If you search the internet for “miele washing machine f53” you may get an answer saying that this means the speed sensor, motor, or PCB are faulty. As these together comprise almost half of the machine, you would have to dispose of it and purchase a new machine. I even found one chap unhelpfully quoting it back to a questioner and getting shown that he’d found it via Google. There may be a simple issue which doesn’t involve such drastic maintenance: if the symptoms of your “F53 Technical Error” on your Miele machine include some of the below then consider looking at the carbon brushes on the motor.
- the machine is a number of years old
- the F53 occurs at the point in the cycle when the drum would start to rotate
- no maintenance has been done on the motor
- the machine is relatively well used, say 2-3 loads per day
These brushes are a part that is expected to wear and when they do the motor cannot rotate the drum, which leads the speed sensor to think something is wrong and show the error. The photo attached shows the brushes from our machine and you’ll notice that one is shiny while the other is rough. The rough one wore out some time back while the other kept going, then it also reached the limit of the backing spring and could not contact the armature. No contact = no electricity = no motor movement.
We decided to take a chance and ordered replacement parts rather than the full motor, and having found a good Youtube video explaining how these were fitted we undertook the job ourselves. We didn’t even take the motor out of the body as it is accessible by removing the front panel. Once done correctly the motor whirred into life and we’re back washing. A win for DIY and a little hard work.
