miele g646sc D/W inlet/outlet light flashing

Hello, went to this yesterday. Light flshing on front, reset and got machine to drain then fill, then got voltage (with volt stick) to moter for a few seconds and it cuts back to the inlet outlet light flashing. The cap is ok and there is no hum from the motor, can’t see how motor comes off and it’s £275 so thought i’d check on here before getting involved.
