We have collected all the error codes of BOSCH washing machine with a detailed description of the causes of malfunctions, diagnostics and repair. For convenience, arranged in a convenient and understandable table below.
The models with the display show the alphanumeric combination on your display, find it in the table and find out the reason for the error.
Models without a display do not execute the specified program and according to the lit or flashing lights placed on the control panel, you can find out the problem.
| Error code | Description | Causes and solution |
|---|---|---|
| F01 | Manhole cover not tightly closed | Re-close the door hatch WM. Make sure the lock is in good condition. Also the fact that nothing prevents dense opening. |
| F02 | No water is collected. | Check the water pressure in the water system, tap, supply hose, filter. |
| F03 | The machine does not drain. | Check the drain pump, filter and resistance of its winding (200 Ohm), drain hose for blockages. |
| F04 | The hatch door is open | Restart the wash program before re-closing the hatch. |
| F17 | No water intake | The water supply valve may be closed. Check the filter, water pressure. |
| F18 | Water was not drained at the right time. | Check the efficiency of the drain pump (possible clogging), level sensor. |
| F19 | Water is heated for a long time. | Check the heating element for operability (replace in case of breakdown), temperature sensor, power supply voltage. |
| F20 | Heating water at a time when the heating element should be turned off. | Check tubular heater relay and temperature sensor. In case of breakdown, a replacement is needed. |
| F21 | Malfunction of the engine (uneven rotation or lack thereof) | Diagnostics and replacement of the driving triac, motor relay. |
| F22 | Temperature sensor (NTC) has failed. | Install a new sensor. |
| F23 | The system "Aquastop" worked. | It is necessary to check the "Aquastop" and possible leaks. |
| F25 | Breakdown or malfunction of the aqua sensor | Check prosostat, permeability of the drain system. Clean the sensor from plaque. |
| F26 | Pressure switch defective | Diagnostics of the water pressure sensor for performance. Turn the machine off and on again to reset the error. |
| F27 | Incorrect pressure switch setting | Make sure that the pressure switch is properly configured and the sensor circuits are intact. |
| F28 | Water flow sensor out of order. Incorrect volume estimate. | Diagnostics of sensor circuits, replacement. |
| F29 | Flow sensor indicates no water. | Make sure that the water flow and pressure in the water supply system, the pressure switch, the valve and the cleanliness of the filter are in good condition. |
| F31 | The water level exceeds the maximum allowed. | Diagnostics of the pressure switch, electromagnetic valves, pump, filter, drain hose, pipe. |
| F34 | Faulty hatch lock. | Breakage of the electric circuit of the lock or mechanical part is possible. |
| F36 | The lock is out of order. | Failure of the relay or triac control lock. |
| F37 | Defective temperature sensor | The washing program continued without heating. Diagnostics of circuits related to the sensor. |
| F38 | NTC breakdown | Check the operation of the temperature sensor, electrical circuits. Installing a new one. |
| F40 | Sync failed | Voltage does not match acceptable values. Make sure there is no lowering or higher voltage in the network. |
| F42 | Motor speed is too high. | Diagnostics control triac, control module, motor. |
| F43 | The engine does not rotate. | Check tachogenerator, control module, possible mechanical interlocks. |
| F44 | The drum does not want to rotate in the opposite direction. | Check control module, relay and triacs. |
| F59 | 3D sensor out of order. | Possible failures: control module, sensor, electrical circuits, firmware failure. |
| F60 | Water flow sensor shows the value below or above the permissible. | Check sensor and electronic circuits, input filter. |
| F61 | Invalid door signal. | It is necessary to check the mechanical and electrical elements of the door, the electrical circuits of the lock. Turn the machine off and on to reset it. |
| F63 | Breakdown of functional protection. | Software failure, control module processor crash. |
| F67 | Invalid card encoding | Broken control board. Turn off the power for 20 minutes. Check the module, update the software. |
| E02 | Engine failed. | Check the integrity of the motor, electrical circuits, control module. |
| E67 | Incorrect module coding | It is necessary to rewrite the control module or replace it. |
