Hi!

Please run the machine without detergent for 2-3 washes. Also try using a little hot water. Also, don't used cleaner and softener together but add softener on the last rinse.

    Your dishwasher is not getting the water hot enough to dissolve the powder, or you need try a liquid/gel type of dishwasher detergent.



    Check if the water shut off valve under the sink is completely open.

    Try stopping the dishwasher a few minutes after you start the cycle. Open the door -- if there is steam coming out then it's not the water Temprature issue. If there is no steam, your dishwasher is not getting hot water and/or the heating coil is not working.



    Also check for Clogged spay arms, there should be no debris blocking the holes inside each spray arm.



    Please revert for further clarifications.



    Thanks

Dishwasher tablet not dissolving during wash cycle


I am not sure if you can use dishwashing tablets with this model of dishwasher. These are designed mainly for powder only - you should be able to shut the detergent compartment door before starting the dishwasher.

Make sure the compartment is not blocked preventing inlet water from circulating through.

I have a Neff Dishwasher S5443X2 and the dishwasher tablets are not dissolving. The tablet door is open when the machine finishes but most of the tablet remains. We tried using detergent but still the same...


Either:
  1. the water does not get into the dishwasher open the dishwasher 3-4 times during cycle, you should see some water at least once, if not - check water valve, water level float and water pressure.
  2. the pump is clogged - there is water, the motor will run but no water is circulated. Check pump filters, check chopper and impeller.
  3. motor in main pump is not working - could be caused by something stuck on the impeller or chopper or could be a problem with the motor itself or control board. Check if line voltage is coming to the motor during wash/rinse cycle.
Good luck,

Soap not dissolving in dishwasher. stays in compartment


Hi, dishwasher detergent stays in the compartment because Bosch has designed a gap at the top of the compartment that feeds water onto the detergent before the cover opens. This has possibly been done to soften up deteregent tablets and help them dissolve.

The result is a solidified mass of wet detergent that doesn't come out of the compartment when it opens, and slowly dissolves onto the dishes leaving them coated with alkaline detergent at the end of the cycle. The residual lump of detergent is in the compartment or on the bottom of the dishwasher (refer photo).

The solution is to remove the compartment cover and look for the small gap at the top of the compartment as in the photos. Clean the surface and fill the gap with epoxy glue. This will keep the detergent dry until the cover opens, allowing the detergent to fall freely out of the compartment._1583.jpg

Either:

1. not enough water gets into the dishwasher. open the dishwasher 3-4 times during cycle, you should see some water on the bottom at least once, if not - check water valve, water level float and water pressure.

Detergent tablet not dissolving.


sometimes the dispenser doors are not designed for tablets, and they don't let enough water in to dissolve them....next time you wash; put the tablet in one of the silverware compartments....should do the trick. and leave the dispenser door for liquid detergents only.

if this is helpful please click the correct button. thanks

Dishwasher 3 in 1 detergent tablet not dissolving.


I believe that the instructions for using these 3-in-1 tablets is to place it in the open dish detergent cup, rather than in the closable compartment, since the tablet needs to get doused by a lot of water in oder to fully dissolve and be effective in getting the dishes clean.

Since the tablets are designed to dissolve more slowly, they are able to be used for the entire range of washing cycles. If it's a constant problem and you don's have an open detergent cup below or next to your closed detergent dispenser, just toss it into the bottom of the dishwasher instead.

The reason that the tablet isn't getting dissolved fully is because the door is preventing the tablet from dropping all the way out and the door is shielding the tablet from quite a bit of water spray.

Another option is to take a look at your owners manual for the dishwasher and see if they recommend these all-in-one tablets versus regular powered detergent and liquid rinse aid.

Hope that helps and best regards!

Dishwasher detergent "pacs" dont disolve anymore


Try reversing the bottom dish rack, it's likely blocking the dispenser door because it's put in the dishwasher incorrectly. Also check if there is anything in the back of the rack preventing it from going all the way in.

Tablet falls out & doesn't dissolve especially on fast cycle


Hi and wlecome...
You should not use anything other than powered dishwasher detergent in these products. They are not designed for tablet-style detergents. The reason is because the dispenser does not "open" during the wash cycle like you would see on a conventional dishwaser. The incoming water pours over the detergent and releases the mixture out the bottom of the dispenser.

Bosch Exxcel Auto Option/Detergent tablet does not dissolve?


It seem that your DW drain it's water by syphon action. Check if the drain hose is properly installed as a U shape; otherwise the DW can drain itself at any time, leaving the soap undissolved .

Tablet door dosn't open during cycle


It sound like a detergent cup issue (the door doesn't open at time) A very simple test for it is to place a tablet on the bottom of the dishwasher for a full cycle and to see what happen to the tablet. In case the tablet will be dissolved : - The detergent cup can become clogged with old dried detergent that prevents it from opening at time. Sometimes just cleaning the cup takes care of the problem. - The detergent cup opened by a bi-metal switch or a wax motor located inside your dishwasher door(behind the detergent cup). If cup's cleaning will not solve the problem, you should replace the bi-metal switch or the wax motor (depend which of them is used in your machine). Good luck !
