Quick checks, in order
Record exact conditions
Note cycle stage, load, and whether the code is intermittent.
Power-cycle once
Disconnect power briefly and test one normal cycle.
Check only accessible causes
Clean filters, level the unit, and correct installation.
Use model-specific service
Sensor and wiring tests require qualified diagnosis.
What happens when F3E2 appears?
An open, shorted, or disconnected sensor is possible.
The measured condition may actually be abnormal.
Vibration, moisture, connector, or sensor wear may be involved.
Stop and get qualified help when
- The code involves heat or leakage

- Appliance behaves unpredictably
Official support and model manuals
Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
What does F3E2 mean on a Whirlpool dishwasher?
On many model families, F3E2 indicates that the soil sensor is abnormal. Confirm the exact model and region because the same display can be used differently.
Can I clear F3E2 by unplugging the dishwasher?
A short power reset may clear a temporary state, but it will not fix a blocked hose, leak, failed sensor, motor, heater, or wiring fault. Stop if the code returns.
Should I replace a part based only on the code?
No. A code identifies a system or condition, not always the failed component. Complete safe external checks and use the model-specific manual or qualified service.
