Dishes are still dirty after washing sandlike material on outside of wine glasses as well as water spots I rinse all dishes before they go in.

I have spent a 50 year career in catering using dishwashers and seen all the damage that can cause. Etching is caused by using too much detergent. They tend to be based on Caustic Potash. Use as little as you can get away with. Rinse aids don't normally cause spotting, but having the water too hot can. If you are having problems, change the detergents and lower the temperature. You can also try Calgon water softener, but only a little. Also make sure filters are clean and run a liming solution through the machine once every 6 month. Before I retired, I was manager of a Toronto Airport business class lounge, and we washed thousands of plates and glasses a day 5:00am to 11:30pm. We descaled every week.

may need some rinse agent. verify the liquid level in the rinse agent bottle.

Hello.
If you've just installed a Whirlpool Gold dishwasher, consider yourself truly liberated from the drudgery of standing at the sink washing plate after plate and saucepan after saucepan. You'll find it much easier to keep the kitchen clean as your dirty dishes are hidden away in your new appliance and all you have to do is wipe down the counter tops and switch the dishwasher on when it's full. However, to get the maximum benefit from your new piece of equipment, it's important to use it correctly.

Instructions
MATERIALS NEEDED WHEN OPERATING.
* Dishwasher detergent
* Dishwasher rinse aid
Preparation of Dishes
1 Scrape leftover food off the dishes and make sure no other hard objects such as small bones or toothpicks remain on them.
2 Remove sticky labels from any newly bought food containers you are washing for the first time.
3 Make sure any leftover coffee, tea, soda or wine has been poured out of cups, mugs and glasses.
Loading the Dishwasher
1 Place cups, mugs and glasses in the top rack with the open ends pointing downwards. Cups and mugs should go along the left and right outside edges, with glasses beside them. Position small plates and saucers in holders along the center of the rack running from back to front.
2 Place larger plates and bowls in the bottom rack, which is also where casserole dishes and saucepans should be washed. Avoid overlapping bowls and plates, because it is important every surface is open to the water directed around the dishwasher's interior during the program.
3 Create a flat surface on which to lay saucepans and larger dishes by collapsing some of the plate holders on the bottom rack, if your model dishwasher allows. Lay them open-end down to allow the water to be directed around their interiors.
4 Position dirty saucepans at the rear of the bottom rack with the open end facing the back of the machine's interior, if your machine has a "PowerScour" facility.
5 Place silverware in the silverware basket with sharp items pointing downwards. Alternate the direction in which you load spoons to prevent them "nesting" together, which stops water reaching every surface.
Detergent and Rinse Aid
* 1

Place detergent in the dispenser just when you intend to run the wash cycle, not before. If you're using standard powder or liquid detergent, be guided by the hard-water and soft-water indicators. These are lines marked in the side of the dispenser. In areas with soft water, fill to the soft water line and in hard-water areas fill to the hard water line. If you prefer individual tablets, follow the manufacturer's instructions.
2 Add rinse aid immediately when the rinse aid indicator reaches the "add" level. Turn the cap on the rinse aid dispenser to "refill" and lift it away from the dishwasher. Pour rinse aid into the opening until the indicator reaches the "full" mark and replace the lid. Make sure the lid is tightly in place.
3 Adjust to a higher setting on the arrow adjuster, located inside the dispenser, if you feel more rinse aid is needed during a wash cycle. You can do this by inserting a flat-blade screwdriver into the center of the adjuster.
Starting the Wash
* 1 Check that the spray arms can rotate freely before closing up the dishwasher.
2 Turn on the hot faucet at the sink closest to the dishwasher and let the water run until it is hot.
3 Close the door firmly and select the wash cycle you wish to use. Depending on which model you are using, you may wish to activate additional options during the cycle such as "Power Scour." These options should also be selected at this stage.

Thanks.

It sounds like you need to check the filters and clean them. It’s usually pretty simple to do but makes the dishwasher run like new. I think that it might be obstructed somewhere preventing it from being able to fully rinse the dishes. Is it draining all the water after the cycle has finished?

www.dishwasherfilter.com will solve your problem. its hard water causing the spots and not your dishwasher.

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

When ever I hear of a dishwasher "suddenly" not cleaning properly, with spots on the glassware and soap not dissolving:

-If the spots are white patches, you can suspect the DW detergent powder. Go buy a name brand of detergent powder and I bet you will see a dramatic improvement. You may need to run a cycle or two with white vinegar added (up to two cups added after the DW starts, fills and begins to wash.)

-If the spots are a film / slime, you should suspect that the heating element. For the dW to be effective cleaning and rinsing clear,the DW needs to raise the water temp during the ~wash~ cycle (after the detergent dispenser has magically opened. After the heating element has been replaced, you will see an immediate improvement.

-If you had reported food debris sticking to dishes, (which you didn't), the first thing to do is clear the holes in the wash arms, then open the sump area , remove the filter assembly and inspect closely with a flashlight to locate blocking debris. (watch out for broken glass!) Inspect the impeller and make sure it is not damaged. If after assembly, the cleaning is still poor, it is time to replace the wash pump / motor assembly.

Good Luck! Ask more questions as needed!

Make sure your water is at least 120 degrees and change to a dishwasher detergent with a water softener and a rinse aid in it.

Run the unit with no soap, after about 5 min. of run time open door and check to see if water is clear or soapy,If soapy then you are having an oversudsng issue.When your washer gets to rinse cycle, your unit (if oversuding),will be rinsing with soapy water and the the drying cycle bakes the soap on dishes.You might be having a white film on your clear glasses.Cut down on soap especially if you have soft water.powder soap is best.Your dishwasher will fill , wash , the drain.Its what you put into it that will cause dishes not become clean.

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.
