Lg ldp6797bd dishwasher error code ae not draining properly — used dishwasher normally then experienced flooding

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   Stop the dishwasher. From a dry, safe location, close the dishwasher water supply valve and switch off its power at an accessible dry disconnect or circuit control. If water is near the electrical connection, the floor is wet, or there is smoke, a spark, a burning smell or damaged wiring, do not touch the unit or wet connector; keep people away and have qualified electrical or appliance help make the area safe.

   Expected result: The surrounding floor and electrical access are dry and intact, or there is standing water, a wet connection, smoke, a spark, an electrical odor or visible damage.

   Next step: Leave the dishwasher isolated. For any water or electrical hazard, arrange qualified service and, if household wiring or plumbing is involved, the appropriate electrician or plumber.

   Stop if: Do not reach behind the dishwasher, unplug it in a wet area, reset power, or restore the water supply to see whether the code clears.

   Why this matters

   Why: AE is a leakage/protection event, and the manual directs the owner to turn off the water supply and obtain service. A wet or damaged installation is a shock, fire or property-damage hazard rather than a drain-filter problem.

2. Check 2

   Before anyone clears the display, photograph and transcribe the exact message and timing: AE versus OE, FE or another character, whether it was flashing or beeping, and whether it appeared during fill, wash, drain, drying or after the cycle ended. Record the full model from the rating label as LDP6797BD and the serial number without moving the built-in unit.

   Expected result: The display is confirmed as AE, it is actually OE or FE, the code is unclear, or the message reappears after power is isolated.

   Next step: Give the code photo, exact model/serial and cycle stage to LG service. If the message is not clearly AE, use only the exact manual for that confirmed code and do not borrow a generic button sequence.

   Stop if: Do not enter service mode, clear stored faults, or reconnect the dishwasher just to obtain a cleaner code recording.

   Why this matters

   Why: LG's manual assigns different decisions to AE leakage, OE drainage and FE excess water. A code that is misread as not-draining can send the owner toward a filter or pump check while an internal leak remains active.

3. Check 3

   With water and power isolated, inspect only what is visible without pulling the dishwasher: the floor in front of it, the lower door edge, adjacent cabinet, sink base, disposal or air-gap area, and the visible supply or drain connection if already exposed. Note the water's location, amount, color or detergent foam; do not remove panels, hoses, the float or the lower cover.

   Expected result: Water is centered at the dishwasher door/base, appears under the sink or drain connection, is accompanied by detergent foam, or no source is visible and AE remains recorded.

   Next step: Photograph the safe visible evidence and keep the appliance isolated. Ask service to inspect the installed leak path; ask a plumber to address a sink, disposal, air-gap or household drain source when that is where water is observed.

   Stop if: Do not pull the built-in dishwasher forward, tilt it to drain the base, dismantle the door or float assembly, or run a test cycle.

   Why this matters

   Why: A door, hose, water valve, foam or external plumbing issue can produce water, but the location alone cannot prove a component failure. No visible floor water does not rule out an internal leak or a triggered protection system.

4. Check 4

   Separate the flood event from the code history in writing: note whether the dishwasher had been operating normally before the event, whether water arrived during fill or drain, whether the sink or disposal was being used, whether excess suds or a leveling/door-alignment issue was present, and whether AE returned without another cycle. Do not try to reproduce any of these conditions.

   Expected result: The flood followed filling, followed draining or sink use, occurred with visible suds, was present with the dishwasher off, or the trigger cannot be determined.

   Next step: Provide the sequence and photographs to LG service and any plumber involved. Keep the water supply and power off until the leak source and installation are inspected.

   Stop if: Do not substitute OE drainage instructions for AE, force the pump, add chemicals, or repeatedly cycle power and water.

   Why this matters

   Why: The sequence helps a technician distinguish an appliance leak, excessive-water/oversudsing condition, drain or external plumbing overflow, and a continuing inlet issue. It does not identify a valve, pump, seal, float or control board for replacement.

5. Check 5

   Prepare the service handoff without opening the appliance: include the LDP6797BD model and serial, purchase and installation information, AE photo, water location, cycle stage, whether the breaker or GFCI operated, whether the sink or drain was in use, and whether anyone already reset or moved the unit. Keep the dishwasher out of service while waiting.

   Expected result: The unit is still under the original installation or warranty arrangement, the installation identity is incomplete, or the event involved a breaker/GFCI trip or repeated AE.

   Next step: Request qualified LG dishwasher service and give the electrician or plumber the same event record when their domain is implicated. Preserve the installation and avoid unauthorized repairs until the service decision is made.

   Stop if: Do not authorize a pump, valve, float, seal or control replacement from AE alone, and do not continue operating while water or power safety is uncertain.

   Why this matters

   Why: The exact model, installation context and event history determine which service path owns the next inspection. A recurring AE or any electrical/water hazard needs professional diagnosis, not a consumer part decision.
