BOSCH DISHWASHER SHU33A DETERGENT DISPENSER WON'T POP OPEN

If your Bosch dishwasher's soap dispenser is not opening or draining properly, here are a few troubleshooting steps you can take:

1. Clean the Dispenser Area: Start by inspecting the soap dispenser area for any debris, soap residue, or obstructions. Clean the dispenser thoroughly using a damp cloth and remove any buildup that may be preventing it from opening or closing properly.
2. Check for Mechanical Issues: Examine the dispenser latch and mechanism for any signs of damage or wear. Ensure that the latch is engaging properly and that there are no loose or broken parts. If any components are damaged, they may need to be replaced.
3. Test the Dispenser Solenoid: The soap dispenser may be controlled by a solenoid that releases it at the appropriate time during the wash cycle. Check if the solenoid is functioning correctly by performing a continuity test using a multimeter. If the solenoid is defective, it may need to be replaced.
4. Verify Proper Detergent Usage: Ensure that you are using the correct type and amount of dishwasher detergent recommended for your Bosch dishwasher. Using the wrong detergent or excessive amounts can cause issues with dispenser operation. Consult your dishwasher's user manual for specific detergent recommendations.
5. Check the Drainage System: A clogged drainage system can prevent the soap dispenser from draining properly. Inspect the drain hose, drain pump, and any filters for blockages. Clear any debris or obstructions you find, and ensure that the drain hose is not kinked or bent.
6. Reset the Dishwasher: Try resetting your Bosch dishwasher by turning it off at the power source or unplugging it for a few minutes. This can sometimes resolve temporary issues and restore proper operation.

If the above steps do not resolve the issue, it may be necessary to consult the Bosch dishwasher's user manual for model-specific troubleshooting steps or contact Bosch customer support for further assistance. They can provide you with specific guidance tailored to your dishwasher model and help you diagnose and resolve the problem.

Proceed with this step:
Timer
check the timer, and the linkage see it is defective.
Bi-metal switch or wax motor
test the swithc or the motor for defective.
Detergent cup, itself
can be clogged, for to open.

sincerely. God bless you.

Hello, Yes the door should be open at end of wash,either the dispenser is faulty or the p.c.b. If you dont want to go to the exspense of new dispenser etc.Try putting tablet ( I presume you are using tablets ) in the cutlery basket.If you are using powder then it will have to be repaired.

Hope this helps.

Hi,


1. The most common problem with the detergent doors on KitchenAid dishwashers is that they either don't open during the cycle or open only halfway. Before looking into more complicated repairs, make sure that the door is able to open. Check the seal around the door and the door latch for soap- and food-related gunk, and scrub it off if present. Sometimes this can keep the detergent door from operating properly. Consider switching detergents, as some liquids and pouch-style dish detergents can gum up the detergent dispensers. Also, make sure that there is nothing blocking the detergent door when the dishwasher is loaded. Because of the location of the detergent door, a large item such as a cookie sheet or a pan can prevent the door from opening. Run the dishwasher through a cycle without anything placed in front of the detergent dispenser and see if that solves the problem.
Broken Timer
2. KitchenAid dishwashers rely on an internal timer to complete the wash cycle properly. When this timer malfunctions, certain steps in the wash process (such as the release of soap from the detergent dispenser) can be interrupted. If the dishwasher detergent door is either not opening or appears to be opening late in the cycle, this is likely the mechanical culprit. A broken timer isn't something that's simple to replace without knowledge of dishwasher repair, so it's best to consult a professional if you suspect that this is the problem.
Malfunctioning Door Components
3. For the detergent door to function properly, all of its mechanical components must be in working order. Older dishwashers' detergent doors rely on a spring-loaded hinge to pop all the way open when the timer gives the signal. If the door doesn't swing all the way open instantly when it's manually released, the spring may need to be replaced for the dispenser to operate properly. If the particular model is newer and does not rely on a spring to open the door, chances are it either uses a wax motor or a bi-metal switch to release the detergent door at the appropriate time. If either of these components is dying, that can mean that the detergent dispenser will not operate properly.

I've been told we can replace the dispenser. See AppliancePartsPro.com. Part AP2834000

Not a solution but exactly the same problem. I should have sent the machine back (I bought mine about 2008 too) but by now, 2010, the machine is a complete waste of time and money. The soap dispenser fails to open every time, wasting money, water and my patience because I then have to hand wash after all. will try the suggested oil trick, but it was obviously a bad design to start with.

sounds like you are not getting enough or any water a check the water level when it fills... let me know

Behind the dispensor door there is a small selanoid you will need to replace this, test to see if its open circuit, alternatively you can just place the detergent in side the machine before you put it on a wash cycle is this would have the same effect. the only cycle you can not do this on is the one with the prewash, I think its number 1.
