Quick answer
JennAir dishwasher code F8E4: Water in drip tray. Confirm in the model guide.
Model compatibility: JennAir reuses codes across series and model years, so F8E4 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
Typical reading on JennAir controls: F8E4 means water was detected in the base drip tray (overflow protection). Stop the cycle, check for leaks, turn off the supply if actively dripping, then call service. The same characters can map to different service actions across wall ovens, dishwashers, or refrigeration. Verify against your exact model docs. JennAir Appliance Repair provides independent diagnosis — not a manufacturer service agency.
