Dishwasher not cleaning food is still on dishes


There are many probable causes of failure .

A dishwasher's water inlet valve is its most common part to fail. When your dishes are not being fully cleaned, quite often a faulty water inlet valve is to blame. Test your dishwasher's water inlet valve, and if it is no longer functioning as it should, you will have to replace it.

Water temperature is a key element in achieving clean dishes. A dishwasher's heating element is not designed to heat the water that enters it. Rather, the heating element is designed to maintain the heat of the water that enters the dishwasher. Its a good idea to run the hot water in your sink for a couple of minutes before you run the dishwasher. Just to make sure the water is nice and hot before it enters the dishwasher. If the water is unable to stay hot, it can adversely affect your dishwasher's cleaning ability.


There is a filter in your dishwasher. Its function is to keep large particles of food and foreign objects away from the pump. Many of the newly-manufactured dishwashers have self-cleaning filters, and routine cleaning isn't a concern. However, some other dishwashers need to have the filter removed and cleaned regularly. If the filter or grate is clogged or blocked with debris, it may interfere with the normal functioning of your dishwasher

Dishwasher never cleans, glasses gritty dirty -- Bosch terrible s


you obviously need to check and make sure that you've cleaned your filter system. it needs to be cleaned every couple of months. and also make sure that your washing fans, the ones that spray water, aren't clogged. they need to be washed out and de-clogged regularly as well... i had this same problem.. but it worked fine once i cleaned the system.

Dishes aren't clean. i have run vingegar and CR through the cycle but dishes and glasses still have a film.


The most common cause of film left behind is a broken heating element.

The heating element is not only used during the dry cycle, but also to raise the water temp. during the main wash cycle to activate the dishwasher detergent. Fixing the heating element should "clear" this problem right up!

Model # dwu7702aae has heat delay light coming on during cycle. Why?


Heater is used to both heat water during clean cycle and dry dishes after wash cycle. Most washers have either a separate switch for Heat or Dry for optional use, or some have the water heat and dish dry options built into cycle set options.

You can save money by turning off the Dish Dry option since it is a very in-efficient way to dry dishes. Instead, open the wishwasher door after washing cycle completes, just enough so fresh air can get into, and humid air can escape, dishwasher.

Water Heat option is only needed for dried food on dishes, and is never needed if dishes are either rised off before putting them in the dishwasher, or rinsed off inside the dishwaser with a Rinse cycle, if they are to stand for a time waiting for a full dishwasher for wash.

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.
