Re: Clogged water dispenser in Bosch dishwasher
Hi, Logmanup (slight bouts with dyslexia, sorry)
By "spinning water dispensers", I assume you mean the spray arms, right? OK... if they are getting clogged with debris it would be nice to know what kind of debris. Pieces of broken glass? Plastic? Lime scale? Iron? And yes, when they get clogged they won't rotate, won't allow pressurized water through and therefore won't clean the dishes.
For the purpose of this solution, I'll assume that there are little white particles clogging up the jets on the spray arms. This indicates hard water and lime scale build up.
Other than completely disassembling the entire motor/pump assy. (you really don't want to go there), the best way to clear this out of the system is to use an over the counter chemical called Dishwasher Magic or something similar. If the lime scale build up is really bad (and it sounds like it is), use a couple of bottles to start with and follow up with a bottle per month thereafter.
As an aside... If I assumed correctly about the lime scale build up, that means that it's also affecting other appliances as well. Mainly, your hot water heater. If you haven't done it before, please read this to perform maintenance on it. And a product something like this for your washing machine.
I hope this was helpful. Let us know if this works or not. If not, please write back and we'll go a little deeper.

Sometimes dishwashers become clogged with water minerals and they need to be cleaned of these minerals. White vinegar works pretty well. Place some white vinegar in the dishwasher , about one cup full, and also place white vinegar in the jet dry dispenser, and run dishwasher without any dishes in it. Maybe that will work.....
DISHWASHER NOT CLEANING WELL??
Here are 5 common reasons why not.
Improper Water Temperature
I can tell you from personal experience that water temperature has a direct impact on how well your family's dishwasher operates. If the water entering your dishwasher is not hot enough, your dishes are likely to come out coated with grease and dish detergent residue. As such, you will want to make sure that the temperature of the water inside your dishwasher is somewhere between the range of 120 degrees Fahrenheit and 140 degrees Fahrenheit. If it's not it could be a faulty heating element.
Based on my experience, a dirty dishwasher pump will also cause your dishwasher to produce less than stellar results. Therefore, you may want to consider cleaning your dishwasher's pump every six months. In many instances, it is an easy task to complete. In order to clean your dishwasher's pump, you'll most likely have to remove the dishwasher's spray arms. Once the spray arms are removed, you'll want to clean and inspect the pump's impellers, blades and pump guard. I should also mention that there are appliance companies that sell dishwasher pump repair kits should you notice that a part needs to be replaced. A basic dishwasher pump repair kit will tend to cost you $20 to $60 depending on your dishwasher's unique needs.
Dirty Spray Arm
Dirty spray arms may also be to blame. After all, if the spray arms' holes are clogged, the hot water won't be able to reach the dishes properly. A dishwasher's spray arms are very simple to clean. In order to clean them, you will need an old toothbrush and a bread twist tie that has been stripped of its paper. Use the toothbrush's bristles and the wire from the bread twist tie to unclog all the holes.
Broken Dish Detergent Dispenser
A broken dish detergent dispenser is another likely culprit when it comes to dish cleanliness problems. Sometimes the dish detergent dispenser's door will not open or shut properly, which prevents the dishes from getting nice and soapy. The good news is that most dish detergent dispenser problems may be solved relatively inexpensively. The cost of a replacement dish detergent dispenser will vary based on the make and model of your dishwasher. There are also instructional videos online that will help you with the installation of your dishwasher's new detergent dispenser.
A filter has an impact on a dishwasher's effectiveness as well. Hence, you will want to inspect your dishwasher's filter for obstructions. The location and type of filter will vary based on your dishwasher's make and model. I would recommend that you check out your dishwasher's operator's manual. It should contain instructions on how to clean your particular unit's filter as well as where you can order a replacement part if need be.
Make sure your water temperature is hot enough to dissolve the soap. Generally, the water temp. should be 140 degrees. Run some hot water at the tap before you turn on the dishwasher. This will assure that hot water is in the dishwasher as soon as you start it. Be certain that there aren't any large pieces in front of the dispenser tray. Sometimes casserole dishes, frying pans or baking pans can block the door and prevent it from opening.
Also, the sprayer arms might be clogged with bone fragments, peelings, bits of paper, etc. If this is the case, you'll need to remove the sprayer arm, flush and then check the jets. If you see "stuff" in the jets, they can be remove with tweezers.
Finally, make sure the upper sprayer arm hose is securely seated with the tube in the back of the dishwasher that carries the water up to the sprayer arm hose. If these two are not seated correctly, the water will not travel into the sprayer arm hose, the sprayer arm will not turn and your dishes will not get clean! I hope this helps. If it does, please come back to Fixya and rate my advice.
Look for debris in the holes of the wash arms. Is the soap dispenser opening? If so you probably have either no water in the machine or no ciculation. Also be aware sometimes a fill valve will work for the first few fills and then not work once it is heated up a little. And the valve could be clogged causeing low or no water to enter the machine.
Hi, Are you using Jet Dry Rinse Agent? It is very important to keep the washer supplied with this stuff. Otherwise, glassware will come out with a cloudy film and water spots. If you are using it, perhaps it is not being dispensed by the machine. I am having this trouble now, but my machine is about 10 years old, and has always turned out beautiful glassware unless it ran out of Jet Dry. Now, there seems to be a problem in my machine not dispensing it, and I was searching for a solution when I came across your posting. Baxterdog
check for leaks where the the top rack plugs into the rear. it might not be sealing. If your unit has the ability to change the top rack height check in the other position and see if it works. In my Samsung (Bosch in disguise) model The tube to the top rack plugs into one of two holes in the rear, depending which rack position I use. Something covers the hole not in use. Bosch uses two seperate pumps for washing and draining. So I don't think the pump could go partially bad. (This happens in other brands when the solenoid gets stuck between pump out and recirculate)
You possibly have several problems. The plunger is broken to the dispenser. You will have to disassemble the door to check the dispenser. Your water not draining is why the dishes aren't getting clean. Check to see if your drain hose is clogged. It may drain at a disposal or through a siphon gap which is mounted to the rear of your sink. Sometimes the siphon gap gets clogged and will cause drainage problems. It sometimes is located at the right or left rear of the sink and has a cap that sits about 3 to 5 inches high. Take the cap off and make sure there is no clog.
