Amana Dishwasher Error Code F1 E1 — Temperature Sensor Fault
What this means
The F1 E1 error code on Amana dishwashers means the thermistor (temperature sensor) is sending a signal outside the expected range. The dishwasher relies on accurate temperature readings to heat water during wash and sanitize cycles. A faulty thermistor, a loose wire connection, or a failed control board input can trigger this code. In most cases, the sensor itself or its wiring is the problem.
Alternate codes: F1E1
Step-by-step fix
4 stepsReset the dishwasher
Turn off the circuit breaker powering the dishwasher for 5 minutes, then restore power. Run a normal wash cycle. If the code does not return, it was a one-time glitch.
If the code reappears immediately or within the first few minutes of a cycle, the sensor or its wiring is likely at fault.
Locate the temperature sensor
Turn off the breaker. Remove the lower front panel and door panel to access the sump area at the bottom of the dishwasher tub. The thermistor is typically a small cylindrical component mounted near the heating element or in the sump housing.
Take a photo of the wire connections before disconnecting anything so you can reassemble correctly.
Test the thermistor with a multimeter
Disconnect the thermistor wires. Set your multimeter to resistance (ohms). At room temperature, a working Amana dishwasher thermistor should read approximately 10,000 to 15,000 ohms. An open line (OL) or 0 ohms indicates the sensor is bad.
Warm the sensor with your hand for 30 seconds and retest. A working sensor should show a decreasing resistance as it warms.
Replace the thermistor if faulty
Remove the mounting clip, disconnect the old sensor, and install the replacement. Reconnect the wire harness, reassemble the panels, and run a test cycle to confirm the error is cleared.
Also inspect the wire harness for chafing or corrosion, which can mimic a failed sensor.
When to call a professional
If the thermistor tests within range but the error code persists, the electronic control board may have a faulty input circuit. Board-level diagnosis should be handled by a qualified technician.
