You may need to totally clean out all the trays and pipes/filters and inlet/outlets as they get filled with gunk over time. Look in your manual and it has a section dedicated to how to clean your W723. This may be whats preventing the water going in the machine. Once the machine is cleaned and water fills the machine but it won't turn/wash or spin when placed on cycle, you may then require new carbon brushes for the motor. Also check your belts and pulleys.
