Kevin Sandall's procedure also works for the Logixx model and I suspect the Exxcel too. I spent all day cleaning EVERYTHING underneath, pipes, pumps and photo sensor, and the heat exchanger stuff on the side in my Logixx dishwasher and now it all works again including the "auto" program which hasn't worked for ages (machine stalled mid cycle). So nothing had failed, it was just very dirty internally which stopped it working cost to fix £0 + 3-4 hours time. So don't throw it out until you've tried cleaning it. Just be careful when prising apart the plastic clips which hold the molded parts together also watch out for sharp edges when you remove the door panel. I took loads of photos as I took it apart which was a great help the following day when I put it back together, take pictures of the pipework and all the electrical connectors. I found I could unhook the door return spring cables without tipping the diswasher onto the door (so water doesn't run out).
