DISHWASHER NOT CLEANING WELL??
Here are 5 common reasons why not.
Here are Improper Water Temperature
I can tell you from personal experience that water temperature has a direct impact on how well your family's dishwasher operates. If the water entering your dishwasher is not hot enough, your dishes are likely to come out coated with grease and dish detergent residue. As such, you will want to make sure that the temperature of the water inside your dishwasher is somewhere between the range of 120 degrees Fahrenheit and 140 degrees Fahrenheit. If it's not it could be a faulty heating element.
Dirty Pump
Based on my experience, a dirty dishwasher pump will also cause your dishwasher to produce less than stellar results. Therefore, you may want to consider cleaning your dishwasher's pump every six months. In many instances, it is an easy task to complete. In order to clean your dishwasher's pump, you'll most likely have to remove the dishwasher's spray arms. Once the spray arms are removed, you'll want to clean and inspect the pump's impellers, blades and pump guard. I should also mention that there are appliance companies that sell dishwasher pump repair kits should you notice that a part needs to be replaced. A basic dishwasher pump repair kit will tend to cost you $20 to $60 depending on your dishwasher's unique needs.
Dirty Spray Arm
Dirty spray arms may also be to blame. After all, if the spray arms' holes are clogged, the hot water won't be able to reach the dishes properly. A dishwasher's spray arms are very simple to clean. In order to clean them, you will need an old toothbrush and a bread twist tie that has been stripped of its paper. Use the toothbrush's bristles and the wire from the bread twist tie to unclog all the holes.
Broken Dish Detergent Dispenser
A broken dish detergent dispenser is another likely culprit when it comes to dish cleanliness problems. Sometimes the dish detergent dispenser's door will not open or shut properly, which prevents the dishes from getting nice and soapy. The good news is that most dish detergent dispenser problems may be solved relatively inexpensively. The cost of a replacement dish detergent dispenser will vary based on the make and model of your dishwasher. There are also instructional videos online that will help you with the installation of your dishwasher's new detergent dispenser.
Dirty Filter
A filter has an impact on a dishwasher's effectiveness as well. Hence, you will want to inspect your dishwasher's filter for obstructions. The location and type of filter will vary based on your dishwasher's make and model. I would recommend that you check out your dishwasher's operator's manual. It should contain instructions on how to clean your particular unit's filter as well as where you can order a replacement part if need be.

Supply water temperature should be above 120 degrees F for effective cleaning. Run hot water from your kitchen sink (your dishwasher should be tapped off the hot water line near your sink faucet) right before you start a dishwashing cycle to make sure it's as hot as it can be when the dishwasher begins filling. Also, during the wash cycle the heating elements at the bottom of the tub may turn on and warm the water further even if you select a "No Heat Dry" option causing a noticeable shot of steam to escape if you open the door during a cycle.
Note: I recently had a problem with our dishwasher (Frigidaire FDB834RFS0) causing dishes to come out dirty and the detergent dispenser to be left with undissolved detergent. Our problem happened to be caused by a partially clogged strainer in the water supply valve. (I would imagine Whirlpool most likely has some kind of filter/strainer in its water valve as well.) When the supply valve was commanded to open for some time, I noticed the water level in the tub would barely be visible below the lower spray arm. After cleaning out the strainer (required removing and disassembling the water supply valve) the water level was noticeably higher -- almost at the bottom of the float or about an inch below the heating elements. Our dishes and the detergent dispenser are now clean.
If your water supply is ok, I would next check to make sure your spray arms do not have any plugged holes and that they rotate freely. Also, use a good quality detergent and a rinse aid. We prefer liquid Cascade and Jet Dry. We have had problems with old, stale, or really thick liquid detergents and by getting a fresh jug have solved the dirty dish dilemma.
Make sure to clean out the filter basket at the bottom of the basin below the lower spray arm occasionally as it can clog and cause the pump to starve due to lack of water. If the pump can't get a supply of water to pump to the spray arms and nozzles, your dishes will not get sprayed evenly and you will end up with them being poorly cleaned.
Hope this helps you out...good luck!

hello,

If your dishes are coming out of the dishwasher covered by a removable dirty film, your water may not be hot enough, or you could be using an inferior brand of automatic dishwashing detergent. If you have tested your hot water and find it is between 140 degrees and 160 degrees Fahrenheit, consider how long it takes for the hot water to reach the dirty dishes in the dishwasher. If the hot water has to travel a long distance to reach the dishwasher, chances are the water filling the dishwasher starts out cold. To alleviate this problem, run the hot water nearest to your dishwasher until the water coming out is hot. This will guarantee the water filling the dishwasher is as hot as it should be to properly clean dirty dishes.

To remove this type of film from dirty dishes, after running the dishes through a basic rinse cycle, set a bowl filled with a cup or two of white vinegar on the lowest rack of the dishwasher. Remove any metal pans or utensils, and with the vinegar on the bottom rack, wash the dishes as usual. Dirty dishes that were once covered in film should come out squeaky clean

thanks.

If the glasses are spotty from hard water try a rinse aid like Jet Dry. If they are actually dirty, depending on the brand of DW you may need to rinse them better before putting them in the DW. Not all brands are cerated equally, some do work better then others

Check that both spray bars are turning. They can both be easily removed.

Once removed, make sure they are not clogged with stuff to prevent them from turning.

I assume you can hear water spraying around inside when it's washing, and that the dishes do get wet, and water does get hot.

Soap dispenser requires water hitting on it to open.

Is the hot water faucet under the sink open all the way?

If your dishes or glassware appear filmy or spotted following a complete wash cycle, adjusting the amount or type of detergent you're using and adjusting your hot water heater's water temperature may solve the problem. But before you do either of these, put a rinse additive (such as Jet-Dry) in the rinse dispenser to improve the sheeting action of the water. First you'll have to determine whether the film is removable or permanently etched. To do this, soak a glass in undiluted white vinegar for about 15 minutes. Or, you can wash the glass with warm water and concentrated dishwasher detergent or use a high-phosphate detergent (such as Glass Magic) according to label directions. If film comes off, it is probably caused by hard water minerals, improper amounts of detergent, or unsuitable water temperature. See "Doesn't wash well," above. Permanent etching is often caused by a combination of soft water and excessive heat or detergent. If glassware is permanently etched, there isn't anything you can do to make it clear again. But you can avoid future etching by taking these steps: 1) Be sure hot water entering the dishwasher is no hotter than 140 degrees F. Don't use extra hot settings, such as "Power Scrub" and use "Energy Saver" dry cycle. 2) Adjust detergent amount. 3) Don't pre-rinse your dishes before loading them in the dishwasher. Food particles on the dishes actually help the detergent and drying agents clean better.
