GE Dishwasher Leaking? Door, Underneath, or Air Gap — Suds, Rinse Aid, Door Gasket, Corner Baffles, Vent Cap, Hose Clamps, Inlet Valve, LEAK DETECTED / 999 — Fixes, Costs, Repair vs Replace (2026)

Verdict at a glance

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 a "LEAK DETECTED" alert with beeping. GE says to disconnect power to the dishwasher until it can be repaired. Switch off the breaker and shut the water supply valve under the sink.
• Water near wiring or the junction box under the dishwasher. Breaker off before you touch anything.
• Standing water: mop it up with towels or a wet/dry vacuum. Don't let water sit in the cabinet base or under the floor.
• 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. Use GE's warranty service before removing panels (see the warranty section).
• Recall check: search your model on the CPSC recall site before paying for a repair. GE has had past dishwasher recalls (for fire hazards, not leaks), so it's worth the minute.

If none of these apply, the free checks below are safe for most owners.

Fix order at a glance (cheapest first)

DIY tiers: Easy (no tools) · Moderate (basic tools, toe panel off, or the dishwasher slid forward) · Advanced (dishwasher pulled out, pump area) · Pro only (tub, wiring, leak sensor, or under warranty).

Which GE dishwasher do you have?

GE's owner's manual says the model number is on the left tub wall, visible with the door open. You need it for the right gasket, baffle, valve, or hose, and to tell which gasket style you have.

Two gasket styles, two checks (per GE):

• Black gasket mounted on the tub: easy to inspect by eye. These models don't have corner baffles.
• Light gray gasket mounted on the door: it wraps around the bottom of the door, so check it by eye and by touch along the bottom. The ends don't meet at the bottom by design; a gap of about three inches is normal. These models have black corner baffles in the front lower corners of the tub.

Prefixes are examples, not a full list. Use your own model number when you order parts.

Five-minute checks before you call anyone

1. Dry everything, then run a short cycle and watch with a flashlight: door edges, under the door, the toe panel, the sink air gap, and the cabinet under the sink.
2. Open the door mid-cycle. Suds or foam? Stop the cycle. GE says suds can take several hours to settle, so let them dissipate before you run it again. Then switch to automatic-dishwasher detergent only.
3. Rinse aid: look at the dispenser. Wipe up any spilled liquid rinse aid. If you have a water softener and still get suds, GE suggests leaving out rinse aid.
4. Gasket: look for tears, cuts, or wear, and run your finger along the bottom on light gray gasket models. Remember the three-inch gap is normal.
5. Corner baffles: on light gray gasket models, look for the two black pieces in the front lower corners of the tub.
6. Door contact: close the door slowly. Does the control panel or door edge touch the counter or a cabinet? If so, the door may latch without sealing.
7. Vent cap: on the inside of the door at the top corner, hand-tighten it.
8. Spray arms: clear any blocked holes and look for splits in the arms. Water from a blocked or split arm can be thrown at the door.
9. Air gap and sink: if water comes out of the chrome air gap cap next to the faucet, the drain path is blocked (sink, disposer, or the air gap itself).
10. Under the sink (power off): look for drips at the supply valve, the inlet hose, and the drain hose clamps.

How to know it's fixed: a full cycle with a dry paper towel under the door and along the toe panel stays dry.

GE's own pages disagree on two leak questions

GE Appliances publishes several leak articles, and they don't always give the same answer. Here they are side by side.

1. What does "999" on the display mean?

Our take: check your exact model number against GE's list on the 999 page. If your model is on the list and there's no water under the dishwasher, the reset is a free first step. If your model has Floor Protect with Alert, or you see LEAK DETECTED or water, treat it as a leak: power off and book service.

2. Can you fix a leak under the dishwasher yourself?

Our take: both are right for different spots. A loose clamp under the sink, where you can see it, is a fair DIY job. Water coming from under the tub itself, or a LEAK DETECTED alert, is a service call. Don't pull the dishwasher out to hunt for it unless you're comfortable disconnecting water, drain, and power.

GE dishwasher codes and signs linked to leaks

Which part each symptom points at:

Codes and steps from GE Appliances' US support articles (sources 1–8) and the GE Appliances Factory Service FAQ (source 9), checked 2026-10-30. The part mapping is our own from those pages and GE's part catalog. We cross-checked the C1, C4, and 999 meanings against the open ApplianceDB GE dishwasher sample (source 14), which matches GE's listing.

Diagnose by symptom → likely part

1. Leak at the door edges after the suds and door-contact checks

Likely cause: a torn, cut, or worn door gasket (or the black tub gasket on tub-mounted models).

GE says a new dishwasher needs several complete wash cycles to seat its new gasket, so a small drip in the first week isn't always a defect. On an older dishwasher, inspect the whole gasket. GE says to remove the old gasket and seat the new one in its grooves; when it's right, it spreads evenly on both sides. It may take several tries.

DIY difficulty: Moderate.

2. Leak at the lower front corners (light gray gasket models)

Likely cause: missing or damaged corner baffles. GE says to check the front inside lower corners of the tub for the black pieces, one on each side. If either is missing or damaged, buy the part. Models with a black tub-mounted gasket don't have them.

DIY difficulty: Moderate.

3. Leak at the top corner of the door

Likely cause: a loose vent cap. GE says hand-tighten it. If it's tight and still drips, the door vent gasket may be worn. Warm, moist air from an external vent during drying is normal and not a leak.

DIY difficulty: Easy → Moderate.

4. Tub overfills, C4 code, or the inlet drips when the dishwasher is off

Likely cause: a stuck float, a failed float switch, or a sticking water inlet valve. For C4, GE says to touch Start and then Cancel/Reset, tap the float cover (the upside-down cup in the front left corner of the tub floor) to free it, and clear the rear sump. A valve that drips with the dishwasher off is usually the valve itself or its connection.

DIY difficulty: Moderate → Advanced.

5. Wet drain hose, or water under the sink during drain

Likely cause: a loose hose clamp or a cracked drain hose. GE's factory-service FAQ says tighten loose clamps with a flat-head screwdriver. A hose that's split or brittle needs replacing with the right part for your model.

DIY difficulty: Moderate.

6. Puddle under the front center, or LEAK DETECTED that keeps coming back

Likely cause: something inside the base: the drain pump, a pump seal, or a pump-to-sump hose. GE says leaking from underneath, or a LEAK DETECTED message, needs service. On Floor Protect models, the pan catches up to 19 ounces and tilts forward for bigger leaks so you can see the water at the front.

DIY difficulty: Advanced → Pro only.

Call a pro if: water comes from under the tub, the floor is already wet under the dishwasher, the leak sensor keeps tripping, or the dishwasher is in year 1. On models covered by GE's lifetime tub and door liner term, a liner that won't hold water is a GE repair.

Prevent it next time

• Use only automatic-dishwasher detergent. Never hand dish soap.
• Rinse off dish-soap residue if you pre-wash dishes by hand (GE).
• Don't wash sponges or dish cloths in the dishwasher (GE).
• Fill the rinse aid dispenser carefully and wipe spills.
• Keep the sink drain and air gap clear; run the disposer before you start the dishwasher.
• Make sure the door doesn't touch the counter or cabinets after any kitchen work.
• Check the inlet and drain hoses and the door gasket now and then (GE).
• Keep the spray arm holes clear.

What GE's warranty covers on a dishwasher

Per the GE dishwasher limited warranty printed in GE dishwasher owner's manual 49-55076 (see Sources); terms vary by model and year, so check your own manual:

What this means for a leak: in year 1, a failed gasket, valve, pump, or hose is covered. On models with the lifetime liner term, a tub or door liner that leaks is covered for life. GE doesn't cover improper installation, delivery, or maintenance (a door that hits the cabinet, or a loose hookup, can count here), cleaning or servicing of the air gap, resetting breakers or replacing fuses, commercial use, or damage from accident, fire, or floods. Keep proof of the original purchase date.

→ GE Appliances service: GEAppliances.com/service · 800.GE.CARES (800.432.2737) (from the GE manual)

Before you pay for any repair: a 4-point check

1. Warranty: year 1; any lifetime tub or door liner term on your model; retailer or credit-card extended protection.
2. Recalls: search your model at the U.S. Consumer Product Safety Commission's recall site: cpsc.gov/Recalls. A recall repair is free.
3. Free fixes done: suds, rinse aid, door contact, gasket check, corner baffles, vent cap, spray arms, air gap, hose clamps, 999 reset (listed models only).
4. 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)

Part prices checked 2026-10-30 on Sears PartsDirect public search pages (S1–S8). Pro-cost cells tagged [GUIDE] from G1 (Fixr) and G2 (HomeGuide), re-read 2026-10-30; [GUIDE] figures are national averages, not GE-specific quotes. Prices change; confirm with your model number.

Tip: tell the tech where the water shows up (door edge, lower corners, under the front, or under the sink), when (fill, wash, or drain), and whether you saw LEAK DETECTED or 999.

Repair vs. replace calculator

1. What's the all-in repair cost? → R = trip/diagnostic fee + part + labor + tax, minus anything GE'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

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 3-year-old GE dishwasher pushes foam onto the floor the week someone filled the rinse aid and spilled it. You wipe the spill, let the suds settle for a few hours, and run it again. R = $0.
→ Not a repair.

Worked example 2 (illustrative numbers): A 6-year-old GE drips at both lower front corners; one corner baffle is cracked and the other is missing. You buy both baffles and fit them: R = $50; N = $800.
50 ÷ 800 = 6%; life used 6 ÷ 10 = 60% → Repair.

Worked example 3 (illustrative numbers): An 11-year-old GE shows LEAK DETECTED; the tech finds a leaking pump and a worn sump hose, a year after an inlet valve ($180): R = $380; N = $800.
380 ÷ 800 = 48%; life used 11 ÷ 10 = over 100%; repeat check (380 + 180) ÷ 800 = 70% → Replace.

Tips toward replacing: a pump or tub leak on an older unit out of coverage, repeat leaks, or existing floor damage.
Tips toward repairing: it's a gasket, baffle, vent cap, hose, clamp, valve, or float; the dishwasher is under about 7 years old; or it's covered (year 1, or the lifetime liner term).

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 GE dishwashers near you

1. GE Appliances (warranty or official service). In year 1, or for a leaking tub or door liner on models with the lifetime term, start with GE. GE's support pages route repair appointments through its service partner (Bodewell), and the manual lists 800.GE.CARES (800.432.2737). Have your model number (left tub wall), serial number, and proof of purchase ready.

2. A partner appliance pro (out of warranty, or water under the tub).
Our call line connects you with an independent appliance repair provider in your area. Tell them where the water appears and whether you saw LEAK DETECTED or 999.

3. A plumber. If water backs up out of the air gap or the sink drain is clogged, it's a plumbing job, and GE's warranty excludes air gap cleaning.

4. DIY with the right part. Gaskets, corner baffles, vent gaskets, and hose clamps 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 (door, baffle, pump, hose, valve)?
• Is my model covered by GE's lifetime tub or door liner term?
• Did you check that the door doesn't hit the cabinet and that the dishwasher is level?
• 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 GE dishwasher leaking from the bottom of the door?
GE's usual suspects are suds from the wrong detergent or spilled rinse aid, a door that hits the counter or cabinet, a torn or worn gasket, missing corner baffles on light gray gasket models, a loose vent cap, and blocked or split spray arms. Check them in that order.

Is the gap in my GE dishwasher door gasket normal?
On models with a light gray gasket mounted on the door, yes. GE says the ends don't meet at the bottom by design, and a gap of about three inches is normal.

What does LEAK DETECTED mean on a GE dishwasher?
On models with Floor Protect with Alert, a moisture sensor in the pan under the dishwasher found water. GE says the dishwasher cancels the cycle and pumps out. If it's beeping, disconnect power. GE says service is needed.

What does 999 mean on a GE dishwasher?
It depends on the model. On Floor Protect with Alert models, it's a possible leak, so call service. On models listed on GE's 999 page, hold Cycle Select and Start for 5 seconds, then press any button to reset the control.

My new GE dishwasher leaks a little. Is it broken?
Not necessarily. GE says a new dishwasher needs several complete cycles to seat its door gasket. Also make sure the control panel edge isn't hitting a cabinet.

Why is water coming out of the air gap by my sink?
GE says backed-up water comes out of the air gap when the sink drain or disposer is clogged, or the air gap itself needs cleaning. Clear the sink and clean the air gap. GE's warranty doesn't cover air gap cleaning.

Can rinse aid make my GE dishwasher leak?
Spilled liquid rinse aid can cause suds that push water out. Wipe up spills. If you have a water softener and still get suds, GE suggests leaving out rinse aid.

Is it worth fixing a leaking GE dishwasher?
Usually yes if it's a gasket, baffle, vent cap, hose, or valve. A pump or tub leak on a dishwasher older than about 10 years, especially after another recent repair, usually isn't. Use the calculator above.
