Beko WM6133S drum turns empty but not with a load

The problem

On a Beko WM6133S washing machine, the drum turns when the machine is empty but does not turn when laundry is loaded. The machine still fills with water and drains normally.

Likely cause

The accepted reply suggests worn motor carbon brushes as the most likely cause if the drum tries to turn or judders, or if the motor makes a crackling or grating noise. Less likely possibilities mentioned were a very slack drive belt, connection faults, the PCB, or internal motor faults.

What fixed it

Check whether the drum tries to turn, judders, or whether the motor makes abnormal crackling or grating noises. Check that the drive belt is fitted correctly and inspect the motor plug connections and carbon brushes for obvious issues. If nothing obvious is found, further diagnosis should be carried out by a suitably qualified appliance engineer. The exact repair was not confirmed in the discussion.
