Bluesky Error Codes & Diagnostics

Access our premium database of error codes, common faults, and professional repair solutions for Bluesky appliances.

Luxury front-loading washing machine in brushed titanium with illuminated dark glass drum
CodeAppliancesFault / DiagnosticsRepair InstructionsAction
E01
Washing Machine
Door Lock Mechanism & Safety Interlock

Bluesky E01: Door lock safety interlock fault in Washing Machine; door switch contact fails to close or open.

The door is not closed properly, the door latch is broken, or the door lock mechanism (interlock) is faulty.

Ensure the door is firmly closed. Check the door latch and lock for physical damage. Test the door lock's electrical circuit and replace the part if it's defective.

Diagnose
E1
Dishwasher
Water Inlet Valve, Aquastop & Flowmeter

Bluesky E1: Water inlet / filling timeout in Dishwasher; appliance fails to fill to minimum operational level.

The dishwasher has not filled with water within the expected time. The water tap may be off, the inlet hose kinked, or the water inlet valve has failed.

Ensure the water supply is turned on and pressure is adequate. Check the inlet hose for kinks. Clean the filter at the connection point. Test and replace the water inlet valve if faulty.

Diagnose
E02
Washing Machine
Water Level Pressure Switch & Air Dome

Bluesky E02: Water level pressure sensor/switch frequency anomaly detected in Washing Machine.

The machine has failed to fill with the required amount of water in the allotted time. This can be due to a closed water tap, kinked inlet hose, blocked filter in the inlet valve, or a faulty water inlet valve or pressure switch.

Check that the water supply tap is fully open. Inspect the inlet hose for kinks. Clean the small mesh filter inside the water inlet valve. If the issue persists, test the inlet valve and pressure switch.

Diagnose
E03
Washing Machine
Drainage System & Drain Pump

Drain fault / Water not leaving

The machine has failed to drain the water. The drain pump filter is blocked, the drain hose is kinked or blocked, or the drain pump motor is faulty.

Unplug the machine. Access and clean the drain pump filter. Check the drain hose for obstructions. Inspect the pump impeller to see if it turns freely. If blocked or faulty, replace the drain pump.

Diagnose
E04
Washing Machine
Water Level Pressure Switch & Air Dome

Bluesky E04: Water level pressure sensor/switch frequency anomaly detected in Washing Machine.

Too much water has entered the drum, or the anti-flood sensor in the base has been activated by a leak. Often caused by a faulty pressure switch or a stuck water inlet valve.

Turn off the power and water supply. Check for leaks. Inspect the pressure switch and its hose for blockages or damage. Test the water inlet valve to ensure it is not stuck open.

Diagnose
E4
Dishwasher
Drainage System & Drain Pump

Overfill or leak detected

The dishwasher has too much water inside, or the flood protection switch in the base has detected a leak.

Disconnect from power. Tilt the machine forward to drain water from the base and reset the float switch. Find and repair the source of the leak (e.g., hose, seal, or pump).

Diagnose
E05
Washing Machine
NTC Temperature Sensor & Thermistor

Temperature sensor (NTC) fault

The control board is not receiving a correct reading from the water temperature sensor (NTC). The sensor or its wiring is faulty.

Test the resistance of the NTC sensor with a multimeter (it should change with temperature). Check the wiring between the sensor and the main control board. Replace the sensor if it's out of specification.

Diagnose
E06
Washing Machine
Drive Motor, Inverter & Tachometer Sensor

Bluesky E06: Motor drive or inverter rotation anomaly in Washing Machine; drum/motor fails to spin at target RPM.

A fault has been detected with the main drive motor. This is commonly due to worn carbon brushes, a faulty tacho coil, or a wiring issue.

Inspect the motor's carbon brushes for wear; replace if they are shorter than 15mm. Check all motor wiring connections. Test the tacho coil and motor windings for continuity.

Diagnose
E09
Washing Machine
Door Lock Mechanism & Safety Interlock

Bluesky E09: Door lock safety interlock fault in Washing Machine; door switch contact fails to close or open.

The laundry load is not distributed evenly in the drum, preventing a safe high-speed spin. Can also indicate worn shock absorbers.

Stop the machine, open the door, and redistribute the clothes more evenly. Avoid washing single heavy items like towels or bathrobes alone. If the problem persists with balanced loads, inspect the suspension legs/shock absorbers.

Diagnose
F1
Oven / Microwave
NTC Temperature Sensor & Thermistor

Oven temperature sensor error

The main control board has detected an issue with the oven temperature probe (NTC sensor), such as an open or short circuit.

Unplug the oven. Access the temperature probe inside the oven cavity. Disconnect and test its resistance with a multimeter (should be ~1100 ohms at room temperature). Replace if faulty.

Diagnose
F2
Refrigerator / Freezer
NTC Temperature Sensor & Thermistor

Refrigerator sensor fault

The temperature sensor in the fresh food (fridge) compartment is faulty.

Locate the sensor in the fridge section. Test its resistance and check wiring for damage. Replace the sensor if the resistance is out of range.

Diagnose
F3
Oven / Microwave
Drive Motor, Inverter & Tachometer Sensor

Door lock mechanism fault

A problem with the oven door lock, often related to the self-clean cycle. The lock motor may be jammed or the microswitch may have failed.

Disconnect power. Inspect the door lock assembly for any visible damage or obstructions. Test the motor and switches for electrical continuity. Replace the entire assembly if faulty.

Diagnose
F4
Refrigerator / Freezer
Refrigeration Compressor, Defrost Heater & PTC Relay

Bluesky F4: Cooling circuit or defrost system anomaly in Refrigerator / Freezer; compartment temperature deviation.

The defrost heating element is not working, which prevents the appliance from removing ice from the evaporator coil.

Test the defrost heater for continuity. Also test the thermal fuse/thermostat which is in series with the heater. Replace the faulty component.

Diagnose
F5
Dishwasher
Water Level Pressure Switch & Air Dome

Bluesky F5: Water level pressure sensor/switch frequency anomaly detected in Dishwasher.

The water level sensor has detected that not enough water has entered the machine for the cycle to run correctly.

Check that the water supply is fully open and has good pressure. Clean the inlet valve filter. Ensure spray arms are not blocked, as this can affect flow readings.

Diagnose
F8
Oven / Microwave
Electronic Control Board (PCB) & Bus Communications

Control panel communication error / Overheating

Can indicate a failure of the electronic control unit or an overheating condition has been detected near the electronics.

Ensure the cooling fan for the electronics is working and vents are not blocked. Allow the appliance to cool down completely. If the error persists, it likely indicates a faulty main control board.
