Affected model seriesJennAir built-in dishwasher — confirm your full model and serial
Quick answer
Quick take: F3E2 ≈ temperature sensor for many JennAir dishwasher controls (model-dependent).
Model compatibility: JennAir reuses codes across series and model years, so F3E2 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: F3E2 is a temperature-sensor out-of-range fault. Professional testing of the sensor and harness is required if a reset does not clear it. Control generations share many JennAir / Whirlpool-family codes, but prompts and cleared-state behavior still vary. Cross-check the manual; book JennAir Appliance Repair if DIY resets do not hold.
