I have a dishlex 450 and for some reason it stops part way through a cycle. It runs for about 4 to 8 minutes then just turns off. There is no error message on the control panel. You can restart the machine and forward it onto the rinse cycle and that drains the water away. I did notice that the water was cold so maybe the heating cycle is not working.
