Re: Hotpoint Aquarius WML720 problem
You need to examine the ends of the carbon brushes and also the commutator that the brushes rub against.
The ends of both brushes should be smooth and shiny, if one is pitted or has a charcoal like appearance then they need changing, also the comm should appear smooth and clean, not scarred or discoloured.
Post a pic of the displaced brushes and we could soon tell.
Also worth checking the wiring to the door lock as well, flimsy connections which often burn out. 🙁
