Error codes for Bosch washing machines

2024 Author: Priscilla Miln | [email protected]. Last modified: 2023-12-16 00:21

Modern washing machines are able to independently recognize and identify faults that occur in them. Self-diagnostic systems have advanced to the point where a problem with an electrical appliance is recognized as it occurs and prevents it from developing to a critical state. Although each manufacturer has its own self-diagnosis system. And the principle of operation is approximately the same for everyone.

The self-diagnosis system is designed in such a way that when a malfunction occurs, a special code is displayed on the display of the washing machine. As a rule, in addition to the error code, there is no more information on the display. You need to find out what kind of failure the appliance reports. Of course, you don’t need to memorize all the codes and their decoding, you just need to find the instruction manual for this machine or see the decoding in the text below.

Some errors in the Bosch washing machine the user is able to fix on their own. And for some -professional intervention and deeper diagnostics will be needed.

Errors washing machine "Bosch". Loading door not closed

Among the errors of the Bosch washing machine, F01 occurs, perhaps, most often. This means that the loading hatch is not closed. The first thing to do is to check if the hatch is tightly closed, if there are any things sandwiched between it and the wall of the washing machine housing. You should re-stow things in the car, close the hatch and try to restart the program. If this does not help, it is recommended to completely disconnect the washing machine from the mains and check the voltage level in the mains, eliminate the difficulties and reconnect the machine. In the event that this attempt was unsuccessful, you need to contact the master, who, when partially disassembling the Bosch car, will check whether power is supplied to the hatch lock.

Problem codes may vary depending on the model. So, the errors of the Bosch Max 5 washing machine are slightly different in coding. The problem with the open hatch door is displayed with the code F16.

Water is not drawn. What's the matter?

Error E17 in the Bosch washing machine appears on the display if there is no water supply to it. A lot of events can be the cause. We indicate those that are most common in everyday practice:

• The tap for water supply to the washing machine is closed. Often, the user simply forgets to turn on the faucet, which he or his household turned off afterprevious wash. Therefore, the first thing to do is to check the condition of the water supply tap.
• Little or no water pressure. Check the water pressure at any of the faucets in the bathroom or kitchen. If the pressure in the water supply is weak or there is no water, you must contact the city utility service to clarify the causes and time to fix the breakdown.
• No water filter. If a water filter is not installed on the pipes in the house, the fine mesh filter installed at the junction of the solenoid valve and the inlet hose is often clogged. The dirty mesh needs to be cleaned and put in place, after that try to restart the wash.

You can't do without a technician if all the above points are checked, but the washing has not started yet. A professional will open the washing machine and be able to check the power supply to the dial valve.

Code F02 is also the same as code F17. If you see error 17 with the letter F on the screen of the Bosch washing machine, start looking for the reason for the lack of water supply.

Water won't drain

F03 indicates that the water from the machine has not been drained. In the Bosch washing machine, a time interval of 10 minutes is automatically set, during which all the water from the machine must be drained. If this does not happen, then similar errors occur in the Bosch washing machine. Causes and remedies for this:

• The sediment filter is clogged. At the bottom of the washing machine we getfilter, wash it, clean it and put it back.
• Clogged in hose or drain pipe. We also inspect everything carefully for blockage, and if it is present, then get rid of it.
• Faulty drain pump. The coil in the pump must be replaced if the resistance in it is less than 200 ohms. Also, the impeller in the coil should turn freely to the left and right.
• Faulty electronic control unit. In this case, the drain pump is not powered.

Water leak

When the Bosch washing machine gives an error code 04, you need to unplug the appliance as soon as possible. This indicates that there is a water leak. The reason may be a violation of the sealing of the tank in the washing machine. Loose drain hose clamps or hose clamps may also cause water to leak during washing.

Electric motor failure

Error F05 indicates that the motor is defective and starts without a command. The motor control circuit is checked and repaired or completely replaced.

F18. Common problem

In the Bosch washing machine, error E18 or F18 means that the time to drain the water has been exceeded. The reasons for this may be:

• Faulty drain pump, as in error F03.
• Faulty pressure switch - this is a water level sensor. Occurs in the event of a breakdown of the pressure switch switch, or level No. 1 is not reached in the pressure sensor. It is recommended to replace the sensor with a known working one and checksystem.

After the pressure switch and the drain pump were checked and, if necessary, replaced, error 18 appeared again in the Bosch washing machine, you should check the operation of the power unit. Most often, when the readings of the water sensor do not change their readings for 90 seconds, the washing program is reset and the error "important malfunction" is displayed.

Water does not heat up. Serious malfunction

Errors of the Bosch Max 5 washing machine and other models of this company with a value of F19 appear on the display when the water heating system is disturbed. That is, in the allotted time in the car, the water was not heated to the desired degree. The first thing to check is the heating element. See if the heating element is intact, and if there is any current leakage. The next thing to check is how the thermistor works and if there is any damage to the wiring. The third reason may be insufficient voltage in the electrical network. Experts always recommend using a voltage stabilizer when operating an automatic washing machine in order to avoid such problems in advance. It is also necessary to check whether there is a power supply to the heating element. Sometimes the problem is the power unit is defective and needs to be replaced.

Incorrect water heating

Code F20 can be seen on the screen of an automatic washing machine if water is heated, which was not included in the programwashing. With this problem, the machine immediately goes into the "major fault" mode, and the washing program is reset. The "incorrectly" heated water is drained from the tank.

The most common problem is the failure of the NTC sensor. This is a sensor that controls the temperature of the water heating. It is required to install the working part and check the correct operation of the washing machine again. If the error is displayed again, you need to check the heating switch relay. Perhaps this is the problem. Or, in the worst case scenario, there was a software glitch.

Important breakdown

Error F21 in the Bosch washing machine is "critical fault". It will not be possible to solve such a problem on your own, so, in any case, you will have to call a professional. What could be wrong:

• short circuit of triacs on motor control;
• breakdown of the tacho generator;
• faulty operation of the engine reverse relay;
• engine lock;
• drum lock;
• faulty control board.

Most often, error 21 in the Bosch washing machine occurs when the motor does not rotate, or rotates incorrectly. The machine makes several attempts to start the program. And in the event of a malfunction, it completely blocks the washing program.

Water heating sensor malfunction

This means that the NTC sensor is broken, which is responsible for heating the water. An error occurs if the water in the tank has not been heated during the time allotted for this process. The reasons for this may be different:

• NTC sensor shorted;
• wiring problems;
• contacts oxidized.

The temperature sensor needs to be changed. If the replacement did not eliminate the error, the whole thing is in the power control unit. And it should also be replaced with a new one.

Water leaking into the pan

F23 is displayed on the display of the automatic washing machine when there is water in the washing machine tray. In this case, the washing program is automatically interrupted. The reason for this may be a water leak in the hydraulic system of the washing machine or in the tank. It is necessary to check the tank for leaks and replace it if necessary. The second reason can be a breakdown of the aquastop, it works outside the mode of the programmed program. Accordingly, if the malfunction cannot be repaired, the aquastop will have to be replaced.

Software failure

Code 40 tells the user that the automatic washing machine is not working properly. That is, a failure occurs during the entire washing program. Washing stages and cycles occur with temporary failure and critical violations. There are two main reasons:

• There was a power surge. Check the mains voltage, if possible, connect the stabilizer and restart the washing program.
• There was a failure on the control module board. The module needs to be replaced and the board needs to be thoroughly inspected and repaired.

Error 59

Numbers 59 on the displayBosch automatic washing machine gives a signal that the number of revolutions in the washing process does not match the one put into the system. This can mean, as well as an excess of the number of revolutions, and, conversely, their insufficient number. The reasons for this may be a malfunction of the 3D sensor or damaged wiring. Another reason may lie in the incorrect operation of the processor or the program of the washing machine itself. When diagnosing in a Bosch typewriter, they first check the wiring for damage, breaks and integrity. Then they look at the state of all the above sensors, and in what position the magnet is located.

Faulty control module

Error F63 indicates that there is a problem in the functional protection. And, more precisely, a breakdown in the control module. You should try restarting the washing process. If that doesn't work, you need to call a specialist and be prepared for the fact that the control module will most likely need to be replaced.

This list contains the most common Bosch washing machine errors that may occur during its operation. It happens that when a simple malfunction occurs, you still have to call a specialist. This indicates that the code on the display was hiding not one problem, but several at once.

You should not try to repair the washing machine yourself if you are not a specialist. Inept actions can only aggravate the situation. Automaticwashing machines are very expensive equipment, so its operation and repair should be approached constructively and responsibly.
