Novomatic Error Codes & Diagnostics

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

Luxury front-loading washing machine in brushed titanium with illuminated dark glass drum
CodeAppliancesFault / DiagnosticsRepair InstructionsAction
A1
Refrigerator / Freezer
General System & Mechanical Integration

An alarm is sounding and a warning light is on.

This is a high-temperature alarm for the freezer, not a fault code. It indicates the internal temperature is too high.

Check that the door is fully closed. Avoid opening it for several hours to allow it to cool down, especially after a power outage or loading new groceries. If alarm persists, there may be a cooling system fault.

Diagnose
AL01
Dishwasher
Drainage System & Drain Pump

Dishwasher has stopped and is beeping, may have water in the base tray.

A water leak has been detected in the base of the appliance, triggering the anti-flood protection switch.

Disconnect power and water supply. Carefully tilt the machine to drain the base. Find and repair the source of the leak (e.g., hose, seal, pump).

Diagnose
AL02
Dishwasher
Water Inlet Valve, Aquastop & Flowmeter

Dishwasher cycle starts but no water enters the machine.

Water supply issue. The tap may be closed, the inlet hose kinked, or the water inlet solenoid valve has failed.

Ensure the water supply tap is fully open. Check the inlet hose for kinks. Clean the filter in the hose connection. Test and replace the inlet valve if necessary.

Diagnose
AL03
Dishwasher
Drainage System & Drain Pump

Cycle finishes with dirty water left in the bottom of the dishwasher.

The dishwasher has failed to drain the water due to a blockage in the filter, drain pump, or drain hose.

Remove and clean the main filter and microfilter. Check the drain pump impeller for obstructions. Ensure the drain hose is not kinked or clogged.

Diagnose
AL05
Dishwasher
Water Level Pressure Switch & Air Dome

Dishes remain dirty after a full cycle.

Problem with the main wash motor (circulation pump) or the pressure switch that monitors its operation. The spray arms may also be clogged.

Remove and clean the spray arms, ensuring the jet holes are clear. Inspect the circulation pump for blockages or failure. Check the pressure switch.

Diagnose
AL10
Dishwasher
Heating Element, Thermostat & Safety Fuse

Dishes are not drying properly and the cycle finishes with cold water.

The water is not being heated due to a faulty heating element or an issue with its control circuit on the main board.

Test the heating element for electrical continuity. Check the wiring to the heater. The main control board may need replacement if the element is good.

Diagnose
F01
Oven / Microwave
NTC Temperature Sensor & Thermistor

Oven is not heating correctly or shows an inaccurate temperature.

The oven's temperature sensor (NTC probe) is faulty, providing incorrect data to the control board.

Test the sensor with a multimeter for correct resistance at room temperature. If the reading is incorrect, replace the sensor.

Diagnose
F02
Oven / Microwave
Heating Element, Thermostat & Safety Fuse

Oven is overheating and may display a very high temperature.

The oven has detected a temperature above the maximum limit, usually caused by a stuck heating element relay on the control board.

Disconnect the oven from power immediately. This fault typically requires the replacement of the main power board.

Diagnose
F03
Washing Machine
NTC Temperature Sensor & Thermistor

Water does not heat, or wash cycle takes excessively long.

The water temperature sensor (NTC) is faulty, giving an incorrect reading to the control board.

Test the NTC sensor's resistance with a multimeter. Check the wiring to the sensor. Replace the sensor if faulty.

Diagnose
F3
Refrigerator / Freezer
NTC Temperature Sensor & Thermistor

Freezer temperature is incorrect or fluctuating widely.

The freezer compartment's NTC temperature sensor is faulty.

Locate and test the resistance of the freezer sensor. If the reading is open circuit, shorted, or incorrect for the ambient temperature, it needs to be replaced.

Diagnose
F04
Oven / Microwave
Electronic Control Board (PCB) & Bus Communications

Oven controls are unresponsive or the display is erratic.

A communication failure between the main power board and the user interface/display board.

Inspect the wire harness connecting the boards for damage or loose connections. One of the boards may be faulty and need to be replaced.

Diagnose
F05
Oven / Microwave
Drive Motor, Inverter & Tachometer Sensor

Oven door remains locked after a self-cleaning cycle.

The motorized door lock mechanism has failed, is jammed, or the control board is not sending the signal to unlock.

Allow the oven to cool completely. Try running a short bake cycle to reset the lock. If it persists, the lock assembly may need to be manually released and replaced.

Diagnose
F7
Refrigerator / Freezer
Refrigeration Compressor, Defrost Heater & PTC Relay

Heavy frost and ice buildup inside a frost-free freezer.

The automatic defrost system has failed. This is often due to a faulty defrost heater element.

Manually defrost the appliance. Test the defrost heater for continuity. Also check the defrost thermostat and timer/control board. Replace the defective component.

Diagnose
F08
Washing Machine
Water Level Pressure Switch & Air Dome

Machine stops mid-cycle, especially during heating.

The heater relay on the control board is stuck, or a pressure switch fault is causing the heater to run when the drum is empty.

This is a serious fault. Check the heating element and its wiring. Inspect the pressure switch. The main control board likely needs replacement.

Diagnose
F09
Washing Machine
Electronic Control Board (PCB) & Bus Communications

Appliance is dead, or lights are flashing erratically with no response.

The memory (EEPROM) on the main control board is corrupt or has failed.

Try unplugging the machine for 30 minutes to perform a hard reset. If the error returns, the control board will need to be reprogrammed or replaced.

Diagnose
F11
Washing Machine
Drainage System & Drain Pump

Machine fails to drain the water.

The main control board cannot detect the drain pump. This indicates an open circuit in the pump's wiring or a failed pump motor.

Check the wiring between the control board and the drain pump. Test the pump's electrical continuity. Replace the drain pump if it has failed.

Diagnose
F12
Washing Machine
Electronic Control Board (PCB) & Bus Communications

Machine is unresponsive, display may be blank or flashing all lights.

There is a communication error between the main control board and the front display board.

Check the wiring harness that connects the two boards for any loose or damaged connections. One of the boards may be faulty and require replacement.

Diagnose
F17
Washing Machine
Door Lock Mechanism & Safety Interlock

The door will not lock, and the cycle refuses to start.

The door interlock mechanism is faulty, or the door is not closing properly to engage the lock.

Ensure the door is closed firmly. Check the door catch and the lock assembly for damage. Test and replace the door lock mechanism if it is defective.
