Question about Westinghouse 24 in. MDP531 RF Free-standing Dishwasher

Powder not dispersing

Our Westinghouse freestanding dishwasher (906) doesn't disperse the powder properly. When the cycle finishes the powder is all caked together and stuck in powder holder. I think it might be that water is getting to the powder holder before it opens and that makes to stick in there or maybe the lid of the powder holder isn't opening at all during the cycle. Any help/advice would be great.

    We have cleared all the filters, removed rotator arms (found no blockage) and replaced.

Possible the wash arms are not rotating - a common cause of powder not being taken. check by opening the door when in use and look to see if arms rotate. if not, then remove the arms and clear the jets especially the angled jets at the end which cause the arm to rotate

Dishes come out feeling gritty. Using Finish doesn't help

If you open the door immediately after the dishes are washed, and before the "dry" cycle, is the water hot enough to have "steam" coming out of the machine?
You should be able to feel the heat.
If not, perhaps the water is not getting hot enough to dissolve the dishwashing powder.
Could you try using a liquid soap once and see what happens?
Be blessed.

Printer showing TONER LIFE END even there is 70% of powder balance

go to this site and read carefully

then gently remove the drum , place it in a plastic bag -- seal the bag , so you do not get powder all over you .. with both hands holding each end of the bag , rock it lightly back and forth. this will allow the poweder to be equally dispersed inside the drum .... remove the drum from the plastic bag. You may need to clean off the black powder from around the toner before placing it back to avoid powder in the printer area.. use old and very damp cloth then place it back into the printer ..

i hope this helps -- please rate me

Soap powder will not dissolve in tray

Make sure you have the powder in the correct compartment, and that there is no blockage or obstruction to prevent the powder going down, to prove this, pour water into the tray with some powder in , and see if it takes it down.
Also make sure that there is adequate water pressure to take the powder down
These are really the only things that could prevent dispersal of the powder.
Hope this helps.

Every time I use my Zanussi Aquacycle, the water does not disperse from the washing powder drawer. This means I have to keep taking the drawer out, draining it off and putting it back before I use the...

It sounds as thiough the hose that lets the water into the drum from the dispenser is blocked with undesolved soap powder, you need to remove the top cover, and clear the blockage in the hose.
Please rate my solution.

Simpson brand dishwasher won't disperse detergent tablet

The soap dispenser drawer is supposed to open during the cycle. Try first to understand if the drawer is opening or not during cycle.

If the drawer is not opening, then check if the opening mechanism is stuck, if it is blocked by dirt and soap, if it is broken, or if something, for examble a basket too close to dispenser drawer is preventing the drawer from opening.

Some dishwasher works only with powder, in that case indications are given on the owners manual.

If the drawer opens and the table, or powder is still staying stuck in the drawer, then that means that the spray does not have enough power to solve the tablet.
In that case check spray arms and impeller pump.Also check water temperature.

If the problem is also happening with powder, then it is probably a drawer not opening on cycle.

Dishwasher leaves soap in dispenser.

Hi Dirty Dish gang.
After having 2 appliance repairmen here, I now have the latest scoop on our dishwasher problems, $200 later!
Los Angeles IS currently having hard water issues. Also, all the new cleaning gels etc. are actually a cause of our dishwasher problems.  
So, here is what we need to do:
1. Use Cascade POWDER detergent only.  Make sure is is just "plain" no "scented" or "complete"  or gel, etc. (I have tried a phosphate free powder and gel and this is a cause of our problem as well!) 2. Use Jet Dry in the dispenser (set it to a 2-3 opening) 3. Make sure water is at least 120 degrees 4. Only run dishwasher on "normal" setting.  All others just run it longer, hence causing more water stains. 5. Do not pre-wash dishes! You can knock of chunks with a "non" soapy brush, but don't rinse (the oils actually help to clean the dishes) 6.  Do not wash sponges in dishwasher.
Acid Wash: The repairman just gave my washer an Acid Wash today. It says it is an acid derived from lemon, I got mine from Carters appliance in Torrance, CA for about $19. I am to run a normal cycle with the above mentioned Cascade after this "acid cycle" is finished.
If you are still having problems:
Monthly maintenance: Glass Magic: Buy a box of Glass Magic (near the Cascade)  Use 1 Tbsb in main detergent compartment of dishwasher along with the Cascade, till washer starts working again. White Vinegar: You can run an empty dishwasher with white vinegar once a month.  Fill a bowl with 2 cups vinegar and place on bottom rack.  Then run as a normal cycle...this allows vinegar to disperse slowly.
So far it seems to be working.  Good luck.

Dispensing tray is not opening at right time in cleaning cycle

unlikely to be dispensor opening at the wrong time. the powder is washed out by water squirting from angled jets at the end of the spray arm. check no blockage in spray arm - sometimes difficult to see. you may find also that the spray arms are not rotating for the same reason
