Not sure about your specific problem
Does it fill to about the right level, then stop?
In which case it could be the pump motor which pumps the water around
inside

If it fills a bit, the stops it may be that the sensor which detects
that it is full is faulty, and there is not enough water in there to BE
pushed around

I have a Siemens (basically same company) SE26230GB/12 machine which I
have fixed several times thanks to the marvellous BSH PartFinder site.

With your full number (SGS6312 gives 6 possible specific machines e.g.
GB/12 like mine), you can get PDF exploded diagram of all the parts,
and an order list with prices for those parts.

Over the last 4 years I have replaced a motor, a sensor (the 'fill'
sensor), a switch and am waiting on the thermal sensor (My machine is
running cold, and I am hoping this is the problem - the heating element
looks fine). Total cost ~=A380 (admittedly plus my time, but this is a
DIY NG)

If you are going to take the machine apart you will (probably) need a
T20 sized screwdriver bit (one of those funny star shaped ones). Not
easy to take apart the first time, but not as hard as it may seem at
times, and it does get easier.
