Signs

What you may observe

• Water pooling at the bottom of the dishwasher tub after a cycle completes • Dishwasher stops mid-cycle and displays F8-E2 on the control panel • Gurgling or unusual sounds coming from the drain area • Dishes and interior remain wet after the cycle finishes • Error code persists even after attempting to restart the cycle • Foul odors emanating from the dishwasher drainage area

Possible Causes

Root causes behind this error

• Clogged or kinked drain hose restricting water flow • Debris, food particles, or mineral buildup blocking the internal drain pump • Faulty drain pump motor unable to operate properly • Blocked air gap (if installed under the sink) preventing proper drainage • Drain filter filled with food particles and detergent residue • Malfunctioning drain valve preventing water expulsion • Dishwasher not properly leveled, causing water to pool rather than drain • Issues with the standpipe or kitchen sink drain line accepting water backup • Control board sensor malfunction detecting false drainage obstruction

Safety Checks You Can Do

Steps you can try at home safely

• Turn off power to the dishwasher at the circuit breaker for 60 seconds, then turn back on to reset the control system • Verify the dishwasher door is fully closed and the latch mechanism is engaged • Check that the water supply valve under the sink (if applicable) is fully open • Inspect the drain hose behind and under the dishwasher for kinks, bends, or crushing • Ensure the drain hose is not installed above the sink rim level, which can prevent proper drainage • Remove and clean the dishwasher's filter basket located at the bottom of the tub, rinsing away all food debris • Check the drain opening inside the dishwasher for visible blockages or food particles and remove manually if safe • Verify that your kitchen sink drain is not clogged by running water and checking for backup • Confirm you are using appropriate low-suds dishwasher detergent designed for automatic dishwashers • Check control panel settings to ensure the proper wash cycle is selected and no child lock is activated • Inspect the air gap (small cylindrical device on the sink counter or mounted under the sink) for clogs if your installation includes one • Ensure the dishwasher is level using a spirit level; adjust feet if tilting forward or to the sides
