Meile G641 Dishwaher red inlet light on?

The dishwasher was working fine, went to turn it on and the red light was flashing, cleaned all the filters but now the filter combination handle has come off. I can take the silver filter off but cannot get the cone filter out and the handle won't go on properly. I have turned the dual to Stop and pushed the on/off and start button together ( do I do this with the power on. If so the machine starts, no water and then the inlet button comes on as a solid light).

Any help would be appreciated.
