F6E3 means the dishwasher sensed foam. Causes JennAir lists, plus the steps to remove suds and run a clean cycle.
Model compatibility: JennAir reuses codes across series and model years, so F6E3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The sensing system detected excessive suds in the dishwasher.
Likely to be fixable at the sink
When a JennAir dishwasher displays F6E3, it is reporting excessive suds. JennAir explains that if its sensing system detects foam, the machine could run poorly or might not take on water.
Where the bubbles originate
The wrong product in the dispenser: laundry detergent, hand soap, or washing-up liquid designed for the sink.
No cap on the rinse aid dispenser after it was topped up.
An oversized dose of regular dishwasher detergent.
JennAir’s foam removal routine
Bail out the foam with a plastic cup, taking as much as you can.
Pull the dishes out of the machine.
Spread 2 to 3 tablespoons of vegetable cooking oil across the tub floor, which suppresses suds.
Start one full cycle with no dishes and no detergent.
Start a second full cycle, fill the dispenser cups with detergent, and leave the dishes out again.
Preventing a second round
Buy products made for dishwashers, measure the dose, and make sure the rinse aid cap is seated. JennAir also recommends a clean-out about once a month (every 30 days or so) and names its affresh dishwasher cleaner. The page describes no deeper fault behind the code and does not tell you to call; still, foam that survives both cycles is a reasonable moment for a technician visit.
Codes with overlapping symptoms
F9E1: long drain, where JennAir repeats the suds advice.
F8E4: water in the drip tray, another place where suds can be a factor.
