I'm a sad Miele appliance nerd 
and hate seeing machines that are easily repaired hit the scrap heap.
F11 - "water drainage fault"
F14 - "water intake fault" <- as well as faulty intake flow meter, this can be caused by a pump pressure level switch error - I didn't even know existed but looks relevant!
F52 - "pump pressure level switch has reset during heating"
F70 - "float switch fault" <- causes drain pump to stay permanently on, probably not a current fault.
Looks like the pump pressure switch is mounted on the side of the pump and can be replaced but actually, if that error is current, it could point at a faulty pump. Looks fiddly but probably worth opening the pump up to see if there's anything stuck in it or the pressure switch / test it.
At this point the economics of repair are slightly stacked against I would say...
