The detergent door opens but there is always detergent left in the cup at the end of the cycle . I have tried different cycles but the result is always the samw. Detergent running down the inside of the door.

Hi
White film deposits are observed if water is hard or when you are using more detergent than needed, try filling detergent cup half way. Try using white vinegar after the wash cycle is complete, run a complete cycle. Also turn down the heat on the hot water fed to the dishwasher. Try using water softener for better results.
You can also add vinegar in the final rinse cycle. Make sure that your soap dispenser drawer is opening and closing fine.
Hope this helps... Please post back if more information is required.

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.

i have seen a problm perhaps similer to yours on several makes of dishwashers .. some washers have a flip up lid that normally covers the detergent cup .. if the upper basket is in the lower position (if its adjustable) then it blocks the flip up lid from opening ... this seems to be a design problem with several makes (probably all made by the same company ) .. if you put the upper tray in its up position then the door still doesnt open all the way but enough that the detergent gets washed out eventually .. that is if there is no large items just benieth that flip up lid .. if so that can block the water from getting into the detergent cup .. you end up with undesolved detergent still in the cup and in the washer at the end of the rince cycle .. very bad ... you may have a different problem .. for instance if the detergent cup door is not opening at all (bad opening mechanism) .. or if the pump screen is clogged then no water is circulated to desolve the detergent ..

bi-metal switch mulfunctions

With all modern front loading washers, you might find that the amount of detergent you need is much less than what is recommended by the detergent makers!

First, be sure you're using the He (High Efficiency) detergent and try using only 2 or 3 tablespoons of detergent. If you've heavily stained clothes, be sure to pre-treat them rather than adding more detergent. That should also help with the extra soap left in the clothes after a complete wash cycle.

Give this a try and adjust the detergent as needed to get the best results for your situation.

Hope you find this Very Helpful and best regard!

hello. i can help you.
When the detergent cup doesn't open, check these:

Timer
Bi-metal switch or wax motor
Detergent cup, itself
Timer On many dishwashers, a plastic actuator arm mechanically links the timer to the detergent cup. When the timer reaches the proper time in the cycle, the timer activates a lever that opens the detergent cup. If the linkage is broken or defective, the cup stays closed after you've closed it. Check the link and repair or replace it, as necessary.

Bi-metal switch or wax motor A bi-metal switch is a simple electrical device that deforms when electricity is applied to it. The degree of this deformation can be engineered to concise standards.

The timer energizes the bi-metal switch inside your dishwasher door--directly behind the detergent cup--when the detergent cup should open. When energized, the bi-metal switch deforms away from the detergent cup latch, which opens the detergent cup. If the bi-metal switch is defective, it may not deform enough to open the cup. If that happens, you need to replace it.

On some dishwashers, the bimetal switch is wired through the heating element or motor circuit. If the element is broken (or open), or if the motor is drawing low current because of a low-fill situation, the bi-metal switch doesn't open properly.

Newer dishwasher models use a wax motor instead of a bi-metal switch. It's a sealed unit with wax that heats up and pushes a piston through to open the door. The wax motor, controlled by the timer, mechanically opens the door.

Detergent cup, itself The detergent cup itself can become clogged with old dried detergent that prevents it from opening. Sometimes just cleaning the cup takes care of the problem. If not, you probably need to replace the entire cup assembly

The cycles times are too long If your dishwasher's cycle times are too long, check these:

Water pre-heating
Cycle not completing
Water pre-heating Your dishwasher may pre-heat the water. If so, and if the water entering the dishwasher is cool, the heater may take up to half an hour to heat the water.

To avoid the wait, increase the incoming water temperature before turning on the dishwasher. Do that by running the kitchen sink faucet until the water runs hot. Or increase the temperature of the hot water to the entire house at the hot water heater.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit.

Cycle not completing See "The cycle doesn't complete" section.

I doubt that the user manual covers de-liming the Hobart Dishwasher.   If I owned this (fine, expensive) dishwasher, this is what I would do.
1.) Discard any generic, ultra-cheap detergent.  Stop using gels or tablets and only use powders.  Buy a box of brand name powder (like Electrosol or Cascade)  You will be amazed how much difference that will make because the newest generics have mineral bulk added that build up faster then hard water does on both the stainless steel enclosure plus the silverware and even plates.  White patches.  I LOVE generic products and saving money, but low end dishwasher powder is one place I no longer choose a generic product.
2.) Add two cups of white vinegar to the empty dishwasher and leave it there until the morning.  Run a quick cycle with no detergent added.  The vinegar will be pumped out immediately after you begin this quick cycle.
3.) As soon as the dishwasher fills with water during that quick cycle and begins a wash cycle, add two cups of white vinegar and close the door and allow to run the full wash cycle.
4.) When the dishwasher finishes the drain cycle and begins to fill again, open the dishwasher and check the enclosure for remaining "lime" deposits.  If they remain, keep adding 2 cups white vinegar each time the dishwasher refills and begins to wash/rinse again.
You should be delighted with the results. Long term, you should consider adding a whole house water softener and then reduce the amount of dishwasher (and laundry) detergent by one half.  Amazing increase in quality of life by adding a water softener.  You will be delighted.
Please post back with you results, OK?  Good Luck!

Hi,
There are three common problems that cause the Soap Dispenser or Cup not toopen. I have a tip that will explain these problems in detail....

hi
the dispenser will always open when the washer goes through it's regular cycle. I would recommend to only use powdered soap, that is what the washer was designed to work best with.
