Foster E01: Door lock safety interlock fault in Washing Machine; door switch contact fails to close or open.
The washing machine door is not securely closed, or the door interlock mechanism is faulty.
Push the door firmly until you hear a click. Check for clothing caught in the door. If the problem continues, the door lock assembly may need replacement.
Foster E1: Water inlet / filling timeout in Dishwasher; appliance fails to fill to minimum operational level.
The appliance is not filling with water. This can be due to a closed water tap, a kinked or blocked inlet hose, or a faulty solenoid valve.
Check that the water supply is on and the tap is open. Inspect the inlet hose for kinks or blockages. Test the solenoid inlet valve.
Foster E02: Water inlet / filling timeout in Washing Machine; appliance fails to fill to minimum operational level.
Machine is not filling with water in the allotted time. The water tap is closed, inlet hose is kinked, or the water inlet valve is blocked or faulty.
Ensure the water supply tap is fully open. Check the inlet hose for kinks. Clean the filter screen inside the inlet valve connection.
Foster E2: Water drainage failure detected in Dishwasher; drain pump cannot evacuate water within safety time limit.
Water is not being pumped out of the appliance. The drain filter may be clogged, the drain hose could be kinked or blocked, or the drain pump may be faulty.
Clean the drain pump filter located in the bottom of the tub. Check the drain hose for any obstructions or kinks. Inspect the drain pump.
Foster E03: Water drainage failure detected in Washing Machine; drain pump cannot evacuate water within safety time limit.
The machine has failed to drain the water. The drain pump filter is blocked, the drain hose is obstructed, or the drain pump has failed.
Open the small access panel at the bottom front of the machine. Unscrew the filter cap, clean out any debris, and check if the pump impeller can turn freely.
Foster E3: NTC temperature sensor signal out of range (open or short circuit) in Dishwasher.
The water is not reaching the required temperature. This is typically caused by a faulty heating element or a defective temperature sensor (NTC).
Test the heating element for continuity. Check the wiring and test the NTC sensor. Replace the faulty component.
Overfill or leak detected
The anti-flood system has been activated. This can be caused by a leak in the base of the machine or excessive foaming from too much detergent.
Turn off the water supply immediately. Check for visible leaks under the appliance. Tilt the machine to drain water from the base sensor. Use less detergent in the future.
Temperature sensor (NTC) error
The water temperature sensor is providing an incorrect reading, or has an open or short circuit.
This usually requires a technician to test the sensor's resistance and wiring. The NTC sensor will likely need to be replaced.
Foster E07: Motor drive or inverter rotation anomaly in Washing Machine; drum/motor fails to spin at target RPM.
The motor is not spinning or the control board is not receiving a speed signal from the motor's tachometer. This is often due to worn carbon brushes on the motor.
Inspect the motor's carbon brushes. If they are worn down to less than 1cm, they need to be replaced. Also check motor wiring and tacho connections.
Refrigerator sensor fault
The temperature sensor (NTC) for the fresh food compartment is faulty (open or short circuit).
The appliance may run on a default cooling cycle. The sensor, located inside the fridge compartment, needs to be tested and replaced by a technician.
Foster F3: Cooling circuit or defrost system anomaly in Refrigerator / Freezer; compartment temperature deviation.
The temperature sensor (NTC) for the freezer compartment is faulty.
The freezer's cooling and defrost cycles may be affected. The sensor needs to be located, tested, and replaced.
Control board communication error
There is an internal data communication or memory (EEPROM) error on the main electronic control board.
Perform a hard reset by turning off the circuit breaker for 10-15 minutes. If the error returns, the control board will likely need to be replaced.
Door lock fault (Pyrolytic models)
The motorized door lock mechanism has failed to engage or disengage, or the door switch is not registering correctly. Often occurs during a self-clean cycle.
Allow the oven to cool completely. Reset the oven by turning off the power. If the door remains locked or the error persists, the door lock assembly may need service.
Foster H: Cooling circuit or defrost system anomaly in Refrigerator / Freezer; compartment temperature deviation.
The internal temperature in the fridge or freezer is too high. This could be due to a door left ajar, a large amount of warm food added, or a failure in the cooling system.
Ensure the door is fully closed and the seal is clean. Allow several hours for the temperature to stabilize. If the alarm persists, check for cooling system issues like a faulty fan or compressor.
Foster STOP: Door lock safety interlock fault in Oven / Microwave; door switch contact fails to close or open.
Indicates a condition preventing operation, most commonly related to the door lock. The door may not be properly closed, or the door latch switch is faulty.
Open and close the oven door firmly. Ensure nothing is obstructing the latch. If the error continues, the door switch or lock mechanism needs to be inspected.
