What is the Amana Dishwasher F1E1 error?#
F1E1 on an Amana dishwasher is a temperature-sensor fault: with no trustworthy water-temperature reading, the control plays it safe and runs the wash for its maximum duration, which is why the telltale is a normal cycle that now drags past three hours. It is harmless to run, just slow and poorly heated, so dishes finish under-sanitized. On these budget ADB machines the sensor sits in the wet, warm sump, so the first thing I check is its connector for corrosion before deciding the thermistor bead itself has failed.
F1E1 on a Amana Dishwasher: likely causes and repair cost#
On a Amana Dishwasher, the F1E1 code signals: temperature sensor fault.
| Likely cause | Typical likelihood |
|---|---|
| NTC sensor failure | Most common |
| Wiring fault | Common |
| Connector corrosion | Less common |
Typical professional repair: $75–$175 · Difficulty: moderate · usually a technician job
Symptoms that often accompany F1E1: Wash cycles run far longer than they used to; Water never feels as hot as the cycle promises; A normal cycle now stretches past three hours; Dishes come out under-sanitized; Heated-dry results are weaker than before
Technician diagnostic sequence for F1E1:
- Locate the thermistor sensor in the sump area near the wash pump
- Disconnect and measure resistance: approximately 55,000 ohms at 77F (25C)
- An open circuit or near-zero reading confirms sensor failure
- Trace the sump harness for breaks where it runs past the heat of the wash pump
Parts a technician may check or replace: Thermistor sensor assembly; Sensor harness
Field note: F1E1 on a budget Amana ADB dishwasher is a temperature-sensor loss: with no trustworthy water-temperature reading the control plays it safe and simply runs the wash for its maximum duration, which is why the telltale is a normal cycle that now drags past three hours. Measure the sump thermistor near 55,000 ohms at room temperature; an open or near-zero reading condemns it. Because the sump is a wet, warm spot, check the connector for corrosion before deciding the sensor bead itself has failed.

How to troubleshoot the F1E1 error yourself#
Start with a breaker reset to rule out a one-off glitch — power off for a couple of minutes, then back on; if the marathon cycle returns, the fault is real. From there a homeowner can safely pull the lower rack and filter and look at the thermistor in the sump near the wash pump, checking its connector for the corrosion that a wet sump invites. Trace the harness where it runs past the heat of the wash pump for a chafed or broken wire. What I leave to a technician is the metering: reading the sump thermistor, which should sit near its room-temperature value, and confirming an open or near-zero reading before replacing the sensor. Do not swap the sensor assembly on a guess when a corroded connector might be the whole story.
Is the Amana Dishwasher F1E1 error worth fixing?#
For an Amana this is a straightforward yes. The professional repair in the table above is modest, and the thermistor is an inexpensive part, so restoring proper heating to a working dishwasher costs far less than a replacement — even an entry-level one. The only time I would pause is if the machine is genuinely old and other things are failing with it, since these are budget units where a stack of repairs can outrun a new machine's price. For a single temperature-sensor fault, though, repair is clearly the better spend.

Amana Dishwasher F1E1: frequently asked questions#
What does the F1E1 error mean on a Amana Dishwasher?#
It means the dishwasher lost a reliable water-temperature reading from its sump sensor. Unable to confirm the water is hot, the control runs the wash for its maximum time, which is why a normal cycle now stretches past three hours.
Is it safe to keep using a Amana Dishwasher that shows the F1E1 error?#
It is safe, just inefficient — the dishwasher runs extra-long and never fully heats, so dishes come out under-sanitized. There is no hazard, but I would not rely on it for a proper hot wash until the sensor is fixed.
Can I clear the F1E1 error myself, or do I need a technician?#
You can try a breaker reset and inspect the sump connector for corrosion. Metering the thermistor to confirm it is open, and replacing it, is a technician job, so a persistent F1E1 needs a pro.
How much does it cost to repair the F1E1 error on a Amana Dishwasher?#
A professional F1E1 repair typically runs $75–$175. The thermistor itself is cheap; most of the range is the labor to reach it in the sump, sometimes just cleaning a corroded connector instead.
Which parts usually fail when a dishwasher throws the F1E1 code?#
The NTC temperature sensor in the sump is the usual failure, going open or reading wrong. A corroded connector or a wire chafed by the wash-pump heat can open the same circuit without the sensor bead failing.
Is a Amana Dishwasher with the F1E1 error worth repairing?#
Yes, on a sound machine — the part is cheap and the repair is far less than a new dishwasher. Only if an aging Amana is failing in several places at once would replacement of a budget unit start to make sense.
Why does ntc sensor failure trigger the F1E1 error?#
The NTC sensor's resistance is how the board reads water temperature. When it fails open or corrodes, the board gets no valid reading, so it cannot confirm the water is hot and defaults to the maximum wash time, posting F1E1.
