Bosch electronic washing machines are equipped with self-diagnosis systems. Therefore, in the event of a malfunction, they themselves inform the user about this by displaying a specific code. For each individual error, its own alphanumeric value is assigned. According to it, you can determine not only the breakdown itself, but also the reasons for which it arose, and ways to eliminate it.
Error code F03 means that there is no water drain, which must be at the final stage of the wash cycle. This code is displayed on the display when, 10 minutes after the completion of the process, the water does not drain, but remains in the tank. For the same reason, the spin mode does not work, and the clothes after washing remain completely wet.
Understanding why error F03 is issued, and the water does not drain is not so difficult. You can carry out diagnostics yourself, before the arrival of the master. The causes of failure are often very simple:
After eliminating the causes, restart the machine to reset the error.
If, after diagnosing and trying to reset, the error still appears, then the problem is a malfunction of internal parts. F03 says about failure:
Another reason for the F03 error is a malfunction of the control module. This is a fairly rare breakdown, because the board is considered the most expensive part of any washing machine.
The control block consists of many elements. Separate parts ensure the functioning of the engine, sensors, drain system, and other components. If a short circuit occurs, individual parts may burn out. They need to be soldered or cleaned. Sometimes only installing a new module helps.
