Kitchenaid CF: Operational cycle fault detected during Refrigerator / Freezer program execution.
The main control board is unable to communicate with the user interface control board (the display).
Check the wiring harness that runs between the main control board and the display, especially at the door hinges where wires can break. If wiring is intact, one of the two control boards has failed.
Alarm sounds and/or light flashes
A refrigerator or freezer door has been left open for more than a few minutes.
Close the door firmly. Check for items inside that may be preventing the door from sealing. Inspect the door gaskets for damage or debris.
Refrigerator Thermistor Failure
The temperature sensor (thermistor) in the fresh food compartment is open or shorted, preventing accurate temperature readings.
Locate the thermistor in the fresh food section. Check its wiring connection. If the connection is good, the thermistor needs to be tested and likely replaced.
Freezer Thermistor Failure
The temperature sensor (thermistor) in the freezer compartment is open or shorted.
Locate the thermistor in the freezer section. Check its wiring harness for a solid connection. If the connection is secure, the thermistor will need to be replaced.
Kitchenaid F1 E0: Operational cycle fault detected during Oven / Microwave program execution.
A failure has occurred within the main electronic control board (ERC), often related to its internal memory (EEPROM).
Disconnect the oven from power for at least 5 minutes to attempt a reset. If the fault code returns after restoring power, the electronic control board must be replaced.
Kitchenaid F2 E1: Operational cycle fault detected during Oven / Microwave program execution.
A key on the user interface has been detected as being pressed for too long, or the keypad ribbon cable is shorted.
Press CANCEL to clear the code. Clean the control panel surface with a soft, damp cloth. If the error persists, the keypad or entire control panel assembly may need to be replaced.
Oven Temperature Sensor Open
The control board is not receiving a signal from the oven temperature sensor, indicating an open circuit.
Check the wiring connection between the sensor and the control board. Test the sensor's resistance with a multimeter (should be around 1080-1100 ohms at room temperature). Replace the sensor if it tests as open (infinite resistance).
Oven Temperature Sensor Shorted
The control board has detected a shorted circuit in the oven temperature sensor.
Test the sensor's resistance with a multimeter. If the resistance is very low or zero, the sensor is shorted and must be replaced.
Kitchenaid F4 E3: Motor drive or inverter rotation anomaly in Dishwasher; drum/motor fails to spin at target RPM.
The main wash motor (circulation pump) is not running correctly. This could be due to a blockage in the pump, a bad motor capacitor, or a failed motor.
Check the sump area for debris that could be jamming the motor impeller. Check wiring and test the motor capacitor if applicable. The wash motor assembly may require replacement.
Door Latch Assembly Failure
The control board detects a problem with the motorized door latch, which is used for the self-cleaning cycle.
Check for any physical obstruction preventing the latch from moving. Inspect the door latch motor and switches. The entire latch assembly will likely need to be replaced.
KitchenAid F5 E2: Water inlet / filling timeout in Refrigerator / Freezer; appliance fails to fill to minimum operational level.
Defective PTC Heater Pellet / Pulse Solenoid / Microswitch Contacts, open/short circuit in the wiring harness, or faulty connector on the door lock mechanism & safety interlock.
Check door switch and hinges for alignment. PRO TIP: If your fridge is showing any 'E' code and it's under 5 years old, always try a hard reset (unplug 10 minutes) before calling. 60% of the time it clears temporary glitches.
Kitchenaid F5 E2: Door lock safety interlock fault in Washing Machine; door switch contact fails to close or open.
The control board cannot detect that the door is locked. This can be due to an obstruction, a misaligned door, or a faulty door lock assembly.
Ensure the door is closed firmly and there are no clothes caught in it. Check the wiring to the door lock assembly. If the issue continues, the door lock assembly needs to be replaced.
Float Switch Open / No Water Entering
The dishwasher doesn't detect water entering the tub. This could be due to a closed water supply valve, a faulty inlet valve, or a stuck float switch.
Verify the water supply to the dishwasher is turned on. Check the float switch in the bottom of the tub to ensure it moves freely. If water is available, the water inlet valve is likely faulty.
Kitchenaid F7 E1: Water/air heating failure in Dishwasher; heating circuit does not reach set temperature.
The control board has detected that the water is not heating. This indicates a problem with the heating element, the high-limit thermostat, or the control board itself.
Test the heating element and the high-limit thermostat for continuity using a multimeter. Replace the faulty component. If both test good, suspect a control board or wiring issue.
Kitchenaid F8 E1: Water drainage failure detected in Dishwasher; drain pump cannot evacuate water within safety time limit.
The dishwasher is unable to drain water effectively. The cause is usually a clogged filter, a blocked drain hose, or a failed drain pump.
Remove and clean the filter assembly in the bottom of the dishwasher. Check the drain hose for kinks or clogs where it connects to the sink drain or garbage disposal. If the path is clear, the drain pump likely needs replacement.
Kitchenaid F9 E1: Motor drive or inverter rotation anomaly in Dishwasher; drum/motor fails to spin at target RPM.
The electronic control cannot determine the position of the diverter motor, which directs water to the upper and lower spray arms.
Inspect the wiring to the diverter motor. The diverter motor and its associated position switch may need to be replaced as an assembly.
Kitchenaid PO: Cooling circuit or defrost system anomaly in Refrigerator / Freezer; compartment temperature deviation.
This indicator appears after the refrigerator has lost and then regained power.
Press any key to acknowledge the outage and resume cooling. PRO TIP: If your fridge is showing any 'E' code and it's under 5 years old, always try a hard reset (unplug 10 minutes) before calling. 60% of the time it clears temporary glitches.
Kitchenaid SD: Operational cycle fault detected during Washing Machine program execution.
The machine has detected too many suds, often caused by using too much detergent or using non-HE detergent in a high-efficiency machine.
Allow the machine to run through its suds-reduction routine. In the future, use only HE detergent and reduce the amount used per load. Run an empty cycle with vinegar to clean out residue.
Kitchenaid UL: Operational cycle fault detected during Washing Machine program execution.
The clothes inside the drum are not distributed evenly, preventing the washer from spinning at high speed to protect itself from damage.
Pause the cycle and open the door. Manually redistribute the wet laundry more evenly around the drum. Resume the cycle.
