Quick answer
F2E2 · UI ↔ control communication · JennAir dishwasher — independent plain-language overview.
Model compatibility: JennAir reuses codes across series and model years, so F2E2 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
What owners usually need to know: F2E2 means the user interface and main control lost communication. One breaker power cycle; recurring faults need board/harness diagnosis. Never assume one forum post or generic chart overrides your rating-plate model. Independent technicians at JennAir Appliance Repair test the live appliance rather than guessing from the code alone.
