KitchenAid Dishwasher Error Code F6E3 — Suds or Air in Water Pump
What this means
Error code F6E3 indicates that excessive suds or air bubbles are present in the dishwasher's water pump. This is most commonly caused by using the wrong type of detergent (such as dish soap instead of dishwasher detergent), using too much detergent, or a water fill issue that allows air into the pump system. The suds or air prevent the pump from operating efficiently.
Alternate codes: F6 E3, 6-3
Step-by-step fix
4 stepsCancel the current cycle
Press Cancel/Drain to stop the current cycle. Let the dishwasher drain any remaining water.
Wait 2-3 minutes for the drain cycle to complete fully.
Remove excess suds
Open the door carefully and use towels to soak up any visible suds from the tub. Remove the lower rack to access the bottom.
Pour 1 cup of white vinegar into the bottom of the tub to help break down remaining suds.
Run a rinse cycle
Close the door and run a Rinse Only cycle to flush out remaining suds and air from the pump system.
You may need to run 2-3 rinse cycles to fully clear stubborn suds.
Use correct detergent going forward
Ensure you are using only dishwasher-specific detergent (not hand dish soap). Use the amount recommended on the detergent packaging.
Using too much detergent is a common cause — most cycles need only 1 tablespoon of detergent for normal loads.
When to call a professional
This error is almost always user-correctable. Call a professional only if the error persists after clearing suds and running multiple rinse cycles, which may indicate a water inlet valve or pump issue.
