MyWhirlpool model number DU920PFGG2, serial number FJ3453664 is leaving a white chalky film on my dishes. The rinse cycle sounds like it should be working but it isn't rinsing well. We are also using jet dry but that isn't helping. Any ideas? Thanks

SOURCE: white film on dishes

Experience : 30 years in dish washing as a professional instructing hospitals and restaurants.
It is not necesaasry to cover the heating element as long as sufficient water is present so as to not STARVE the water pump.
Listen to the sound of water serging with the machien running. If it is contant you have enough water if the sound comes and goes then the pump is serging . either lyou have a low water level or CLOGGED strainer in the bottom of the machine (inside).

you might also open the door real fast during the wash and check for water splashing and flows---- you might get wet but this way works .(wear protective eye shields)

water levels can be raised by BENDING the tab on the bottom of the float which controls water level...much like a toilet tank float.
Also finally if soap levels are too high the soap will not rinse off regardless of the amount of "rinse fluid you use.

SOURCE: Soap film on dishes

Rodney B if you are sure that the white film is detergent and not hard water deposits, then look at how you are using the detergent. When you watch the TV ads for dw detergents, they are showing baked on/extemely dirty dishes being put in the dishwasher and coming out clean. Well they do this as the dw detergent is designed to break down protein based food products. Fats, oils, and such. If you are prewashing your dishes before putting them in the dishwasher, then there is nothing for the detergent to attack and attach to, so it ends up staying in the dishwasher. If you are going to rinse your dishes, then you need only 1 tablespoon of detergent. Dishwashers are designed to clean using 4 parameters, hot water of 130 degrees, water, detergent,& pressure of the water jets. That is how they clean dishes. Now if this is hard water deposits, switching to an enviromently friendly detergent which is high is Citric Acid (What gives Tang drink its tartness) this will reduce this issue. Hope this helps

Hard water "filming" is caused primarily by the higher deposit content in hard water clogging up the jets and nozzles. Therefore, there is not the normal pressure for washing or rinsing. This can be eliminated by turning on the dishwasher, while it is empty, and waiting for it to fill and go into it's wash cycle. They open the door and add 3 cups of white vinegar and finish running through the cycle. This will open the nozzles and jets to their full capacity. After that, use a rinse aid for sure.

SOURCE: dishwasher leaves heavy residue

Check your spray arms and look for the holes that water sprays through .Are there any clogged holes.Clean them if you see they are clogged.If not clogged up,your heater is not working ,check for voltage > 120V. If you have 120V. Check water level,it should be just under the heater. PLEASE LEAVE A RATING !!!!!

SOURCE: chalky film on dishes

check to make sure you are using the correct detergent & amount for your new washer - depending on the hardness of your water.
Clean the air gap.
Your problem could be one of two things. 1) Hard water. Outside of getting a water softener there really isn't much of a cure for that one. If you are unsure if you have hard water or not, simply take a sample to a local fish store and most of them will test it for free, or call your city's water department and ask. 2) Most likely though it is because you are using too much detergent. How often have you said to yourself, gee there's a lasagna pan in there, better fill up the little dispenser AND give it an extra big 'ole squirt just cuz it's really greasy? Try this, place a coffee cup standing upright on the bottom rack of your empty dishwasher. Fill the cup up to the brim with vinegar and run it through a cycle. This should clean out any residue that is in there currently. Then, the next time you do the dishes use HALF the detergent you normally use. See if that helps. Good luck!

The problem is hard water. There is a new product out called the dishwasher filtration system. It filters the water before it enters your dishwasher. It works amazing and has a money back guarantee. You will love the way your dishes look after the first load. It is also very affordable (like 70 bucks). Go to www.dishwasherfilter.com to find out more info.

Glass and cutlery has a chalky white film after washing


The problem is most likely that there is still water residue at the bottom of your machine. If the machine is not fully drained it picks up some of the residue and sprays that onto the dishes during the final rinse, leaving an unhealthy and unsightly film on everything.
Remove the bottom strainers plates and make sure that the outlet pipe is not kinked, that there is nothing obstructing the pipe or the pump or selector valve. If possible back flush through the outlet pipe and try draining the machine again before using it again.

The white film that you are talking about could be two things. First is the quality of your water, having sediments either through the water system or from the water heater because the water that goes into the dishwasher is taken from the hot water supply. Second is the build up of soap residue and even with a rinse product it is not able to remove it. A simple remedy is to due a wash and rinse cycle without dishes and put vinegar in the dishwasher about a cup full (8 oz) and see if that will help. If not I would check the water and going in and out of your water heater. Good Luck

White film 0n dishes and especially glasses


It is a drain problem, check the drain hose and drain pump.There should be some problem with the drain being blocked that is eventually pushing the dirt water back and front.Thereby leaving detergent and dirt back in the dishwasher.
Provide me the model number and i can help you out with some internal diagrams in case you don't find the drain pump.
Good luck and please do post for further doubts arising on this solution.
