Washing less effectively over time

As my dishwasher has aged (4 years ish) the dishes are getting less and less clean. Glasses frequently have white film left in bottom. Mugs have coffee stains in bottom. I have to make sure everything is rinsed before I run the machine and even then its not so great.

I did spend about 20 min picking crud out of the bottom the other day and it got marginally better - thoughts?

I just had my Maytag dishwasher serviced. It was getting less and less efficient over time. The items on the top rack weren't even getting clean. The repairman showed me the problem: the water was not spraying very well at all.

There's a round water filter at the bottom, underneath the spray arm. It's a hard plastic mesh ring, maybe eight inches across and four inches high. This ring was completely covered in garbage. Gunk, pieces of cellophane, you name it. No way water could get through it. I was amazed to see how clogged it was.

He took out the ring, scrubbed in clean, and put it back. The water now sprays like there's no tomorrow. Practically like new.

The problem is the mesh ring getting clogged. Clean this out should fix problem. Also running hot cycles is good maintenance. Hot cycle is turning on hot settings and run 1/4 to 1/2 cup of vinegar in the machine while empty it will clean all the soap sludge build up and some food it dissolves residues and gets rid of smells in the machine. Run this for sure every six months. Do this also in your washing machines for clothes as well. Should run great for years to come. Hope this helps

We had an ongoing battle with white film on glasses and dishes, inside...

<p>If your <b>dishwasher does not seem to be cleaning well</b> anymore and you are getting<b> residue and film left on your dishes</b> then you need to read this.<br /> <p><br /> <br /> <p>Since July of 2010 the US Government has mandated that <b>dishwasher detergents</b> contain no more then 0.05% phosphates in them. The Detergents before this had contained up to 8.7% phosphates. The restrictions were for 16 states but many companies then dropped the phosphates from detergents to all states...<br /> <p><br /> <br /> <p>Now if you are having the <b>scum, film, and white residue problems</b> in your <b>dishwasher, </b>there is hope.<br /> <p><span>There is a product that you can buy that will compensate for what the makers of the </span><b>dishwasher detergents</b><span> have left out. This product as commonly know as </span><b>TSP</b><span> or </span>(<b>Trisodium Phosphate</b>).<br /> <p>By adding this to your dishwasher, you can manually add back the phosphates to your dishwasher and enhance the cleaning process.<br /> <p><br /> <br /> <p>Now the nest question...how much TSP do I add to the dishwasher?<br /> <p><br /> <br /> <p>For many dishwashers, waters, and for normal loads you will find that a tablespoon or two is all that you will need. For very hard to clean dishes and for some types of water you may need to add up to a 1/3 cup of TSP. <br /> <p><br /> <br /> <p>If you are having problems with your <b>dishes not getting clean</b>, a <b>black or scum film</b>, or <b>white residue</b> being left on your dishes at the end of the cycle, then I would start with a tablespoon or two and then adjust from there. Figure out how much you need to add to you dishwasher to make your <b>dishwasher detergent </b>work correctly for you again.<br /> <p><br /> <br /> <p>To best part is that you can have <b>clean dishes </b>coming from your dishwasher again!!<br /> <p><br /> <br />

Glasses have a white, chalky film around the top of glasses

This due in part with the government mandate to remove phosphates from detergent.
Several things can be done to improve the clean appearance of your dishes.
1. Start a wash cycle with no dishes and no soap. Once the wash cycle has stated and water is circulating,open the door and pour in one quart of white vinegar and resume the wash cycle.
2. Use a detergent named FINISH.
3. Use only the recommended amount of detergent.
4. Periodically use a product named LemiShine.
Taking these steps will improve the quality and appearance of the dishes.
On a final note: too hot water temperature can cause etching in glasses and only a lower water temp will prevent new glasses from etching.

When the wash cycle is done, the dishes are wet

It seems that the newer dishwashers are worse at drying dishes than their tupperware melting predecessors were. They have all been tuned down, and do dry less. The only thing that you can do is to set your machine for the hottest wash, power dry and use a rinse agent that provides a sheeting action. Some folks use white vinegar as a supplement to their rinse aid, which has the added bonus of killing mold. Water also stays attached if the water has laid down minerals as noted by cloudy glassware. If this is the case, a dishwasher filter (dishwasherfilter.com, $70) might help. We try to wash hot, with a power dry and use a rinse aid/vinegar. Then, when the cycle is complete, but the dishes are still hot, we open the dishwasher, and "jiggle" the racks to get the excess water off of the glasses, and leave the dishwasher open about 2" at the top, so the dishes will continue to air dry. This has been an effective method for us.

Hi, We have a new whirlpool dishwasher type no. 575-0. GU2275X TVQO. We have not been able to get clean dishes since purchase. Water is hot, everything seems to be operating smoothly. Use the...

I think I can help. We have the same dishwasher and we have very hard water. The dry powder detergents don't work well. We have found Cascade All in One Gel detergent works best and we use only a little; don't go beyond the first mark in the detergent dispenser, regardless what the instructions say. We have found using more of any detergent makes white film. Don't fill up the pre-wash side either. The Cascade All in One Gel does both at one time, so no need to put some in the pre-wash side. Also keep Jet Dry in the rinse dispenser and make sure it is set up higher, turn the arrow to 4. Try that and move up if needed. Next, we put half a cup of white vinegar in the dishwasher, just pour it in the bottom each time, right before we wash the dishes. This works GREAT! We used the white vinegar in on our former dishwasher of 9 years and never had any trouble with any film buildup. The vinegar cuts all the film and makes glasses look terrific.

If you are still are having trouble, cut out the Heated Dry at then end. The heat can cake hard water on your dishes. It may not dry the dishes as well, but it seems to stop any buildup. Using the vinegar though, we use the Heated Dry and still have no film buildup. So for us, we use a small amount of Cascade All in One Gel detergent (buy this basic gel, no added anything), 1/2 cup white vinegar poured in the bottom and Jet Dry in the rinse dispenser. We always have sparkling clean dishes with no hard water buildup. If you don't have real hard water, but just a little hard water, you might try decreasing the white vinegar to 1/4 cup and increase it if you start seeing the white film build back up. Also don't overload the dishwasher. Make sure there is space in-between each dish and have all plates face toward the center.

Make sure you turn your sink faucet on to as hot as you can get it and run the water until it is hot, then turn off the faucet and turn on the dishwasher. This helps to keep the dishwasher from running longer, which would mean more hard water swishing around longer if you don't heat the water, and you know what that means, plus the heating element has to work harder to get the temp up and that makes it burn out quicker. Once a month check your jet sprays, that turn around in your dishwasher, because the little holes can stop up with hard water gunk and this will cause film on your dishes to build up. Take a toothpick and crush the gunk in any holes and make it go out of the holes. Hope this helps you!

Dishes not getting clean

brittgee, there has been a number of service flashes on this model. One that has to do with the upper spray arm assy. Complaint is poor washability; gritty glasses, food redeposited on glasses, especially in the corners. They redesigned the upper spray arm to improve water spray to all corners of the upper rack. The new part number is 8269022. They also redesigned the third level spinner for more consistant rotation and better washability. This was also under a service flash. Part number.8193768. Other reasons for poor wash would be; low water temperature, rinse aid disp. not working, loading etc. Catriver...post back.

Kenmore dishwasher 15899100

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.
