OUR MAYTAG DISHWASHER HAS STARTED TO NOT CLEAN AS WELL AS IT HAD. THE GLASSES ARE STILL DIRTY AND PLATES ARE NOT FULLY CLEAN PLUS THE ITEMS FEEL LIKE THEY HAVE A GRITTY RESIDUE ON THEM. WE HAVE USED DIFF BRANDS OF POWDER, LIQUIDS AND RINSE AIDS AND STILL NO CHANGE.

add rinsing agent, increase temp & install a water softener.

Try using a dishwasher cleaner. You can get it at any supermarket that sells dishwasher soap.

If it is just glasses and coffee mugs that it refuses to wash maybe you should stop trying to wash these items in this dishwasher.
Could it have to do with the location where you put them? Maybe the direct water jet has a blind spot there while the reflected dirty water concentrates there. That may have to do with the shape of the vessel. I am just trying to make sense out of this unusual behavior. (I am thinking of some remarkable properties of parabolic and elliptic surfaces.)

it's generally not a good idea to put really greasy items in a dishwasher along with relatively clean items such as glassware and plates and cutlery, as most recent good quality dishwashers come with a soil sensor that ends the wash cycle once the dishes appear clean, and all the grease from your frying pan will cause the soil sensor to take longer to detect clean water.

The problem is hard water. Go to www.dishwasherfilter.com. They have a new product out that solves this problem once and for all. It filters the water entering your dishwasher and removes the hard minerals that cause these spots. Very affordable and guaranteed to leave your dishes looking amazing every time.

A water softner will not make the dishes any cleaner, it just makes it so they don't have water spots on them.
If the dishes are dirty, it is most likely that the nozzles (holes) in arms may be plugged.
Also check to make sure you are getting plenty of water to dishwasher. Make sure all water valves are full turned open.

If the control panel does not work all the time, it is very likely you have either a shorted wire, or a fualty main board which is very common in newer machines.

Remove all dishes and throw two cups of vinegar into your machine then run the complete pot scrubber cycle with the hottest water you can.

Always run the hot water into the sink until it is totally hot before you run your dishwasher.

Hi!!! 10 years is alot for a dishwasher..You could have a plugged drain pump.Check your drain pump.All make sure that the water inside your dish water is hot inside it should read over 100 plus..Good luck..

there is a new product out called the dishwasher filtration system. it actually filters the water going into your dishes. the dishes look dirty because your water has a lot of calcium and magnesium in it making them appear cloudy or dirty. the dishwasher filter reduces those minerals and my dishes look perfect now. no more dirty and grimy looking dishes. i also dont waste time washing them by hand before and after the dishwasher. hahaha you can get it at www.dishwasherfilter.com. use code DFMTEN and you will get 10% off. it fits right under your sink and is very affordable. you will be glad you bought this product. thanks

Things that have been known to exacerbate this problem are: 1. Putting too much food in the dishwasher - especially things like breakfast cereal, rice or couscous. Try scraping plates and pots thoroughly before loading them. 2. Not cleaning the strainer/filter - if not sure how to do this, check the owner's manual 3. Putting glasses in on their sides, rather than completely upside down - this creates a puddle of dirty water that can't get rinsed off and subsequently dries crusty. Sorry if the first three are insultingly obvious - but they are the most common causes of this problem. 4. Debris in the spray arms - you can usually get them off easily enough (though beware of left-hand threads on some models), then give them a flush through under the tap. 5. One or more spray arms put back on upside down (OK, confession here - I've only seen this happen once, and it was me that had done it. Took me weeks to realise). A.
