KitchenAid Dishwasher F6E3 Error Code
Too many suds on KitchenAid dishwashers.
KitchenAidAll KitchenAid dishwasher codes
Sensors picked up foam in the bottom of the tub, and the dishwasher may refuse to fill until it's gone. The usual causes are the wrong soap (hand dish soap, laundry detergent), too much dishwasher detergent, or a rinse aid cap left off.

How to fix KitchenAid F6E3
Scoop out the foam
Look in the tub bottom. Use a plastic cup to bail out as much foam as you can, and take the dishes out.
Knock down the rest with cooking oil
Pour 2 to 3 tablespoons of vegetable oil into the tub floor. It flattens the remaining suds.
Run two empty cycles
Run one full cycle with no detergent and no dishes, then a second with detergent in the cup. Check the rinse aid cap is screwed down before you start.
When to call a technician
If you get F6E3 with the right detergent and no visible foam, a sensor may be misreading and a technician should look at it.
