Error codeF6E3
ApplianceDishwasher
Excessive suds are what F6E3 reports on a Whirlpool built-in dishwasher. With foam detected, the dishwasher may not operate properly or may not fill with water.
Where the foam comes from
Laundry detergent, hand soap or hand dish detergent in the dishwasher
A rinse aid cap that was not put back after filling
Too much dishwasher detergent
Getting rid of suds
Use a plastic cup to scoop out the suds.
Remove the dishes.
Pour 2-3 tablespoons of vegetable cooking oil into the dishwasher to suppress the suds.
Run one full cycle with no detergent and no dishes.
Run a second full cycle with the detergent cups filled, still with no dishes.
Upkeep
The manual suggests cleaning the dishwasher approximately every 30 days.
