    I am replacing the Inlet Hose with its built-in valve (Aquastop).

    So far I've removed the rear, side and (outer only) rear panels. But the Inlet hose connects inside the machine. I think I need to get behind the lower rear panel panel, as attached. Or maybe I need to put the Miele G1143sc dishwasher machine on its side and remove its bottom floor to get inside, from underneath. The panel I've ringed on the attached photo in yellow appears to be soldered / spot welded to the whole back of the machine.

    Any tips would be appreciated on how I can get to fit the hose would be appreciated or just if and how I should / can get behind the panel in the photograph.

    Good and bad news. Lying the machine on its side, and by removing (only) the bottom from underneath I've replaced the the Inlet (Aquastop) hose and removed and cleaned the drain hose. I've also replaced the non-return valve. Alas, this hasn't fixed the problem. So I am still getting the Inlet / Drain warning light flashing then becoming solid. I dunno what more I can try but I would like to see this through to the end.

    The problem is fixed, for now. The issue appears to have been caused by a faulty Flow Meter Circuit Board (FMCB) that is accessed by removing the left hand side panel of the dishwasher. The FMCB is about 1.5" long by 0.5" inches tall and is connected by two orange wires.

    Tapping the FMCB hard a few times, then re-inserting it in it's holder, cured the problem. I suspect the fix may only be temporary. I've heard a Reed Switch or Diode on the FMCB can stick with wear. I'm thinking if it's stuck once it can stick again. So I'll replace the £38 FMCB as soon as the one I've ordered arrives.

    It seems replacing the Inlet (Aquastop) hose and the replacing the non-return valve were not necessary. C'est la vie and I'm pleased the dishwasher is now working.
