LG Dishwasher Leaking? AE / E1 Code, Door, Underneath — Level, Detergent, Door Gasket, Spray Arms, 90° Elbow, Supply Line, Inlet Valve, Drain Hose, Sump — Fixes, Costs, Repair vs Replace (2026)
Quick answer
LG says most dishwasher leaks come from installation, detergent, or maintenance, not a broken part. LG's help library lists these fixes, cheapest first:
- Level the dishwasher. LG says if it isn't level, about a gallon of water can pour to one side and out the door.
- Detergent. Use one pod, or fill the dispenser only to the 15 or 25 line. Never use hand dishwashing liquid; its suds push water out.
- Door gasket. Wipe off food and buildup. A torn gasket needs service.
- Spray arms. Make sure they spin freely and nothing tall blocks them or sprays water at the door.
- Underneath: the 90° elbow and supply line. LG's paper-towel test: wipe the elbow and the supply line with a dry paper towel and see which one gets wet. LG suggests Teflon tape on the elbow threads, hand-tightening and then snugging with a wrench, and replacing a stripped elbow (they're sold at home improvement stores).
AE or E1 on the display? LG says that's a leak that tripped the float switch in the base. Fix the cause above, then dry the base pan: breaker off, remove the two kick-plate screws, dry the pan, leave the kick plate off 24–48 hours, switch the breaker off and on to reset, and run an empty cycle. If AE / E1 comes back with one pod and a level unit, LG says a technician is needed.
Still leaking? LG says to request service. LG Canada notes that water on the floor while the dishwasher isn't running points to the inlet line, and that a unit that floods while idle may need an inlet valve.

Verdict at a glance
| Your situation | What it usually means | Our verdict |
|---|---|---|
| Dishwasher not level; dish soap or too much detergent; food on the gasket; a tall item blocking a spray arm; drip at the 90° elbow; AE / E1 right after one of these | Installation, detergent, or maintenance | ✅ Free fix. Level, one pod, clean, tape and tighten, dry the base |
| Gasket torn; leak from the supply line or inlet valve; water on the floor when it isn't running; wet drain hose or sump area | Door seal, inlet valve, drain hose, sump parts | 🔧 Usually worth repairing |
| AE / E1 keeps returning with one pod and a level unit; leak under the tub you can't trace; floor or cabinet already damaged; dishwasher 10+ years old with a second big repair in about 2 years | Pump, 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 or flooding. Turn off the water supply under the sink (LG) and switch off the dishwasher's breaker. Don't run it again until you've found the source.
- Water near wiring or the junction box under the dishwasher. Breaker off before you touch anything. LG's AE / E1 drying steps start with the breaker off.
- Soft floor, stained cabinets, or a musty smell: the leak may be old. Check for water damage and mold, and consider your home insurance.
- Taking off the kick plate or pulling the dishwasher out means working near water, drain, and power. If you aren't comfortable, call a pro.
- The dishwasher is in its first year (two years on some LG models). Use LG's warranty service before you remove panels.
- Recall check: search your model on the CPSC recall site before paying for a repair (see "Recalls" below).
If none of these apply, the free checks below are safe for most owners.

Which LG dishwasher do you have?
Find the model and serial number on the label along the side edge of the inner door or tub opening. You need it to order the right seal, valve, or hose, and to check your warranty.
| Type | Model prefix (examples) | Common leak points | Notes |
|---|---|---|---|
| Front-control | Often LDF / LDFN / LDFC (check label) | Door gasket, under the door, supply elbow | AE / E1 leak code on most |
| Top-control | Often LDT / LDTS / LDTH / LDP (check label) | Door top and corners, under the door | Same code and base pan |
| Any model | — | 90° elbow, supply line, inlet valve, drain hose | Under the sink and behind the kick plate |
Prefixes are examples, not a full list. Your owner's manual shows your model's leveling feet and kick-plate screws.
Five-minute checks before you call anyone
- Dry everything, then run a short cycle and watch with a flashlight: the door edges, the bottom of the door, the kick plate, and the cabinet under the sink.
- Check the water level. LG's leak video says to look at the water level after the initial fill. If it looks too high, the dishwasher may be tilted, or the inlet valve may not be closing.
- Detergent: one pod, or the dispenser filled only to the 15 or 25 line. If someone used hand dish soap, run an empty rinse and wipe out the suds before the next load.
- Gasket: run a finger around it and wipe off food and residue. Look for tears (LG says a torn seal needs service).
- Spray arms: spin each by hand. Move tall pans or cutting boards so they don't block an arm or deflect spray onto the door.
- Level: check side to side and front to back. LG's video shows the leveling feet are reached with the door open about 45–60° and the lower cover removed.
- Paper-towel test under the sink and at the kick plate: wipe the 90° elbow, then the supply line, with a dry paper towel. Whichever gets wet is the leak.
- Water on the floor while it's off? LG Canada says that points to the inlet line. Shut off the water and call for service if it floods while idle.
How to know it's fixed: a full cycle with a dry paper towel under the door and at the elbow stays dry, and no AE / E1 appears.
What LG says vs. what LG says (and an outside code list)
LG's own pages don't agree on how much of this is DIY, and an open code dataset reads E1 differently:
| LG USA help library: "Troubleshooting Leaking Issues" | LG USA: "AE & E1 Error Code" | LG Canada: "Water leaking underneath" | Non-OEM: ApplianceDB open dataset | |
|---|---|---|---|---|
| A leak at the supply connection | DIY: dry paper-towel test; Teflon tape on the elbow; hand-tighten, then firmly with a wrench; replace a stripped elbow from a home improvement store | Not covered | If water appears when the dishwasher isn't running, suspect the inlet line; if it floods while idle, shut off the water and LG will dispatch a technician (possibly an inlet valve) | — |
| What AE / E1 means | — | A leak that activated the float switch in the base | — | E1 = flow switch |
| When to call | If the leak continues after these steps, request service | If AE / E1 shows when using one pod, a technician is needed | Flooding while idle | — |
Our take: the elbow fix is fair game for most owners: water off, Teflon tape, hand-tight plus a snug turn. A leak from the supply line or valve itself, or water on the floor while the dishwasher is off, is a pro job, as LG Canada says. For the code, trust LG's meaning (leak / float switch) over the outside dataset; LG's float sits in the base pan, and drying the pan is LG's own reset step.
LG dishwasher codes and signs linked to leaks
| Code or sign | LG's explanation | First fix (free) | If it continues | DIY tier |
|---|---|---|---|---|
| AE or E1 | A leak activated the float switch in the base | Level, gasket, spray arms, one pod; then dry the base pan (breaker off, 2 kick-plate screws, 24–48 hours, breaker reset, empty cycle) | Technician if it returns with one pod | Moderate → Pro |
| Water from the door | Unit tilted; door top or corners distorted; spray hitting the door | Level; check the upper rack and door edges | Door seal, service for a bent door | Easy → Pro |
| Suds at the door | Wrong or too much detergent | One pod; never dish soap | — | Easy |
| Wet elbow or supply line | Loose, untaped, or stripped elbow; supply line | Teflon tape, tighten, replace the elbow | Supply line, inlet valve | Moderate |
| Floor wet while not running | Inlet line (LG Canada) | Shut off the water | Inlet valve service | Pro only |
Which part each symptom points at:
| Symptom | Part most often involved | DIY tier |
|---|---|---|
| Leak at the door edge after cleaning and leveling | Door seal (or tub gasket) | Moderate |
| Wet elbow even after tape and tightening | Elbow fitting (hardware) or supply line | Moderate |
| Tub overfills, or floor is wet while the dishwasher is off | Water inlet valve | Moderate → Advanced |
| Wet drain hose or a drip at the back during drain | Drain hose or its connector | Moderate |
| AE / E1 returns with one pod and a level unit | Sump, sump gasket, check valve, a hose inside the base, or a pump | Advanced |
| Float stuck, or AE / E1 with a dry base | Float assembly | Advanced |
Steps from LG USA Support (sources 1–3) and LG Canada (source 4, labeled), checked 2026-10-30. The part mapping is our own from those pages and LG's part catalog on Sears PartsDirect. The ApplianceDB dataset (source 9) is a non-OEM cross-check; where it differs from LG, we follow LG.
Diagnose by symptom → likely part
Before you touch parts: Switch off the breaker. Turn off the water supply under the sink. Lay towels down.
1. Leak at the door edge or corners after cleaning and leveling
Likely cause: a torn or worn door seal or tub gasket. LG's video also lists distortion at the top or corners of the door, which is a service job, not a seal swap.
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. Tub overfills, or water appears when the dishwasher is off
Likely cause: the water inlet valve isn't closing fully, or the supply line is leaking. LG Canada says a leak while the dishwasher isn't running points to the inlet line, and that flooding while idle may need an inlet valve.
DIY difficulty: Moderate → Advanced.
| Part | What it does | DIY difficulty |
|---|---|---|
| Water inlet valve | Lets water in; should close fully | Moderate → Advanced |
3. Wet drain hose, or water at the back during drain
Likely cause: a cracked drain hose or a loose hose connector. LG's video lists the inlet and outlet hose connections among leak points.
DIY difficulty: Moderate.
| Part | What it does | DIY difficulty |
|---|---|---|
| Drain hose / connector | Carries wastewater to the sink drain or disposer | Moderate |
4. AE / E1 keeps coming back with one pod and a level unit
Likely cause: a leak inside the base: the sump gasket, a check valve, an internal hose, or a drain or circulation pump. LG says a technician is needed at this point.
DIY difficulty: Advanced.
| Part | What it does | DIY difficulty |
|---|---|---|
| Sump gasket / sump parts | Seal the bottom of the tub to the pump area | Advanced |
| Drain pump / circulation pump | Pump water out, or around the tub | Advanced |
AE / E1 that won't stay gone? A technician can trace the leak inside the base in one visit.

Recalls
We searched for LG dishwasher recalls on 2026-10-30. Some third-party repair blogs describe a recent LG dishwasher recall for a fire hazard (not a leak). We couldn't confirm it on cpsc.gov this session: CPSC's site search didn't return an LG dishwasher recall, and CPSC's dishwasher recall list blocked our fetch. So we don't repeat any model list here. Search your exact model at cpsc.gov/Recalls or with LG before paying for a repair. Recall repairs are free.
Prevent it next time
- One pod per load, or fill only to the 15 or 25 line. Never hand dishwashing liquid.
- Wipe the door gasket and keep tall items from blocking the spray arms.
- Keep it level, especially after a floor is redone or the dishwasher is moved.
- Check under the sink every few months with a dry paper towel at the elbow and supply line.
- Know where your water shutoff is, so a leak doesn't become a flood.

What LG's warranty covers on a dishwasher
LG's US dishwasher warranty cards (they vary by model; your card or LG's site has yours):
| Period (from original retail purchase) | What's covered | Who pays labor |
|---|---|---|
| Year 1 (some models 2 years) | Parts and labor on defective parts | LG |
| Up to 5 years | Main control board and racks (parts only) | You |
| Up to 10 years | Direct Drive motor (parts only) | You |
| Limited lifetime | Stainless steel tub and door liner (parts only) | You |
What this means for a leak: a defective door seal, inlet valve, hose, or pump in year 1 (or year 2 on 2-year models) is a warranty repair. After that, a leaking stainless tub or door liner may still be covered as a part, so you'd pay labor only: check before you pay. Detergent problems, a dishwasher that isn't level, and a loose or untaped elbow are installation or use issues, not defects. Water damage to floors and cabinets isn't something the appliance warranty pays for. Keep your proof of purchase.
→ Check your model's warranty on LG's site · Schedule an LG repair · LG customer service 1-800-243-0000
Before you pay for any repair: a 4-point check
- Warranty: year 1 (or 2) parts and labor; lifetime tub and door liner parts; retailer or credit-card extended protection.
- Recalls: search your model at cpsc.gov/Recalls.
- Free fixes done: level, one pod, gasket, spray arms, elbow tape, base pan dried.
- 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 LG-format part numbers listed on Sears PartsDirect public search pages for "lg dishwasher …" searches (S-list under Sources), USD before tax and shipping. Most listings aren't brand-labeled, so confirm the fit with your model number. Whirlpool, GE, Samsung, Frigidaire, Bosch, and other brands' parts, freezer gaskets, and unrelated sensors in the same results were excluded. Ranges span several part numbers because the right part depends on your model. Pro costs tagged [GUIDE] come from two US cost guides (Fixr = G1, HomeGuide = G2): national averages for dishwashers in general unless marked, not LG-specific quotes. "Varies — get a quote" means neither guide itemizes that repair, so we don't show a number.

Tip: tell the tech where the water shows up (door, under the door, or under the sink), when (fill, wash, drain, or while off), and whether AE / E1 appeared. That points straight at the seal, valve, hose, or base.
Repair vs. replace calculator
1. What's the all-in repair cost? → R = trip/diagnostic fee + part + labor + tax, minus anything LG'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): An LG dishwasher shows AE after a new floor raised the back. You level it, dry the base pan for 48 hours, and reset the breaker. R = $0.
→ Not a repair.
Worked example 2 (illustrative numbers): A 4-year-old LG drips under the sink. The paper towel shows the elbow is fine but the supply line is wet, and the tub overfills. A tech replaces the inlet valve: R = $190; N = $850.
190 ÷ 850 = 22%; life used 4 ÷ 10 = 40% → Repair.
Worked example 3 (illustrative numbers): A 10-year-old LG keeps throwing AE with one pod. The tech finds a leaking sump and quotes the sump and a circulation pump, a year after a drain pump ($250): R = $460; N = $850.
460 ÷ 850 = 54% (inside the 50–60% second-quote zone); life used 10 ÷ 10 = 100%; repeat check (460 + 250) ÷ 850 = 84% → Replace.
Tips toward replacing: a leak inside the base on an older unit, repeat AE / E1 after repairs, or existing floor damage.
Tips toward repairing: it's a seal, hose, elbow, or valve; the dishwasher is under about 7 years old; or the part is covered.
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.

Questions to ask any technician:
- Where exactly did you find the leak?
- Did you check the inlet valve for overfill and the elbow for a stripped thread?
- Is the tub or door liner covered as a part under LG's warranty?
- 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: plans usually exclude water damage to floors and cabinets, and problems from installation.
FAQ
Why is my LG dishwasher leaking from the bottom of the door?
LG's top causes: the dishwasher isn't level, too much or the wrong detergent, buildup on the door gasket, or a blocked spray arm sending water at the door.
What does AE or E1 mean on an LG dishwasher?
LG says it's a leak that activated the float switch in the base. Fix the cause, then dry the base pan with the breaker off and the kick plate removed for 24–48 hours.
How do I reset an LG dishwasher after an AE error?
LG says switch the breaker off and back on after drying the base pan, then run an empty cycle. If AE returns with one pod and a level unit, a technician is needed.
Why is my LG dishwasher leaking underneath?
Start with the 90° elbow and the supply line: wipe each with a dry paper towel. LG suggests Teflon tape and a snug wrench turn on the elbow, or a new elbow if it's stripped.
Why is there water under my LG dishwasher when it's not running?
LG Canada says that points to the inlet line. If it floods while idle, shut off the water; it may need an inlet valve.
Can I use dish soap in an LG dishwasher?
No. LG says never use hand dishwashing liquid; it makes suds that leak out. Use one pod, or fill to the 15 or 25 line.
How much does it cost to fix a leaking LG dishwasher?
Often nothing. When we checked Sears PartsDirect on 2026-10-30, LG-format door seals and tub gaskets were listed at about $43 to $86 and inlet valves at about $63 to $132. Fixr says a leaking dishwasher costs about $200 to fix on average.
Should I replace a leaking LG dishwasher?
Rarely for a seal, elbow, hose, or valve. Consider it for a leak inside the base on an older unit, or AE that keeps returning after repairs.
