Lg d1452wf dishwasher overfilling slow draining — occurs about once a week resolves itself after a few days · fe

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

1. Check 1

   Photograph the display and record the complete model as D1452WF, when FE appears (during fill, wash, drain, or at the end), whether the tub is above its normal water level, and whether the drain pump runs automatically. Note whether the display is FE rather than OE, EI, or another code.

   Expected result: FE appears during or after filling with excess water and automatic draining, or the code/timing is unclear or is actually OE/EI.

   Next step: Use the FE branch only when the display and timing match. If the code is not clearly FE, stop guessing and use the exact manual entry for the displayed code.

   Stop if: Do not reset repeatedly or start another cycle while water is above the normal level, the code is unclear, or the pump is running continuously.

   Why this matters

   Why: The exact D1452WF manual ties FE to excessive water above the normal level and separates it from OE's water-not-pumped-away path and EI's leak path. A misread code would send the diagnosis to the wrong branch.

2. Check 2

   If FE is accompanied by ongoing filling, water on the floor, a wet hose connection, or an overfilled tub, stop the dishwasher. From a dry, safe position close the dishwasher water tap and disconnect power using the accessible plug or switch; do not pull out a built-in unit or reach into the water.

   Expected result: The water supply stops and no further water enters, or water continues, the tap is inaccessible, or a leak remains visible.

   Next step: Keep the tap closed and the appliance isolated, then request qualified service. Report whether the pump continued to drain and where water was seen; do not reconnect the machine just to see whether FE returns.

   Stop if: Do not remove the inlet valve, disconnect a pressurized hose, tilt the dishwasher, or open the base, pump, wiring, or control housing.

   Why this matters

   Why: LG's FE guidance treats excess water and leakage protection as a floor and appliance safety issue, and the D1452WF manual identifies the inlet valve as one possible FE cause. Stopping water and power limits further filling but does not prove the valve is the failed part.

3. Check 3

   Only after the tub has cooled, the water tap is safely closed if needed, and there is no active leak, inspect the accessible filter and visible drain hose for food residue, a kink, or a crushed section. Do not remove the pump cover or reach into standing water.

   Expected result: The filter is visibly clogged or the hose is kinked, or the accessible drain path looks clear while water remains or draining stays slow.

   Next step: When safe and permitted by the manual, clear only the accessible filter or restore gentle hose routing, then stop. If water remains, the code returns, or the pump sounds abnormal, arrange service rather than treating the drain check as an FE repair.

   Stop if: Do not work in hot water, dismantle the pump, use tools inside the drain opening, or run repeated tests with standing water.

   Why this matters

   Why: The D1452WF manual lists a clogged filter and kinked drain hose under OE, not as the definition of FE. A visible drain restriction can explain slow pump-out after an overfill, but a clear path shifts the problem toward a pump or control issue that needs service.

4. Check 4

   For the weekly or self-recovering pattern, keep a short incident record: date, cycle, FE timing, water level, automatic-drain duration, slow-drain observation, detergent used, and whether the appliance was left isolated. Do not deliberately reproduce the event with a loaded cycle.

   Expected result: FE returns under a similar fill condition, appears only with a particular detergent or load, or does not recur while the appliance remains isolated.

   Next step: Give the record, model, serial number, display photo, and water/slow-drain observations to qualified service. Do not order an inlet valve or water-level component without model-specific testing.

   Stop if: Stop immediately for smoke, burning odor, exposed wiring, repeated breaker operation, uncontrolled filling, water near electrical parts, or any need to open the appliance.

   Why this matters

   Why: Repeated FE under a fill condition supports a recurring water-control or inlet path problem; a detergent-related pattern may indicate oversudsing, which LG lists as one possible FE/AE trigger. A quiet interval while isolated does not establish that the valve, sensor, or control has recovered.
