Quick answer
FCE4 on JennAir dishwasher appliances often maps to communication — check your docs.
Model compatibility: JennAir reuses codes across series and model years, so FCE4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

In plain terms: FCE4 is a communication-link fault. Record the code and reset power 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.
