KitchenAid Dishwasher Error Code Flood Switch Activated LED

This LED indicates the dishwasher's flood detection switch has tripped because water was detected outside the normal wash circuit. The unit shuts down automatically to prevent water damage. Possible causes include a leaking lid seal, faulty water valve, cracked spray arm, damaged hoses, heater plate o-ring failure, or moisture reaching the chassis board. The dishwasher will not operate again until the source of the leak is found and resolved.

No, you should not operate the dishwasher while this LED is active. The flood switch is a safety feature that indicates water is present in an area it should not reach, which can cause water damage to cabinetry and flooring or create a risk of moisture contacting electrical components. Unplug the unit until the source of the leak has been identified and repaired.

Repair costs vary depending on which component is responsible for the water leak. Parts such as a replacement lid gasket, inlet hose, or spray arm typically range from $10 to $60, while a water inlet valve or heater plate o-ring may cost $20 to $80 in parts. If professional labor is needed, total repair costs including diagnostics and parts can range from $100 to $300 or more depending on the complexity of the repair and local service rates.

Start by unplugging the dishwasher, then remove the lid and inspect the lid seal and motor assembly for damage or improper fit. Check all hoses for splits or blockages, inspect the spray arms for cracks and free rotation, and examine the heater plate o-ring for wear. Repair or replace any faulty components before restoring power, and also confirm that dishware is loaded correctly so it does not block the lid from sealing or obstruct the spray arms.

Simply resetting or power cycling the dishwasher will not permanently clear this error if the underlying problem has not been fixed. The flood switch will re-activate as soon as the same leak or moisture condition occurs again. The LED will only stop appearing once the root cause, such as a faulty seal, hose, or spray arm, has been corrected.
