I want you to get a laugh out of this - as well as your bonus of course.
My brother & I took the panel off the bottom front of the DW to see if there was water in the base pan - there wasn't.
I started the DW (hasn't been run since it stopped working in early June) - we could hear the pump run then it called for water and my brother said it sounded like the water line was turned off. I said no, we hadn't turned it off. I showed him where the valve is and we found it was indeed turned off.
Mr. Fixit (my husband) had turned it off while working on something else under the kitchen sink and completely forgot he'd turned it off. Wa La! My DW is running like a top.
Fortunately for Mr. Fixit, he's a superb cook, so we'll keep him around :-)
Thank you for sending us down the rabbit trail that got the problem fixed. I'm sure the advice you gave was completely appropriate for the situation in the absence of the "stupid factor."
