I have replaced the carbon brushes in my logixx 8 machine after error code F43 appeared .the machine works ok but the washing stays soaking wet on the wash programmes

This error can't be reset, it is a repair job. The code mostly means that the carbon brushes are end of life. You can replace them yourselves with new spare parts.

Please don't type all in capitals. It is hard to read and considered 'SHOUTING'.

Motor carbon brushes burned out and needs to be replaced. You can YouTube the procedure and do it yourself or call a service center and tell them you know precisely was wrong with it and how much to replace the parts and labor. It's a. 45-60 job
good luck

F43 is a motor or motor control board issue.

Check motor connector block
Check motor carbon brushes

Bosch Logix with error code F43 has "a motor fault".

You can reset the error code by the follow steps:
1. Turn the appliance knob to the off or reset position, 12 o'clock.
2. Turn the knob to the 6 o'clock position.
3. Press and hold the spin button and while holding the spin button turn the knob to the 7 o'clock position. Continue holding the spin button for about 5 seconds then release the spin button and now turn the knob to off
When your turn it back on it should have cleared the error code





Check motor connector block
Check wiring
Check motor carbon brushes
Check tacho connections
Check motor

motor brushes on bosch machines typically last 6-7 years its the first thing to check

I have replaced the carbon brushes (20-30 EUR) in my WAS32791 washmachine after error code F43. Machine is OK. To remove code F43 - look at https://www.youtube.com/watch?v=PcFQQWNvBhg. Instead SPIN button in video press left MENU button.

Hi.

If you have Bosch, Baumatic, or any other machine built by Bosch, then F43 is a motor issue:

Error F43 : Motor fault: do an emergency drain through the drain access in the front bottom side (see manual). Open door and check ig the drum rotates free when spin by hand. Disconnect power before performing maintenance.

I just realised that I don't appear to have a comprehensive list of Bosch error codes, but some quick research tells me that F43 is a motor error, usually associated with the motor brushes requiring replacement (Though they may also be sticking and just require removing, cleaning and re-fitting).

Hi from retired Englishman in SW France,

For Bosch Logixx, F42, F43 and F44 all decode as 'motor fault indicated'. Sorry ;-0)
I changed the motor on our Bosch (not a Logixx) at a cost of GBP250! I do expect it to last another 20 years, though.

If this has assisted you please score accordingly.
Thanks and good luck!
