KitchenAid dishwasher F3E1 error code
F3E1 does not mean the same thing on every KitchenAid dishwasher. Our data shows 2 documented meanings, depending on which engineering platform the model is built on. Look up your model number to see the one that applies.
| Meaning | Appliance | KitchenAid models |
|---|---|---|
| Thermistor/OWI: open or shorted | Dishwasher | 75 |
| Thermistor/OWI: open | Dishwasher | 36 |
F3E1: Thermistor/OWI: open or shorted
- Brand
- KitchenAid
- Appliance
- Dishwasher
- Code
- F3E1
- Documented meaning
- Thermistor/OWI: open or shorted
- Applies to
- 75 KitchenAid models on 5 platforms
- Can you keep using it?
- With caution
F3E1 means the water temperature reading from the sensor inside the OWI is out of range, either open or shorted; very hot incoming water can also cause it.
What the dishwasher is detecting
The control reads water temperature through a thermistor built into the OWI sensor. A reading too low or too high to be real sets this code.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented An open or shorted wire, connector or part in the temperature-sensing circuit.
- Documented An open, shorted or failed temperature sensor.
- Documented A failed temperature-sensor input on the control.
- Documented Incoming water hotter than about 167°F (75°C).
- Documented A dishwasher used right after being stored in freezing conditions (named on the 2023 platforms).
Safe checks you can make
- Check how hot the water at the kitchen faucet gets; around 120°F is the usual recommendation for dishwashers.
- Switch off the dishwasher's circuit breaker (or unplug it, if it plugs in under the sink) for one minute, restore power and run a short cycle to see whether the code returns.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Checks the sensor and its circuit with power off.
- Verifies incoming water temperature.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher thermistor or turbidity sensor replacement | $180–$330 | Light |
| Dishwasher main control board replacement | $260–$590 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. Heating and sanitizing may not work correctly. Schedule service.

F3E1: Thermistor/OWI: open
- Brand
- KitchenAid
- Appliance
- Dishwasher
- Code
- F3E1
- Documented meaning
- Thermistor/OWI: open
- Applies to
- 36 KitchenAid models on 2 platforms
- Can you keep using it?
- With caution
F3E1 means the control is reading an open circuit from the water temperature sensor, which sits in the same sensor as the soil-sensing (OWI) sensor.
What the dishwasher is detecting
The control reads water temperature from a thermistor built into the optical wash indicator (OWI) sensor. A reading that looks like a broken circuit, far colder than any real water, sets this code.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented An open wire or connector in the temperature-sensing circuit.
- Documented An open or failed temperature sensor (OWI/thermistor).
- Documented A failed temperature-sensor input on the main control.
Safe checks you can make
- Switch off the dishwasher's circuit breaker (or unplug it, if it plugs in under the sink) for one minute, restore power and run a short cycle to see whether the code returns.
- Note whether the code comes back right after a power reset or only after some cycles; that detail helps the technician.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Checks the temperature reading in the service diagnostic cycle.
- Checks the sensor and every connection in its circuit with power off.
- Considers the control input only after the sensor and wiring check good.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher thermistor or turbidity sensor replacement | $180–$330 | Light |
| Dishwasher main control board replacement | $260–$590 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. The dishwasher may still run, but without a temperature reading it cannot heat or sanitize correctly, so results may be poor. Schedule service.

Repair or replace?
A fault code alone rarely justifies replacing a dishwasher. Most F3E1 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 9–12-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
