LG Dishwasher Error Codes IE, OE, FE, LE, HE, AE — What They Mean & How We Fix Them

LG dishwashers (LDF, LDT, LDP, LDP series with QuadWash and TrueSteam) display fault codes on the front panel. The Twin Cities calls we see most are OE (drain restriction — usually a kitchen-side disposal knockout left in place), IE (inlet valve / supply hose), and AE (AquaStop leak in the base pan).

What we fix in Minneapolis

The Minneapolis repair mix

OE — drain code (the #1 LG dishwasher call)

OE means the dishwasher tried to drain and the water didn't leave the sump in the expected time. In Twin Cities homes the cause is almost always one of three things, in order: (1) disposal knockout plug still in place from a new disposal install — the dishwasher physically can't drain. (2) Clogged sump filter — pull the cylindrical filter on the tub floor and rinse. (3) Drain hose kinked or clogged. The drain pump itself is the fourth cause. Free fix in ~40% of OE calls.

IE — inlet code

Check the supply valve under the sink is open (gets bumped closed), then check the inlet screen at the back of the dishwasher for sediment. Twin Cities hard water (~17 gpg in Minneapolis) silts the inlet screen over time. If supply and screen are fine, it's the inlet valve solenoid — $225–$285 all-in.

AE / E1 — leak detected, AquaStop tripped

Water hit the base pan and lifted the AquaStop float. Most common leak paths: the door gasket (especially the bottom corner), the sump-to-tub gasket, and the supply-hose AquaStop connector at the back. We tip the unit, dry, dye-test, replace the leaking part. $245–$385 all-in. Don't reset and re-run without finding the leak.

From the truck

Field-service notes on dishwasher repair

On dishwasher repair, we keep the diagnostic tight because the failure catalog on this brand is well-documented. Minneapolis water hardness runs 8–15 grains per gallon depending on your source, which chews through steam-generator elements, valve seats, and dishwasher heating elements faster than the spec sheet assumes.

Because this page focuses on oe — drain code (the #1 lg dishwasher call), our tech opens the call by isolating that subsystem before touching anything else. Wear parts (belts, pumps, igniters, valves) ship from our truck stock; boards and sealed-system parts are OEM-only from Marcone or the manufacturer's direct distributor. The $149 residential diagnostic is credited toward the repair if you approve; if you don't, you pay only the diagnostic and we leave a written scope. Every completed repair carries a 1-year parts and labor warranty in writing. The section above covers the specific failure surface — oe means the dishwasher tried to drain and the water didn't leave the sump in the expected time.

We stock the top-30 wear items for this brand on the truck, so most first-visit repairs close same-day. We're EPA 608 certified for sealed-system and refrigerant work, licensed and insured in Minnesota, and every tech carries a factory diagnostic laptop for brand-specific service modes. If the model is out of parts support, we'll say so on the first call and refund the diagnostic — that's the honest read on a repair-vs-replace decision, and it's the same read we'd give a family member calling about the same dishwasher.

FAQ

Minneapolis questions, answered

  • What does OE mean on an LG dishwasher?

    OE = drain fault. Check first: disposal knockout plug still in place (very common on new disposal installs), clogged sump filter, kinked drain hose. Drain pump is the fourth cause. ~40% of OE calls are a free fix at the disposal.

  • What does IE mean on an LG dishwasher?

    IE = water inlet fault. Confirm the supply valve under the sink is open, then check the inlet screen at the back of the dishwasher for hard-water sediment. If supply and screen are fine, it's the inlet valve solenoid — $225–$285.

  • What does AE mean on an LG dishwasher?

    AE = AquaStop leak detector tripped — water hit the base pan and locked the inlet. The fix is to find and seal the leak (door gasket, sump gasket, or AquaStop hose), not just reset. $245–$385.

  • What does FE mean on an LG dishwasher?

    FE = overfill. The inlet valve stuck open and the dishwasher is filling past the level switch. Turn off the supply valve under the sink immediately and call us — the inlet valve needs replacement before you run it again. $225–$285.

  • How much does LG dishwasher repair cost?

    Most LG dishwasher repairs land $245–$465 all-in. Drain pump $245–$365. Inlet valve $225–$285. AquaStop / leak repair $245–$385. Wash motor $345–$525. Control board $325–$465. The $149 trip fee is waived when you approve the repair.
