Possible Causes

Root causes behind this error

• Clogged or kinked drain hose connected to sink drain or garbage disposal • Blocked dishwasher filter or spray arm holes due to food debris • Drain pump malfunction or failure • Water level float sensor stuck or defective • Clogged sink drain or garbage disposal preventing proper drainage • Air gap blockage (if your USA kitchen sink is equipped with one) • Faulty drain valve not opening completely • Wiring issues with the drain pump motor • Control board electronic malfunction • Improper installation of drain hose connections

Safety Checks You Can Do

Steps you can try at home safely

• Turn off the dishwasher circuit breaker for 60 seconds, then turn it back on to perform a full system reset • Verify the dishwasher door is fully closed and latched properly—ensure no obstruction prevents complete sealing • Check that the main water supply valve (located under your kitchen sink) is fully open • Inspect the drain hose for kinks, bends, or twists—straighten any crimped sections • Look for clogs where the drain hose connects to your sink drain or garbage disposal • Remove and clean the dishwasher filter basket located at the bottom of the tub—rinse away any food debris • Check that spray arm holes are clear by visually inspecting both upper and lower spray arms for blockages • If equipped, verify the sink air gap (small cylinder on countertop near faucet) is not clogged—rinse or clean if needed • Run your sink's garbage disposal to ensure the drain line is clear before running the dishwasher • Ensure you are using only high-quality automatic dishwasher detergent—avoid hand soap or low-sudsing products • Review your dishwasher's cycle settings and make sure a proper wash cycle (not a rinse-only cycle) is selected • Check that all spray arm components are properly installed and not loose or misaligned
