Possible Causes

Root causes behind this error

• Drainage hose kinked, bent, or pinched behind or under the dishwasher • Clogged or blocked drain filter due to food particles or debris • Dishwasher drain hose disconnected from sink drain or garbage disposal • Sink drain or house drain line is blocked or clogged • Drain pump impeller jammed with foreign objects • Faulty drain pump motor or pump assembly failure • Water inlet valve malfunction preventing proper water level regulation • Control board electrical fault detecting false drainage error • High-loop drain hose configuration issue (drain line higher than dishwasher outlet)

Safety Checks You Can Do

Steps you can try at home safely

• Turn off the circuit breaker supplying power to your dishwasher for 60 seconds, then turn it back on to reset the control board • Ensure the dishwasher door is fully closed and latched properly, as improper closure can trigger sensor errors • Check that the water supply shutoff valve under your sink is fully open (turn counterclockwise) • Inspect the drain hose behind and underneath the dishwasher for kinks, bends, or pinches that restrict water flow • Verify the drain hose is properly connected to your sink drain or garbage disposal outlet • Remove and clean the dishwasher filter basket (typically located at the bottom of the tub) by rinsing away food debris and buildup • Flush your sink drain with hot water to ensure your home's drain line is not blocked • Confirm you are using proper dishwasher detergent and the correct cycle setting for your load • Check the control panel settings to ensure you have not selected a delayed start or special cycle mode • Do not attempt to disassemble the pump, drain motor, or internal drainage components as this may void your warranty and create safety hazards
