Bosch washing machine errors

Despite the fact that the manufacturer has standardized error codes as much as possible for all model ranges of washing machines, some of them, mainly models without an indicator, have different ways of displaying codes and features of their decoding.

Therefore, first we present a table that contains all possible errors of a Bosch washing machine, and then we will consider the features of their display on specific models.

Error codes in Bosch washing machines, their meanings, causes and solutions

Before you start studying errors and searching for a faulty washing machine unit, try restarting the machine by turning off the power for a quarter of an hour.

 

If after this the self-diagnosis system displays an error, you will have to start troubleshooting.

The table shows possible incorrect user actions and breakdowns.

 

At the same time, you need to take into account that in order to diagnose and troubleshoot problems, you will need to disassemble the washing machine and perform some diagnostic measurements. Therefore, if you do not have sufficient experience, it is better to contact a service center.

Service Code What's happened Possible reason and what you can do yourself
F01 F16 The confirmation signal about closing the hatch door was not received. Check that the door is completely seated against the body and that there are no stuck items. Failure of the hatch blocking unit and control elements on the central controller board is possible. The hinges are skewed or the door handle is broken. Error 16 can be reset after closing the door tightly and restarting the program.

F02

F17

There is no water flowing into the washer tank. It is necessary to check the position of the inlet valve, the pressure in the water supply, and the absence of sharp kinks in the inlet hose. Clean the strainer. The fill valve or water level sensor may have failed. Also, error code 17 may appear if the central controller breaks down.

F03

F18

Waste water is not drained. Check the patency of the drainage tract. Clean the drain filter. Check the pump to see if there is any blockage in the impeller. Error f18 Bosch often occurs due to a broken level sensor.
F04 Water leaking from the washing machine. Make sure the drain filter cover is tightly closed. Carefully inspect the drain and inlet hoses, the hatch door seal, the dispenser cuvette, the tank and the fittings suitable for it. If any defects are found, replace the leaking component.

F19

F22

The water does not heat up to the required temperature. Reduced mains voltage, the heating element has burned out, the temperature sensor has failed, the heating element connection relay has failed, the contact in the connecting wires is broken. Failure of elements of the central controller is possible.
F20 The water begins to heat up at a time unplanned by the program algorithm. The temperature sensor, heating element activation relay or central controller is faulty. Before eliminating error 20, you need to check the heating element for a breakdown on the housing.
F21 There is no rotation of the electric motor or it runs jerkily The drive belt has fallen off, broken or stretched. The tank is jammed with a foreign object caught in the gap between the tank and the drum. Wear of the electric motor brushes (for modifications with a commutator motor). Also, error f-21 may appear if one of the electric motor control elements (located in the central controller unit) has failed or there is a breakdown in the controller itself. There may be a malfunction of the tachogenerator or a breakdown of the electric motor itself.
F23 Activation of the leakage protection system (water detected in the pan). Check the condition of the rubber seal of the hatch door, the internal pipelines of the washing machine, the integrity of the volute and pipes, the drain and inlet hoses, as well as the tank. Error 23 also appears when the water detection sensor (installed on the pallet) breaks down.
F25 Activation of the leakage protection system (water detected in the pan). Clean the drain path. The turbidity sensor may have failed or deposits have formed on it. You need to check the connecting wires. Failure or breakdown in the central controller.
F26 Malfunction of the water level sensor in the tank (pressostat) Check the connecting wires between the sensor and the central controller, the pressure switch tube. If necessary, install a new sensor.
F27 No information is received from the pressure sensor Check the connecting wires. The sensor or central controller is faulty.
F28 Flow sensor readings are out of range. Insufficient water pressure from the water supply. There is a blockage in the filling strainer. Fill valve failure, sensor failure or malfunction in the central controller.
F29 After starting the washing program there is no movement of water through the flow sensor Open the water tap completely. Check the pressure in the water supply, the mesh filter of the filling system, and the absence of kinks in the filling hose. Also, error 29 appears in cases where the inlet valve or water level sensor has failed.
F31 Excessively high water level in the tank There is a malfunction or blockage in the drain path, the solenoid inlet valve is jammed, the level sensor or central controller is faulty.
F34 The drum loading hatch is not locked. Mechanical failure of the lock, distortion of the hinges holding the hatch, breakage of wires to the lock fixing mechanism
F36 Malfunction of the loading hatch door locking unit. Make sure the wires are intact. Replace the hatch locking mechanism.
F37 Malfunction of the water temperature sensor in the tank Check the thermostat and the integrity of the wires to the central controller. Error 37 is also displayed when the heating element fails.
F38 Short circuit in the temperature sensor circuit Make sure there are no shorts in the wiring. Most likely the thermistor or one of the elements of the central controller has failed.
F40 The washing machine does not start or programs run with errors. Check the voltage in the network, as well as the presence of electricity in the outlet, the integrity of the power cord, the serviceability of the plug and socket. The start button or central controller may be damaged.
F42 Motor speed too high. Failure or malfunction of the tachometer, faulty connecting wires, triac on the central controller board. The electric motor may have failed.
F43 The drum does not rotate Remove the items and run the washer idle. The drum may be overloaded. The drum is blocked (in such cases it cannot be turned by hand) due to wear of the bearings or objects falling into the gap between the tank and the drum. The tachogenerator is damaged.
F44 The electric motor rotates in one direction only. Make sure there is no imbalance of items in the drum. Check the tachometer, electric motor, as well as the controls located on the central controller board (triac, reversing relay).
F59 3D sensor produces incorrect values Check the connecting wiring to the central controller. Pull out and reinsert the chip. Failure of the sensor or central controller.
F60 Incorrect data from the flow sensor. Check the presence of water and its pressure in the water supply. Clean the strainer. The fill valve, flow sensor or pressure switch may have failed.
F61 The drum loading hatch is not locked Mechanical failure of the locking mechanism. . A break or defect in the wiring from the lock to the central controller.
F63 Central controller software failure. Restart the washer by turning off the power for a quarter of an hour. If the operation of the washing machine is not restored, repair or replacement of the central controller board is necessary.
F67 Failure of electronic components on the central controller board. Diagnostics, repair and installation of a new controller board. Performed in a service center
E02 Critical failure of the electric motor. Check the commutator brushes, the integrity of the electric motor windings, and the tachometer. Error e2 is also displayed when the elements of the central controller fail.
E67 Control controller malfunction. Failures are possible due to voltage surges, wiring problems, as well as failure of the electronic components of the central controller board.

Service codes for Bosch Maxx 5 / 6 / 7 washing machines

The model range includes both washing machines with a display and simpler versions not equipped with a display. But regardless of the modification, error codes for Bosch Maxx 5, 6 or 7 washing machines will always be displayed on the front panel in the form of combinations of lit and inactive indicators. To decipher, use five spin speed LEDs and four washing machine status LEDs. For some code combinations, there are two display options.
