Liebherr F11: Water drainage failure detected in Dishwasher; drain pump cannot evacuate water within safety time limit.
Water is not being pumped out. Drain pump is blocked, drain hose is kinked or blocked, or non-return valve is stuck.
Check and clean the filters in the dishwasher tub. Inspect the drain pump impeller for obstructions. Ensure the drain hose is clear and properly installed.
Dishwasher circulation pump error.
The main wash motor (circulation pump) is blocked, has failed, or the control board is not sending power to it.
Check the pump for blockages. Test the motor windings for continuity. Check voltage from the control board during the wash cycle. Replace pump or control board as needed.
Dishwasher pressure switch fault.
The control board has detected a fault with the pressure switch (level sensor), which may be stuck on or off.
Check the pressure switch tube for blockages. Test the switch for correct operation (continuity changes with pressure). Replace the pressure switch if defective.
Dishwasher heating element fault.
The water is not heating. The heating element is faulty, or the relay on the control board has failed.
Test the heating element for continuity. Check for voltage being sent to the heater during the wash cycle. Replace the heater or control board.
Fan motor failure in freezer.
The evaporator fan motor in the NoFrost freezer is not running or is blocked.
Check for ice buildup obstructing the fan blades. Manually spin the fan to see if it moves freely. Test for voltage at the fan motor. Replace motor if it's receiving power but not running.
Charcoal filter error in wine cooler.
The system has detected that the active charcoal filter needs replacement or the sensor is faulty.
Replace the active charcoal filter. If the error persists, check the sensor or reset the filter timer according to the user manual.
Induction hob power board fault.
Error on the left side power module of the induction hob.
Disconnect power to the hob for 10 minutes. If error returns, the left power board likely needs professional diagnosis or replacement.
Display shows 'NA', indicating a power failure.
The appliance has experienced a power interruption. The displayed temperature is the highest temperature reached during the outage.
Press the 'Alarm' button to silence the audible warning. The display will then show the current temperature. Check food for safety.
Display shows 'PF', indicating a power failure.
The appliance has experienced a power outage.
Acknowledge the error by pressing any button. The appliance will resume normal operation. Check food for spoilage if the outage was lengthy.
Induction hob power board fault.
Error on the right side power module of the induction hob.
Perform a hard reset by cutting power at the circuit breaker for 10 minutes. If fault persists, the right power board may have failed.
General communication error between boards.
Communication fault between the display board and the main power board.
Check the wiring harness connecting the two boards, especially around the door hinge area. Reseat connectors. If the error persists, one of the boards may be faulty.
Touch control panel error.
A button on the touch panel is stuck, or the panel has a general malfunction.
Clean the control panel surface thoroughly. Perform a power reset. If a specific button area is unresponsive, the touch control unit may need replacement.
Wine cooler ventilation fan fault.
The internal circulation fan is blocked or has failed.
Ensure vents are not blocked by bottles. Listen for fan operation. If silent, test the fan motor and its connections. Replace the fan motor if faulty.
Water filter replacement indicator is illuminated.
The internal water filter has reached the end of its service life based on time or water volume.
Replace the water filter cartridge with a new one. Follow the manual to reset the filter indicator light.
Appliance lights and display work, but it does not cool.
The appliance is in 'Demo Mode' or 'Showroom Mode'.
Consult the user manual for the specific key combination to exit Demo Mode. Often involves holding a combination of buttons like 'SuperFrost' and 'On/Off' for several seconds.
The temperature display shows a flashing minus sign (-).
Indicates a sensor fault, similar to an F-code, but on a different model series. The specific sensor depends on the compartment.
Identify which compartment's temperature is flashing. This points to the faulty sensor (e.g., freezer air sensor, fridge evaporator sensor). Test and replace the relevant sensor.
Interior lights, display, and alarms are off.
The appliance is in Sabbath Mode, which disables electronic displays and automatic functions for religious observance.
Refer to the user manual to find the specific key combination to exit Sabbath Mode. This is a feature, not a fault.
SuperFrost light is on or symbol is displayed.
The SuperFrost function is activated to rapidly freeze fresh food.
This is a normal function, not an error. It will automatically switch off after approximately 65 hours or can be manually deactivated.
Audible alarm and flashing temperature display.
The internal temperature has risen above the safe threshold, often after initial setup, loading warm food, or a power outage.
Press the 'Alarm' button to silence it. Allow the appliance several hours to return to the set temperature. If the alarm returns, check door seals and for cooling system faults.
