My white coffee cups have developed black marks inside. I thought it was the glaze coming off th cups, but have discovered it is a black build up that can be washed off with comet and elbow greese. What is causing the black residue? Otherwise the dishwasher cleans great! Thanks, Pam

Dennis, Im assuming your model number starts with 665. This model had a service flash on it regarding the upper spray arm. The upper spray arm has been redesigned for better performance. Part number 8269022. This could be covered by Sears if you mention the service flash, 22-714. Other issues that can lead to this problem are; water hardness, if your water is over 7 grains of hardness, this could to this film on the glasses. Try pouring 1/4 cup of Glass Majic into the bottom of the dishwasher. Also run one cup of white vinegar to clean the dishwasher. Make sure the water temp. entering the dishwasher is 120 min. to 150 degrees. Catriver..post back.

the problem is hard water and there is a new product out called the dishwasher filtration system. it actually filters the water going into your dishwasher and leaves your dishes spot free. after the first load i was amazed that the white film was gone and my dishes were sparkling. you can get it at www.dishwasherfilter.com.

SOURCE: dishwasher dishes not clean

first of all to remove residues from your d/w...what will work to remove the scale and soap residues is called "d/w magic". it comes in a plastic square bottle and you can get it at any grocery store, lowes, or sears.
you just remove the cap, put in the top rack and run a full cycle with the water heat boost option and it will clean out almost any residue from your unit. if it is really bad you may need to repeat this 2 times.

then in the future use dry powder soap, not tablets, fill both cups only about half full, use the normal cycle with the water heat option. also make sure the rinse dispenser is full with jet dry or similar product. then you should not get the residues returning.

after you have tried this then you should brush off any food particles before putting the dishes into the unit. do not assume the d/w will "chop" up any food left on the dishes. they are designed to chop up soft food items, but they also will get plugged at the same time. so its best to just brush the dishes off first.

next is if you still have washing problems, then make sure the unit is filling up with enough water. after you start a cycle, let the unit run for about 2 minutes, open the door and see if the water is just below the level of the heating element. thats how much water they need to circulate properly.

i will reply back if you want to know more.
good luck tom

is that a glass? can't tell. is there water curculating to the top rack? if not you probably have a bad chopper
