Dishwasher my dishwasher lately has not been cleaning well-the soap dispenser opens, but at the end of the cycle, most of the soap is all clumped in the dispenser, and there are food particles and film all over the dishes. Please advise what i could do to troubleshoot, as i do not want to call in a repairman at this point-Thanks!

If you are you using a liquid soap or packets that will be the main problem.If your unit fills with water circulates the water and drains the water,and also heaters are working then you probally need to change to cascade powder soap.The film on the dishes is soap.The unit has so much build up in it that when it gets to the rinse cycle it is rinsing dishes with soapy water.You need to get 2 medium bowls fill both 2/3 up with white vinager,place one in upper rack and one in lower rack and run unit on longest cycle letting the vinager splash out during wash.do this with no soap and no dishes.Having soft water will allow you to use less soap.

Hard water is the reason for the white film. There is a new product out at www.dishwasherfilter.com that is made specifically to fix this problem. It filters the water going only into your dishwasher leaving your dishes spot free with every load. It is very affordable and guaranteed to work or your money back. You will love the way your dishes look after the very first load.

Symptoms:
Dispenser lid is open. Caked powder at (what would be during normal operation) bottom edge of soap dispenser or caked powder fallen onto dishes or dishwasher bottom. There may be loose powder in rest of dispenser or spilled down inside door or onto dishes underneath dispenser.

Solution:
Keep the area around the soap dispenser lid clear when loading the top tray.

Explanation:
The soap dispenser needs to swing open during the wash cycle. In many dishwashers the top tray has an indentation as wide as the lid of the dispenser. This allows the top tray to be as large deep as possible while still allowing space for the dispenser lid to open. People often pack their dishwasher with things overhanging this gap.

During the wash cycle the catch will release but the overhanging cutlery or crockery prevents the lid from opening all but a few degrees. Some water will splash in but not enough to wash out the soap powder. The soap powder at the bottom of the dispenser will then cake.

When the front door is opened the spring loaded lid, which is partly open, will of course swing fully open and you'll be convinced that the lid opened normally during operation. If this is the problem then if you're very careful and open the door very slowly you can actually hear the lid flip open. Also, depending on when the lid opens, how far it opened during operation and how fast you open the door you may find soap powder spilled down to cover the dishes at the front or down the inside of the door. This happens when you first open the door and obviously there couldn't be loose powder there if the powder had emerged while there was water washing around. Seeing the lid open as you open the door is a lot harder but can be done on some machines.
