Kenmore Dishwasher Error Code F6E3

The F6E3 error code on a Kenmore dishwasher indicates that the control has detected suds or air in the pump system. During normal operation, the pump relies on consistent water contact to maintain prime and move water effectively through the wash circuit. When excessive suds or trapped air enter the pump, the unit loses hydraulic efficiency, causing the control board to flag this fault. The code can also trigger when the diverter disk, which directs water between the upper and lower spray arms, is missing or improperly seated, since this disrupts water flow and pressure in a similar way.

The most common root cause is using the wrong type of detergent, specifically hand dish soap, all-purpose cleaners, or any product not specifically formulated for automatic dishwashers. Even a small amount of these detergents can produce a large volume of suds inside the tub. Excessive rinse aid leaking from the dispenser is another frequent contributor, as rinse aid is a surfactant and will foam aggressively if it enters the wash water in large quantities. Physical causes include bowls, pots, or deep-sided containers loaded face-up in the rack, which capture and trap standing water and can create turbulence or airlocks in the circulation path.

A missing or dislodged diverter disk is a mechanical cause that is often overlooked. This component sits in the sump area and physically redirects the pump output. Without it, water routing is disrupted and the pump may cavitate, pulling air instead of water. Diagnosing this requires inspecting the sump at the base of the tub after removing the lower spray arm and filter assembly.
