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. |
|
