Franke AL01: Water drainage failure detected in Dishwasher; drain pump cannot evacuate water within safety time limit.
The flood protection system (AquaStop) has been activated. There is water in the base tray of the appliance.
Unplug the dishwasher and turn off the water supply. Tilt the machine forward to drain water from the base. Find and fix the source of the leak before restarting.
Freezer compartment not cooling correctly
Freezer temperature sensor (NTC) fault. The sensor is providing incorrect readings to the control board.
The freezer NTC sensor needs to be tested for the correct resistance value and replaced if faulty.
Water not draining from the dishwasher
Drainage fault. The filter is blocked, the drain pump is jammed, or the drain hose is kinked or blocked.
Turn off the power. Clean the filter system in the bottom of the tub. Check the drain pump impeller for obstructions. Ensure the drain hose is clear and not kinked.
Franke E3: Water/air heating failure in Dishwasher; heating circuit does not reach set temperature.
Heating element or wiring fault. The machine is unable to heat the water to the required temperature.
This is likely an internal component failure. Check the heating element and its connections for continuity. A service technician may be required.
Overfill or leak detected
The anti-flood switch in the base has been activated, usually due to a leak, or the pressure switch has malfunctioned, causing the machine to overfill.
Disconnect from the power supply. Check for water in the base pan. Identify and repair the source of the leak. Check the pressure switch and its hose.
Poor wash results, spray arms not rotating
Worn carbon brushes (<15mm), open circuit on tachometer generator coil, defective 3-phase inverter power stage, or loose harness wiring terminals.
Check the wiring to the diverter valve motor. The valve itself may be jammed or faulty and require replacement.
Oven temperature sensor error
Open circuit in the temperature sensor (NTC). The sensor is disconnected or has failed.
Check the connection of the temperature sensor at the back of the oven cavity. If the connection is secure, the sensor needs to be tested and likely replaced.
Washing machine is not draining
Drain fault. The drain pump filter is clogged, the pump is blocked, or the drain hose is obstructed.
Check and clean the drain pump filter located at the front bottom of the machine. Ensure the drain hose is not kinked. Check the pump impeller for blockages.
Franke F3: NTC temperature sensor signal out of range (open or short circuit) in Oven / Microwave.
Overheating detected by the control board. This could be a stuck heating element relay, a faulty temperature sensor, or a malfunctioning cooling fan.
Disconnect power immediately. Check if the cooling fan operates correctly. Test the temperature sensor for correct resistance. The fault may be with the main control board.
Washing machine pressure switch fault
Pressure switch fault. The switch is stuck on 'empty' or 'full', preventing the cycle from progressing correctly.
Check the tube running from the drum to the pressure switch for blockages or kinks. Test the pressure switch itself for correct operation.
Washing machine door will not lock or unlock
Door lock mechanism fault. The door is not closed properly, or the interlock assembly has failed.
Ensure the door is closed firmly. Check the door lock mechanism and its wiring for damage. The lock may need to be replaced.
Washing machine motor is not turning
Motor fault. The motor's tachometer is not sending a signal, the carbon brushes are worn, or there's a wiring issue.
Check motor wiring connections. Inspect and replace worn motor carbon brushes. If the issue persists, the motor or control board may be faulty.
Water heats continuously or not at all
Heater control fault. The heater relay on the main control board is stuck on or has failed.
This is typically a fault with the main electronic control board (PCB), which will likely require replacement.
Franke F8: Motor drive or inverter rotation anomaly in Oven / Microwave; drum/motor fails to spin at target RPM.
Fault with the motorized door lock, typically during or after a pyrolytic cleaning cycle. The lock may be jammed or the motor has failed.
Allow the oven to cool completely. Try power cycling the appliance. If the lock remains stuck, it may require manual release and replacement of the lock assembly.
Drain pump communication error
A communication error between the main control board and the drain pump, or a fault in the pump's wiring.
Check the wiring harness between the control board and the drain pump for loose connections or breaks. The pump itself could be faulty and need replacement.
Appliance is unresponsive, shows error on display
Control board communication error. The main control board has an internal fault or cannot communicate with another component like the display board.
Perform a hard reset by unplugging the appliance for 15-20 minutes. If the error returns, the main control board likely needs to be replaced.
Alarm sounds and temperature display flashes
High temperature alarm. The internal temperature of a compartment is too high. This could be due to the door being left open, a large amount of warm food added, or a cooling system failure.
Ensure the door is fully closed. Allow 24 hours for the temperature to stabilize after adding new food. If the alarm persists, check door seals and investigate for a cooling system fault.
