Jenn Air dishwasher not circulating water properly
Here is what the User Guide has to say...


  Troubleshooting
  
  Spots and stains on dishes
  
  
  Spotting and filming on dishes
  
  
  Is your water hard, or is there a high mineral content in your water?
  Conditioning the final rinse water with a liquid rinse aid  helps
  eliminate spotting and filming. Keep the rinse aid  dispenser filled.
  Always use a high-temp option.  Is the water temperature too low? For
  best dishwashing results,  water should be 120°F (49°C) as it enters
  the dishwasher. Did you use the correct amount of effective detergent?
  Use  recommended dishwasher detergents only. Do not use less  than 1
  tbs (15 g) per load. Detergent must be fresh to be  effective. Heavy
  soil and/or hard water generally require extra  detergent.
  
  
  Silica film or etching (silica film is a milky, rainbow-colored deposit; etching is a cloudy film)
  
  
  Sometimes there is a water/chemical reaction with certain  types of
  glassware. This is usually caused by some  combination of soft or
  softened water, alkaline washing  solutions, insufficient rinsing,
  overloading the dishwasher, and  the heat of drying. It might not be
  possible to avoid the  problem, except by hand washing.  To slow this
  process use a minimum amount of detergent but  not less than 1 tbs (15
  g) per load. Use a liquid rinse aid and  underload the dishwasher to
  allow thorough rinsing. Silica film  and etching are permanent and
  cannot be removed. 
  
  
  White spots on cookware with nonstick finish
  
  
  Has the dishwasher detergent removed cookware seasoning?  Reseason
  cookware after washing it in the dishwasher.
  
  
  Brown stains on dishes and dishwasher interior
  
  
  Does your water have high iron content? Rewash dishes using  1-3 tsp
  (5-15 mL) of citric acid crystals added to the main wash  section of
  the detergent dispenser. Do not use detergent.  Follow with a Normal
  wash cycle with detergent. If treatment is  needed more often than
  every other month, the installation of  an iron removal unit is
  recommended.
  
  
  Black or gray marks on dishes
  
  
  Are aluminum items rubbing dishes during washing?  Disposable aluminum
  items can break down in the dishwasher  and cause marking. Hand wash
  these items. Remove  aluminum markings by using a mild abrasive
  cleaner.
  
  
  Orange stains on plastic dishes or dishwasher interior
  
  
  Are large amounts of tomato-based foods on dishes placed in  the
  dishwasher? It may be necessary to use a stain removal  product to
  remove stains from your dishwasher. Stains will not  affect dishwasher
  performance
  
  Dishes are not completely clean
  
  
  Food soil left on the dishes
  
  
  Is the dishwasher loaded correctly?  Can the spray arm rotate freely?
  Did you choose the cycle that describes the most difficult soil in 
  your dishwasher? If you have some items with heavier soils,  use a
  heavier cycle. Did you use the correct amount of fresh detergent? Use 
  recommended dishwasher detergents only. Do not use less  than 1 tbs
  (15 g) per load. Detergent must be fresh to be  effective. Heavy soil
  and/or hard water generally require extra  detergent. Is detergent
  still in the detergent cup? Use fresh detergent only.  Do not block
  the detergent dispenser. Is the water temperature too low? For best
  dishwashing results,  water should be 120°F (49°C) as it enters the
  dishwasher.
  
  Dish Washer Care
  
  Cleaning the Dishwasher
  
  Clean the exterior of the dishwasher with a soft, damp cloth and 
  mild detergent. If your dishwasher has a stainless steel exterior, a 
  stainless steel cleaner is recommended.
  
  NOTE: Do not clean the dishwasher interior until it has cooled.
  
  Clean the interior of the dishwasher, with a paste of powdered 
  dishwasher detergent and water or use liquid dishwasher detergent 
  on a damp sponge to clean the cooled-down interior. 
  A white vinegar rinse may remove white spots and film. Vinegar is 
  an acid, and using it too often could damage your dishwasher.
  Put 2 cups (500 mL) white vinegar in a glass or dishwasher-safe 
  measuring cup on the bottom rack. Run the dishwasher through a 
  complete washing cycle using an air-dry or an energy-saving dry 
  option. Do not use detergent. Vinegar will mix with the wash water
  
  Periodically clean the coarse 
  filter cup located on the floor of 
  the dishwasher drawer. Remove 
  collected particles from the 
  coarse filter cup.
  
  IMPORTANT: Do not start the 
  dishwasher until the coarse filter 
  cup is securely in place and 
  flush with the coarse filter plate. 
  Doing so may damage the 
  dishwasher motor and/or spray 
  arm. 
  
  Cleaning the Coarse Filter Cup
  
  
  Pull drawer out to its full extension. Remove rack inserts from 
  rack and set aside.
  To remove the coarse filter cup, unscrew the small cap, turning 
  in a counterclockwise motion. Lift and remove the coarse filter 
  cup out of the drawer.
  Empty the cup of hard objects and food soil. Rinse cup under 
  hot water.
  Place the coarse filter cup back into the coarse filter plate and 
  tighten the cap, turning in a clockwise motion. Make sure the 
  coarse filter cup is flush with the coarse filter plate.
  Replace the rack inserts.
  Make sure spray arm rotates freely
  
  
  If you have a drain air gap, 
  check and clean it if the 
  dishwasher isn't draining 
  well.
