NTC Temperature Sensor & Thermistor

Evaporator anti-freezing protection activated on the air conditioning unit.

Restricted airflow across the indoor evaporator coil due to clogged air filters, a faulty indoor coil NTC temperature sensor, or low refrigerant pressure causing frost buildup on the heat exchanger.

Disconnect mains power, clean the indoor air filters and evaporator fins, and measure the indoor coil NTC sensor resistance with a multimeter (nominal: 5kΩ–10kΩ at 20°C). Verify indoor fan motor speed and refrigerant operating pressures.

Diagnose
E03
Washing Machine
Drainage System & Drain Pump

Machine is not draining water

The drain filter is clogged, the drain pump is blocked or faulty, or the drain hose is kinked or blocked.

Clean the drain pump filter located at the bottom front of the machine. Check the drain hose for obstructions. Inspect the drain pump impeller.

Diagnose
E3
Hob / Cooktop

The mains voltage supply to the hob is incorrect (too high or too low).

This is an electrical supply issue. Turn off the hob at the circuit breaker. An electrician should check the household wiring and the connection to the hob.

Diagnose
E04
Washing Machine
Water Level Pressure Switch & Air Dome

Machine overfills with water or anti-flood system activated

The pressure switch is faulty, or there's a blockage in the pressure switch hose.

Inspect the pressure switch and its connecting hose for blockages or damage. Replace the pressure switch if faulty.

Diagnose
E4
Air Conditioner / Heat Pump
NTC Temperature Sensor & Thermistor

Compressor exhaust high temperature protection

A cooking zone has overheated. This can happen during prolonged use at maximum power or if an unsuitable/empty pan is used.

Check for refrigerant leak, blockage, or faulty exhaust temp sensor. PRO TIP: For communication (E6) and sensor errors, always check the wiring connections between the indoor and outdoor units or sensor harness before replacing parts.

Diagnose
E05
Washing Machine
NTC Temperature Sensor & Thermistor

Airlux E05: NTC temperature sensor signal out of range (open or short circuit) in Washing Machine.

The NTC temperature sensor is faulty (open or short circuit).

Test the resistance of the NTC sensor with a multimeter. Check wiring to the sensor. Replace the sensor if it is out of specification.

Diagnose
E5
Air Conditioner / Heat Pump
Drainage System & Drain Pump

AC over-current protection

Filters are blocked, drain hose is kinked or clogged, or the drain pump is faulty.

Check voltage supply and compressor for over-current conditions.

Diagnose
E6
Air Conditioner / Heat Pump
Electronic Control Board (PCB) & Bus Communications

Communication failure between indoor unit and outdoor unit

There is a communication error between the induction coil and the main control board for a specific zone.

Check wiring/terminal blocks between indoor and outdoor units. PRO TIP: For communication (E6) and sensor errors, always check the wiring connections between the indoor and outdoor units or sensor harness before replacing parts.

Diagnose
E7
Dishwasher
General System & Mechanical Integration

Dishwasher not filling or washing correctly

The flow meter, which measures the amount of water entering, is faulty or blocked.

Inspect the flow meter (often part of the water softener assembly) for blockages or damage. Check its electrical connections. Replace if faulty.

Diagnose
E08
Washing Machine
Drive Motor, Inverter & Tachometer Sensor

Drum does not turn or spins erratically

The motor's tacho sensor, which measures speed, is faulty or has a poor connection.

Check the wiring and connections on the motor's tacho sensor. Inspect the sensor itself for damage. The motor may need replacement if the sensor is integrated.

Diagnose
E8
Air Conditioner / Heat Pump
Electronic Control Board (PCB) & Bus Communications
