Samsung dishwashers incorporate multiple sensor systems to ensure optimal wash performance: water level sensors, temperature probes, turbidity sensors (that measure water clarity to determine cleaning progress), flow meters, and leak detection systems in the base pan. Error codes appear on the display panel when these sensors detect conditions outside normal operating parameters, providing a starting point for diagnosis.
Based on service data, the most frequent Samsung dishwasher error codes relate to: drainage failures (clogged filters, blocked drain pumps, kinked drain hoses — accounting for roughly 35% of all service calls), water supply issues (inlet valve failure, low water pressure, fill timeout — 20%), heating element failures (element burnout, thermal fuse trips — 15%), door latch and seal problems (switch failure, misalignment — 12%), and leak detection activation (spray arm seal degradation, door gasket wear, hose connection loosening — 10%).
Many Samsung dishwasher errors are preventable with regular maintenance: clean the filter assembly monthly (most common cause of drainage errors), run a hot cleaning cycle with dishwasher cleaner quarterly (prevents buildup that triggers turbidity sensor errors), inspect the spray arms for debris blocking the nozzles (causes poor wash performance leading to extended cycles and heating errors), check the door gasket for food particle buildup (prevents leaks that trigger flood protection), and verify the drain hose connection at the disposal or drain pipe (prevents backflow errors).
