Code
Meaning
Severity
Page
E1
The dishwasher is detecting a water filling problem or a siphoning condition. This can mean water is not entering the tub correctly, or water is draining out as fast as it fills in due to incorrect drain hose routing.
medium severity
E4
The dishwasher has detected a water supply fault or an activated float switch. The drain sequence has been initiated and the machine is prevented from operating until the condition is resolved.
medium severity
E15
The dishwasher's leak detection system has detected moisture in the base of the appliance. The machine has shut down as a precaution. This code indicates an actual water leak, not a sensor false alarm, and must be investigated before the machine is used again.
high severity
F1E1
Water has been detected in the base (drip tray) of the dishwasher. The machine has initiated a drain sequence and locked itself out of further operation to protect the motor and electronics. This is a safety shutdown, not a soft error.
high severity
F6E1
The dishwasher has encountered a condition that prevents new cycles from starting. A cycle already in progress will run to completion, but the machine will not accept a new cycle start command until the fault is cleared.
medium severity
F6E3
The dishwasher has detected too much foam or suds in the tub. The cycle has paused to allow the suds to dissipate. This is typically caused by using the wrong type of detergent.
low severity
F6E4
The dishwasher's overfill protection float has been triggered, either because the machine is not level and water is pooling to one side, or because the float switch itself is stuck or obstructed.
medium severity
F8E4
The dishwasher's drip tray (base pan) sensor has detected water in the bottom of the cabinet. This indicates a slow or active internal leak. The machine has stopped to prevent further overflow.
medium severity
F8E5
The dishwasher has detected a water leak and has triggered a full protective shutdown. The machine will not operate again until the leak source is repaired. This is a critical safety code — the water supply must be turned off immediately.
high severity
F9E1
The dishwasher is unable to drain water from the tub within the expected time. This is one of the most common dishwasher faults and is usually caused by a blockage in the drain path rather than a component failure.
medium severity
F9E2
The dishwasher is draining, but not at the expected rate or volume. Water may remain in the bottom of the tub after a cycle. This differs from F9E1 in that the drain pump is functioning but the flow is restricted.
medium severity
FAE5
The dishwasher completed a cycle but ended with an error condition. The control board has detected an issue that prevented the cycle from completing normally. Also displayed as F10E5 on some models.
medium severity
H2O
The dishwasher has paused the current cycle because it cannot confirm adequate water supply. The display shows H2O to indicate a water-related hold. The cycle will resume once the water supply issue is resolved.
medium severity
