Samsung Dishwasher Leaking? Door, Underneath, or LC / LE Code — Spill Test, Supply Hose, Drain Hose, Door Seal, Dish Soap, Leveling, 22-Inch Opening, Nozzles — Fixes, Costs, Repair vs Replace (2026)
Quick answer
First, is it a leak or a spill? Samsung says wipe up the water and run a new cycle. If water doesn't come back, it wasn't a leak.
Samsung's free fixes, in its own order:
- Turn off power at the breaker. (If the leak is at the door, skip ahead to the door seal.)
- Water supply hose: look and feel for moisture, damage, or loose connections at both ends and along its length. Samsung recommends a 3/8-inch stainless steel hose.
- Drain hose: if it leaks where it connects to your home's drain, reinstall or tighten that connection.
- Door seal: if it's pushed out of its channel, push it back in, and clean it with a towel and mild soap.
- Dishwasher detergent only. Dish soap makes suds that escape and leak.
- Level it. If the front sits lower than the back, water pools at the door.
- Check the opening: over-tightened cabinet screws can stretch the tub sides. Samsung says the opening should measure exactly 22 inches where the screws are.
- Clean the nozzles and jets. Food in a nozzle can aim water at the door hard enough to push it past the seal.
LC or LE code, or a dishwasher that won't stop draining? The leak sensor found moisture. Power off, look for a leak, remove the garbage disposal cap if you just hooked one up, check for excess detergent, and give it time to dry. Still there? Samsung says request service, or call your installer if it's done this since day one.
Our partner pro call line is coming soon. Until then: if your appliance may still be under warranty, contact the manufacturer first. Otherwise, get two or three written quotes from local appliance repair companies, and ask about the diagnostic fee and the parts-and-labor warranty.
Verdict at a glance
| Your situation | What it usually means | Our verdict |
|---|---|---|
| It was a spill; suds from dish soap; seal out of its channel or dirty; not level; cabinet screws too tight; nozzles clogged; loose supply hose; disposal cap left in; sensor wet after a move | Detergent, loading, install, or moisture | ✅ Free fix (a new stainless supply hose is a cheap hardware-store part) |
| Seal damaged; drain hose leaking along its length; inlet valve dripping; LC / LE that returns after drying | Seal, drain hose, inlet valve, leak sensor | 🔧 Usually worth repairing (often Samsung service in year 1) |
| Water from under the tub that keeps returning; floor or cabinet already damaged; dishwasher 10+ years old with a second big repair in about 2 years | Pump, sump, tub, or repeat failures | ♻️ Lean toward replacing if the quote passes about half of a new dishwasher |
Safety check before any DIY (30 seconds)
Stop and don't start the DIY steps below if any of these is true:
- Active leak. Samsung's first step is to turn off power at the circuit breaker. If a supply leak is found, turn off the water supply too.
- LC / LE code. The dishwasher will turn itself on and keep draining until the moisture is gone, so Samsung says keep it unplugged or off at the breaker while you troubleshoot.
- Water near wiring or the junction box under the dishwasher. Breaker off before you touch anything.
- Soft floor, stained cabinets, or a musty smell: the leak may be old. Check for water damage and mold, and think about your home insurance.
- Removing the toe panel or pulling the dishwasher out means disconnecting water, drain, and power. If you aren't comfortable, call a pro.
- The dishwasher is in its first year (or an eligible extended period). Use Samsung's warranty service before removing panels.
- Recall check: search your model on the CPSC recall site before paying for a repair.
If none of these apply, the free checks below are safe for most owners.

Which Samsung dishwasher do you have?
Find the model and serial number on the label on the edge of the inner door or the side of the tub (open the door and look along the top or side edge). You need it to order the right seal, valve, or hose and to check warranty status.
| Type | Model prefix (examples) | Leak points to watch | Notes |
|---|---|---|---|
| Standard spray arm (StormWash, most current models) | Usually DW80 (check label) | Door seal, nozzles, supply and drain hoses | Leak codes show as LC or LE |
| WaterWall models | DW80 family (check label) | Door seal, reflector area | Samsung: make sure dishes don't block the water reflector |
| Models without a digital display | Varies (check label) | Same | Leak errors show as blinking light combinations; see your manual |
Prefixes are examples, not a full list. Use your own model number when you order parts.
Five-minute checks before you call anyone
- Spill test. Wipe up all the water and run a new cycle. Samsung says if water doesn't come back, it wasn't a leak.
- Watch where it starts with a flashlight: the door edge, under the door, the toe panel, and the cabinet under the sink.
- Suds? Read your detergent label. Samsung says if it doesn't say "dishwasher" (with the "-er"), it's not for dishwashers. Dish soap makes suds that escape.
- Door seal: run your finger along it. Push any loose section back into the channel. Wipe it with a towel and mild soap; even small debris can open a gap.
- Nozzles and jets: clear any stuck food. On WaterWall models, make sure nothing blocks the reflector.
- Supply hose (power off): look and feel at the dishwasher end, the shut-off valve end, and along the hose.
- Drain hose: check where it connects to your sink drain or disposal.
- Level: side to side (so the door doesn't bump the cabinets) and front to back (front lower than back pools water at the door).
- Opening width: measure across the opening exactly where the cabinet screws are. Samsung says it should be 22 inches. If it's wider, loosen the screws.
How to know it's fixed: a full cycle with a dry paper towel under the door and along the toe panel stays dry, and no LC / LE code returns.
Samsung's own pages split the blame for leaks
Samsung's support pages agree on the steps but send you to different people depending on the part and history. Here they are side by side.
1. A leak-sensor code (LC / LE) that won't clear: Samsung or your installer?
| Samsung: "Dishwasher is leaking or has a leakage error code" | Samsung: "Dishwasher will not turn off" | |
|---|---|---|
| What causes it | Moisture where it doesn't belong, even without a visible leak: a supply hose leak, a disposal cap left in, excess detergent, or water splashed near the sensor during a move | The leak sensor senses moisture and keeps draining: a leak, improper installation, leftover moisture from installation, or all of these |
| Who to call if it persists | After drying it out, if the error remains, request Samsung service | If it has done this since installation, it's an installation problem: go back to your installer. Only if it starts on a dishwasher that has worked for some time, request service |
2. Which leaks Samsung service covers.
| Part | What Samsung's leak page says |
|---|---|
| Water supply hose | Sold separately and not covered by service. Reinstall it or buy a new one (3/8-inch stainless steel recommended) |
| Drain hose at your home's drain | Part of the dishwasher, but a bad connection to the home isn't a dishwasher issue and isn't covered. Reinstall it |
| Drain hose anywhere else | Request service |
| Door seal | Push it back and clean it yourself. If it's damaged, request service |
Our take: start with the free steps either way. If the leak code started right after installation, call the installer first; it's their hookup. If it started later, or the seal is damaged, use Samsung service while the dishwasher is in warranty. Out of warranty, Samsung's seals and hoses are sold as parts (see the cost table), so a confident DIYer can replace them, but Samsung itself routes damaged seals to service.
Samsung dishwasher codes and signs linked to leaks
| Code or sign | Samsung's explanation | First fix (free) | If it continues | DIY tier |
|---|---|---|---|---|
| LC or LE (or blinking lights on models without a display) | The leak sensor detected moisture where it doesn't belong | Power off; look for leaks; disposal cap; excess detergent; let it dry; restore power | Request service (or the installer, if since install) | Easy → Pro only |
| Won't turn off; keeps draining | Usually the leak sensor sensing moisture | If you ran Sanitize, open the door or press Power; otherwise treat as LC / LE | Same as above | Easy |
| Suds at the door | Dish soap or dishwashing liquid used | Dishwasher detergent only | — | Easy |
| Water at the door | Seal out of its channel or dirty; not level; nozzles aiming water at the door; stretched tub sides | Reseat and clean the seal; level; clear nozzles; check the 22-inch opening | Damaged seal → service | Easy → Moderate |
| Water under or behind | Supply hose or drain hose connection | Reinstall or replace the supply hose; fix the drain connection | Drain hose elsewhere → service | Moderate |
Which part each symptom points at:
| Symptom | Part most often involved | DIY tier |
|---|---|---|
| Drips at the door after cleaning, leveling, and the 22-inch check | Door seal or tub gasket | Moderate |
| Drip at the dishwasher end of the supply line | Supply hose or inlet valve | Moderate |
| Tub fills too high or the valve drips while off | Water inlet valve (Samsung: below 20 psi can stop the valve shutting off) | Moderate |
| Wet drain hose along its length | Drain hose or clamp | Moderate |
| Puddle under the center during wash | Drain pump, sump, or internal hoses | Advanced |
| LC / LE with no water anywhere | Leak sensor or its wiring | Pro only |
Steps and codes from Samsung US Support pages (sources 1–5), checked 2026-10-30. The part mapping is our own from those pages and Samsung's part catalog. We cross-checked the LC code against the open ApplianceDB Samsung dishwasher sample (source 12), which lists LC as the leak sensor detecting moisture.
Diagnose by symptom → likely part
Before you touch parts: Switch off the breaker. Shut off the water supply valve. Lay towels down.
1. Leak at the door after the seal, level, and nozzle checks
Likely cause: a damaged door seal or tub gasket, or a door vent gasket on some models. Samsung says push a loose seal back into its channel and clean it; if it's damaged, request service.
DIY difficulty: Moderate.
| Part | What it does | DIY difficulty |
|---|---|---|
| Door seal / tub gasket | Seals the door to the tub | Moderate |
| Door vent gasket | Seals the vent in the door | Moderate |
2. Water under the front, from the supply side
Likely cause: the water supply hose (not a Samsung part), or the water inlet valve. Samsung says check both ends and the full length of the hose; reinstall it; if that fails, replace it, ideally with a 3/8-inch stainless steel hose. Samsung's water supply page adds that the 90-degree elbow needs a 1/2-inch NPT thread on one end and a 3/8-inch compression fitting on the other, and that pressure should be 20–120 psi. Below 20 psi, the supply valve may fail and not shut off properly.
DIY difficulty: Moderate.
| Part | What it does | DIY difficulty |
|---|---|---|
| Water supply hose (hardware store) | Carries water from your shut-off valve | Moderate |
| Water inlet valve | Lets water in; should close fully | Moderate |
3. Wet drain hose or water at the back during drain
Likely cause: the drain hose or its clamp. If it's the connection at your home's drain, reinstall it (Samsung says that's not covered by service). Anywhere else along the hose, Samsung says request service.
DIY difficulty: Moderate.
| Part | What it does | DIY difficulty |
|---|---|---|
| Drain hose | Carries water to the sink drain or disposal | Moderate |
| Drain hose clamp | Holds the hose on its fitting | Moderate |
4. Puddle under the center during the wash
Likely cause: something in the base: the drain pump, the sump, or an internal hose such as the sump-to-drain-pump hose. This is past Samsung's DIY steps; Samsung says request service.
DIY difficulty: Advanced.
| Part | What it does | DIY difficulty |
|---|---|---|
| Drain pump | Pumps water out | Advanced |
| Sump and motor assembly | Collects and circulates water | Advanced |
5. LC / LE code that comes back after drying
Likely cause: water still reaching the sensor from a hidden leak, or a fault in the leak sensor. Samsung's steps: power off, look for a visible leak (supply hose first), remove the disposal cap if you just hooked up a disposal, check for excess detergent (it stays moist longer than water), and give it time to dry. Restore power. If the error remains, request service.
DIY difficulty: Pro only (after the free steps).
| Part | What it does | DIY difficulty |
|---|---|---|
| Leak sensor | Detects water in the base | Pro only |
Call a pro if: water keeps coming from under the tub, the floor under the dishwasher is already wet, the code returns after drying, or the dishwasher is in warranty. If the problem started at installation, call the installer first.
Prevent it next time
- Use only dishwasher detergent, and don't overfill the dispenser or add detergent outside it (Samsung).
- Wipe the door seal with mild soap now and then.
- Keep nozzles and jets clear, and don't block the WaterWall reflector.
- Use a stainless steel supply line; Samsung says it's recommended for durability.
- Keep the shut-off valve easy to reach, shut it off if you'll be away a week or longer, and check the hose connection at the valve regularly (Samsung).
- Don't over-tighten cabinet screws after kitchen work.

What Samsung's warranty covers on a dishwasher
Per Samsung's US home-appliance warranty page:
| Period | What's covered | Who pays labor |
|---|---|---|
| Year 1 | Parts and labor (standard manufacturer's warranty) | Samsung |
| Limited-time | Free 2-year extended warranty on eligible dishwashers and other appliances bought July 9 to December 31, 2026 at participating retailers; claim form required, redeemed through SmartThings | Check your terms |
What this means for a leak: a damaged seal, leaking drain hose, or failed pump in year 1 is a warranty repair. But Samsung's warranty doesn't cover improper installation, and its leak page says the supply hose (sold separately) and the drain hose connection to your home aren't covered by service. Samsung also says frozen water or drain lines aren't covered. Keep your proof of purchase.
→ Samsung US: home-appliance warranty · Request service
Before you pay for any repair: a 4-point check
- Warranty: year 1; the free 2-year extended warranty if you bought during the July 9 to December 31, 2026 offer; retailer or credit-card extended protection; and your installer's workmanship guarantee if the leak started at install.
- Recalls: search your model at the U.S. Consumer Product Safety Commission's recall site: cpsc.gov/Recalls. A recall repair is free.
- Free fixes done: spill test, detergent, seal reseat and clean, nozzles, supply hose, drain connection, disposal cap, level, 22-inch opening, drying time for LC / LE.
- Written quote: ask for part, labor, and trip fee separately, and exactly where the leak was found.
What it costs: repair parts and pro service (2026)
How we price this table: DIY part prices are Samsung part numbers (DD-prefix) listed on Sears PartsDirect public search pages (S-list under Sources), USD before tax and shipping. Whirlpool, GE, LG, Frigidaire, and other non-Samsung part numbers in the same results were excluded, as were full door assemblies and outer panels. Ranges span several part numbers because the right part depends on your model number. Pro costs tagged [GUIDE] come from two US cost guides (Fixr = G1, HomeGuide = G2): national averages for dishwashers in general, not Samsung-specific quotes. "Varies — get a quote" means the searches didn't return that Samsung part, or the guides don't itemize the job, so we don't show a price.

Tip: tell the tech where the water shows up, when (fill, wash, drain, or while off), any LC / LE code, and whether the problem started at installation.
Repair vs. replace calculator
1. What's the all-in repair cost? → R = trip/diagnostic fee + part + labor + tax, minus anything Samsung's warranty (or a recall) covers
2. What does a comparable new dishwasher cost, all-in? → N = unit + delivery + installation + haul-away
3. How old is your dishwasher, and how long should it last? → Age and Life (use about 10 years, inside HomeGuide's 8–15-year range, if you don't know)
4. How much have you spent on repairs in the last 2 years? → Past
Step A — Cost ratio: R ÷ N
Step B — Life used: Age ÷ Life
Step C — Repeat-repair check: (R + Past) ÷ N
| Life used under 50% | Life used over 50% | |
|---|---|---|
| Repair under 50% of new | ✅ Repair | 🤔 Repair is usually fine. Check for other wear |
| Repair over 50% of new | 🤔 Get a second quote first | ❌ Replace |
Repeat-repair rule: if Step C is over 50%, lean toward replacing. If the part is no longer available for your model, replace.
Worked example 1 (illustrative numbers): A 2-year-old Samsung shows LE the week after it was pulled out for a kitchen floor job. Unplugged for a day to dry, it clears. R = $0.
→ Not a repair.
Worked example 2 (illustrative numbers): A 5-year-old Samsung drips at the door; the seal is torn. A tech replaces it: R = $150; N = $800.
150 ÷ 800 = 19%; life used 5 ÷ 10 = 50% → Repair.
Worked example 3 (illustrative numbers): A 10-year-old Samsung leaks under the center; the tech quotes a sump and motor assembly, a year after a drain pump ($250): R = $450; N = $800.
450 ÷ 800 = 56% (second-quote zone); life used 10 ÷ 10 = 100%; repeat check (450 + 250) ÷ 800 = 88% → Replace.
Tips toward replacing: a sump or pump leak on an older unit out of coverage, repeat LC / LE codes after repairs, or existing floor damage.
Tips toward repairing: it's a seal, supply hose, drain hose, or valve; the dishwasher is under about 7 years old; it's in warranty; or the installer owes you a fix.
Why 50%? It's the common rule of thumb, and the one we use. Some technician checklists draw the line a little higher, at about 60% of a new dishwasher's price, so treat a repair that costs 50–60% of new as a second-quote zone, not an automatic replace.
Who services Samsung dishwashers near you
1. Your installer (if it started at installation). Samsung says a dishwasher that has had a leak code or won't turn off since it was installed points to an installation problem the installer should fix.
2. Samsung (warranty or official service). In year 1 (or an eligible extended period), start with Samsung. Have your model, serial number, and proof of purchase ready.
→ Samsung US: request service
3. A partner appliance pro (out of warranty).
Our call line connects you with an independent appliance repair provider in your area. Tell them where the water appears and any LC / LE code.
Our partner pro call line is coming soon. Until then: if your appliance may still be under warranty, contact the manufacturer first. Otherwise, get two or three written quotes from local appliance repair companies, and ask about the diagnostic fee and the parts-and-labor warranty.
4. A plumber. For a leaking shut-off valve, low water pressure (under 20 psi), or a bad drain connection to the house.
5. DIY with the right part. A stainless supply hose, a seal reseat, and a drain hose connection are DIY-friendly. Order by your exact model number, and switch off the breaker and water first.
Questions to ask any technician:
- Where exactly did you find the leak (seal, valve, hose, pump, sump)?
- Did you measure the opening and check the dishwasher is level?
- Is this covered by Samsung, or is it an installation issue?
- Can you split the quote into part, labor, and trip fee?
- What warranty do you give on your labor?
Optional: is an appliance warranty worth it?
A home warranty (service contract) can cover repairs for a yearly fee plus a per-visit service fee. Read the exclusions carefully: many plans exclude plumbing problems, installation errors, and water damage to floors and cabinets. A dishwasher that's already leaking is usually not covered.
FAQ
Why is my Samsung dishwasher leaking from the bottom?
Samsung's checks, in order: make sure it's not a spill, then check the supply hose, the drain hose connection, the door seal, the detergent, the leveling, the 22-inch opening, and the nozzles. If it still leaks, request service.
What do LC and LE mean on a Samsung dishwasher?
The leak sensor detected moisture where it doesn't belong, even if you can't see a leak. Samsung says power it off, look for a leak, remove the disposal cap on a new hookup, check for excess detergent, and let it dry. If the code returns, request service.
Why won't my Samsung dishwasher turn off?
Usually the leak sensor: it senses moisture and keeps trying to drain. If you ran Sanitize, the display stays on until you open the door, which is normal. If it's done this since installation, Samsung says call your installer.
Is the water supply hose covered by Samsung?
No. Samsung says the supply hose is sold separately and not covered by service. It recommends a 3/8-inch stainless steel hose from a hardware store.
Can a dishwasher be installed too tight?
Yes. Samsung says over-tightened cabinet screws can stretch the tub sides and cause leaks. The opening should measure exactly 22 inches where the screws are.
Can I replace a Samsung dishwasher door seal myself?
Samsung's own advice is to reseat and clean the seal, and request service if it's damaged. Out of warranty, Samsung seals are sold as parts, so replacing one is a moderate DIY job if you order by model number.
Is it worth fixing a leaking Samsung dishwasher?
Usually yes if it's a seal, hose, or valve. A sump or pump leak on a dishwasher older than about 10 years, especially after another recent repair, usually isn't. Use the calculator above.
