Siemens dishwasher won't drain - advice sought

    The machine in question is a Siemens SE64630.
    The symptoms are that the exhaust pump runs continuously and doesn't empty the bottom of the washer.
    I have removed all the usual filters and they are clean.
    I then saw the pump cover and using a Torex 20 head, I removed the plastic cover to reveal a fan-like thingy (X in attached image) that spins when I put power back on. The residual water is then squirted back into the unit as though the outlet pipe is blocked. I assume the spinning thingy X is one end of the pump shaft.
    Y and Z (in attached image) appear to be in/out pipes but I assume they have to do with the washing process and not relevant.
    My diagnosis is that beyond the X thingy is the pump blade and outlet pipe. That pipe is blocked - I think, maybe. It joins the nearby main kitchen sink outlet which is free and flowing.
    My questions:
    Is there any point in pushing a thin wire/cable thru' the X and see if I can free the blockage. I am afraid to do it in case I damage the pump.
    Is the only alternative to take the whole washer out (it's built-in) and go after the pump from the outside?

    Any comments/advice appreciated please.

    UPDATE:
    I now think that the pump is NOT working correctly.
    Although it looks like it is spinning, I think it is just vibrating a few degrees clockwise and then a few anti-clockwise.
    If that is so, then the pump is shot.
    Can anyone please confirm that a pump can fail in this way?
