The F06 error code on Bosch washing machines indicates a problem with the thermistor (NTC), also known as the Negative Temperature Coefficient sensor. This sensor plays a crucial role in measuring the water temperature during the wash cycle.

The F05 error code on Bosch washing machines signifies an uncontrolled motor start-up. This means the motor begins spinning unexpectedly, potentially creating safety hazards and preventing the washing cycle from running properly. 

The F04 error code on Bosch washing machines typically indicates a problem with the motor or motor control. This could manifest in several ways, depending on the specific model and issue:

Unfortunately, the F03 error code on Bosch washing machines isn't entirely consistent across models. Depending on the specific appliance you have, it could indicate different issues. 

However, here's what I can tell you based on what I know

The F02 error code on a Bosch washing machine typically indicates a heating element problem. This means the water is not reaching the desired temperature during the wash cycle.

The F01 error code on a Bosch washing machine typically indicates a water intake timeout. This means the machine is unable to fill with water within a designated period, preventing the wash cycle from starting. 

There are several potential causes for this error:

The E3 error on a Bosch washing machine unfortunately isn't as straightforward as other error codes. While Bosch uses codes like E16, E18, and E32 more consistently across models, the E3 code can have different meanings depending on your specific Bosch washing machine model.

The E33 error code on a Bosch washing machine indicates excessive foam detected during the wash cycle. This can be caused by a few different factors

The E32 error code on a Bosch washing machine typically indicates an unbalanced load during the spin cycle. This means the laundry inside the drum is unevenly distributed, causing the machine to vibrate excessively and potentially damage itself.

The E23 error code on a Bosch washing machine indicates a potential water leak. This is triggered by the Aquastop system, a safety feature designed to prevent water damage.
