Our Maytag quiet series 200 does not clean or rinse dishes properly. It leaves film all over cups and dishes. Water also seems not to be draining out. It is 6 years old

Maybe not enough water. Defective water valve could cause that

First check your rinse aid make sure you have some in there. I have been told that too much or too little of this can cause problems with etching glass and damaging dinnerware. . I would put a cup in right side up and wash a wash as usual and take the cup out and check that water after. Make sure your using a proper soap, and hot water is getting to your dishwasher. Or has it been full and not really coming out over a long period of time?
Another possibility is it is dirty inside the dishwasher, and not draining?

If it' is not cleaning then the water is not doing the work. Check the drain hole to the pump. It can be clogged and slowing water pressure in the wash cycles.

You need to check the drain system completely, look for plugged screens, pump impellers, valves and the drain hose. You need to witness a large volume of water flow during drain.

Look for plugged or restricted drain system and screens. Look at spray ports for debris.

My Quiet Series does the same thing and I wondered if the orange flapper has gone bad and lets the dirty water drain back from the hose sloping up to the garbage disposal. Did you get an answer to this question? The dishwasher seemed to work fine and then it suddenly started leaving food particles on the glasses.

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.

under the unit where the water line connects,this is where the filters are.disconnect the water line take the fitting off that the line was hooked to,screen is there under fitting.

Buy a name brand powder (like Electrosol or Cascade) and use less than full in the dispenser cup.
Do not use gel or tablet, ever.
Final option: (the perfect fix, expensive, but worth it... install a whole house water softener and cut the use amount of detergent in half that you use in both your dishwasher and clothes washer. You will love it.
If problems continue, have the heating element checked/replaced. When it fails, you will always get film/residue on dishes, especially your glassware, even if your water heater is set to the proper temp of 120 degrees.
Good Luck!

I had the same problem with my Maytag Quiet Series 1 dishwasher until I read the comment left by the guest on June 1, 2008. I tried his suggestion about the rinse cap adjustment and WOW it WORKED. No more growling noise. Thanks you saved me a service call.
