My issue and solution was the same as Denviks. I have a DWD5412 dishwasher and after reading Denviks reply I remembered I'd filled the salt up a day before it stopped working. So I done the 45 degree thing and then I checked the salt, and sure enough the pot was slightly loose, Quick tighten and BINGO all good... To tighten all you need to do is take the lower basket out and tighten the large plastic ring that is located below the salt cap (I don't mean take the cap off and look for it under the cap) It is a large coller type washer, that holds the salt pot in place from above.
Hope this helps
Don't forget that just tilting the machine and getting it working again doesn't mean you've solved the issue,
