Bosch dishwasher not cleaning bottom rack

The dishes on the bottom rack are suddenly not getting clean. We have taken the bottom sprayer off and ran water through it and there doesn't seem to be a obstruction. What do we do next?

SOURCE: Top rack dishes have grainy particles on them after washing and will not come clean.

Run the dishwasher and observe the spray arm,if split it will spray water down: Also check water in tub, is it filling up sufficiently to get near the heater? If it has a upper spray arm does it spray water? If not you may have a clogged upper spray arm.

SOURCE: Top rack remains dirty

spin the top rotary arm to make sure it spins freely also take it off to see if its blocked (run it under tap) check all other filters too and when you load dishes make sure they do not obstuct top rotary arm if none of this works then it's time for an engineer im affraid good luck

We were told by Bosch to not use lemon scent. Use the original generic soap with NO sprakle or smell because the jet dry does the rest. Just let the soap be soap. Hopes this helps.

SOURCE: dishes not washing clean

check water level in machine
may be not filling enough and the wash pump is starved from water thus not pushing water to upper arm
drain water from machine dismantle and clean out air tube to pressure switch take off air tube at pressure switch and blow back into sump then pinch air tube with fingers to stop air from flowing back up tube then refit to p/s
run and see if that solves problem

Yes there is the Water Div valve, it diverts the water between the wash arms.

My dishwasher doesn't clean the all the dishes, esp on top rack

Check the jet holes on the sprayer arms. The outside holes usually plug first from calcification and centrifugal force causing only the center areas to clean. Remove these arms and shake out all of the "little white rocks" and then run the machine empty with a de-calcifying cleaner.

I have a Kenmore dishwasher, purchased in 2000, it is not cleaning the dishes on the top rack, just happened all the sudden.

You should check to make sure that the lower sprayer is extending to spray the bottom of the top rack and that water is being pumped up to the top sprayer. You will need to take the dishwaher out of the cabinet to test.

I once had gunk in the rotating sprayer itself that was blocking the dispenser opening properly? I reckon a thorough cleanse with a dishwasher cleaning detergent (the one that takes a super wash to do it) and check the joke a chicken bone was in one of them!!

I don't beleive my sprayer arm is working on the bottom of DW

The problem is hard water and your softener must not be taken it all out. There is a new product out called the dishwasher filtration system. It filters the water before it enters your dishwasher. It works amazing and has a money back guarantee. You will love the way your dishes look after the first load. It is also very affordable (like 70 bucks). Go to to find out more info.

Top rack whisperquiet dishwasher no water
I know this isnt the same model, they dont carry your manual as of yet. But it does have some suggestions to look at on page 17. I had the same problem and I looked really carefully and found my sprayer arm was blocked. I cleaned it out and havent had a problem with it again. I do check it regular now.

My whisper quiet dishwasher is not cleaning the top rack dishes

I'm having the same problem. Did some testing and found that the sprayer on the top rack is not even moving and hence not getting any water. Not sure what to do.
