Indesit washing machine drum turns then stops

Indesit 6125s drum turns briefly then stops, likely motor brush wear

The problem

An Indesit 6125s washing machine fills normally, then during wash the drum turns about 180 degrees and stops. It repeats this after a couple of minutes and then sits idle with no error codes. The machine will drain, but a spin cycle also does not work. The same happens with and without a load.

Likely cause

The strongest diagnosis in the discussion is worn carbon brushes on the motor. A forum reply also noted that a PCB fault was another possibility, but this was not confirmed.

What fixed it

The accepted advice was to check the carbon brushes. The drain blockage theory was discounted because the machine was still draining; the discussion states a drain problem would more likely leave water in the machine and prevent fast spin rather than stop the motor turning. The original poster indicated they might replace the appliance rather than repair it if brushes were the likely fault, but no repair was confirmed.
