Neff w5320x0gb
Afternoon all.
Have a neff washing machine that has been playing up lately. On Christmas Eve it stopped spinning, washing and all we got was a hum. Checked the drivebelt and brushes and decided brushes needed to be changed. After installing new brushes all worked fine for a few days but for some reason isn't spinning now. Washing cycle is fine but for some reason doesn't want to spin on some cycles. The washer drains fine also.
Anyone any ideas as it's quite old I believe and don't want to keep throwing money at it.

Hello Chris. Humming isn't usually associated with worn carbon brushes. If brushes are worn they either stop making a connection, or they make a very poor connection. In the fist scenario the motor is totally dead, and in the second the motor will turn but erratically, or it will be lethargic and uneven and they is usually a crackling or grating noise caused by sparking between the brush and the commutator.
A humming noise is usually more associated with an induction motor (that has no brushes) or with an electrical fault causing the motor to not receive anywhere near enough power to run but just enough to make it try. Having said that I would check the brushes again, are they smooth where they contact the commutator or is there any charring indicating poor contact? Also check all the connections and pins in the motor and motor plug. If nothing is found it could be a fault on the windings on the motr, or the armature or the pcb.
Also double check that the drive belt isn't loose and the motor isn't slipping inside the belt.

Right. The humming may just be the sound of the pump running, which appears louder if the motor and drum have stopped turning.

Thanks for the reply. Completely stopped doing anything and just got a humming sound from the pump. Took the motor out, fiddled with the brushes again and started working again. The washing machine seems to drain fine but does make a humming sound when spinning from the pump. Don't think the pump is the issue as I would have thought it wouldn't drain properly?
