Affected model seriesApplies to many JennAir built-in dishwasher installations; match your docs
Quick answer
Quick take: F3E1 ≈ thermistor / owi for many JennAir dishwasher controls (model-dependent).
Model compatibility: JennAir reuses codes across series and model years, so F3E1 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
Homeowner summary: F3E1 means the thermistor or optical water indicator is reporting out of range. Clean the filter/sump area; recurring faults need sensor testing. 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.
