Drum Jerking
Hi I have Blomberg Washing Machine Model LWF411452AW purchased in Nov 2018. I have an issue, the drum will not spin, I put it in TEST mode and when it gets to the Spinning section the drum moves a few inches like it is trying to spin but then stops and nothing happens. I have done the following...
Drained all the water out of the system and checked the filter, hoses and the Impeller - all OK
I can move the Drum freely by hand
Checked the Belt - All OK
It is a Brush-less Motor so no Carbon Brushes.
When I run the Test sequence E-- comes up at the start but no other error codes appear during the testing
Any help you can give me would be greatly appreciated.

Blomberg LWF411452AW drum jerks and will not spin
- The problem
- On a Blomberg LWF411452AW washing machine, the drum would not spin. In test mode, the spin stage caused the drum to move only a few inches as if trying to start, then stop. No fault code appeared other than E-- at the start of the test sequence.
- Likely cause
- The accepted reply said this type of motor juddering normally points to a faulty motor, a fault on the PCB, or possibly a capacitor-related fault. The exact failed component was not confirmed.
- What fixed it
- No confirmed repair was documented. The accepted advice was that this fault is not easy to troubleshoot further without proper diagnosis. Further diagnosis should be carried out by a suitably qualified appliance engineer.
- Checks to try
- Water drained from the system
- Filter checked
- Hoses checked
- Pump impeller checked
- Drum turned freely by hand
- Drive belt checked
- Test mode run through spin stage
- No additional error codes shown during testing apart from E-- at the start
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Normally when the motor judders like that the motor itself as faulty or there is a fault on the PCB or a capacitor somewhere. It's not really something you can easily troubleshoot.
