KitchenAid Washer Error Code F3E2 — What It Means & How to Fix It

What Does This Error Mean?

F3E2 means the NTC temperature sensor in your KitchenAid washer has shorted — its resistance has dropped below the minimum the control board accepts. A shorted sensor reports a falsely high temperature, which can cause the control board to shut off the heater prematurely. A shorted thermistor cannot self-recover and must be replaced.

Affected Models

KitchenAid Front-Load Washer
KitchenAid KHFW Series
KitchenAid KHHW Series
KitchenAid Artisan Series Washer

Common Causes

NTC thermistor has internally shorted — its resistance is below the minimum threshold
Two wires in the thermistor harness are touching (shorted), creating a false low-resistance reading
Water ingress into the thermistor has caused a short between its sensing element terminals
Thermistor connector pins are bridged by mineral deposits from hard water
Control board is misinterpreting the thermistor signal due to a board fault

How to Fix It

Unplug the washer for 5 minutes and try a cycle.

A shorted thermistor will not clear on a power reset — the short is a physical hardware failure. However, a reset rules out a transient board fault before investigating the sensor.
Inspect the thermistor wiring harness for any pinched or damaged sections where two wires might be touching.

A harness pinched against a metal bracket or door hinge can create a short between wires without the thermistor itself failing.
Have a technician test the thermistor resistance with a multimeter.

A shorted NTC reads near-zero or very low resistance. A normal thermistor reads several thousand ohms at room temperature.
Replace the thermistor if it tests as shorted.

The NTC thermistor is a small sensor that clips or screws into the tub or water path. It is a low-cost part and straightforward to swap once the panel is removed.

When to Call a Professional

A shorted NTC thermistor cannot reset or recover — it must be replaced. A technician can confirm the short with a resistance measurement and replace the sensor in one visit.

Frequently Asked Questions

Can hard water cause F3E2?

Indirectly. Hard water mineral deposits can bridge the two connector pins on the thermistor, creating a short. Cleaning the connector and pins can resolve this type of F3E2 without replacing the sensor.

Will the washer still fill with water if F3E2 appears?

The washer will stop the cycle when F3E2 is detected. Depending on the cycle phase, there may be water in the drum. Cancelling and draining the cycle manually is safe — F3E2 does not indicate a water or electrical hazard.

How much does a thermistor replacement cost?

A replacement NTC thermistor for a KitchenAid washer typically costs $15 to $40 for the part. With technician labor, the total repair usually runs $80 to $160.
