Seems like wren114 might be onto something there.

Oh man, do I know that feeling. I once replaced a dishwasher pump that should have taken an hour. The new pump fit fine, but the drain hose clamp just would not seal right. I had water dripping for two days, taking the whole thing out over and over, before I realized the new hose was a millimeter too short. Drove me crazy.

Just like the weird terms we all click 'agree' on.
