Dishwasher that would only fill with water sometimes.

We took the hoses off, cleaned all the hard water deposits and screens. The water would fill once but not a second time. We ordered the water valve and valve switch. We put the new water valve on and "miracle" it worked perfectly. We didn't need to replace switch. Let me tell you this is one happy housewife now. Ordering the parts on-line was very easy and they arrived as they said they would. Thanks for the great service.
