I have had exactly the same happen. Two months before warranty ran out I paid £20 postage to return and have repaired under warranty. I still wasn't 100% happy on its return but it was working, now 1 month after warranty has run out it will not pump any water through, just keeps flooding out of the drip tray, I have taken apart but no joy. I descaled this every 2 weeks and kept up good maintenance. Will be replacing but not with a Dualit.
