Sounds like a problem with the pressure switch - a round air operated unit located in the top of the machine. It tells the machine if there is still water in drum. sounds like its giving a faulty signal. either the air tube or the vessel attached to it is blocked or switch contacts are welded closed. also check the filter - some machines have a combined filter and pressure vessel.
