Access our premium database of error codes, common faults, and professional repair solutions for Siemens appliances.
Appliance displays 'AL' error code and fails to drain.
The internal temperature is too high. This is usually caused by the door being left open, a large amount of warm food being added, or a recent power outage.
Ensure the door is closed properly. Press the 'Alarm Off' button to silence the audible alarm. The light will stop flashing once the correct temperature is reached.
Hob is in demonstration mode
The hob is set to showroom mode, where controls work but no heat is generated.
Refer to the user manual for the specific procedure to exit demo mode. It usually involves a specific sequence of turning on a zone and pressing a sensor.
Lights and display work but appliance does not cool
The appliance is in 'demonstration' or 'showroom' mode.
Refer to the user manual for the specific button combination to deactivate demo mode. Often involves pressing and holding two buttons (like 'super' and 'temp setting') simultaneously for several seconds.
Heating sensor fault / Oven not heating correctly
The oven's main temperature sensor (NTC probe) is faulty or has a loose connection.
A service technician needs to test the sensor's resistance and its wiring loom, and replace the part if it is out of specification.
Temperature regulation issue in fridge
The refrigerator compartment's temperature sensor (NTC) is faulty.
This requires a technician to diagnose and replace the faulty sensor.
Temperature regulation issue in freezer
The freezer compartment's temperature sensor (NTC) is faulty.
Service technician required to test and replace the freezer sensor.
Water spray pressure too low / Switch fault
Fault with the water switch that directs water to the upper or lower spray arms, or low water pressure in the system.
Check for blockages in the spray arms and filters. If clean, the water switch assembly likely needs to be replaced by a technician.
Siemens E4: NTC temperature sensor signal out of range (open or short circuit) in Refrigerator / Freezer.
The temperature sensor for the freezer's condenser is faulty.
This is not a user-serviceable part. A service call is necessary to replace the sensor.
Siemens E06: Door lock safety interlock fault in Dishwasher; door switch contact fails to close or open.
The sensor that detects if the door is properly closed is malfunctioning.
Ensure the door is firmly closed. If the problem persists, the door latch and sensor assembly likely needs to be replaced by a technician.
Heating circuit error / Water not heating
There is a fault in the heating circuit, most commonly a failed heating element within the heat pump.
This is a complex repair. The heat pump assembly, which contains the heating element, usually needs to be replaced by a qualified technician.
Internal electronics fault
There is a fault within the hob's internal power or control electronics.
Disconnect the hob from the mains power for 5-10 minutes to attempt a reset. If the error reappears, a service technician is needed.
Button is jammed or stuck
A button on the control panel has been pressed for too long or is physically stuck.
Check all buttons and gently press them to ensure none are jammed. Clean the control panel. If the error continues, the control fascia may be faulty.
Siemens E11: NTC temperature sensor signal out of range (open or short circuit) in Dishwasher.
The temperature sensor (thermistor) or its wiring is faulty, preventing the machine from correctly sensing water temperature.
A technician needs to check the wiring and resistance of the NTC sensor and replace it if necessary.
Siemens E14: Operational cycle fault detected during Dishwasher program execution.
The appliance is detecting an issue with the flow sensor that measures the amount of water entering the machine.
Can be caused by low water pressure or a calcified flow sensor. Try a machine cleaning cycle. If it persists, the sensor may need replacement.
E15 error code is displayed, indicating the water protection system has been activated.
The Aquastop flood protection system has been activated due to a leak causing water to collect in the base.
Disconnect power/water. Tilt the appliance forward to drain the base pan and reset the switch. Inspect internal hoses, sump seals, and connections to find and repair the leak source.
Water supply time exceeded
Water tap is closed, water pressure is too low, or the filter in the inlet hose is blocked.
Ensure the water tap is fully open. Check for a kinked inlet hose. Clean the small mesh filter where the hose connects to the machine and at the tap end.
Draining time exceeded / Water not draining
The drain pump is blocked by a foreign object, the pump is faulty, or the drain hose is kinked or blocked.
Disconnect power. Access and clean the pump filter located at the bottom front of the machine. Check the pump impeller spins freely. Check the drain hose for kinks or blockages.
Heat exchanger or dispenser valve fault
A fault with the valve inside the heat exchanger or a problem with the detergent dispenser.
This is an internal component fault. A service visit is required to diagnose and replace the faulty valve or dispenser assembly.
Unexpected heating / Heater relay fault
The control board has detected a fault with the heater relay, potentially causing the element to heat when it shouldn't.
Disconnect from mains power immediately. This error indicates a potentially dangerous fault with the main control board, which requires replacement by a technician.
Filters are blocked / Poor cleaning results
The fine and coarse filters at the bottom of the dishwasher are clogged with food residue.
Unscrew and remove the filter system from the base of the dishwasher. Clean all parts thoroughly under running water before reassembling.
Aquastop activated / Leak detected
Water has leaked into the base pan of the appliance, triggering the flood protection switch.
Disconnect from power and water supply. Tilt the machine forward carefully to drain the water from the base. Locate and repair the source of the internal leak.
Siemens E24: Water drainage failure detected in Dishwasher; drain pump cannot evacuate water within safety time limit.
The drain hose is blocked or kinked, or the drain pump is blocked.
Check the drain hose for kinks. Disconnect the hose and check for blockages. Remove filters inside the dishwasher and check the drain pump impeller for debris. Ensure the pump cover is securely locked.
Siemens E25: Water drainage failure detected in Dishwasher; drain pump cannot evacuate water within safety time limit.
The drain pump impeller is jammed by a foreign object like a piece of glass, a pip, or food debris.
Remove the filters to access the pump cover. Open the cover and carefully remove any debris blocking the impeller. Check that the impeller can spin freely.
Siemens E27: Operational cycle fault detected during Dishwasher program execution.
The power supply voltage is below the required operating level.
Check the household electrical supply. Consult an electrician if the problem is persistent, as it is an external issue, not a fault with the appliance.
No water detected during fill
Similar to E17; no water is entering the drum. This can be due to a closed tap, low pressure, or a faulty aquastop or inlet valve.
Check that the water supply is on and the hose is not kinked. Clean inlet filters. If the issue persists, the inlet valve may be faulty.
Imbalance error / Cycle finishes without final spin
The laundry load is unbalanced (e.g., a single heavy item like a bath mat). The machine has skipped the final spin to prevent damage.
The cycle has ended. Open the door, redistribute the laundry more evenly, and run a separate 'Spin/Drain' cycle.
Siemens E61: Door lock safety interlock fault in Washing Machine; door switch contact fails to close or open.
Incorrect signal from the door lock or a system communication issue with the door.
Turn the programme selector to 'Off'. Wait 5 seconds and then try to start the programme again. If it persists, service is required.
Module coding is incorrect / Appliance is unresponsive
There is a software mismatch or corruption on the main control board. Can happen after a part replacement if not coded correctly.
This fault requires a service technician with diagnostic tools to reprogram or replace the main control module.
Door locking mechanism fault
The door lock for the pyrolytic (self-cleaning) function is faulty or jammed.
Turn the oven off at the mains for 5 minutes and then turn it back on. If the error code reappears, the door lock mechanism needs to be checked or replaced.
Control panel communication error
A communication fault has occurred between the main control board and the user interface.
Disconnect the oven from the power supply for at least 30 minutes to reset the electronics. If the error returns, service is required.
