LG dishwashers
LG dishwashers report faults in a compact two-letter dialect that LG documents openly: IE for fill, OE for drain, AE for leaks, HE and tE for the heating side. The codes are direct-drive-era honest - each names a subsystem, and each has an official first step before anyone opens the machine.
A photo of the model label and the complete installation helps the team understand the configuration before the visit.
Front-control machines with the four-arm QuadWash spray system and inverter direct-drive motor.
Top-control models adding TrueSteam and Dynamic Dry on the upper trims.
The STUDIO dishwashers with height-adjustable third rack and premium finishes.
LG's brushless wash motor - the platform's quiet, long-warranty heart.
Start with the symptom
A symptom narrows the inspection; it does not identify the failed component. The $99 visit confirms the actual fault on the exact model before any repair is authorized.
Heater, vent and rinse-aid dosing - the condensation-dry reality, tested in order.
The OE path: filter, sump, pump, hose - plus the air-gap check.
IE territory - valve, line, fill valve.
San Diego hard water versus detergent and rinse settings - adjusted before parts.
Latch and hinge tension on top-control doors - a mechanical fix.
The TrueSteam generator and its water path have their own service points.
Series and model numbers
One code dialect across the line - what changes by model is the hardware behind it: steam generators and third racks join the map on upper trims.
Model label
The model and serial label is on the right side edge of the door panel, visible when the door is open. Photograph it with the code showing on the display. Photograph the complete label — the full model and serial identify parts and production year better than the series name alone.
Indicators and alerts
For any message not shown, use the manual for the exact model rather than a generic list.
LG diagnostics
IE, OE, AE/E1, HE and tE meanings are verified against LG USA's official support library. Codes whose meanings vary by generation are handled per model rather than flattened into one blog-style table.
Preventive service and owner care
Alpha Pro provides preventive and general maintenance for LG dishwashers. The appliance design determines which procedures are accessible and appropriate.
Owner maintenance
Professional maintenance
A professional visit can evaluate accessible systems without assuming every procedure applies to every model.
Diagnosis before parts
Call or book with the model label, exact behavior, any displayed codes, photos, and access notes.
The technician examines the reported condition in context: fill, wash, drain, drying, controls, leaks, and relevant components.
Findings and proposed work are explained before repair proceeds. The residential diagnostic is credited toward an approved repair.
Service areas and operating context
Alpha Pro serves LG dishwashers in communities including La Jolla, Del Mar, Rancho Santa Fe, Carmel Valley, Poway, and the full San Diego County footprint below — ZIP by ZIP. Installation and room conditions vary from the coast to inland homes.
Recurring condensation, marine exposure, ventilation limits, and visible corrosion can be useful details during repair or maintenance.
Share room conditions, recent heat events, ventilation restrictions, and when the symptom appears.
During maintenance, accessible metal surfaces can be inspected for corrosion, moisture exposure, or conditions that may warrant attention. Location alone does not establish the cause of a failure.
A better repair decision
There is no honest universal age or price threshold. Start with the exact model and a diagnosis.
Local notes · San Diego County
LG's built-in dishwashers come in front-control and top-control styles and share a recognizable platform: QuadWash multi-motion spray arms, TrueSteam, Dynamic Dry, an inverter direct-drive wash motor and, on many models, a vario motor that routes water between arms. When something goes wrong, the display says a lot, from AE leak alerts to nE vario faults. This page decodes LG's published code list, explains how water from different utilities across the county affects the machine, and sets out which repairs are worth paying for.
More than 20 retail water agencies buy from the San Diego County Water Authority, and nearly all of the tap water they deliver is hard or very hard. The 2025 reports show City of San Diego plants at 237 to 243 mg/L, Helix Water District at 206 mg/L, Otay at 9.4 grains per gallon, Sweetwater at 193 mg/L and Cal Am in Coronado at 236 mg/L. For 2024, Santa Fe Irrigation District reported 275 mg/L and Poway 236 mg/L. The practical range at the tap is roughly 9 to 16 grains. For an LG dishwasher, the harder the supply, the faster scale reaches the heater (HE), the inlet valve (IE) and the spray arms (which can contribute to AE). Climate plays a smaller role than it does for refrigerators, but it still counts. Damp marine-layer months on the coast encourage gasket mildew in machines kept closed. Grid stress during heat waves, such as SDG&E's record demand in September 2024, can interrupt a cycle, and LG uses PF to flag a power failure. For city detail, see our Chula Vista, La Jolla and Poway LG dishwasher pages.
Symptom: AE/E1: leak float up. FE: too much water. bE: suds. Cause: Base-pan water from an unlevel unit, dirty gasket, damaged spray arms or a leak; hand soap for bE; overfill for FE. Fix: Level, clean the gasket, use dishwasher detergent only; for suds LG suggests 4 to 7 oz of milk on the upper rack and an AUTO cycle. We fix leak sources and test the inlet valve for FE.
Symptom: IE means the fill level wasn't reached in 10 minutes; OE means the tub won't drain. Cause: IE: closed valve, pressure outside 20 to 120 psi, drain hose below 10 inches, unlevel unit, clogged inlet valve. OE: kinked or blocked hose, blocked disposal inlet, clogged filter, failed pump. Fix: Correct valve, pressure and hose height; clean the filter and clear the disposal inlet. We replace a restricted inlet valve or a worn drain pump.
Symptom: LE or CE is a wash motor error; nE is a vario motor error. Expect noise or no wash action. Cause: A wash motor or harness fault for LE and CE; a failed vario (water-guide) motor for nE. Fix: LG's first step is breaker off for 10 seconds, then restart. If the code returns, we test the motor and harness and replace the wash motor or the vario motor.
Symptom: HE is a heater error; tE is a thermal error. Dishes come out cool and wet or the cycle halts. Cause: A heater or thermistor fault, a heater that isn't heating, or water above 149°F (HE) or 194°F (tE). Fix: Power-cycle once. Persistent codes get heater, thermistor and board testing, and we replace whichever part fails.
LG's help library emphasizes a few installation and use points that prevent many codes: use only dishwasher detergent at the correct dose, keep the machine level, and route the drain hose so it doesn't sit below 10 inches and siphon. Supply pressure should fall between 20 and 120 psi. Clean the filter monthly as a baseline. Then adjust for your utility: a home on roughly 9-grain water can descale less often than one near 16 grains, and anyone seeing white film on glassware should shorten the interval.
From high-rise condos on the coast to large inland family homes, the visit follows the same order. We start with the code and the cycle stage where it appeared, then check the supply valve, drain hose and disposal connection under the sink. Next come the filter and sump, then the components the code points to: float switch, drain pump, inlet valve, heater or motors. Help us prepare by sending the model and serial number, the code and any building access rules when you book, and clear the sink cabinet before arrival.
Sort the likely repair by tier. Low: filter and hose problems, suds, leveling and many leak repairs. Low to medium: drain pumps and inlet valves. Medium: heaters, thermistors, the vario motor and wash-motor diagnosis. Most of these are worth doing on a dishwasher in otherwise good condition. The expensive scenario is a failed main wash motor together with a control board on an older machine, where replacement may be the better spend.
Helpful answers
Clear preparation makes a service request easier to evaluate.
Yes - same-day windows are offered across San Diego County subject to the day's schedule. Availability is confirmed for the exact address when you book.
Yes. It is non-refundable and credited toward the total repair cost if you proceed. There are no residential exceptions.
A 90-day labor warranty and a 1-year parts warranty, both starting on the date the repair is completed.
No. A symptom narrows the search, but the diagnostic visit on the exact model confirms the actual fault before any repair is authorized.
A drain error - officially, most often food debris in the filter or an installation issue. Clean the filter first; a persisting OE means pump or drain-path service.
A leak inside the machine has tripped the base float switch. Close the water supply and book - the code stays until the leak is found and fixed.
On the right side edge of the door panel, visible when the door is open.
Codes like AE report a physical condition - water in the base pan - not a software state. The condition has to be repaired, then the code clears.
Yes - the STUDIO machines share the code dialect and inverter drive with the LDT line, with their own trim-level parts.
None of them is a parts failure by itself. PF indicates a power failure interrupted the cycle. CL means the child lock is on, which is a setting rather than an error. CR indicates test mode. Clear the lock or restart the cycle; if PF appears often without any outage, have the power supply and board checked.
For motor codes, LG suggests turning off the breaker for 10 seconds and restarting, which can clear a one-time glitch. If a code returns after a reset, the fault is still there. Avoid repeated resets on leak codes; find out why water reached the base pan first.
IE can also come from water pressure outside 20 to 120 psi, a drain hose installed below 10 inches that siphons water out, an unlevel machine or a scale-clogged inlet valve. The valve under the sink may also be only partly open after other plumbing work.
We serve homes throughout San Diego County, from the coastal cities to the inland valleys, Monday through Saturday, 7 a.m. to 6 p.m. Our Chula Vista, La Jolla and Poway pages describe local water and housing conditions in more detail.
