Miele dishwasher G2870 scm.

Question

Miele dishwasher G2870 scm. There is an F14 fault. I have cleaned the arms removed the waste basket from the bottom of the dishwasher and removed the two parts one with the large metal ball to expose the plastic wheel clog. There does not appear to be a blockage. I also removed the top arm and cleaned that out. I don't know what other inlets to check as the guide does not tell me exactly what an F14 fault is but explains F11,12,13.Can you help?
