The dishwasher wouldn't fill with water.

I first turned off the water to the dishwasher, then the electricity to it, then took off the front bottom access panel, I then unbolted the inlet valve from the side of the machine, undid the electrical hookups remembering which one connected to which, then unclamped the two hoses, I then put the new one back in place, redoing the hoses and electrical and bolting it back to the side of the machine, then putting the front bottom access panel back on, then turning back on the water and electicity. The one thing that may make it easier if you can is to pull the dishwasher out from under the cabinets and lay it down so the bottom is exposed. This would make the process a little smoother.
