The Motor carbon brushes may be worn .If the drum does not rotate first it will take water.{the drum probably rotates when empty no load ,but will not when loaded hence no fill}.Plug out,remove dispenser drawer,lay on side .motor underneath,brushes held in with 2 screws on back end of motor remove and if they are short 5mm and ends are not smooth Replace
