tee hee!  Because I am so freaking awesome I just fixed our diswasher myself and saved us about $120.00.  It wasn't filling with water at all.  Everything else was working, just no water.  So, I called around and got told the fix was the inlet valve, the stupid man at the shop didn't think I could fix it.  I fix everything around here.  I am the plumber.  So, I looked it up online and the instructions said it was an easy fix that should take less than an hour.  I called the shop guy back and told him to order the part for $35.00.  He had suggested I call a diswasher repair man and the rates go as follow: $60.00 
just to come out, $60.00/hr, plus the cost of the part $35.00.  It was so easy to fix.  The hardest part was waiting the two days for the part.  So, I got it changed out and water 
still wasn't getting in the diswasher.  So, I looked online again and decided to check the float valve.  It was soooo dirty, I cleaned it out and it started working.  Now, the question is, did I waste $35.00 on a new inlet valve?  Or were both things stopping my dishwasher from filling with water, I guess we'll never know, but, I feel pretty awesome that I just saved us $120.00 from the stupid dishwasher repair man.  Pfff, who needs a dishwasher repair man when I'm around???  :)
