Whirlpool gu2200 dishwasher, the detergent

Possible fault with the dispenser Click this link : Detergent dispenser

Instructions Things You'll Need:

• Vinegar or lemon juice
• Gel dishwasher detergent

1. dishwashers have a rinse aid dispenser. If your dishwasher has this dispenser, fill it up periodically and it will release the appropriate amount of rinse aid automatically at the right time during the wash cycle. This will help your dishes rinse more cleanly.
2. Rinse aid in solid form
   Some older dishwashers or basic models do not have an automatic rinse aid dispenser. In this case, you can buy rinse aid in solid form that attaches to your dishwasher rack. Solid rinse aid can be hard to find in stores because it is not commonly used, but it can be purchased online.
   
3. Vinegar or lemon juice
   Appliance repairmen will tell you that one of the common problems they see with dishwashers is the buildup of excess detergent. If there is too much detergent in your dishwasher, your dishes will not rinse cleanly, no matter how good the dishwasher is or how much rinse aid you use. To clean the excess detergent that has built up inside your dishwasher, put 3 tablespoons of vinegar or lemon juice (concentrate is fine) in the empty dishwasher and run the dishwasher through a complete cycle with no dishes. Do this twice, for two complete cycles of the empty dishwasher with only vinegar or lemon juice added. The acid in the vinegar or lemon juice will break up the detergent that has built up in your dishwasher's interior.
   
   After you have cleaned the detergent buildup from the inside of your dishwasher, follow the steps below to keep the buildup from happening again and to help your dishes rinse cleanly and prevent residue from accumulating on the dishes.
   
4. Gel dishwasher detergent
   Switch to a liquid or gel dishwasher detergent. Any brand will do.
   
5. Fill one compartment half full Dishwashers will effectively clean dishes with much less detergent than manufacturers often recommend. The bleach in the detergent, combined with the extremely hot water used in the dishwasher wash cycle, will clean and sanitize your dishes completely, even in small amounts, and using less detergent helps prevent buildup and residue from accumulating on your clean dishes.
   
   Fill only one detergent compartment(the one that snaps closed) half full with gel detergent. Snap the opening closed and run your dishwasher as you normally would. Your dishes will come out sparkling clean with no buildup or residue, plus you'll save money by using less detergent!
   

Hi,

The scum, film and white residue problems have started since the reduction of phosphates in dishwasher detergents.

Here is a tip that will help you to solve the problem of films, residue, and scum in your dishwasher.

Dishwasher Residue and Film on Dishes

Try more or less detergent. Is rinse aid solution and detergent dispensers working properly? Otherwise, you may have an issue with quality of water.

Did you check the incoming water quality, regarding hardness!

If your washing machine supports salt addition technique, fill the appropriate box and fill the salt that is meant for washing machines. Salt works as a softener.

Finally check your rinse aid also for it's fill in the dispenser meant for it

The electric solenoid that opens the dispenser has failed. It is possible to replace it but you will probably have to disassemble the door to do it. An alternative might be to use a detergent tablet only in the open cup. It will partially dissolve during the pre-wash and what remains to dissolve in the main wash may be enough to get the dishes clean. Try this if the cost of replacing the solenoid is too high.

i suggest using detergent and jet dry....w/p doesnt sugg packets due to this issue

wash them by hand

You need to check your water temp after it enters the diswasher, it should be at least 120 deg when it get in the dishwasher. If it not then the detergent, food, and greese can't break down.

If you have dishes (typically cutting boards or really tall dishes) that block the dispenser door from opening, the water cannot wash out all the detergent during the wash cycle. Check to see that after loading the dishes, your detergent door has clearance.
