Bosch Washing Machines

There is an issue with the motor, which could involve worn motor brushes, electrical faults, or problems with the motor control module.

The firmware on the control module may have failed or is incorrectly encoded. This can lead to various operational errors.

The washing machine door is not properly closed, preventing the program from starting or completing. This could be due to the door not being shut firmly or an item of laundry caught in the door seal.

The Aquastop system has reported an error, typically meaning it's not responding to low pressure correctly, or a leak is detected. This prevents water from entering the machine.

The washing machine is not receiving water. This could be due to the water tap being turned off, low water pressure, or a blocked inlet hose filter.

The water temperature is not reaching the set value within the expected time. This points to an issue with the temperature sensor or the heating element itself.

The washing machine is unable to drain water from the drum within the expected time. This usually indicates a blockage in the drain system or a faulty drain pump.

The washing machine is unable to drain water to the required level within the allotted time. This is usually due to the drain pump or hose.

The washing machine has detected a water leak. This requires immediate attention to prevent water damage.

The control circuit for the gearmotor (which drives the drum) is not receiving a signal. This could be a fault in the control circuit or the tachogenerator.

The motor is starting unexpectedly or running at incorrect times. This indicates a fault in the motor control circuit.

The NTC temperature sensor has failed, likely due to a short circuit. This affects the monitoring of water temperature during heating.

There is a malfunction in the control circuit for the NTC temperature sensor, or the sensor itself has failed (short circuit). This prevents proper water heating.

The washing machine door is not fully closed or the latch mechanism is defective. This prevents the program from starting.

There is a communication error between the motor and the main control board. This can cause the drum to stop working.

The motor has malfunctioned, potentially due to overheating or a faulty control triac on the board. The drum stops working.

There is a short circuit in the electric motor winding or worn motor brushes. This causes the drum to stop working.

The mains power supply voltage has exceeded the acceptable level (above 318 V). The drum rotation is not affected, but measures should be taken to normalize voltage.

The mains power supply voltage has dropped below the acceptable level (below 172 V). The drum stops working, but the program may continue.

The heating system is malfunctioning, resulting in washing with cold water (below 10 °C) or potentially overheating (above 100 °C).

The wash program cannot start because the machine's door is not securely closed. This is a safety mechanism to prevent water spillage.

The washing machine has taken longer than usual to fill with water. This can be due to a closed water tap, a clogged inlet filter, or low water pressure.

The washing machine failed to drain water within the specified time, similar to F03. This indicates an issue with the drain pump or drainage path.

The water in the washing machine is not reaching the set temperature within the expected time. This could be due to a faulty heating element, low voltage, or scale buildup.

The water is heating at an unintended time during the wash cycle, or the temperature sensor is faulty. This can cause improper washing results.

The washing machine's control system is experiencing issues, or the drive motor is not operating correctly, leading to the drum not rotating. This is often due to electrical faults.

The NTC (temperature sensor) has a fault, either a short circuit, malfunction, or a break in the connecting wires. This will prevent the machine from heating water correctly.

The Aquastop system has been activated, likely due to a detected leak or malfunction within the water intake system. The program is canceled and the door is locked.

The Aqua sensor, which monitors water turbidity, is malfunctioning. This could be due to scale buildup on the sensor, a faulty pressure switch, or a clogged drain system.

The analog pressure sensor is malfunctioning. This is a critical error that protects the machine, resulting in the program canceling, water draining, and the door locking.

The washing machine is having trouble setting or calibrating the pressure sensor. This means it might be operating with incorrect water level values, potentially affecting wash performance.

The flow sensor, which measures the volume of water entering the machine, is reporting an impossible value. This indicates a problem with the sensor itself or its measurement.

The flow sensor is not detecting any water flow, even though water should be entering the machine. This could be due to a closed tap, low pressure, a clogged filter, or a faulty valve.

The washing machine has filled with too much water, exceeding the maximum safe level. This can happen if the pump is blocked, the drain hose is blocked, or the pressure sensor is incorrectly adjusted.

The washing machine door lock mechanism is not engaging correctly. This is a critical error, and the program will be canceled with the door locked.

There is a fault within the door lock system's electronics, likely a module failure. This is a critical error, and the door will remain locked.

The NTC temperature sensor is faulty, causing the program to terminate without heating the water. This requires checking the sensor and its wiring.

The NTC temperature sensor has a short circuit. This will cause the program to end prematurely without heating the water.

An error occurred because the values from the power supply network do not match the permissible operating values for the washing machine.

The motor is experiencing uncontrolled high speeds, likely due to a faulty triac on the electronic module. This is a critical error, and the program will be canceled.

A critical error has occurred, causing the program to cancel, the door to lock, and monitoring processes to halt. This requires a reset and potentially further checks.

The motor is not performing reverse rotation as expected during the cycle. This indicates a fault in the module, possibly a faulty triac or reverse relay.

The 3D sensor is reporting measurement values that are outside the expected range. This can affect speed control and may be due to wiring or sensor failure.

The flow sensor is detecting either too much or too little water flow per unit of time. This could be due to a faulty sensor or turbulence in the water path.

The washing machine is receiving an incorrect signal regarding the door's status (open or closed), or the security lock is activated incorrectly. This is a critical error.

A functional protection error has occurred, possibly due to a defective processor or software error. This is a critical error that locks the door and stops operation.

There is an incorrect encoding between the power module and the control module, or the software versions are incompatible. This is a critical error.
