My Hoover Optima OPH616/2-80 has stopped working. The door locks, & the drum takes in the water as normal, but then nothing. When I put it on to the spin cycle the water pumps out of the machine but nothing else. There are no additional lights coming on to indicate a fault. I suspect possibly motor brushes, can anyone advise me if this could be the case, & if not possibly point me in the right direction.
