I have seen this problem before on a couple of dishwashers.

How are the dishes doing? Are they coming out clean, or do some of them "fail".

If you rinse the dishes before putting them in the dishwasher, it may be hard to detect "failure" to clean. Try not rinsing the dishes once and run them through a cycle. My guess is that the "failure" rate will be high.

The problem I have seen is that the dishwasher water input filter is either clogged or the water-full sensor is "telling" the unit that there is enough water in before it actually fills properly.

So, some water can get in, but not enough to properly wash the dishes and dissolve the soap.

On the appliance repair sites they have parts breakdown details and what you are looking for is an input valve assembly -- the point just after the water line connects to the dishwasher.

Now the valve may be OK, but the feedback system could be bad.

(On a Bosch dishwasher the valve IS the feedback system and the filter.)

Any filtering or "water full" signal will feed back to that valve.

If you get inside that front lower panel, be sure to turn the electricity off first 'cause if you get crosswise in that area you could end up with a 'shocking' experience!

good luck

Why does a lot of detergent remain in the soap dispenser after a washing cycle is complete


Was the dispenser cup wet when you added detergent?
Make sure the dispenser cup is dry before adding powdered detergent. If dispenser cup is wet, the detergent can clump.
Is the cycle incomplete?
If the previous cycle did not complete, the detergent can become caked in the dispenser cup if it is left sitting in the dishwasher.
Is the detergent old?
Older detergent exposed to air will clump and not dissolve well, which will cause the dispenser door to stick to the detergent. Replace detergent if necessary and store the detergent in a tightly closed container in a cool dry place.
Is the water temperature too low?
For best washing and drying results, water should be 120oF (49o C) as it enters the dishwasher.
Were items blocking the dispenser that kept it from opening?
Items blocking the detergent dispenser will keep it from opening. Make sure water action can reach the dispenser.
Detergent guidelines
  • Use automatic dishwashing detergent only.
  • Other detergents can produce excessive suds that can overflow out of the dishwasher and reduce washing performance.
  • Store tightly closed detergent in a cool, dry place.
  • Fresh automatic dishwasher detergent results in better cleaning.
  • Add detergents just before starting the cycle.
  • The amount of detergent to use depends on the hardness of your water and the type of detergent.
  • If you use too little, dishes won't be clean.
  • If you use too much in soft water, glassware will etch.
  • Suggested fill amounts are for standard powdered detergent. Amounts may vary if you use liquid or concentrated powdered detergent. Follow instructions on the package when using these detergents.
  • Water hardness can change over a period of time. Find out your water's hardness by asking your local water department, water softener company, or county extension agent.

Soap dispenser problem?


Check the water supply. Start cycle then open the door after it fills and check water level and spray action. If everything is soaking wet, there is probablyl a pizza pan blocking the soap tray.

My whirlpool dishwasher soap dispenser is apparently not opening during cleaning. I find dirty dishes and clumps of soap in the hopper. Whirlpool quiet partner II


I bet your clumps of soap began with the beginning of the use of a different DW detergent powder.

Try this (trust me) Go buy a box of brand name Dishwasher powder (e.g. Electrosol or Cascade) Use it for two loads of dishes and report your results back here. OK?

Soap hardens in the dispenser and dishes don't come clean


Either your dishwasher is not getting the water hot enough to dissolve the powder, or you need to switch brands. Try a liquid/gel type of dishwasher detergent.
Try stopping the washer a few minutes after you start a wash cycle. Open the door -- if there is a lot of steam coming out at you, it's not the water temperature. If there is no steam, your dishwasher is not getting hot water and/or the heating coil is not working.

2 things will lead to soap not dissolving, first is cold water, so make sure you have hot enough water. second and more likely is the dispenser is not opening at the proper time , instead fully opens at end of cycle during the dry cycle never even getting wet, and washing dishes with no soap, id replace the dispenser or make sure your not stacking items in front of dispenser hindering the opening. also powder is best, tabs and gelpack put undo stress on the dispenser door not always allowing full operation...

Dishwasher problem


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.

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.

Dishwasher not cleaning well


clean the dispensor assy around the spring door hinge witha vinegar water solution . liquid detergent has a tendency to not fully break if your water is not hot enough, causes doors to stick, reccomend running hot water before starting d/w, and using a quailty powder( not tabs) detergent

Before taking anything to bits, check you aren't just loading the machine in such a way that something (for us, it's usually a frying pan) is stopping the soap dispenser from springing open all the way. A.
