   Drain hose run.

   Is there anything unusual about the route of the drain hose?  Long horizontal b/4 going up and back down to the drain connection at the sink?   Or no run up high b/4 connecting to the drain?

   Like a sump pump, any water not evacuated in the line runs back.

   Vision.

   This may be inappropriate, so I saying up front, it is just some lighted hearted fun.

   I'm picturing a dishwasher setting on a porch beside a washing machine and a old wooden chair.

   Wouldn't be that unussual in eastern KY.

   Just trying to figure out how mosquitoes ar getting a dishwasher :)

   Would that be your neck of the woods?

   or are you dissing the other end of the state?

   I didn't think at the time, but I'm sure it sounds sensible that these units have check valves rather than relying on a high loop.  And if it's damaged or stuck-most probably could lead to a swamp.

   But, mosquito's breeding?   That sounds odd-fruitflies epidemic sure, around the compost pail-but mosquito's..................

   Proves you never have heard it all.

   They could try aerial spraying for mosquito abatement.

   Yeah, how long is the drain hose, and how is it routed?  If there's no high loop then what you could have is water flowing back from the sink drain into the DW.

   Check Valve

   The last dishwasher I worked on, a GE, had a little rubber flapper/check valve at the outlet of the pump where the drain hose attaches.  I won't guarantee that Whirlpool does the same, but I would look for such a valve and see if it is crudded up, worn, or damaged.
