Switch machine on. Lights coming on as normal when selecting settings.No time display is shown. Start light flashing. Press start button but no action, no time display. Start light still flashing! Open door and the drum lamp lights up. Have removed and tested door switch for the two way switching which is fine. Customer says it was working intermittently at first. When it didn’t work, the power was left switched on for a few hours and when they tried pressing start, it sprang into life which makes me think there may be an iffy capacitor on one of the modules. Any Bosch chaps out there had this?
