LG Dishwasher Not Cleaning

This page applies when a LG dishwasher is not cleaning. The symptom describes an outcome, not a component diagnosis. Two machines can show the same result for different reasons, so preserve the program, display message, timing, load and water observations. Do not order a pump, valve, heater, latch, board or sensor from the symptom alone. Controls and access differ by model; the rating plate and model manual remain the authority for model-specific actions. Start with the operating context. Confirm what program was selected, whether it reached a normal end state and whether the display reported an alert. For not cleaning, the most useful evidence is soil pattern, loading position and spray-arm clearance. A single observation narrows the support conversation without pretending to identify an internal failure. Check the accessible conditions identified in LG's official dishwasher guidance: loading, spray-arm movement, filters and detergent use. Keep each observation separate. Correct only a visible loading, filter, control or connection issue that the model instructions permit; do not remove panels, bypass a latch or energize exposed parts. Run at most one normal confirmation cycle after a safe, documented correction. Use the same load and program where practical and note whether the symptom changes. Repeatedly restarting a leaking, electrically abnormal or non-draining appliance can enlarge damage and is not a diagnostic substitute.
