Alarm sounds, high temperature in the refrigerator section.
The door has been left open, a large amount of warm food was added, or there is a cooling system fault.
Ensure the door is fully closed and the seal is intact. Allow the appliance time to cool down. If the alarm persists, it may indicate a fault with the cooling system.
Alarm sounds, high temperature in the freezer section.
Freezer door left ajar, prolonged power outage, or a sealed system fault (e.g., refrigerant leak).
Check that the freezer door is closed properly. If there was a power outage, wait for it to stabilize. If the temperature does not drop, it requires a service call.
A continuous beep or alarm from the appliance.
The refrigerator or freezer door has been left open for an extended period (usually over 1-2 minutes).
Identify which door is open and close it securely.
Dishwasher not filling with water.
Water supply tap is off, inlet hose is bent or blocked, or low water pressure.
Check that the water tap is open. Inspect the water inlet hose for any kinks. Clean the mesh filter where the hose connects to the tap.
Water not draining from the dishwasher.
Filters inside the dishwasher are blocked, drain hose is kinked, or the drain pump is obstructed.
Remove and thoroughly clean the filters in the bottom of the dishwasher. Check the drain hose for blockages. Inspect the drain pump impeller for debris.
De Dietrich D03: NTC temperature sensor signal out of range (open or short circuit) in Washing Machine.
The heating element has failed, there is a wiring issue, or the temperature sensor (NTC) is faulty.
This usually requires a technician. The heating element and temperature sensor need to be tested with a multimeter and replaced if faulty.
Anti-flood system activated, possible leak.
A leak has been detected in the base of the machine, activating the flood protection switch.
Turn off water and power. Tilt the machine forward to drain water from the base tray. Identify and repair the source of the leak (e.g., split hose, bad seal).
De Dietrich D05: NTC temperature sensor signal out of range (open or short circuit) in Dishwasher.
The NTC (temperature sensor) is faulty or has a poor connection.
Requires a service engineer to test the NTC sensor and its wiring. The sensor will likely need to be replaced.
Dishwasher will not start, door error.
The door is not correctly latched or the door lock mechanism has failed.
Open the door and close it again firmly. If the error persists, the door latch assembly may need to be repaired or replaced.
Overfill or foaming issue.
Too much detergent has been used, causing excessive foam, or the pressure switch is faulty.
Run a rinse and spin cycle to clear the foam. Use less detergent in future washes. If the problem continues, the pressure switch may need checking.
Freezer not defrosting correctly, ice buildup.
The defrost sensor in the freezer compartment is faulty.
This error requires a technician to access the evaporator area, test the defrost sensor, and replace it if it's out of specification.
Oven temperature reading is incorrect or not heating properly.
The temperature sensor (probe) is faulty, indicating an open circuit.
Disconnect the oven from power. Check the connection of the temperature probe. If the connection is good, the probe needs to be replaced.
Oven is unresponsive or displaying an error.
Internal electronic fault on the main control board (PCB).
Perform a hard reset by turning off the oven at the circuit breaker for at least 30 minutes. If the error returns, the control board needs to be replaced.
Oven is overheating or temperature is erratic.
The temperature sensor (probe) is short-circuited.
The temperature sensor needs to be tested and almost certainly replaced by a qualified technician.
Door will not lock or unlock, especially for pyrolytic cleaning.
The door locking mechanism motor has failed or is jammed.
Wait for the oven to cool completely. Try to manually operate the lock. If it remains stuck, the door lock motor assembly requires replacement.
Oven stops during cooking and displays error.
Overheating has been detected, often due to a faulty cooling fan or blocked ventilation.
Ensure the oven's ventilation slots are not blocked by kitchen items. Check if the cooling fan is running when the oven is hot. If the fan is not working, it will need to be replaced.
