Re: BOSCH — WFS4030 gb/02
It is quite normal for these machines to operate with the door open, that is NOT a fault! (Whilst you can set any programme and it will advance through, the only thing it will do it pump then switch off with the door open!)
What is the fault is the 900 LED flashing and that (I think?) relates to a motor fault (i.e Tacho or brushes – usually brushes). Strip and cleaning the motor, replacing the brushes and insuring the insulation reading is OK the likely cure? 😉
