Haier E0: NTC temperature sensor signal out of range (open or short circuit) in Refrigerator / Freezer.
The temperature sensor in the freezer compartment has failed (open or short circuit).
The freezer NTC thermistor needs to be tested and likely replaced.
Refrigerator sensor fault
The temperature sensor in the fresh food (refrigerator) compartment has failed.
The refrigerator NTC thermistor needs to be tested and likely replaced.
Drain pump error (Condenser models)
The pump that removes condensed water from the reservoir is blocked, or the water level sensor is faulty.
Empty the water container. Check the pump and its filter for lint or blockages. Check the float switch for proper movement.
Haier E3: NTC temperature sensor signal out of range (open or short circuit) in Dishwasher.
The water is not reaching the target temperature. This is likely due to a faulty heating element or a defective temperature sensor (NTC).
Test the heating element for continuity and check its wiring. Test the NTC sensor for the correct resistance.
Communication error between main board and display
The wiring between the main control board and the user interface/display board is loose, damaged, or one of the boards has failed.
Inspect the wiring harness connecting the two boards. If connections are secure, one of the boards may need replacement.
Haier E5: Water/air heating failure in Tumble Dryer; heating circuit does not reach set temperature.
The heating element has failed, or a thermal overload cut-out (TOC) has tripped and needs resetting or has failed.
Test the heating element for continuity. Locate and test the thermal cut-outs. Replace any faulty components.
Communication error between boards
A fault in the connection between the main PCB and the display board.
Check the integrity of the wiring harness that connects the two electronic boards.
Temperature sensor fault (short circuit)
The NTC temperature sensor has failed by short-circuiting.
The NTC temperature sensor needs to be replaced.
Haier E8: NTC temperature sensor signal out of range (open or short circuit) in Hob / Cooktop.
A cooking zone has overheated. This can be due to empty or unsuitable cookware being left on the zone, or a faulty temperature sensor.
Remove the cookware and allow the hob to cool down. Ensure you are using flat-bottomed, suitable cookware. If the error persists, the sensor may be faulty.
Haier E12: Water level pressure sensor/switch frequency anomaly detected in Washing Machine.
Too much water has entered the machine. This is usually caused by a faulty water inlet valve that is stuck open or a malfunctioning pressure switch.
Turn off the water supply immediately. Drain the machine. Inspect and test the water inlet valve and pressure switch.
Haier ED: Cooling circuit or defrost system anomaly in Refrigerator / Freezer; compartment temperature deviation.
The defrost sensor, located on the evaporator coil, has failed.
Test the defrost sensor for correct resistance values and replace it if faulty.
Haier ER: Operational cycle fault detected during Refrigerator / Freezer program execution.
A fault has been detected with the automatic icemaker module.
Check if the icemaker is turned on and connected. Ensure the water line is not frozen. The icemaker module may need to be reset or replaced.
Touch control panel error
A communication issue with the touch control board, possibly due to moisture or a component failure.
Ensure the control panel is clean and dry. Power cycle the appliance. If the error remains, the touch control board may need replacement.
Oven temperature sensor (NTC) error
The oven's temperature probe is defective (open or shorted) or has a loose connection.
Check the sensor's connection at the control board. Test the sensor's resistance at room temperature. Replace if out of specification.
Haier F2: Motor drive or inverter rotation anomaly in Tumble Dryer; drum/motor fails to spin at target RPM.
The drum motor is not running. The drive belt could be broken, the motor start capacitor failed, or the motor itself is faulty.
Check if the drive belt is intact and properly tensioned. Test the motor start capacitor and the motor windings.
Control board communication error
Failure in communication between the main power board and the user interface.
Check the wiring harness between the control boards for secure connections. A faulty board may need replacement.
Haier F4: Water/air heating failure in Oven / Microwave; heating circuit does not reach set temperature.
The oven has detected a temperature above the maximum safety limit. This can be caused by a stuck relay on the control board or a faulty cooling fan.
Disconnect the oven from power and allow it to cool completely. Check the operation of the cooling fan. The control board may be faulty.
Evaporator fan motor fault
The fan that circulates cold air inside the freezer/refrigerator is not working due to obstruction or motor failure.
Check the fan blade for ice or other obstructions. If clear, test the fan motor and replace if it has failed.
Haier F7: Motor drive or inverter rotation anomaly in Washing Machine; drum/motor fails to spin at target RPM.
Motor is blocked, motor's tacho connection is loose, motor brushes are worn out, or the motor control board is faulty.
Check if the drum can be turned by hand. Inspect the motor's wiring, tacho, and brushes. The motor or control board may need replacement.
Haier F8: Motor drive or inverter rotation anomaly in Oven / Microwave; drum/motor fails to spin at target RPM.
The motorized door lock mechanism has failed to either lock or unlock the door correctly.
Check the door lock assembly for any obstruction. Test the motor and switches in the lock assembly. The entire assembly may need replacement.
Haier F9: Motor drive or inverter rotation anomaly in Dishwasher; drum/motor fails to spin at target RPM.
The valve that switches water flow between the upper and lower spray arms is jammed or has failed.
Inspect the diverter valve for blockages. Test the valve's motor and position switch. The assembly may need replacement.
Haier FC1: Operational cycle fault detected during Washing Machine program execution.
Communication failure between the main control board (PCB) and the display board.
Check the wiring harness and connectors between the two control boards for loose or damaged connections.
Frozen food sensor error.
Defective NTC Temperature Sensor Probe (Thermistor), open/short circuit in the wiring harness, or faulty connector on the ntc temperature sensor & thermistor.
Check thermistor resistance in the freezer.
Humidity sensor needs cleaning
Lint and fabric softener residue have built up on the metal humidity sensor strips inside the drum, preventing accurate readings.
Locate the two metal strips inside the drum. Clean them thoroughly with a soft cloth and a small amount of white vinegar, then wipe dry.
Haier HD: Operational cycle fault detected during Refrigerator / Freezer program execution.
The humidity sensor, often used for crisper drawer climate control, has failed.
The humidity sensor needs to be replaced.
Haier UNB: Door lock safety interlock fault in Washing Machine; door switch contact fails to close or open.
Laundry is gathered on one side of the drum, causing an imbalance during the spin cycle.
Pause the cycle, open the door, and manually redistribute the laundry more evenly inside the drum. Resume the cycle.
