Amana Dishwasher Error Code F3 E2 — Temperature Sensor Fault
What this means
Error code F3 E2 indicates the dishwasher's water temperature sensor (thermistor) is reading outside its expected range. The sensor may be shorted, open, or disconnected. The dishwasher cannot properly regulate water heating temperature for wash and sanitize cycles.
Alternate codes: F3E2
Step-by-step fix
4 stepsReset the dishwasher
Turn off the circuit breaker for 5 minutes, then restore power. Run a normal wash cycle to see if the error clears.
A temporary sensor glitch from a power fluctuation can cause a false F3 E2 code.
Check the hot water supply
Run the kitchen hot water faucet for 2 minutes before starting the dishwasher to ensure hot water is reaching the unit.
If your water heater is set below 120°F, the dishwasher sensor may flag abnormally low temperatures.
Test the thermistor
Unplug the dishwasher, remove the lower kick plate, and locate the thermistor (temperature sensor) in the sump area. Test resistance with a multimeter — it should read approximately 50K ohms at room temperature.
The thermistor is a small cylinder-shaped component usually near the heating element.
Replace the thermistor
If the resistance reading is far outside the expected range, replace the thermistor. Disconnect the wiring, remove the old sensor, and install the new one.
Make sure the replacement sensor is fully seated and the wiring connector clicks securely.
When to call a professional
If the thermistor tests fine but the error persists, the control board's temperature sensing circuit may have failed.
