means the leak sensor in the base pan detected moisture. Samsung's base pan sensor is more sensitive than most competitors and frequently triggers from condensation after hot cycles, not a real leak. Before tilting the machine, unplug for 30 minutes to let condensation dry.

In my fifteen years of fixing Samsung units, the LC code is often a ghost. It usually triggers because the dishwasher is slightly unlevel or you ran a heavy Sanitize cycle that created too much steam. This moisture drips into a shallow tray and hits a very sensitive sensor. If your floor is dry, you likely don't have a plumbing disaster, just a moisture management issue that needs a specific drying sequence.

What Does the LC Code Mean?

When I walk into a kitchen with an LC code, the first thing I do is check the bottom corners of the door. If those are dry, we're looking at a nuisance trip caused by over-sudsing or heavy steam. It's a protective shutdown designed to save your hardwood floors, but Samsung definitely tuned this sensor to be a bit too jumpy for its own good.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Condensation from Sanitize or high-heat cycle dripping into base pan (false positive)40%

Door gasket leaking at bottom corners24%

Cracked or loose sump hose connection14%

Leak sensor itself failed or water-logged12%

Tub stress crack near sump10%

Symptoms You May Notice

LC code on the display and the cycle stops mid-wash or won't start at all
You just ran Sanitize, Steam, or any high-heat cycle and the code showed up right after it finished
Floor under the dishwasher is completely dry but the error just won't go away
Code keeps coming back every few weeks like clockwork, usually after hot cycles
When you tilt the unit forward, a noticeable amount of water runs out onto the towels underneath

Can you reset a Samsung dishwasher to clear the LC code?

You cannot reset this by pressing buttons. The sensor is physically wet and must dry out to clear the logic board. I recommend unplugging the unit and tilting it forward about 45 degrees to let the trapped water spill onto a towel. Once the tray is dry, the code clears itself on power-up. If it comes right back, you have a genuine leak.

Frequently Asked Questions

Why does my Samsung dishwasher show LC with no water on the floor?

It's common for the sensor to trip from just a few tablespoons of water. Samsung uses a shallow plastic tray under the tub to catch drips. On a humid day or during a steam-heavy cycle, condensation can roll down the inner cabinet and pool right on the sensor. In these cases there's no leak on your kitchen floor because the tray is actually doing its job, but the dishwasher stays locked out until that tray is bone dry.

How do I drain the base pan to clear the LC code?

First, unplug the unit to avoid any shorts. Pull the dishwasher out from the cabinets just enough to get a solid grip on both sides. Place thick towels in front of the machine and tilt the whole unit forward toward you at about a 45 degree angle. Hold it there until the dripping stops. This empties the base tray. Let it sit upright and unplugged for about 30 minutes before plugging it back in. You want the sensor surface completely dry, not just the tray mostly empty.

Will the LC code clear on its own?

Technically yes, if the water evaporates the code will clear. But here's the thing: if there's a real puddle in the base pan, it could take days to dry out naturally because there's basically zero airflow under there. The tilt method is the only way to get back to washing dishes the same day. If the code comes right back after you reset it, you've got a mechanical leak that needs a part replaced. Don't just keep tilting it and hoping it'll stop.

My Samsung keeps getting LC every few weeks. What's wrong?

If this is happening every few weeks, you've probably got a slow leak somewhere. Check for over-sudsing first. Using too much detergent creates foam that escapes the tub and hits the sensor. If you're using pods and the floor is level, check that door gasket for small tears. Even a tiny gap lets a few drops out every cycle, and those drops eventually fill the tray enough to trigger the sensor again. Also check the sump hose clamp. I replaced three of those on Samsung units in a two week stretch last fall, it's more common than people think.

How much does it cost to fix an LC error on a Samsung dishwasher?

Depends on the cause. If it's just condensation, it costs you nothing except 30 minutes of your time. Door gasket DD61-00603B is $20-35 for the part and you can do it yourself in about 20 minutes. A sump hose is usually under $15. The leak sensor DD81-01399A itself runs about $20-30 if the sensor has failed and needs replacing. If you've got a cracked tub, that's basically a total loss since the repair would cost more than a new machine. A tech visit to diagnose and fix a hose or gasket is usually $150-250 all in depending on your area.
