Quick answer
F6E8 on JennAir dishwasher appliances often maps to fill detection — check your docs.
Model compatibility: JennAir reuses codes across series and model years, so F6E8 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
In plain terms: F6E8 means fill detection failed. Confirm water reaches the dishwasher, then reset once. Treat this as a plain-language orientation for homeowners. Final interpretation belongs to your model’s documentation and an on-site check by JennAir Appliance Repair when the fault returns.
