whirlpool dw WDT750SAHZ0 - how do i run a diagnostic?

[wendyvt]

Hi! newbie here! i've got a whirlpool dw WDT750SAHZ0 that has worked fine for over 6 months of daily use -- i bought it from a "scratch-n-dent" store. just yesterday, dw lights showed "clean."  i oped the dw, and the dishes were all dirty. tried to run it again, then realized there's no water getting into dw. i checked the float, and i hear a faint "click," so i'm thinking that part is ok. i put the dw into a cycle mode, and i do hear a motor which i'm assuming would be a water pump running, but inside is dry as a bone when i open it up. now i'm assuming it's the water inlet valve. (that being said, i do have a mouse problem -- little bugger just chewed up my printer power chord. could mickey have eaten some of the wiring on the water inlet valve?) sidenote: i did check the water supply and it's on, as always -- it's just saddled into my hot water supply for my kitchen sink so it's can't be off unless i turn it off at the source. 

since we live way out in appalachia, finding an appliance repairman will be an exercise in extreme patience, and i'd like to be able to at least give him a hint before he drives all the way out here, only to find he doesn't have my particular water inlet valve. i was wanting to run a diagnostic test. unfortunately, there is no instruction on how to do so with this model. the only instructions i've found say to hit the "rinse" cycle. there is no "rinse" cycle on this model. it's got "sensor/heavy/normal/1-hour wash/soak & clean." there's no display either. on the other hand, am i just "pissin' up a drain pipe" even bothering with a whirlpool self-diagnostic? is it of any value?

oh, did i mention that being the scaredy cat that i am, in order to block the mouse, i sprayed copious amounts of foam insulation into every crevice i could find, including the sides of the dw kickplate? 

thanks in advance!

Usually on the back of the toeplate there is envelope with the tech sheet. This will have procedures and error codes you need to troubleshoot. While your getting the tech sheet look for obvious damage by the mouse. Could be as easy as chewed wires.

thx! i've been looking for the tech sheet bc i'm pretty sure i took it off when installing and just threw it in a drawer!

Hope you can find it. When you unfold to be 24" by 24". Lots of information.
