Having moved my washer without the transit bracket I got the 'not filling' message. Pressed restart a couple of times then got F14 and, after a short while, flooding from underneath machine. Followed other suggestions on this site and having done all the key checks to pipes, filters and checking for obvious leaks (finding none), I removed front cover using instructions on this site. Problem turned out to be a broken plastic connection between the pipe that runs from base of drum to a narrower rubber tube that connects to back of control panel (this runs around the left hand side of drum and is secured by the connection to the drum housing - you need to liftt a plastic flap around the edge of the drum to see the pipe). Managed to remove the pipe clip holding the smaller rubber tube and super-glued the broken connection before reconecting rubber tube. Having carefully re-assembled it is working fine. Cost nothing and I can hopefully get a lot more use out of washer as I got two new replacement motors the day before Dyson withdrew their repair service. PS someone else on this site has reported very similar problem to mine, including a waste pipe fitted too high that turned out to be a red herring.
