Our dishwasher empties intermittently. The reason appears to be that the non-return valve has broken between the flat piece and the disc, and the disc part is now partially blocking the drain pipe. It is proving very difficult to get it out the way it went in because of the restricted width of the slot and the diameter of the disc. Does anyone have any ideas, short of dismantling the whole thing? Thank you.

Thanks Martin, but the problem is that the old one broke in two in situ. The top half lifts out OK but the bottom half wasn’t attached to it, and it has fallen into the drain pipe. It’s getting the bottom half out that’s the issue.

Aha, that might well work – we’ve tried blowing it back and it gets vertical (sometimes) but that’s it. But I can see that constant water pressure would be more effective than separate lungfuls of air. Will give it a try, thanks!
