My 6 yr old Kitchen Aid dishwasher is leaving food residue
My 6 yr old Kitchen Aid dishwasher (model KUDR01TJWH is leaving granular food residue on inside of coffee cups on top rack at end of cycle. I have trouble shooted the following: spray arms clear of any obstruction; water temperate fine, input valve/solenoid appear to be ok, fine debris screen is clean. Any idea of the source of the problem??
Re: My 6 yr old Kitchen Aid dishwasher is leaving food...
After checking all sprayer arms for clearance, and checking heating element and discharge pump, the problem was solved by replacing the small sprayer arm at the top of the washer. This small arm had popped off some time ago - obviously the water pressure was excessive for the small and unimpressive fastener. Luckily we had saved this piece, which I refastened with a strong aluminum non-corroding small bolt. Presto - now the water distribution is back to design specs, with sufficient water coming out under pressure from the mid level arm. Lesson: always look for the simplest cause first with the simplest solution. TCA

Make your dishwasher more effective with these quick tips:
1. Check the sprayer arm. When I opened the dishwasher door during a wash cycle, I learned that some of my utensils are too tall, and they blocked the sprayer arm from rotating. Problem solved! Also look at the holes on the sprayer arm to make sure they are not clogged. Use a toothpick if you need to dislodge anything.
2. Check the drain. Look inside the bottom of the dishwasher and remove any food or objects from the filter. Run the garbage disposal to clear it out before turning on the dishwasher since they share the same drain.
3. Don't overuse detergent. It's a mistake to assume you should always fill up the detergent cup. Check the manual and your detergent. On mine, filling it to the first line (about a third) is enough. Too much detergent can leave residue and etch your glasses.
4. Check your water temperature. If it takes a long time for the hot water to reach your kitchen sink, that means the dishwasher isn't getting enough hot water at the beginning either, and that makes it harder to wash away the food particles and grease. If you need to, turn on the dishwasher after you've used hot water at the kitchen sink.
5. Clean the inside of your dishwasher. Grease, detergent residue, and calcium deposits build up inside your dishwasher. You can use vinegar to wash them away. On a regular basis (every few months or so), run a wash cycle while your dishwasher is empty. Don't use detergent, but turn on the dishwasher and let it run for a few minutes until water starts to fill up the bottom. Then add one or two cups of white vinegar to the water and let it finish the cycle.
Sometimes using a dishwasher is an experiment in finding the right combination for hard or soft water, the detergent, and a rinse aid.
Best of luck
I have had this problem. Mine didn't work for over a week and by the time the repair man came over to 'replace the board' it suddenly worked. The guy told me that if you use ANY type of liquid dishwashing soap (for your sink) and any residue/bubble is on the dishes, it can cause your dishwasher to break. I have no idea why but I've been really careful to make sure I wasn't using dish soap prior to putting them in the washer. I've had 3 service calls on this dishwasher since I purchased it 3 years ago. I'm having similar service issues with my Kitchen Aid Fridge. And of course no help from Kitchen Aid.
Hard water stains are easily taken care of with the help of vinegar. Add 1/4 vinegar to the cycle when you start it and it will help to remove spots and cloudiness.
As for food residue you might check your filters and water pressure.
The problem is hard water. Go to www.dishwasherfilter.com. They have a new product out that solves this problem once and for all. It filters the water entering your dishwasher and removes the hard minerals that cause these spots. Very affordable and guaranteed to leave your dishes looking amazing every time.
Although I previously posted with the same problem of a film on the dishes after cleaning, I did find a section in the owner's manual which solved my problem. Lift up the rinse aid cap on the inside door - the factory setting is on "4". The rinse aid works in conjunction with your local water, which has variations in it's hardness or softness. When your dishes are streaky, lower the rinse aid setting to 1 or 2. If your dishes are spotted, raise the rinse aid setting higher.
