KitchenAid Dishwasher Error Code F1E2
Water temperature sensor shorted
Common Causes
- 1Sensor internally shorted
- 2Wiring shorted to ground
- 3Water intrusion in connector
Step-by-Step Troubleshooting
- 1
Locate the thermistor in the sump area and disconnect its leads
- 2
Measure resistance — a shorted sensor reads near 0 ohms instead of ~55,000 ohms at room temp
- 3
Inspect the wiring for damaged insulation or bare wires contacting the metal sump housing
- 4
Check the connector for signs of moisture intrusion or corrosion creating a short path
Pro Diagnostic Tip
F1E2 is the shorted twin of F1E1 (open): a short reads near 0 ohms and, unlike the open which pads the cycle out, it sends a false HIGH-temperature signal so the dishwasher skips the heating phase entirely. On KitchenAid models that means dishes come out greasy because the water never reached sanitizing temperature and the cycle finishes suspiciously fast. Inspect the harness for bare wire against the metal sump and the connector for water intrusion — the combined OWI/thermistor is a single replaceable assembly, so confirm the short is in the sensor and not the harness first.
